  • UASB-CFID system: energy efficient technology for sewage treatment and reuse

    The UASB-CFID system was investigated through laboratory experiments as an alternative method of treatment to existing UASB based STPs for the treatment. Excellent quality effluent was obtained having BOD and TSS below the disposal standards of India. In conventional treatment methods, lot of energy is wasted and also they generate harmful byproducts. The estimated life cycle cost of UASB-CFID ...

  • Sewage Treatment - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    Sewage treatment plant operate by providing an environment in which aerobic bacteria are cultured. These bacteria survive by using biological matter in the sewage as a food source. To provide optimum treatment the bacteria need free access to oxygen and immersion in the sewage effluent. The majority of package plant work by providing a fixed medium that the bacteria adhere to, and a means of ...

  • Sewage Pump - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    There are a variety of solutions on the market for properties in the UK that are unable to connect to the main sewer by gravity. However, UK building regulations dictate that pumping stations must be used whenever possible. As a result, pumping stations are the most commonly specified solutions for off-mains developments, ahead of sewage treatment plants, such as the Biodisc, and septic tanks. ...

  • Study on sewage sludge gasification

    Aimed at creating new technology to reduct greenhouse gas emission, the Tokyo Bureau of Sewerage has developed a system generating electricity with a gas engine using biogas generated by pyrolytic gasification of sewage sludge in a fluidized-bed gasifier. A 15t/d demonstration facility was built based on a dehydrated sludge and demonstration tests were run for 3400 hours from 2005. As a result of ...

  • Specific energy consumption of membrane bioreactor (MBR) for sewage treatment

    This paper provides an overview of current electric energy consumption of full-scale municipal MBR installations based on literature review and case studies. Energy requirements of several MBRs were linked to operational parameters and reactor performance. Total and specific energy consumption data were analysed on a long-term basis with special attention given to treated flow, design capacity, ...

  • Sensitivity analysis for the SimpleTreat model to simulate fate of chemicals in sewage treatment plants

    SimpleTreat 3.1 predicts the distribution and elimination of chemicals by sewage treatment. The model is used as the default calculation in EUSES 2.0 to estimate exposure concentration in the receiving water, soil and air. A sensitivity analysis was performed to rank input parameters according to their influence on model predictions. Triclosan was selected for the base case. The sewage flow, ...

  • Development of a down-flow hanging sponge reactor for the treatment of low strength sewage

    The process performance of a down-flow hanging sponge (DHS) reactor for treating low strength sewage (biochemical oxygen demand (BOD) 20–50 mg/L) was investigated in Bangkok, Thailand. The hydraulic retention time (HRT) was set at 4 h during the start-up period and was reduced to 1.5 h in a stepwise manner. Throughout the 300-day operational period, the DHS reactor shows high performance ...

  • Costs comparison of Sewage Treament Plants

    Don’t consider the initial purchase cost of Sewage Treatment systems as the only costs to look at when looking to buy a Sewage Treatment Plant. Check the "hidden" expenses before purchasing your Sewage Treatment Plant otherwise you may pay thousands of pounds more than anticipated because of the the installation, emptying and maintenance costs of your sewage treatment plant. Here is the ...

  • Water quality simulation of sewage impacts on the west coast of Mumbai, India

    Most coastal cities use the ocean as a site of waste disposal where pollutant loading degrades the quality of coastal waters. Presently, the west coast of Mumbai receives partially treated effluent from wastewater treatment facilities through ocean outfalls and discharges into creeks as well as wastewater/sewage from various open drains and nallahs which affect the water quality of creek and ...
