  • Wastewater treatment for a municipality

    Description of the plant At first, wastewater is pre-treated by a combinated sand and fat trap before further treatment is affected by a special screen. The accruing particles are collected in anti-septic plastic bags to avoid any personal contact because of hygienic reasons. Based on the high varying hydraulic amount of wastewater, an aerated mixing and balancing reactor is ...

  • CH#831 - Municipal Wastewater Treatment Plant

    Introduction The Wastewater Treatment Plant is a rotating biological contactor treatment process preceded by bar screening, grit removal and primary settling. Subsequent to the secondary treatment process, the flow stream enters a chlorine contact tank and then goes to the receiving stream. The program study was started on March 4th. The objectives were a recovery from filamentous infestation, ...

  • Life cycle–based environmental assessment of municipal wastewater treatment plant in India

    The environmental footprint of wastewater treatment plant (WWTP) can be assessed using a life cycle assessment (LCA) approach. Life cycle impacts are computed according to the CML 2 baseline 2000 methodology. An LCA study was carried out for WWTP treating municipal wastewater. Results show that the construction phase contributes to nearly 1% for the impacts when compared to overall life cycle ...

  • Investment and operating costs of municipal wastewater treatment plants in China

    The municipal wastewater treatment will continue to be intensified in China due to the economic development and the poor water quality. Within four years, the number of wastewater treatment plants has doubled. Before 2000, mostly plants without nitrogen and phosphorous removal were built. Since Chinese laws require strict effluent qualities, many plants were built with ...

  • Monitoring and evaluation of removal of pathogens at municipal wastewater treatment plants

    The concentrations and removal of Cryptosporidium, Giardia, and microbial indicators, including somatic coliphages and fecal coliforms were investigated through the wastewater treatment processes at three municipal wastewater treatment plants in Beijing, China. The experimental results showed that the concentrations of Cryptosporidium in untreated wastewater, ...

  • Co-digestion of press liquids of source-sorted municipal organic waste in anaerobic sludge treatment of municipal wastewater treatment plants

    This paper describes a semi-continuous laboratory-scale investigation of a potential co-substrate for mesophilic anaerobic sludge digestion in a municipal wastewater treatment plant. A feed liquid produced from source-sorted municipal organic waste by pretreatment with a screw press was subjected to the investigation. Quantities produced in press trials as well as the composition of the feed ...

  • Benchmarking energy consumption in municipal wastewater treatment plants in Japan

    Reduction of greenhouse gas (GHG) emissions is one of the most important tasks facing municipal WWTPs. Electric power consumption typically accounts for about 90% of the total energy consumption. This study presents a benchmarking analysis of electric power consumption. The specific power consumption (SPC) ranged from 0.44 to 2.07 kWh/m3 for oxidation ditch plants and from 0.30 to 1.89 kWh/m3 for ...

  • Fate of phthalate esters in municipal wastewater treatment plant and their environmental impact

    The fate and distribution of six phthalate esters (PAEs) in a municipal wastewater treatment plant (WWTP) employing an anaerobic/anoxic/oxic (A2/O) process were investigated. The process achieved relatively high removal efficiencies of PAEs in the range 55–97%. It illustrated that biotransformation and sludge-adsorption were major elimination pathways by analyzing the mass balance and flux of ...

  • Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment

    Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these two ...

  • Pyrethroid insecticides in municipal wastewater

    Pyrethroids are widely used insecticides, but there is minimal published information on their presence in municipal wastewater in the United States. Pyrethroids in wastewater from the Sacramento, California area, consisted of permethrin, bifenthrin, cypermethrin, and cyhalothrin with a combined concentration of 200–500 ng/L. Sampling within the wastewater collection system leading to the ...

  • Cost Trends of MBR Systems for Municipal Wastewater Treatment

    Cost estimates were developed for full-scale (1 and 5 MGD) MBR facilities designed to treat municipal wastewater. These estimates included both capital and operational / maintenance (O&M) costs related to the headworks, MBR process (biological process and membrane system), chlorine disinfection and effluent storage. The costs associated with the membrane systems were developed from budgetary cost ...

  • Quantifying Sludge Production in Municipal Treatment Plants

    ABSTRACT This paper addresses the issue of sludge production in plants treating municipal wastewater. The historical understanding and quantification of sludge production in activated sludge systems is reviewed briefly. An important factor is the selection of three parameters used in the estimation of sludge production (and carbonaceous oxygen requirements). These are the yield coefficient ...
