  • Direct sewage filtration for concentration of organic matters by dynamic membrane

    Sewage treatment is experiencing a paradigm shift whereby sewage should be treated as a resource with maximum reuse of water, nutrients and energy. Concentration of sewage for organic matter enrichment is essential for improved energy recovery. In this study, the concentrating performance of direct sewage filtration by a dynamic membrane was investigated. A novel double-layer cloth-media ...

  • Computational fluid dynamics simulations of membrane filtration process adapted for water treatment of aerated sewage lagoons

    The aim of this study is to apply the membrane bioreactor technology in an oxidation ditch in submerged conditions. This new wastewater filtration process will benefit rural areas (<5,000 population equivalent) subject to chronic water shortages by reusing this water for irrigation of green areas. For this purpose, the membranes developed without support are immersed in an aeration well ...

  • High speed municipal sewage treatment in microbial fuel cell integrated with anaerobic membrane filtration system

    A cylindrical two chambered microbial fuel cell (MFC) integrated with an anaerobic membrane filter was designed and constructed to evaluate bioelectricity generation and removal efficiency of organic substrate (glucose or domestic wastewater) depending on organic loading rates (OLRs). The MFC was continuously operated with OLRs 3.75, 5.0, 6.25, and 9.38 kg chemical oxygen demand ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • The use of sewage sludge compost for improving reedbeds performance

    In a wastewater of medium strength, about 75 % of the suspended solids and 40 % of the filterable solids are organic in nature. The parameter used for measuring the strength and the quantity of the organic substances in the wastewater is the Chemical Oxygen Demand (COD) (Aggelakis and Tchobanoglous, 1995; Tchobanoglous and Burton, 1991). Degradable organic matter in wastewater, whether soluble or ...

  • The Method Found In A Sewage Sludge Carbonization Treatment Plant

    Have you ever passes a wastewater treatment plant and wondered exactly how the process works? Most localities have a minimum of one sewage sludge carbonization plant. These plants are the places where municipal sewage sludge is treated. This process is split into three stages. Each stage was created to further decompose and disintegrate wastewater sludge. ...


  • Recovery of reusable water from sewage using aerated flat-sheet membranes

    Continuous developments and advances in membrane technology allow recovering to large extent reusable water from untraditional water sources, such as municipal effluents. In this paper, operational results and preliminary cost-analysis of a microfiltration (MF) process used for raw sewage and secondary effluent polishing are given. The research was conducted with a 22 sandwich-type flat-sheet ...

  • Considering energy efficiency in filtration of engineering nanoparticles

    Engineering nanoparticles (ENPs) are an integral part of consumer products. Released to the atmosphere or disposed to sewage, ENPs quickly penetrate to surface and ground water sources. An absence of a dedicated ENP-retaining water treatment strategy imposes a potential health threat on drinking water consumers. The threat is met by gearing up an upgrade of treatment systems towards membrane ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Enhanced physicochemical-biological sewage treatment process in cold regions

    Biological treatment processes give relatively poor pollutant removal efficiencies in cold regions because microbial activity is inhibited at low temperatures. We developed an enhanced physicochemical-biological wastewater treatment process that involves micro-membrane filtration, anaerobic biofilter, and aerobic biofilter to improve the pollutant removal efficiencies that can be achieved under ...

  • Sewage pre-concentration for maximum recovery and reuse at decentralized level

    Pre-concentration of municipal wastewater by chemically enhanced primary treatment (CEPT) was studied under controlled laboratory conditions. Both iron and aluminium-based coagulants were examined at gradually increasing concentrations (0.23, 0.35, 0.70 and 1.05 mmol/L). The CEPT sludge generated from different coagulation experiments was digested in batch anaerobic reactors, while the ...

  • Separation of metals and phosphorus from incinerated sewage sludge ash

    Microbial acidification of incinerated sewage sludge ash and dissolution of metals from the acidified ash were investigated using a semi-batch reactor at different solid retention times (SRTs). The average pH values ranged from 0.91 to 1.2 at SRTs longer than 10 days, whereas the reduction of SRT to 4 days resulted in an increase in the pH value to about 2. The dissolution efficiencies of Al, ...

  • Intermittent operation of low pressure UF membranes for sewage reuse at household level

    A household-scale wastewater treatment system was operated with domestic sewage. The system could recover gardening/irrigation water from raw sewage or secondary effluent by low pressure ultrafiltration (UF). The UF membranes (surface area = 3.5 m2, pore size = 0.04 μm) were operated at constant transmembrane pressure (0.13 bar). The proposed technology was examined for ...

  • Pollutant removal and membrane fouling in an anaerobic submerged membrane bioreactor for real sewage treatment

    Real sewage was continuously treated by a laboratory-scale anaerobic submerged membrane bioreactor (AnSMBR) for over 160 days. Results showed that around 90% of chemical oxygen demand, and 99% of turbidity and total suspended solids in the sewage could be removed by the AnSMBR system. Membrane flux sustained at 11 L/(m2 h) was realized with biogas sparging. Small flocs from sludge ...
