The use of membrane separation technology, such as ultrafiltration (UF) and subsequent reverse osmosis (RO), for purifying different types of low-contaminated wash water of carrots (COD = 1,314 mg/l) and wash water of different kinds of vegetables (COD = 2,280 mg/l) was investigated on a pilot scale to determine its suitability for reuse in the process. In both membrane processes, UF and RO, the permeate flux first decreased with increasing fouling (deposition of organic and inorganic substances on the membrane surface and in its pores). After that the membrane permeability (permeate flux) and selectivity (rejection of COD) remained constant on a stable level in spite of a concentration with a volumetric concentration factor of up to 39. The tests showed that water can be obtained with a quality complying with the German regulations by applying a process combination of UF and RO. It was found that the membranes gave a 5-log reduction for total bacteria, and no coliform bacteria were present in the permeate after RO. Using UF and RO, part of the wastewater can be recovered for reuse in the process if drinking water is used for the last step of vegetable washing.

Annotation:
Constructed wetlands are emerging as a serious challenge to conventional wastewater treatment because of lower construction and operating costs, less requirement for trained personnel, more flexibility, and lower susceptibility to variations in waste loading rates. Water quality improvements can be achieved by removal of plant nutrients, such as N and P, organics (natural and manmade) as well as inorganic contaminants. Wetland treatment is now advocated by regulatory agencies and has been determined as the technology of choice by municipalities and industries required to meet stringent discharge regulations. These same regulations have not usually been imposed on the agricultural community, but deteriorating water sources will likely change this regulatory anomaly. Use of this technology in treating agricultural wastewater is still in its infancy with few, although rapidly expanding, applications. This paper aims to highlight different aspects of wetland treatment by exploring its use for the treatment of agricultural run-off as well as wastewater from the agri-food industry. It is concluded that natural wetlands will be quite limited in absorbing agricultural wastewater while constructed wetlands can be designed for optimum pollutant removal. Key words: Constructed wetlands, wastewater treatment, agriculture, food processing, nutrient removal, nitrogen, phosphorus, organics

The treatment of agroindustrial wastewaters gives the possibility of noxious pollutant removal which otherwise would deteriorate the ecosystem even more. The construction and start-up of Integrated Systems for the treatment of such wastes allow the reuse of the treated effluents, with the consequent production of useful by-products. Biological processes for the adequate treatment of 300 m3/day of mixed animal and human wastewaters allow also the production of 1200 m3/day of biogas as an energy supplier and a source of CO2 for microalgae culture in a High Rate Algal Pond. On the other hand, it can be possible to recover the digested sludge as biofertilizer and low grade water useful for crop irrigation. The proposed Integrated System also provides the recovery of 8.3 g/m2/d of algal biomass suitable for animal consumption and the removal of an important amount of noxious pollutants with an average efficiency of 80–98% (COD basis).

The Greater Tel-Aviv (Dan Region) urban area is composed of seven municipalities producing close to 100 million cubic meters per year (mcmy) of wastewaters, serving a population equivalent of over 1.7 millions. The Dan Region Association of Towns for Sewerage serves the largest population, commercial and tourism center of Israel as well as an important part of its industry. The flow of wastewater in the region is expected to reach some 150 mcmy by the end of this decade due to its intensive growth. Due to the perennial and severe shortage of water, Israel has adopted a national policy of maximizing wastewater reuse, aimed principally at agricultural irrigation of crops without any restrictions (including fruits and vegetables eaten uncooked). The quality requirements for the reclaimed wastewater are quite stringent, due to the fact that a large proportion of the agricultural produce is intended for export to foreign countries. The Dan Region - Third Line scheme is an example of a holistic approach to urban sewerage system integrated with reclamation and agricultural reuse, within an overall policy-making, engineering design, operation, monitoring, surveillance, management, administration and legal framework. It has a combined health, environmental and economical benefit to the urban communities and critical economic and livelihood benefit to the rural community.

Annotation:
Areas in relatively dry climates often have water shortages and there is competition between municipal and agricultural (irrigation) water use. The problem can be alleviated by using the water twice, first for the cities and then for agriculture after the municipal wastewater has been properly treated. There are now two sets of water quality standards for irrigation with wastewater: a stringent set for developed countries, and a less stringent set for developing countries. Also, more and more cities will have to use their wastewater internally for irrigation of parks, etc., and even for drinking. The latter requires advanced wastewater treatment. Part of this treatment can be supplied inexpensively by a groundwater recharge and recovery system, which also provides storage and enhances the aesthetics of direct potable reuse of wastewater by breaking the pipe-to-pipe connection. The renovated water from a recharge or “soil-aquifer treatment” system generally can be used as such for unrestricted irrigation, but potable use requires additional treatment.

Abstract. Harsh environment, severe aridity, and climate change create chronic water shortages in the Middle East. Technical challenges, socio-economic factors, and competing uses of water have escalated the difficulties in water planning at national and institutional levels. This research identifies opportunities and challenges associated with wastewater treatment systems and the potential for wastewater reuse in the West Bank, Tunisia, and Qatar through the following objectives: (1) identify the factors associated with successful and unsuccessful reuse schemes, (2) compare treated wastewater quality with end use application of treated wastewater, and (3) identify the governance and social challenges preventing the use of treated wastewater, specifically in agricultural applications. Water quality analyses and consultations with farmers, local stakeholders, and water and agriculture experts were conducted. Opportunities and challenges for treated wastewater reuse in agriculture are identified as the proximity of the treatment facility to agricultural areas, water quality, and motivation of farmers. With proper maintenance and appropriate monitoring, the modest (natural) treatment facilities in the West Bank and secondary treatment technologies in Tunisia are capable of producing effluent safe for use in production of certain agricultural products; however, in Qatar, despite massive investments in producing high-quality treated wastewater using advanced treatment technologies, there is little demand. Water policies, laws and acts, and action plans are urgently needed to be coupled and integrated for implementation. Keywords: Arid lands, Food security, MENA, Wastewater treatment, Water reuse.

The paper summarizes the history and the use of the rhizosphere for wastewater treat-ment. This technology assures high level of pollutant removal and presents an ecological cha-racter. Most systems around the world are still primarily used to treat municipal and domestic wastewaters but treatment of many types of industrial and agricultural wastewaters, storm wa-ter runoff and landfill leachate has recently become common. There are several types of con-structed wetlands (rhizosphere systems), and they can be classified according different crite-ria: the water level, the direction of the flow, the type of vegetation.

Annotation:
The effect of irrigation with treated municipal wastewater on the agricultural income from cotton and corn crops was studied by a three-year field experiment (1995-1997), carried out within the wastewater treatment plant (WWTP) of the city of Larissa, central Greece. The experimental design for both crops was randomised complete blocks with five treatments (M- control-irrigation with fresh water, W-irrigation with wastewater and no mineral fertilization, MF- irrigation with fresh water and complete mineral fertilization, WSF- irrigation with wastewater and reduced mineral fertilization, WTF- irrigation with wastewater and complete mineral fertilization). Each treatment was replicated four times. The agricultural income was assessed using the yield of the crops and the economic data of the area. The results showed that in the case of corn, the treatment WTF gave the highest agricultural income. The treatments W and WSF gave higher agricultural income compared to the control but was not significantly different compared to the treatment MF. In the case of cotton, all the treatments included wastewater use, increased significantly the agricultural income in comparison to the control, but at similar level as the treatment MF did. From the data of this study, it is concluded that treated wastewater can be used for irrigation of corn and cotton, saving fresh water and mineral fertilizers and obtaining the same or better economic results.

Rapid urbanization and population growth have represented a great challenge to water resources management, since wastewater generated in urban areas forms a non-conventional source, wastewater reuse is being recognized as a sustainable water management approach. This study focuses on with the potential and practibility of implementing wastewater reuse techniques in Izmir region, especially with the aim to use treated wastewater and nutrient for agriculture. To this end, qualititative and quantitative agricultural water demand were considered. This thesis introduces a wastewater reuse planning model and optimization method with an emphasis on the wastewater treatment technology used as well as the agricultural demand in the area of the study. The model was developed with considerations over water quality, wastewater treatment and discharge. The objective of the model is to upgrade existing wastewater treatment plants or to design new treatment plants in regard to reuse wastewater in agriculture. The model is also capable of comparing treatment technologies from the point of design and cost. Three case studies were represented so as to demonstrate the modeling process and optimization studies for agricultural irrigation.

Annotation:
Bioflocculation of Wastewater Treatment Pond Suspended Solids Louis Lefebvre Wastewater treatment lagoons and high rate algae ponds (HRAPs) can provide cost effective wastewater treatment, but they commonly have high effluent concentrations of total suspended solids (TSS). In this thesis algae pond effluent was treated in a beaker testing apparatus (mixed and aerated) with various mixtures of activated sludge and primary effluent simulating differing activated sludge aeration basin compositions then was allowed to settle to assess settleability. Conventionally, microalgal suspended solids are removed by chemical coagulation followed by separation methods that often have a high cost relative to the low cost lagoon or HRAP system where the solids were produced. This separation step is often cost prohibitive or operationally complex for municipalities or too energy intensive for application in algae biofuels production. This research investigates using a small amount of activated sludge material to promote bioflocculation of algae in pond effluent. It was hoped that the findings may demonstrate a path for municipalities to keep their lagoons, while increasing capacity and improving treatment without excessive cost or complexity. Experiments were conducted on microalgae samples from a pilot-scale HRAP and activated sludge and primary effluent samples from a local municipal wastewater plant. The samples were placed in a mixing apparatus and allowed to settle for a given period of time, after which TSS was analyzed for settleability. The experiments investigated the effect of various lab-scale activated sludge reactor operational schemes by varying the volumes (and masses) of activated sludge, algae-rich water, and activated sludge in the beaker. Results in the sorption test (tests with only activated sludge and algae-rich water) demonstrated algae pond effluent treated with activated sludge concentrations of 3000 mg/L or greater produced final effluent TSS concentrations near discharge requirements (40-50 mg/L) with only 30 minutes of settling and without addition of primary effluent. However, such high activated sludge concentrations are not feasible at full scale. Furthermore, beakers with activated sludge concentrations greater than 3000 mg/L reduced TSS concentrations by more than 150 mg/L with only 30 minutes of settling and without addition of primary effluent. Results in the aerobic beaker tests (tests with primary effluent, activated sludge, and algae-rich water) showed greater than 200 mg/L TSS removal and final effluent TSS concentration less than 30 mg/L was achieved using activated sludge to primary effluent volumetric ratios of 1:1 and greater which corresponded to activated sludge concentrations of 730 mg/L and greater. Activated sludge concentrations of 730 mg/L may not be feasible at full scale. This report shows that a PETRO-like process is effective in lowering wastewater pond suspended solids, however not to typical discharge standards.

Annotation:
Treating elevated nutrients, suspended solids, oxygen demanding materials, heavy metals and chemical fertilizers and pesticides in agricultural wastewaters is necessary to protect surface and ground waters. Constructed wetlands (CWs) are an increasingly important technology to remediate wastewaters and reduce negative impacts on water quality in agricultural settings. Treatment of high strength effluents typical of agricultural operations results in the production of methane (CH4), a potent greenhouse trace gas. The objective of this study was to evaluate CH4 emissions from two subsurface flow (SSF) CWs (223 m2 each) treating dairy wastewater. The CWs were implemented at the University of Vermont Paul Miller Dairy Farm in 2003 as an alternative nutrient management approach for treating mixed dairy farm effluent (barnyard runoff and milk parlor waste) in a cold, northern climate. In 2006, static collars were installed throughout the inlet, mid and outlet zones of two CWs (aerated (CW1) and a non-aerated (CW2)) connected in-series, and gas samples were collected via non-steady state chambers (19.75 L) over a nine-month period (Feb-Oct 2007). Methane flux densities were variable throughout the nine-month study period, ranging from 0.026 to 339 and 0.008 to 165 mg m-2 h-1 in CW1 and CW2, respectively. The average daily CH4 flux of CW1 and CW2 were 1475 and 552 mg m-2 d-1, respectively. Average CH4 flux of CW1 was nearly threefold greater than that of CW2 (p = .0387) across all three seasons. The in-series design may have confounded differences in CH4 flux between CWs by limiting differences in dissolved oxygen and by accentuating differences in carbon loading. Methane flux densities revealed strong spatial and seasonal variation within CWs. Emissions generally decreased from inlet to outlet in both CWs. Average CW1 CH4 flux of the inlet zone was nearly threefold greater than mid zone and over tenfold greater than flux at the outlet, while fluxes for CW2 zones were not statistically different. Methane flux of CW1 was nearly fifteen fold greater than CW2 during the fall, representing the only season during which flux was statistically different (p = .0082) between CWs. Fluxes differed significantly between seasons for both CW1 (p = .0034) and CW2 (p = .0002). CH4 emissions were greatest during the spring season in both CWs, attributed to a consistently high water table observed during this season. Vegetation was excluded from chambers during GHG monitoring, and considering that the presence of vascular plants is an important factor influencing CH4 flux, the potential CH4 emissions reported in our study could be greatly underestimated. However, our reported average CH4 fluxes are comparable to published data from SSF dairy treatment CWs. We estimate average and maximum daily emissions from the entire CW system (892 m2) at approximately 1.11 and 6.33 kg CH4 d-1, respectively, yielding an annual average and maximum flux of 8.51 and 48.5 MtCO2-e y-1, respectively.

A partir do trabalho de campo feito na região agrícola de Nova Friburgo, RJ, determinou-se que o pesticida Paraquat é altamente usado. Investigou-se o processo de adsorção com carvão ativado e carvão vegetal deste pesticida em solução aquosa, como uma alternativa para o tratamento de águas residuarias da região. Foi utilizado um resíduo de carvão vegetal, denominado carvão A; e dois carvões ativados comerciais de procedências distintas, denominados respectivamente de carvão B (Brasil) e carvão C (EUA). Realizou-se uma oxidação química com HNO3 do carvão brasileiro, sendo o carvão assim tratado denominado carvão B1. Os estudos de adsorção foram precedidos de um estudo de caracterização dos carvões utilizados, através de microscopia eletrônica de varredura (MEV) e espectroscopia de dispersão de raios X (EDS), para a sua caracterização morfológica. Da isoterma de adsorção de nitrogênio a 77 K, obtiveram-se dados do volume de microporos, área superficial e distribuição de tamanhos dos poros. Espectros de FT-IR detectaram a presença de grupos funcionais nas superfícies e medições de potencial zeta permitiram a determinação do ponto isoelétrico para cada carvão estudado. No processo de adsorção em batelada foram avaliados os efeitos do pH e do tempo para se alcançar o equilíbrio. Foram levantadas experimentalmente isotermas de adsorção para os quatro tipos de carvão. Os carvões ativados B, B1 e C se ajustaram satisfatoriamente ao modelo de isoterma de Freundlich. Estas isotermas forneceram informação a respeito das capacidades de carregamento desses carvões. No estudo da cinética de adsorção, foram avaliadas as correlações dos modelos de pseudo-primeira ordem e pseudo-segunda ordem com os dados experimentais obtidos. Finalmente, os testes preliminares em coluna, em regime contínuo, permitiram a obtenção da curva de carregamento (curva de breakthrough) para o carvão ativado comercial de fabricação brasileira.
According to the work performed in the agricultural region in Nova Friburgo, RJ; it was determined that the Paraquat Pesticide is highly used. There have investigated the adsorption process with activated carbon and vegetal charcoal for pesticide treatment in aqueous solution, this will an alternative for the wastewater treatment in this region. The experimental study was conducted for a vegetal charcoal and two kinds of porous carbonaceous materials. The first of those was a charcoal made of Eucalyptus spp. wood shavings (carbon A). The second was Brazilian activated carbon (carbon B) made of coconut shell. The third material was an American coconut shell activated carbon (carbon C). The Brazilian activated carbon was further submitted to chemical modification treatment procedure with HNO3 (carbon B1). The tests of adsorption were preceded by study of characterization of the used carbons, through techniques such as scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), for its morphologic characterization. The nitrogen adsorption isotherm at 77 K, obtained data of micropore volume, superficial area and poro size distribution. Besides, the FT-IR spectroscopy detected the surfaces functional groups and the Zeta Potential Zeta determinate of the isoelectric point for each carbon. The main parameters influencing adsorption treatment process, pH and equilibrium time have been examined. There have been experimentally made adsorption isotherms for the four types of carbons, which for the carbons (B, B1 and C) adjust to the Freundlich isotherm model. The uptakes capacities information of carbons was originated by these isotherms. The pseudo-first order model and pseudo-second order model was used for evaluated the kinetic data experimental in this process. Finally, the preliminary tests in column had given a vision about of the continue adsorption and the breakthrough curve formation.

Användandet av obehandlat avloppsvatten inom jordbruket är en växande företeelse i många delar av världen. Speciellt i vattenfattiga områden där avloppsvattnet ses som en värdefull och pålitlig resurs. Det höga näringsinnehållet minskar behovet av konstgödsel och detta ökar böndernas inkomster. Men med användandet av avloppsvattnet följer vissa hälsorisker. Bland annat har man sett en högre förekomst av inälvsmaskar hos bönder som använder orenat avloppsvatten jämfört med de som använder rent vatten. Den här vattenkvalitetstudien har utförts längs floden Musi i Andhra Pradesh, Indien. Musi rinner igenom staden Hyderabad och mycket av stadens avloppsvatten dumpas i floden. Nedströms Hyderabad används detta vatten för bevattning. Längs med floden är dammar byggda, för att avleda vattnet i bevattningskanaler. Reservoirer bildas då flödeshastigheten minskar. Studieområdet sträcker sig från Hyderabad och 28.7 km nedströms. Hypotesen var att reservoirerna fungerar som biodammar och syftet var att kvantifiera dammarnas inverkan på vattenkvaliteten och utvärdera dess lämplighet utifrån ett hälso- och jordbruksperspektiv. Inom studieområdet är reningen med avseende på BOD, Nematoder och E coli 86,9%, 99,9% respektive 99,9%. Trots att reningen är så hög överstiger Nematod- och E coli-koncentrationerna Världshälsoorganisationens riktlinjer och utgör en hälsorisk för bönder och konsumenter. Syre- och salthalt ökar nedströms och den höga salthalten kan ha negativ inverkan på jordbrukets avkastning. Genom att titta på reningsmönster och förändring av olika vattenkvalitetsparametrar är en av slutsatserna av detta arbete att reningen i dammarna motsvarar den rening som sker i de anaeroba bassängerna i ett biodammsystem.


The use of untreated domestic sewage in agriculture is a growing practice in many parts of the world. It is being looked upon as a valuable and reliable resource in water scarce communities. Wastewater is usually rich in nutrients and the use results in high yields without the need for artificial fertilisers. But with the use of untreated wastewater follows a number of associated health risks, e.g. a higher prevalence of helminth infections has been seen among wastewater users compared to non-users. This water quality study was performed along the River Musi in Andhra Pradesh, India. The Musi River flows through the city of Hyderabad carrying the most of the town’s wastewater. Downstream of Hyderabad the wastewater is used by farmers for irrigation. Along the river weirs are constructed which diverts the irrigation water into canals and reservoirs are formed where the flow velocity slows down. The study area stretches from Hyderabad and 28.7 km downstream. The hypothesis was that the existing irrigation infrastructure acts like Wastewater Stabilisation Ponds and the aim was to quantify the impact of the weirs on water quality and to evaluate the irrigation water quality in reference to associated health risks and agricultural suitability. Within the study area the BOD, E coli and Nematode removals were 86.9%, 99.9% and 99.9% respectively. Despite the high removal the E coli and Nematodes, the concentrations exceed WHO guidelines for unrestricted and restricted irrigation, and there exists an excess risk of intestinal nematode- and enteric infections for farmers. Dissolved oxygen and salinity increases downstream and due to the high salinity farmers could experience reduced crop yields. By looking at removal patterns, and the change in water quality parameters, the conclusion can be made that the reservoirs act like anaerobic ponds in a Wastewater Stabilisation Pond system.

Annotation:
AbstractThis chapter’s target is to accentuate on the benefits for the social-economic development, resulting from the wastewater governance. The wastewater treatment is the process of extraction of extra-resources, namely: residual biogas, used for heat and electricity; sand used in the construction; sludge and purified water, discharged into hydro-basins. Simultaneously, attention should be paid of the environmental challenges in relation to the circular economy. The sludge use should become a national policy with a direct governmental engagement, having in view that wastewater treatment plants and wastewater safety are strategic guidelines. Statistical information was used by Eurostat and the Ministry of Agriculture and Food and Forestry (MAFF)’s Agristatistics Department (2020). A brief literature review of publications on the topic is made at the outset. Thereafter, more light is placed on the regulatory framework in the EU and Bulgaria. The analysis continues with the situation so far, based on existing statistics on the quantities of sludge received and its utilization in agriculture in the European countries and in Bulgaria. Dependence and sludge effect on grain yield are determined on the basis of regression analysis.
