  • Trials at a sewage treatment plant in Moscow Case Study

    At Moscow WWTPs (Kuryanovsky and Luberetsky) ,each having water capacity of 2,5 mln m3/day, all mixture of primary and secondary sludge is digested at 53 °C with SRT=HRT 7 days. The volatile solid reduction (VSR) is about 43-46% and gas production is about 0.33 m3/kg VS fed. In order to increase VSR and gas production many different optimization variants were studied. One of them was ...

  • UF Membrane Technology

    UF Membrane Technology Ultrafiltration (UF) is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of ...

  • Wastewater Treatment: Out with Conventional, in with Sustainable Wastewater Treatment

    The question?Water is one of the world’s most vital resources. It is critical to the survival of every living creature on the planet. The average human can only go a few days without consuming water in some capacity. Health experts stress drinking fluids throughout the day to remain properly hydrated. However, in some parts of the world, water is hard to obtain. Either there are no sources ...

  • One of Europe’s largest wastewater plants handles 2 million challenges a day. What are yours? - Case Study

    In Ambarli, Turkey, more than two million people depend on the capabilities of just one wastewater treatment plant. But as strict new environmental regulations came into effect, the city’s outdated facilities became unsustainable. To meet new demands, the new facility would need to treat 400,000 cubic meters of sewage per day within a very compact building. Technologies, costs, ...
