  • SALVINIA — Standardized MBBRs in Four Sizes
    DAS EE developed with SALVINIA a unique product group that combines effectiveness and compactness with time and cost advantages for our customer....

  • As specialists in the biological treatment of industrial wastewater, we, DAS Environmental Experts, have developed a unique compact plant design called SALVINIA. With SALVINIA 70, SALVINIA 170, SALVINIA 470 and SALVINIA 1060 we offer MBBRs (Moving Bed Biofilm Reactor) in four standard sizes.
    For our customers we combine effectiveness and compactness with time and cost advantages in this product group.

    The MBBRprocess used in the SALVINIAsis primarily utilized for the degradation of organic wastewater constituents as well as ammonium and nitrate loads. The residual substances produced are carbon dioxide, water, nitrogen and small amounts of biomass. 

    Our SALVINIAscan be used, for example, as a low-load stage in a single-stage treatment plant with indirect discharge. They are also suitable as the first part of a two-stage plant with direct discharge. 

    The term SALVINIA, by the way, comes from botany and stands for the genus of floating ferns. Like our wastewater treatment plants, this type of aquatic plant has a particularly purifying effect. This is because they extract excess nutrients from the water and even have an oil-absorbing effect.
