  • High efficiency odour control for wastewater treatment

    Since the banning of sewage sludge disposal at sea in 1998 secondary treatment of sludge is now a vital part of waste water treatment. Initially many water companies opted for incineration, but over the last 10 years other options have been adopted such as producing stabilised sludge and pelletised dried sludge for use as fertiliser for agriculture. Currently over 62% of sludge is used in ...

Built and funded by parent company Bedfordia Group plc this £10 ...

  • New platform for mono’s gunmetal muncher

    The K81 accommodation platform, bridge linked to the NAM gas production platform, houses 24 employees. With every-tightening legislative restrictions and increasing disposal costs, Nederlandse Aardolie Maatschappii B.V. required a cost effective and compliant solution to treat the waste discharged to sea. Proven in offshore installations for over 20 years, the compact twin shaft, low speed Series ...

  • Good bugs and bad bugs

    Ugh, what IS that smell? is usually a question for which no one really wants an answer! The real reason is to make sure the person asking this rhetorical question is not the originator. Anyone walking by some City sewer manholes has had this experience.Beneath the streets of San Diego are literally hundreds of miles of pipes carrying human waste (sewage) from homes and businesses to sewage ...

  • Seabank Power Station, Great Britain

    The challenge was big: For the gas and steam power station in Bristol, Great Britain, that went on stream at the end of the year 2000, the waste water of a near-by sewage plant had to be used as cooling water. Siemens PLC, the designer of the 750 megawatt Seabank Power Station, engaged Grundfos Alldos for this complex and extensive task in chemical engineering. Start of the gigantic project was ...


  • Start up study of UASB reactor treating press mud for biohydrogen production

    Anaerobic digestion of press mud mixed with water for biohydrogen production was performed in continuous fed UASB bioreactor for 120 days. Experiment was conducted by maintaining constant HRT of 30 h and the volume of biohydrogen evolved daily was monitored. Various parameters like COD, VFA, Alkalinity, EC, Volatile solids, pH with respect to biohydrogen production were monitored at regular ...

  • 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 ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
