  • Busting Biomethane Myths

    Over the past few years, more and more companies have woken up to the financial and environmental benefits to be gained by making the most of their organic waste streams. In fact, the anaerobic digestion (AD) industry – which converts millions of tonnes of food, sewage and farm waste into renewable energy (biogas) and biofertiliser – has been one of the UK’s biggest success ...

  • Stop the hit and miss in coagulation-flocculation: AppliTek’s charge density analyzer to reduce polymer dosing

    Specialist manufacturer AppliTek NV has the pleasure to announce its latest analytical solution, called EZ-Charge®, for reducing the potentially skyrocketing costs that come with controlling the amount of suspended solids in waste water treatment. The novel water analyzer has been developed in cooperation with AQRatio (Germany), a company specialized in sewage sludge analysis and control. ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • City Of North Bay Uses Condition Assessment On Critical Force Main To Implement Asset Management Plan

    On one hand, it may seem like a waste of capital dollars if you perform a pipeline condition assessment and the final analysis turns up no leaks. Alternatively, you can also look at the no-leak report as a good news validation story, especially when using the information to help establish an asset management ...

  • Analysis of Sewage and Sewage Sludge by Simultaneous ICP Spectroscopy

    In recent years, the development and expansion of sewage treatment facilities has resulted in increased amounts of sludge which is generated in the treatment process, and which has presented a problem due to processing of the sludge itself. Sludge is normally incinerated or solidified and then disposed of in landfills or recycled for use in construction materials such as concrete or ...

  • 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 ...

  • An alternative to biological treatment for sewage

    Most sea-side towns discharge sewage into the sea, normally some distance off-shore, via an extended out-fall sewer. A town of 100,000 population will produce more than 14,000 cubic metres (3,000,000 gallons) of sewage every day of the year. No small problem. In some coastal locations the sewage used to receive only basic, simple treatment, usually  "screening" to remove any large ...

  • Sewage sludge management in Malaysia

    This paper describes the current status of sewage sludge management in Malaysia, including sludge characteristics from both communal sewage treatment facilities and septic tanks. The levels of potentially toxic elements in the sludge are defined and compared to levels elsewhere in the context of the suitability of the sludge for agricultural use. Current sludge disposal practices are reviewed and ...

  • Southeast Georgia sewage treatment

    Problem: A WWTP in Southeast Georgia located on a resort island has a 3 million gallon per day flow. The WWTP was experiencing major odor problems at the head of the plant, as well as poor digestion and settling of bio-solids in the SBR’s and aerobic digesters. The odors were primarily H2S and were the source of numerous complaints from the residents living in the vicinity of the WWTP. The plant ...

  • Sewage treatment plant

    BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...

  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...

  • Sewage treatment plant case study

    Contributing to snowy regions in which the transportation of sludge is difficult In municipal wastewater treatment plant in snowy regions, snow-bound in winter, taking dewatered cake out regularly is sometimes difficult. Two problems were also presented in this municipal wastewater treatment plant, i.e., the difficulty of taking sludge out using carriers in winter, which had been ...
