Texto completoENGLISH ABSTRACT: Urine contains up to 80% of nitrogen, 50 % of phosphates and 90 % of potassium of the total load in domestic wastewater but makes up less than 1% of the total volume (Larsen et al., 1996). The source separation and separate treatment of this concentrated waste stream can have various downstream advantages on wastewater infrastructure and treated effluent quality. The handling of undiluted source separated urine however poses various challenges from the origin onward. The urine has to be transported to a point of discharge and ultimately has to be treated in order to remove the high loads of organics and nutrients. Wilsenach (2006) proposed onsite treatment of source separated urine in a sequencing batch reactor before discharging it into the sewer system. This study focused on the treatment of urine in a sequencing batch reactor (SBR) primarily for removal of nitrogen through biological nitrification-denitrification. The aim of the study was to determine nitrification and denitrification kinetics of undiluted urine as well as quantification of the stoichiometric reactions. A further objective was to develop a mathematical model for nitrification and denitrification of urine using experimental data from the SBR. The SBR was operated in 24 hour cycles consisting of an anoxic denitrification phase and an aerobic nitrification phase. The sludge age and hydraulic retention time was maintained at 20 days. pH was controlled through influent urine during volume exchanges. Undiluted urine for the study was obtained from a source separation system at an office at the CSIR campus in Stellenbosch. Conditions in the reactor were monitored by online temperature, pH and ORP probes. The OUR of the system was also measured online. One of the main challenges in the biological treatment of undiluted urine was the inhibiting effect thereof on nitrification rate. The anoxic mass fraction was therefore limited to 17 % in order to allow longer aerobic phases and compensate for the slow nitrification rates. Volume exchanges were also limited to 5% of the reactor volume in order to maintain pH within optimal range. Samples from the reactor were analysed for TKN, FSA-N, nitrite-N, nitrate-N and COD. From the analytical results it was concluded that ammonia oxidising organisms and nitrite oxidising organism were inhibited as significant concentrations of ammonia-N and nitrite-N were present in the effluent. It was also concluded that nitrite oxidising organisms were more severely inhibited than ammonia oxidising organisms as nitrate-N was present in very low concentrations in the effluent and in some instances not present at all. Ultimately the experimental system was capable of converting 66% of FSA-N to nitrite- N/nitrate-N of which 44% was converted to nitrogen gas. On average 48% of COD was removed. A mathematical model was developed in spreadsheet form using a time step integration method. The model was calibrated with measured online data from the SBR and evaluated by comparing the output with analytical results. Biomass in the model was devised into three groups, namely heterotrophic organisms, autotrophic ammonia oxidisers (AAO) and autotrophic nitrite oxidisers (ANO). It was found that biomass fractionation into these three groups of 40% heterotrophs, 30% AAO and 30% ANO produced best results. The model was capable of reproducing the general trends of changes in substrate for the various organism groups as well as OUR. The accuracy of the results however varies and nearexact results were not always achievable. The model has some imperfections and limitations but provides a basis for future work.

Texto completoRemoval of NH4+-N, NO3--N, and COD from the influent was studied in all three years. Irrespective of flow rate or year, the system removed 62~84%, 96~99%, and 6~67% of TKN, NH4+-N, and COD, respectively, from the influent. Under 0.19 m3 m-2 d-1 flow rate, vegetated systems removed slightly more of these constituents from the influent, than did bare-soil lysimeters. Organic degradation mainly occurred in the top 0.1 m soil depth. Degradation of organic and inorganic influent nitrogen increased NO3--N levels in the effluent. Only minimal increases in soil-N levels and N2O emissions occurred with increasing application rates. The nitrogen mass balance accounted for 85∼98% (2003) and 67∼96% (2004) of input nitrogen (through leaching, soil retention, and N2O emissions), the remaining portion being attributable to vegetative effects and volatilization of non-N2O nitrogenous gases. The under established vegetation on the lysimeters reduced nitrogen leaching through soil, being 6% (2003) and 60% (2004) more effective than bare soil.
Effluent water quality improved with decreasing levels of heavy metals. Compared to influent levels, in vegetated lysimeters, under all flow rates, mean effluent As, Cd, Cu, Ni, Pb, and Zn levels had dropped by 58%, 9%, 3%, 37%, 63%, and 52% in 2003, and by 20%, 63%, 5%, 23%, 18%, 57%, and 79% for As, Cd, Cr, Cu, Ni, Pb, and Zn, in 2004. In both years, similar decreases in heavy metal levels occurred in the bare soil lysimeters. Across all flow rates and influent concentrations, soil heavy metal levels increased. In 2004, even low heavy metal content influent further increased (6∼179%) their accumulation in soil. As inputs of heavy metals to the soil increased with the increase in application rates, their associated times to reach maximum permissible limits also decreased.
LEACHN simulation of NO3--N in leachate arising from wastewater application, showed lowered levels with increasing flow rates, due to enhanced denitrification in the resulting anoxic upper soil zones. The simulation under continuous wastewater application at different range of nitrogen concentrations (low, medium, high) showed an increase of NO 3--N levels in the leachate with increasing N-levels. For all flow rates, and under tropical or humid conditions, the effluent NO 3--N levels remained below permissible limits for the low-N content wastewater applications. Intermittent applications, under all wastewater N-contents and flow rates, reduced NO3--N levels in the leachate by 51∼89% compared to continuous wastewater application, and permissible limits were not exceeded. Hence, wastewater with high levels of nitrogenous compounds, as occurs in most developing countries, could be treated by land under an intermittent application pattern, allowing a considerable reduction in nitrate pollution.

Texto completoWastewater treatment methods have always gravitated towards the use of biological methods for the treatment of domestic grey water. This has been proven to offer a series of advantages such as the reduction of pollution attributed to the use of synthetic chemicals; therefore, this decreases the requirement of further costly post primary treatment methods. Although such biological methods have been used for decades, their efficiency and sustainability has always been challenged by inhibitory toxicants which renders the systems redundant when these toxins are prevalent in high concentrations, culminating in the deactivation of biomass which facilitates the treatment. In most instances, this biomass is anaerobic sludge. Hence, the proposal to utilize biofilms which are ubiquitous and selfsustaining in nature. The use of engineered biofilms in wastewater treatment and their behaviour has been studied extensively, with current research studies focusing on reducing plant footprint, energy intensity and minimal usage of supplementary synthetic chemicals. An example of such processes include traditional nitrification and denitrification systems, which are currently developed as simultaneous nitrification and aerobic denitrification systems, i.e. in a single stage system, from the historical two stage systems. However, there is limited literature on biofilm robustness against a potpourri of toxicants commonly found in wastewater; particularly for total nitrogen removal systems such as simultaneous nitrification and denitrification (SND). This study was undertaken (aim) to assess the ability of biosurfactant producing biofilms in the removal of total nitrogen in the presence of toxicants, i.e. heavy metals and phenol, as biosurfactants have been proven to facilitate better mass transfer for pollutant mitigation. Unlike in conventional studies, the assessment of biosurfactant producers in total nitrogen removal was assessed in both planktonic and biofilm state. Since biofilms are known to have increased tolerance to toxic environmental conditions, they were developed thus engineered using microorganisms isolated from various sources, mainly waste material including wastewater as suggested in literature reviewed, to harness microorganisms’ possessing specified traits that can be developed when organisms are growing under strenuous environments whereby they are tolerant to toxic compounds. The assessment of these engineered biofilms involved the development from individual microorganisms to form biofilms in 1L batch reactors where the isolated microorganisms were grown in basal media containing immobilisation surfaces. The assessment of the total nitrogen efficiency was conducted using Erlenmeyer flasks (500mL) in a shaker incubator, with the biofilm TN removal efficiency being assessed in batch systems to ascertain simultaneous nitrification and denitrification rates even in the presence of heavy metals (Cu2+, Zn2+) and C6H5OH. Ambient temperature and dissolved oxygen conditions were kept constant throughout the duration of biofilm development with microorganisms (initially n = 20) being isolated for the initiation of biosurfactant studies which included screening. Results indicated that the engineered biofilms, constituted by biosurfactant producing organisms (n = 9), were consisiting of bacteria (97.19%), Protozoa (2.81%) and Archaea (0.1%) as identified using metagenomics methods. Some of the biosurfactant produced had the following functional group characteristics as determined by FTIR: -CH3-CH2, deformed NH, -CH3 amide bond, C-O, C=O, O-C-O of carboxylic acids, and C-O-C of polysaccharides. Other selected microorganisms (n = 5) tolerated maximum concentrations of the selected toxicants (Cu2+, Zn2+ and C6H5OH) of 2400 mg/L, 1800 mg/L and 850 mg/L, respectively. Enzyme analysis of the total nitrogen removal experiments indicated a higher nitrogen removal rate to be the Alcanigene sp. at 180 mg/L/h.

Resumo: No presente trabalho de pesquisa foi estudada uma alternativa de união de processos anaeróbios e aeróbios sob a forma de um reator compartimentado anaeróbio/aeróbio, no tratamento de esgoto sanitário. O reator era composto por quatro câmaras seqüenciais, sendo as três primeiras anaeróbias e a última aeróbia, totalizando um volume aproximado de 2,5 m3. O Iodo gerado pelo reator foi separado em um decantador laminar e recirculado à quarta câmara. O reator, localizado em uma E.T.E. da cidade de Limeira, SP, foi operado durante um período de 444 dias, divido em cinco fases, com tempo de detenção hidráulica (TDH) total variando de 7 a 16 horas, alimentado com esgoto sanitário que havia recebido tratamento preliminar. As cinco fases de operação corresponderam a 10, 16, 12, 8 e 7 horas de TDH. Os valores de pH ao longo de todas as câmaras e decantador, variaram entre 5,7 e 8,3 e o valor médio foi de 6,8, não sendo necessário correção e pH durante o período de estudo. Os melhores valores de remoção de 0805 foram obtidos na Fase 4 (TDH=8 horas), 56,9 a 95,7%. Contudo o teste estatístico de comparação de médias de duas amostras, verificou não. haver diferença significativa entre as fases, exceto Fase 2, ao nível de P=O,05. O desempenho do reator quanto a remoção de DQOtotal e SST foi semelhante ao obtido para 0805, com valores de 31,4 a 95,6 e 21,0 a 97,3%, respectivamente, o mesmo ocorrendo para o teste estatístico realizado. Os valores encontrados para oxigênio dissolvido no interior da câmara 4 (aeróbia) foram satisfatórios na maior parte do tempo, de acordo com os valores citados na literatura, alcançando valor máximo de 4,70 e mínimo de O mg 02.L-1. A presença do decantador laminar foi importante na remoção de sólidos provenientes do reator. Após o 1070 dia de operação, o Iodo de recirculação apresentou uma sedimentabilidade de boa a ótima. A configuração do sistema em estudo, promove adequado tratamento do efluente aplicado aliado a uma produção de Iodo aeróbio de fácil gerenciamento
Abstract: The present research aimed to study an alternative route for union of aerobic and anaerobic processes, through the use of a baffled reactor, treating sanitary wastewater. The reactor is composed of four sequential chambers, being the first tree anaerobic chambers and the last one aerobic, composing a total volume of approximately 2.5 m3. The sludge generated in the reactor is separated in a laminar sedimentation tank and recycled into the forth chamber. The reactor - placed in a wastewater treating plan of Limeira city, S. P., 8razil -operated in a period of 444 days. This period was divided in five phases, with hydraulic detention times (HOT) varying from 7 to 16 hours. The reactor was fed with sanitary wastewater which had already suffered a preliminary treatment. The five phases of operation corresponded to 10, 16, 12,8 e 7 hours of HOT, respectively. The pH values in all chambers and in the sedimentation tank, varied between 5,7 e 8,3, with a mean value of 6,8; the correction of pH values was not necessary during all periods. The best value of 8005 removal was attained in the Phase 4 (HOT=8 hours), 56,9 to 95,7%. However, the statistic comparison of the means .of two samples showed that there was no significant difference between the phases, except in Phase 2, with P=0,05. The reactor performance, in relation to COOtotal removal and TSS, was similar to that obtained for the 8005, with values of 31,4 to 95,6 and 21,0 to 97,3%, respectively. The same occurred in the statistic test. In chamber 4, the oxygen dissolved values were satisfactory in most of the periods, reaching the maximum of 4,7 and of 0,0 mg 02.L-1. The laminar sedimentation tank was important for removal of solids produced in the sedimentation tank. After the 10ih operation day, the recycled sludge presented a sedimentation capability classified between good and very good. Thus, It is possible to affirm that the baffled reactor configuration of the present work promotes an useful effluent treatment, employed to the production of an aerobic sludge with easy management
