  • The Municipal Water & Sewage Treatment Sector

    The best reason for the use of Albin Pump Hose pumps in this industry is the low maintenance of the pump. This industry readily accepts an average hose life of 1.500 - 3.000 hours in continuous duty and this hose life will provide much lower maintenance costs and repair time than with other pumps. Basic Pump Requirements For operation in an automatic system the following would ...

  • Toluene in sewage and sludge in wastewater treatment plants

    Toluene is a compound that often occurs in municipal wastewater ranging from detectable levels up to 237 μg/L. Before the year 2000, the presence of the aromatic hydrocarbons was assigned only to external sources. The Enhanced Biological Nutrients Removal Processes (EBNRP) work according to many different schemes and technologies. For high-efficiency biological denitrification and ...

  • Continuous Pyrolysis Facility for Sewage Sludge Treatment

    The amount of sewage sludge is catastrophically increased in the latest few decades due to functioning of the municipal sewage treatment facilities. Dry sewage sludge contains 70-90% of the organic substances and 10-30% of the inorganic substances, which are dangerous for human health in case of inappropriate utilization. The continuous pyrolysis technology presents the unique sewage sludge ...

  • Dogs put trust in onsite sewage treatment

    One of the obvious challenges of running Dogs Trust rehoming centres is the need to dispose of a significant quantity of hazardous waste. All locations not connected to mains drainage have to be served by reliable on site treatment systems and on completion of the latest installation at Salisbury a total of five WPL systems will be in operation around the UK. The charity cares for some 16,000 ...

  • Management of sewage sludge and ash containing radioactive materials

    Approximately 50% of the seven to eight million metric tonnes of municipal sewage sludge produced annually in the US is reused. Beneficial uses of sewage sludge include agricultural land application, land reclamation, forestry, and various commercial applications. Excessive levels of contaminants, however, can limit the potential usefulness of land-applied sewage sludge. A recently completed ...

  • Energy self-sufficient sewage wastewater treatment plants: is optimized anaerobic sludge digestion the key?

    The anaerobic digestion of primary and waste activated sludge generates biogas that can be converted into energy to power the operation of a sewage wastewater treatment plant (WWTP). But can the biogas generated by anaerobic sludge digestion ever completely satisfy the electricity requirements of a WWTP with ‘standard’ energy consumption (i.e. industrial pollution not treated, no ...

  • Case study - Odor treatment in a ventilation shaft of a sewage tunnel

    Bioconservacion’s distributor for municipal biogas and odor applications in Turkey, Biotek Ltd, has recently won a tender for Izmir’s municipal authority IZSU to supply equipment and media for odor abatement coming from a ventilation shaft of a sewage tunnel. These shafts, also known as airshafts or vent shafts, are passages used in different applications such as mines ...

  • 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 ...

  • Image analysis of sludge aggregates obtained at preliminary treatment of sewage

    The results of wastewater treatment by Al and Fe salts and by electrocoagulation with aluminum electrodes are discussed and interpreted. Those processes used alone or combined with biological treatment, were analyzed for 50 and 90% removal of phosphates. Scanning electron microscopy (SEM) of the resulting sludge from three coagulation processes defined the perimeter P and area ...

  • Paraben resistance in bacteria from sewage treatment plant effluents in India

    Parabens, the antimicrobial preservatives used in cosmetics, food and pharmaceuticals, are often detected in the aquatic environment. Generally, sewage treatment plants (STPs) receive community sewage containing parabens, which are ultimately released into streams/rivers. In this study, bacteria in STP effluents were evaluated for their resistance to parabens. The susceptibility was in the order ...

  • From Waste in Anodising Plant to New Chemical Product in Sewage Treatment Plants

    Aluminium containing caustic soda used as a pickling agent in the pre-treatment of aluminium before anodising and aluminium containing sulphuric acids used as electrolytes for the formation of oxide layers in anodising plants can be utilised in municipal sewage treatment plants to reduce phosphates and improve precipitation. From the anodiser's point of view, these products are spent once they ...


  • Case Study: Sandy Balls Leisure Centre: Sewage Treatment Plant

    A customer with a tough application for a Positive Displacement RAS (Return Activated Sludge) Pump was experiencing high maintenance with the existing submersible unit, requiring lifting of the pump every 3-4 weeks, usually due to solids blockage. NOT a pleasant task regularly lifting from raw sewage! Triangle replaced it with a self-priming Boerger Rotary Lobe Pump. A useful feature of the ...

  • ON-SITE SEWAGE SYSTEMS: NEW OUTLOOK FOR DECENTRALIZED WASTEWATER TREATMENT

    As researchers analyze the soils’ ability to absorb discharge, more knowledge is gained about alternatives to septic tanks and standard drain fields that include peat filter systems, constructed wetlands and drip irrigation. ONE out of every four American households currently treat and release wastewater on their own property. Although most people assume that on-site systems are confined to rural ...


  • 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 ...

  • Recovery of Phosphorus from Sewage Sludge

    In the following, a method to recover phosphorus from sewage sludge as MAP (magnesiumammonium- phosphate, also called struvite) is to be presented. The process uses sulfuric acid to leach phosphorus out of digested sewage sludge. After solid-/liquid-separation, interfering metal ions in the liquid phase are inactivated through complexation. For the subsequent precipitation of the phosphorus, ...

  • 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. ...
