Abstract:
The treatment of industrial wastewaters collected from petrochemical works, gypsum plant, and printing and dyeing mill, was investigated at atmospheric pressure in air discharge plasma. The degradation effects of organic contaminants in water were compared for the printing and dyeing wastewater under different discharging conditions and for the wastewater from the other two plants under the same discharging conditions. The influences of several factors on chemical oxygen demand (COD) remove rate were studied experimentally. The results showed that the treatment effects for the same industrial wastewater differed significant under different discharge conditions. There may be a suitable discharge plasma treatment to specific industrial wastewater. Due to the removal rates of COD of industrial wastewaters with discharge plasma isn’t very high, therefore the discharge plasma water treating needs to combine conventional water treating methods or addition other catalyst to effectively remove organic pollutants in wastewater and obtain the expected treatment effect.

Abstract:
SITEL, Integrated Wastewater Treatment System of South Petrochemical Complex, has been processing liquid wastes from this industrial area since November 1982. The Complex consists of an olefins plant and some second-generation plants that produce mainly thermoplastic resins. In this paper a comprehensive appraisal is presented of the operation of SITEL during the years 1985-1986. Data on the raw effluents produced by the individual contributors are presented, together with information on removal efficiencies of all parameters monitored throughout the different units and phases of treatment. A comparison between design characteristics and actual operational data of the system is also provided. Attention is drawn to results of bioassays and other peculiar methods of ecological and biological monitoring adopted at SITEL. This special monitoring routine shows that the tertiary treatment phase (consisting of eight waste stabilization ponds) accomplishes reduction of sublethal effects from the effluent that are not detected by conventional physico-chemical analyses. Data on priority pollutants are also presented, showing a reduction of the contents of most of these contaminants by the secondary (activated sludge) phase of treatment. Since the final effluent is applied on land, data on quality of underground water are also presented together with data on the quality of the nearest river. These are not appreciably altered by the final effluent from SITEL, except for certain parameters associated with dissolved ions that are mobile in soil, i.e., Na, Cl−, SO4−− and TDS. Comments on interesting cases of negative removal efficiencies are presented. Most of them can be ascribed to unique characteristics of the treatment system. Comparisons between operating costs of SITEL and data provided by other authors are also made. It is concluded that these costs are not high and can be reduced if more industries are installed in the South Petrochemical Complex and connected to SITEL. As a whole, the plant has been operating successfully with a high benefit/cost relationship.

Abstract:
Cost-effective pretreatment of highly concentrated and bio-refractory petrochemical wastewater to improve biodegradability is of significant importance, but remains challenging. This study compared the pretreatment of petrochemical wastewater by two commonly used chemical advanced oxidation technologies (Fenton and ozone oxidation), and the mechanisms of biodegradability improvement of pretreated wastewater were explored. The obtained results showed that in the Fenton oxidation system, the COD removal of petrochemical wastewater was 89.8%, BOD5 decreased from 303.66 mg/L to 155.49 mg/L, and BOD5/COD (B/C) increased from 0.052 to 0.62 after 60 min under the condition of 120 mg/L Fe2+ and 500 mg/L H2O2, with a treatment cost of about 1.78 $/kgCOD. In the ozone oxidation system, the COD removal of petrochemical wastewater was 59.4%, BOD5 increased from 127.86 mg/L to 409.28 mg/L, and B/C increased from 0.052 to 0.41 after 60 min at an ozone flow rate of 80 mL/min with a treatment cost of approximately 1.96 $/kgCOD. The petrochemical wastewater treated by both processes meets biodegradable standards. The GC–MS analysis suggested that some refractory pollutants could be effectively removed by ozone oxidation, but these pollutants could be effectively degraded by hydroxyl radicals (•OH) produced by the Fenton reaction. In summary, compared with ozone oxidation, petrochemical wastewater pretreated with Fenton oxidation had high COD removal efficiency and biodegradability, and the treatment cost of Fenton oxidation was also lower than that of ozone oxidation.

Abstract:
The objective of this project is to study the advanced treatment technique for the secondary effluent from petrochemical wastewater treatment plants in order to meet requirements for the reuse of industrial wastewater. Based on the characteristics of the secondary effluent of petrochemical wastewater, a direct filtration process with highly effective filter is selected and designed. The test results indicate that the process can achieve good results in turbidity and COD removal. It can meet the need for the industrial reuse of the secondary effluent of petrochemical wastewater as the turbidity value of effluent is less than 3 and COD of effluent is less than 40 mg/l. A great economic efficiency is obtained. The filtration system costs low because of the longer operating cycle (14-24h). It is a creative achievement in the reuse of petrochemical wastewater, and is the pioneering study in China.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO
A indústria petroquímica constitui um dos mais importantes setores industriais no Brasil. A grande diversidade dos processos de fabricação praticados faz aumentar a necessidade de caracterização dos efluentes gerados em cada planta industrial. Em geral, os efluentes apresentam elevado teor de matéria orgânica, cuja remoção é necessária para atender às normas técnicas de descarte de efluentes industriais. Um dos processos de tratamento utilizados é a coagulação química seguida de tratamento biológico. Na coagulação química, sais de alumínio ou ferro são usados como coagulantes. Devido às grandes flutuações de carga orgânica, as quais dificultam a dosagem do coagulante, buscam-se alternativas para aprimorar o tratamento. Neste contexto, a eletrocoagulação pode servir como alternativa à coagulação química ou como pré-tratamento. O presente trabalho consistiu de ensaios de coagulação química (Jar Test) e de eletrocoagulação em escala de laboratório, utilizando efluentes gerados em uma indústria petroquímica fabricante de borracha sintética. Os ensaios permitiram comparar as eficiências de remoção de matéria orgânica por eletrocoagulação e por coagulação química, bem como comparar as eficiências desses tratamentos em escala de laboratório com aquelas obtidas na etapa de tratamento físico-químico (coagulação química e floculação) da ETEI - Estação de Tratamento de Efluentes Industriais da indústria citada. Em todos os casos, as eficiências de remoção de carga orgânica foram avaliadas pela DQO (Demanda Química de Oxigênio). Nos ensaios de coagulação química em laboratório, utilizou-se como coagulante o sulfato de alumínio. Os parâmetros investigados foram o pH ótimo de coagulação e a dosagem ótima de coagulante. Os ensaios do processo eletrolítico foram realizados em batelada com eletrodos de alumínio. Os parâmetros investigados foram a temperatura, o potencial aplicado, o pH inicial, a distância entre eletrodos, o número de eletrodos e o desgaste dos mesmos. As eficiências de remoção de DQO pelo processo de eletrocoagulação apresentaram valores até três vezes maiores que a média mensal obtida na ETEI da indústria em questão, pelo processo de coagulação química e floculação, no período da coleta das amostras, indicando a possibilidade de aplicação do tratamento eletrolítico ao efluente estudado.
The petrochemical industry constitutes one of the most important industrial sectors in Brazil. The great diversity of processes of manufacture makes to increase the necessity of characterization of the effluents generated in each industrial plant. In general, the effluents presents high grade of organic matter, whose removal is necessary to expect to the technical standards of discarding of industrials wastewaters. One of the used processes of treatment is the chemical coagulation followed by biological treatment. In chemical coagulation, aluminum or iron salts are used as coagulants. Because of the large fluctuations of organic load, which makes difficult the dosage of the coagulant, alternatives are being looked for the improvement of the treatment. In this context, the electrocoagulation may be an alternative to the chemical coagulation or can serve as a preliminar treatment. The present work consisted of assays of chemical coagulation (Jar Test) and of electrocoagulation in scale of laboratory, using effluent generated in a petrochemical industry manufacturer of synthetic rubber. The assays had allowed to compare the efficiencies of removal of organic matter by electrocoagulation and chemical coagulation, as well as comparing the efficiencies of these treatments in scale of laboratory with those gotten in the stage of treatment physical- chemical (chemical coagulation and flocculation) of Industrial Effluent Treatment Station of the cited industry. In all the cases, the efficiencies of organic load removal had been evaluated by the COD (Chemical Oxygen Demand). In the chemical coagulation experiments in laboratory, the aluminum sulphate was used as coagulant. The investigated parameters have been pH excellent of coagulation and the excellent dosage of coagulant. The assays of the electrolytic process had been carried through in batch with aluminum electrodes. The investigated parameters have been the temperature, the applied potential, pH initial, the distance between electrodes, the number of electrodes and the consuming of them. The efficiencies of COD removal for the electrocoagulation process reached values up to three times higher that the monthly average observed in the treatment station of the studied industry in the chemical coagulation and flocculation stage. The results indicate the possibility of application of the process in the treatment of the studied effluent.

Abstract:
Reaction water, a high-strength COD (chemical oxygen demand) petrochemical effluent, is generated during the Fischer-Tropsch reaction in the SASOL Synthol process at SASOL SynFuels, Secunda, South Africa. Distillation of the reaction water to remove non- and oxygenated hydrocarbons yields approximately 25 - 30 ML/d of an organic (carboxylic) acid-enriched stream (average COD of 16 000 mg/L) containing primarily C2 – C5 organic acids, light oils, aldehydes, ketones, cresols and phenols. Together with the Oily sewer water (API) and Stripped Gas Liquor (SGL) process streams, this process effluent is currently treated in ten dedicated activated sludge basins. However, the successful operation of these activated sludge systems has proven to be difficult with low organic loading rates (3.5 kg COD/m3.d) low COD removal efficiencies (<80 %) and high specific air requirements (60 - 75 m3 air/kg CODrem). It is hypothesised that these operational difficulties can be attributed to organic shock loadings, variation in volumetric and hydraulic loadings, as well as variations in the composition of the various process streams being treated. Due to the fact that the Fischer-Tropsch (Synthol) reaction water constitutes 70 % of the COD load on the activated sludge systems, alternative processes to improve the treatment cost and efficiency of the Fischer-Tropsch acid stream are being investigated. Various studies evaluating the aerobic and anaerobic treatment of Fischer-Tropsch reaction water alone in suspended growth wastewater treatment systems have proven unsuccessful. High rate fixed-film processes or biofilm reactors, of which the fluidised-bed reactors are considered to he one of the most effective and promising processes for the treatment of high-strength industrial wastewaters, could he a suitable alternative. The primary aim of this study was to evaluate the suitability of biological fluidised-bed reactors (BFBRs) for the treatment of Fischer-Tropsch reaction water. During this study, the use of aerobic and anaerobic biological fluidised-bed reactors (BFBR), using sand and granular activated carbon (GAC) as support matrices, were evaluated for the treatment of a synthetic effluent analogous to the Fischer-Tropsch reaction water stream. After inoculation, the reactors were operated in batch mode for 10 days at a bed height expansion of 30% and a temperature of 30 ºC to facilitate biofilm formation on the various support matrices. This was followed by continuous operation of the reactors at hydraulic retention times (HRTs) of 2 days. While the COD of the influent and subsequent organic loading rate (OLR) was incrementally increased from 1 600 mg/L to a maximum of 20 000 mg/L and 18 000 mg/L for the aerobic and anaerobic reactors, respectively. Once the maximum influent COD concentration had been achieved the OLR was further increased by decreasing the HRTs of the aerobic and anaerobic reactors to 24h and 8h, and 36h, 24h and 19h, respectively. The dissolved O2 concentration in the main reactor columns of the aerobic reactors was constantly maintained at 0.50 mg/L. Chemical Oxygen Demand (COD) removal efficiencies in excess of 80 % at OLR of up to 30 kg COD/m3.d were achieved in the aerobic BFBRs using both sand and GAC as support matrices. Specific air requirements were calculated to be approximately 35 and 41 m3 air/kg CODrem for the BFBRs using sand and GAC as support matrices, respectively. The oxygen transfer efficiency was calculated to be approximately 5.4 %. At high OLR (> 15 kg COD/m3.d) significant problems were experienced with plugging and subsequent channelling in the BFBR using GAC as support matrix and the reactor had to be backwashed frequently in order to remove excess biomass. Despite these backwash procedures, COD removal efficiencies recovered to previous levels within 24 hours. In contrast, no significant problems were encountered with plug formation and channelling in the BFBR using sand as support matrix. In general the overall reactor performance and COD removal efficiency of the aerobic BFBR using sand as support matrix was more stable and consistent than the BFBR using GAC as support matrix. This BFBR was also more resilient to variations in operational conditions, such as the lowering of the hydraulic retention times and changes in the influent pH. Both aerobic reactors displayed high resilience and COD removal efficiencies in excess of 80 % were achieved during shock loadings. However, both reactors were highly sensitive to changes in pH and any decrease in pH below the pKa values of the volatile fatty acids in the influent (pKa of acetic acid = 4.76) resulted in significant reductions in COD removal efficiencies. Maintenance of reactor pH above 5.0 was thus an essential facet of reactor operation. It has been reported that the VFA/alkalinity ratio can be used to assess the stability of biological reactors. The VFA/alkalinity ratios of the aerobic BFBRs containing sand and GAC as support matrices were stable (VFNalkalinity ratios of < 0.3 - 0.4) until the OLR increased above 10 kg/m3.d. At OLRs higher than 10 kg/m3.d the VFA/alkalinity ratios in the BFBR using sand support matrix increased to 4, above the failure limit value of 0.3 - 0.4. In contrast the VFA/alkalinity ratios of the BFBR using GAC support matrix remained stable until an OLR of 15 kg/m3.d was obtained, where the VFA/alkalinity ratios then increased to > 3. Towards the end of the study when an OLR of approximately 25 kg/m3.d was obtained the VFA/alkalinity ratios of both the BFBRs using sand and GAC as support matrices increased to 9 and 6 respectively, indicating the decrease in reactor stability and acidification of the process. Total solid (TS) and volatile solid (VS) concentrations in the aerobic BFBRs were initially high and decreased over time. While the total suspended solids (TSS) and volatile suspended solids (VSS) concentrations were initially low and increased over time as the OLR was increased, this is thought to be as a result of decreased HRT leading to biomass washout. The anaerobic BFBR using sand as support matrix never stabilised and COD removal efficiency remained very low (< 30 %), possibly due to the high levels of shear forces. Further studies concerning the use of sand as support matrix were subsequently terminated. An average COD removal efficiency of approximately 60 % was achieved in the anaerobic BFBR using GAC as a support matrix at organic loading rates lower than 10 kg COD/m3.d. The removal efficiency gradually decreased to 50 % as organic loading rates were increased to 20 kg COD/m3.d. At OLRs of 20 kg COD/m3.d, the biogas and methane yields of the anaerobic BFBR using GAC as support matrix were determined to be approximately 0.38 m3 biogas/kg CODrem (0.3 m3 biogas/m3reactor vol.d), and 0.20 m3 CH4/kg CODrem (0.23 m3 CH4/m3reactor vol.d), respectively. This value is 57 % of the theoretical maximum methane yield attainable (3.5 m3 CH4/kg CODrem). The methane yield increased as the OLR increased, however, when the OLR reached 8 kg/m3.d the methane yield levelled off and remained constant at approximately 2 m3 CH4/m3reactor vol.d. Although the methane content of the biogas was initially very low (< 30 %), the methane content gradually increased to 60 % at OLRs of 20 kg COD/m3.d. The anaerobic BFBR using GAC as support matrix determined that as the OLR increased (>12 kg/m3.d), the VFA/alkalinity ratio increased to approximately 5, this is indicative of the decrease in stability and acidification of the process. The anaerobic BFBR using GAC as support matrix experienced no problems with plug formation and channelling. This is due to the lower biomass production by anaerobic microorganisms than in the aerobic reactors. The TS and VS concentrations were lower than the aerobic concentrations but followed the same trend of decreasing over time, while the TSS and VSS concentrations increased due to decreased HRTs. The anaerobic BFBR was sensitive to dramatic variations in organic loading rates, pH and COD removal efficiencies decreased significantly after any shock loadings. Compared to the activated sludge systems currently being used for the biological treatment of Fischer-Tropsch reaction water at SASOL SynFuels, Secunda, South Africa, a seven-fold increase in OLR and a 55 % reduction in the specific air requirement was achieved using the aerobic BFBRs. The methane produced could also be used as an alternative source of energy. It is, however, evident that the support matrix has a significant influence on reactor performance. Excellent results were achieved using sand and GAC as support matrices in the aerobic and anaerobic BFBRs, respectively. It is thus recommended that future research be conducted on the optimisation of the use of aerobic and anaerobic BFBRs using these support matrices. Based on the results obtained from this study, it can be concluded that both aerobic and anaerobic treatment of a synthetic effluent analogous to the Fischer-Tropsch reaction water as generated by SASOL in the Fischer-Tropsch Synthol process were successful and that the application of fluidised-bed reactors (attached growth systems) could serve as a feasible alternative technology when compared to the current activated sludge treatment systems (suspended growth) currently used.

Abstract:
Acrylic acid and formaldehyde are present in several industrial wastewaters including petrochemical wastes. The objectives of this study were to determine the anaerobic degradability of acrylic acid and formaldehyde in acidogenic and methanogenic systems and anaerobic treatability of petrochemical wastewaters containing acrylic acid and formaldehyde Acetate, propionate, and glucose enrichment cultures were used in serum bottle and chemostat studies. The results showed that the acrylic acid was degraded to propionate and acetate and without acclimation it completely inhibited propionate degradation and partially inhibited acetate degradation. In both the methanogenic and acidogenic chemostats, 98% of the acrylic acid was removed. However, the acidogenic chemostat had a significantly higher acrylic acid loading rate (416 mg/L-d) than the methanogenic chemostat (16.7-66.7 mg/L-d). Even at low acrylic acid loading rates, the propionate utilizers required a long time to acclimate to acrylic acid Formaldehyde showed severe toxicity to the acetate enrichment culture. As low as 10 mg/L of formaldehyde completely inhibited acetate utilization. Formaldehyde was, however, degraded while acetate utilization was inhibited. Degradation of formaldehyde (Initial concentration $\le$30 mg/L) followed Monod model with a rate constant, k, of 0.35-0.46 d$\sp{-1}$. At higher initial concentrations ($\ge$60 mg/L), formaldehyde degradation was inhibited and partial degradation was possible. The initial formaldehyde to biomass ratio, S$\sb0$/X$\sb0$, was useful to predict the degradation potential of high concentrations of formaldehyde in batch systems. The inhibition of formaldehyde degradation in batch systems could be avoided by repeated additions of low concentrations of formaldehyde (up to 30 mg/L). Methanogenic chemostats (14-day retention time) showed degradation of 1110 mg/L of influent formaldehyde with a removal capacity of 164 mg/g VSS-day. The results also showed that the acetate enrichment culture was not acclimated to formaldehyde even after 226 days The acetate enrichment culture, acclimated to acrylic acid and formaldehyde, successfully treated 25% of the 'Wastewater B' from a petrochemical plant containing high concentrations of acrylic acid (1650 mg/L) and formaldehyde (3330 mg/L) and other constituents. The removal efficiency for acetic acid, acrylic acid, formaldehyde, and COD were 99, 99, 99, and 91%, respectively. The unacclimated acetate enrichment culture can also be used to treat 'Wastewater A' containing low concentrations of acrylic acid (240 mg/L) and formaldehyde (30 mg/L).

In this study, pilot-scale Fixed Film Reactor (FFR) and Moving Bed Biofilm Reactor (MBBR) were installed in the field to test if these pretreatments could effectively help promote the biodegradation of a petrochemical industry wastewater in a Powdered Activated Carbon Treatment (PACT) process. Biological agents were first screened in the laboratory using respirometer to determine the type and dosage to be added in the FFR. Through biological activity and pollutant removal efficiency, performance of the biological agents in the FFR was evaluated, and this evaluation will be used in the future to promote the treatment performance, increase the treatment capacity, or reduce the operation cost. Analysis of the raw wastewater from the Ta-She Industrial Wastewater Treatment Plant showed a sliding BOD effect, i.e., the BOD value increased with the dilution ratio. This indicated that there might have refractory compounds in wastewater or that biological degradation was somehow inhibited. Respirometry analysis showed that in the first 20 hours of experiment with dilution ratio less than 5, Specific Oxygen Uptake Rate (SOUR) increased with time with a slight inhibition of the biological degradation was observed. When the dilution ratio was increased to more than 8, this inhibitory effect was not visible. In the continuous operation of the FFR in the field, data indicated that the influent and effluent BOD5 were between 20-45 mg/L and 11-38 mg/L, respectively. The FFR had a better performance when operated under a Hydraulic Retention Time (HRT) of 12 hours than under 22 hours. Removal efficiencies of SS, VSS, SCOD, and BOD5 were 40.8±18.5% (n =14), 40.5±18.5% (n =14), 28.14±8.46 (n =14), and 43.5±12.7% (n =14), respectively. When the MBBR was operated under a total HRT of 35.2 hours, results showed the averaged removal efficiencies of SS, VSS, SCOD, and BOD5 were 45.1± 21.8% (n =12), 44.5± 26.6% (n =12), 44.7±20.9 (n =12), and 53.9±32.1% (n =12), respectively. When the FFR was operated under a HRT of 12 hours with an addition of 5 ppm bioagent B, results showed a significant improvement in the performance, with the averaged removal efficiencies of SS, VSS, SCOD, and BOD5 were increased to 59.7±8.6% (n =5), 63.8±7.8% (n =5), 57.6±14.3 (n =5), and 66.9±17.4% (n =5), respectively. After daily addition of 5 ppm bioagent B in the FFR, the VSS/SS (0.58 ±0.09, n =5) was found to be less than effluent VSS/SS (0.65 ±0.08, n=5). This indicated that the addition of the bioagent could improve degradation of the VSS in the FFR. The ratio of SCOD/TCOD remained almost identical between the influent and the effluent indicated SCOD/TCOD remained almost identical between the influent and the effluent indicated that degradation of soluble COD was improved by the addition of bioagent. Similar trends were observed in the BOD5/SCOD. When bioagent B was added, this ratio from the influent to the effluent was decreased from 0.16 to 0.12, and when bioagent A was added, this ratio was significantly decreased from 0.23 to 0.13. It was found from this study that, FFR had the traditional biological treatment capability and rational removal efficiency, and could be applied after the primary sedimentation tank to reduce the organic loading to the PACT process. When bioagent was added, further degradation of refractory compounds could be expected. Due to its low initial cost, easy operation, and small land requirement, FFR can be applied in combination with other processes to reduce the organic loading to subsequent treatment processes. When operated under a HRT of 12 hours, the averaged TCOD removal efficiency was 31.5 ± 11.1% (n =14). When the bioagent was added, the TCOD removal efficiency could be increased to 57.1 ± 16.7% (n =5).

Abstract:
Constructed Wetlands (CWs) are low-cost and sustainable systems for wastewater treatment. Traditionally they have been used for urban and domestic wastewater treatment, but in the last two decades, the applications for industrial wastewater treatment increased due to the evolution of the technology and the extended research on the field. Nowadays, CWs have been applied to the treatment of different kind of wastewaters as such as refinery and petrochemical industry effluents, food industry effluents including abattoir, dairy, meat, fruit and vegetables processing industries, distillery and winery effluents, pulp and paper, textile, tannery, aquaculture, steel and mixed industrial effluents. In this chapter, the authors present the main types of CWs, explain how they work and the expected performances, and describe the principal applications of CWs for industrial wastewater treatment with particular attention to suspended solids, organic matter and nutrient removal. A review of these applications as well as some case studies will be discussed.
