The efficiency of microbial inactivation in water is highly dependent on the type of treatment technology used as well as the characteristics of the water to be treated. Wastewater from poultry slaughterhouses carries a significant number of microorganisms posing threats to humans and the environment in general. Therefore, the treatment of poultry slaughterhouse wastewater requires the use of appropriate purification systems with high removal efficiency for microbial agents. In this study, the performance of an integrated treatment plant with electrolysis, ultrafiltration, and ultraviolet radiation as the principal treatment units was investigated in terms of microbial inactivation from poultry slaughterhouse wastewater. In this case, total microbial number, total coliform bacteria, thermo-tolerant coliform bacteria, pathogenic flora, including salmonella coliphages, spores of sulfite-reducing clostridia, Pseudomonas aeruginosa, and Staphylococcus aureus and Enterococcus were studied. Approximately 63.95% to 99.83% of the microbes were removed by the electrochemical treatment unit as well as a 99.86% to 100% removal efficiency was achieved after the combined treatment. However, Pseudomonas aeruginosa was the only microbial agent detected in the final effluent after the combined treatment. The phenomenon suggests that an upgrade to the treatment plant may be required to achieve 100% removal assurance for Pseudomonas aeruginosa.

Abstract Hydroxypropyl guar gum is considered to be a main component of oilfield fracturing wastewater (OFW). This work is intended to optimize the experimental conditions for the maximum oxidative degradation of hydroxypropyl guar gum by the coagulation and UV/H2O2/ferrioxalate complexes process. Optimal reaction conditions were proposed based on the chemical oxygen demand (COD) removal efficiency and UV_vis spectra analysis. The overall removal efficiency of COD reached 83.8% for a dilution ratio of raw wastewater of 1:2, pH of 4 and FeCl3 loading of 1,000 mg/L in the coagulation process; the dosage of H2O2 (30%,v/v) was 0.6% (v/v) and added in three steps, the n(H2O2)/n(Fe2+) was 2:1, n(Fe2+)/n(C2O42−) was 3:1 and pH was 4 in the UV/H2O2/ferrioxalate complexes process; pH was adjusted to 8.5–9 by NaOH and then cationic polyacrylamide (CPAM) of 2 mg/L was added in the neutralization and flocculation process. The decrease in COD during the coagulation process reduced the required H2O2 dosage and improved efficiency in the subsequent UV/H2O2/ferrioxalate complexes process. Furthermore, COD removal efficiency significantly increased by more than 13.4% with the introduction of oxalate compared with UV/Fenton. The UV_vis spectra analysis results indicated that the coagulation and UV/H2O2/ferrioxalate complexes process could efficiently remove the hydroxypropyl guar gum dissolved in OFW. An optimal combination of these parameters produced treated wastewater that met the GB8978-1996 Integrated Wastewater Discharge Standard level III emission standard.

Water reuse and recycling is gaining momentum as a way to improve the circularity of cities, while recognizing the central role of water within a circular economy (CE) context. However, such interventions often depend on the location of wastewater treatment plants and the treatment technologies installed in their premises, while relying on an expensive piped network to ensure that treated wastewater gets transported from the treatment plant to the point of demand. Thus, the penetration level of treated wastewater as a source of non-potable supply in dense urban environments is limited. This paper focuses on the demonstration of a sewer mining (SM) unit as a source of treated wastewater, as part of a larger and more holistic configuration that examines all three ‘streams’ associated with water in CE: water, energy and materials. The application area is the Athens Plant Nursery, in the (water stressed) city of Athens, Greece. SM technology is in fact a mobile wastewater treatment unit in containers able to extract wastewater from local sewers, treat it directly and reuse at the point of demand even in urban environments with limited space. The unit consists of a membrane bioreactor unit (MBR) and a UV disinfection unit and produces high quality reclaimed water for irrigation and also for aquifer recharge during the winter. Furthermore, a short overview of the integrated nutrient and energy recovery subsystem is presented in order to conceptualise the holistic approach and circularity of the whole configuration. The SM technology demonstrates flexibility, scalability and replicability, which are important characteristics for innovation uptake within the emerging CE context and market.

Reclaimed wastewater reuse for irrigation to crop plants is evaluated in a laboratory-scale experiment to assess growth and water saving potential from natural resources. A prototype laboratory-scale treatment plant was established for this purpose with suspended and attached growth configurations. Chakwal wheat variety was selected to examine growth parameters. The removal of chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) were evaluated to check the quality of treated water. It was found that a suspended growth sequencing batch bioreactor (SGSBBR) achieved 97% ± 2 removal efficiency over a 4 h hydraulic retention time (HRT). For an attached growth sequencing batch bioreactor (AGSBBR) results showed 98% ± 2 removal efficiencies with polyurethane. TN and TP removal efficiency was 58.7 ± 3% and 64 ± 4.8% in SGSBBR, 53 ± 0.17% and 67 ± 2.7% in polyurethane. AGSBBR enhanced performance with AGSBBR may be due to enforced anoxic/aerobic conditions in the inner layers of biofilm formed on biocarriers which facilitate the required metabolic conditions for treating high strength wastewater. Plant growth was visibly greater in SGSBBR treated wastewater than AGSBBR because of less nutrient removal.

The industrial wastewater from a carbon monoxide production unit was treated by physico-chemical processes in order to achieve a quality level appropriate for reuse. In preliminary tests, coagulation/flocculation (CF), sand filtration and activated carbon adsorption were investigated in order to select the materials and the process conditions. Based on the results a combined treatment was proposed: CF followed by down-flow filtration in a combined medium (sand and granular activated carbon). The results obtained in a bench-scale treatment unit showed that the combined treatment removed wastewater turbidity (95%), total suspended solids (97%), volatile suspended solids (81%), chemical oxygen demand (74%) and dissolved organic carbon (65%). Polycyclic aromatic hydrocarbons (PAHs) were removed to non-detectable levels. The residual conductivity of the treated wastewater is a matter of concern, and considering the water characteristics of this industrial process, a reuse scheme was proposed based on on-line monitoring and control of conductivity and partial reuse of the treated wastewater.

Wastewater is an essential reservoir of pathogenic bacteria, which include resistant strains. This study determined the antibiotics resistance pattern of Coliform bacteria isolated from slaughterhouse wastewater in Jega local government. Five different samples of wastewater from different locations of a slaughterhouse were collected using standard sample collection techniques. Coliform bacteria were isolated using the standard microbiological method. The total bacterial count was determined using plate count agar. Suspected coliforms were identified based on morphological and biochemical tests. Antimicrobial susceptibility testing was carried out using the standard disc diffusion method. The highest bacterial count (8.4x102 CFU/ml) was observed from the wastewater collection point, and the lowest bacterial (1.2x102 CFU/ml) count from the slaughtering point. Three Gram-negative bacteria, Escherichia coli, Pseudomonas aeruginosa, and Enterobacter aerogenes, were identified. Escherichia coli was the most frequently isolated in slaughterhouse wastewater 39 (45.8%). Among the antibiotics tested against isolated bacteria, Septrin was the most resistant antibiotics recorded against E. coli and E. aerogenes with 84.61% and 88.89% resistant, respectively. Pseudomonas aeruginosa was found to show higher resistance to Chloramphenicol and Septrin with 84.21% resistance each. The occurrence of antibiotic-resistant bacteria from slaughterhouse wastewater showed the risks associated with antimicrobial drug resistance transferred from food-producing animals to humans. Management concerns, such as local government health officers and community development officers, should increase the sensitization of slaughterhouse workers by organizing conferences or conducting radio talk to educates these slaughterhouse workers on the treatment of slaughterhouse wastewater and health risk associated with antimicrobial-drug resistance transferred from animals to humans.

Anaerobic Sludge Blanket

The Buoyant Filter Bio-Reactor (BFBR) is a novel and very efficient method for the treatment of complex wastewater. Sewage is a complex wastewater containing insoluble COD contributed by fat and proteins. The fat and proteins present in the domestic sewage cause operational problems and underperformance in the Upflow Anaerobic Sludge Blanket Reactor, used now for treating sewage anaerobically. The biogas yield from the BFBR is 0.36 m3/kg COD reduced and the methane content was about 70–80%. Production of methane by anaerobic digestion of organic waste had the benefit of lower energy costs for treatment and is thus environmentally beneficial to the society by providing a clean fuel from renewable feed stocks. The BFBR achieved a COD removal efficiency of 80–90% for an organic loading rate of 4.5 kg/m3/d at a hydraulic retention time of 3.25 hours. The effluent COD was less than 100 mg/l, thus saving on secondary treatment cost. No pretreatment like sedimentation was required for the influent to the BFBR. The BFBR can produce low turbidity effluent as in the activated sludge process (ASP). The land area required for the BFBR treatment plant is less when compared to ASP plant. Hence the problem of scarcity of land for the treatment plant is reduced. The total expenditure for erecting the unit was less than 50% as that of conventional ASP for the same COD removal efficiency including land cost.

Treatment Stage

In 2010, the Mannheim wastewater treatment plant was expanded with an adsorptive treatment stage to remove organic micropollutants (OMPs). Differences in the removal efficiencies of the OMPs investigated were determined over four years of operation by applying different powdered activated carbon (PAC) products and a constant volume-proportional dosing of 10 mg PAC/L. Possible influences on the removal efficiency are discussed here on the basis of the data obtained, exemplified for the analgesic diclofenac. The analyses show that the removal efficiency is influenced significantly by the spectral absorption coefficient (SAC) of the biologically treated wastewater at a wavelength of 254 nm (SAC254). Therefore, in order to ensure the constant treatment performance desired, the dosage of PAC should be adjusted to the measured SAC254 values. Moreover, as the SAC254 reduction correlates with the removal efficiency of OMPs, the additional determination of its reduction allows indirect control of the actual removal performance achieved. The SAC254 reduction can also be used for targeted control of the PAC dosage.

Phosphorus is one of the most important nutrients affecting the eutrophication, so its treatment is the most important thing that must be taken before wastewater is dumped into water bodies. This paper presents a study on phosphorous removal by adsorption with oven-dried-alum-sludge (ODAS) that was collected from Baqubah treatment plant (Iraq) and preheat at 105 ° C, cool down at room temperature, and crushed into small particles of (0.8-5) mm. The effect of ODAS studied with doses of 1.25-20 g/l and found that the higher the dose of adsorbent, the higher the percentage of phosphorous removal. Contact time also studied its effect on phosphorous removal and found that it has a clear effect on the adsorption process, as the percentage of phosphorous removal efficiency increased with increasing contact time. The optimum dosage of ODAS was 10 g/l and contact time 180 min with phosphorous removal efficiency (98%, 99%, 97%, and 97%) for initial concentration of (5, 10, 15, and 20) mg/l of phosphorus.
