  • 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 ...

  • Treatment of municipal wastewater by membrane bioreactor: a pilot study

    The operational performance of a submerged hollow fibre Membrane Bio-Reactor (MBR) for treatment of municipal wastewater on pilot scale was investigated. The experimental results indicated that the removal efficiency for SS, COD, NH4-N, turbidity, bacterium, iron (Fe2+) and Manganese (Mn2+) was 100%, 94.5%, 98.3%, 99.7%, lg6, 99%, 92.3%, respectively. The water quality of the effluent was quite ...

  • 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 ...

  • 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, ...

  • Integrated Anaerobic and Aerobic Processes for Treatment of Municipal Wastewater

    ABSTRACTIn this study, integrated anaerobic and aerobic treatment processes for municipal wastewater treatment were investigated for its feasibility to replace the existing conventional activated sludge process. Three types of anaerobic systems − anaerobic sludge blanket, anaerobic sequencing batch reactor and anaerobic filter, as the pretreatment step were studies. High solids and organics ...

  • Cellulose recovery from municipal wastewater

    During Aquatech 2015 the Dutch technology developer Brightwork set in the spotlight the recovery of cellulose from waste water. The project Cellulose Assisted Dewatering of Sludge (CADoS) aims at separating cellulose fibres from toilet paper from waste water using finescreening technology. After separation the fibres serve as a filter aid for effective dewatering of biological sludge. The ...

  • 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 ...
