  • 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 ...

  • 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 ...

  • 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 ...

  • Los Angeles County WRRF Embraces Codigestion

    Technology to produce food waste slurry key to project implementation - and helps generators comply with California organics recycling mandates. The Sanitation Districts’ JWPCP in Carson (CA) treats an average of 280 million gallons/day of wastewater. One of the two anaerobic digestion tanks above has been used for codigestion, with the second serving as the control. Photos ...

  • 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 ...

  • 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 ...

  • 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 ...

THE CHALLENGE Prichard AL is a town of about 30.000 people north of Mobile. AL Paul David, the Sewer Board Superintendent, oversees the contract management of two (21 ...

  • 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 ...

  • Municipal Wastewater Pump Station Design Problems and Solutions

    The growth of the Northern Virginia Area around Washington D.C. has resulted in the requirement for numerous new wastewater pumping stations and the upgrade and expansion of existing pump stations. This paper presents practical problems and solutions associated with the following pump station design issues: 1.) Concrete Corrosion Protection, 2.) Corrosion Resistant Materials, 3.) Pump Protection ...

  • Otis, MA municipal wastewater treatment plant information

    Small and rural communities generally find it difficult to assemble the resources to develop a traditional wastewater infrastructure.  Yet, without infrastructure it is difficult to enhance property values and economic development.  Decentralized wastewater treatment systems represent a low cost, low impact and high benefit solution.  Employing modular systems whose processes are ...
