  • 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 ...

  • Treatment of unpleasant odors in municipal wastewater treatment plants

    The purpose of this paper to present a case study on how to address the odor problem from secondary sources within a municipal wastewater treatment plant (WWTP) by first identifying the locations of the problem and second by evaluating alternative treatment technologies. The WWTP of Chania is a typical 100,000 equivalent inhabitants-facility in a warm semi-arid environment which is located close ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Multi-stage constructed wetland systems for municipal wastewater treatment

    In the present paper the detailed design and performances of two municipal wastewater treatment plants, a four-stage constructed wetlands (CW) system located in the city of Dicomano (about 3,500 inhabitants) in Italy, and a three-stage CW system for the village of Chorfech (about 500 inhabitants) in Tunisia, are presented. The obtained results demonstrate that multi-stage CWs provide an ...

  • Performance of a biofilter system with agave fiber filter media for municipal wastewater treatment

    Agave plants grow in semi-arid regions and are used for mescal production. However, agave fiber by-products are considered waste materials. Thus, we tested agave fiber as a filter media and biofilm material carrier for removing pollutants from municipal wastewater. Three laboratory-scale biofiltration reactors were used in two trials with five hydraulic loading rates (HLRs = 0.27, 0.54, ...

  • Reconsidering rotating biological contactors as an option for municipal wastewater treatment

    There are many domestic wastewater treatment processes in use today. Generally, they are all biological systems and they may be broadly categorized as either fixed film processes or suspended growth processes. During the 1970s and early 1980s, the rotating biological contactor process (RBC), a particularly efficient fixed film process, became popular. However, the primary manufacturer of RBCs in ...

  • Upgrading of decentralized ponds for municipal wastewater treatment and restricted reuse

    Upgrading of a pond system for municipal wastewater treatment in a decentralized area is evaluated. The pond was constructed for the treatment of 63 m3/d. Currently it receives 83 m3/d, therefore poor treatment efficiency was recorded. An expansion of 1.6 times the present land area was required. In addition to construction, operation and maintenance were required to meet the permissible limits. ...
