  • Aerobic Wastewater Treatment

    Aerobic waste water treatment converts the organic pollutants (COD, BOD) in wastewater into sludge, and oxidizes the rest with oxygen (air) into carbon dioxide. The amount of sludge generated by an aerobic system is greater than that produced by an anaerobic system. Biothane typically recommends an anaerobic system to its customers, due in part to the high operating costs for aeration, sludge treatment and sludge disposal. However, we offer an aerobic process as a complementary polishing t

  • Biothane - Conventional Activated Sludge System

    Biothane - Conventional Activated Sludge System

    The conventional activated sludge system comprises an aeration tank and a clarifier. Aerobic biomass degrades COD in the aeration tank. The mixed liquor (ML) in the clarifier is separated into a water phase and a concentrated ML by sedimentation. The clarified water overflows weirs at the top of the clarifier whereas the sludge (biomass) is removed at the bottom. The major part of the biomass is recycled to the aeration tank to maintain the required...

  • Biothane - Model SBR - Sequence Batch Reactor

    Biothane - Model SBR - Sequence Batch Reactor

    The SBR process consists of two reactor tanks with a common inlet system. The bio-selector at the influent section contains baffles to mix the reactor content and enhances digestion. The treatment step is followed by a settling phase, which runs parallel with the filling and aeration of the second tank. The treated water is discharged and the solids are extracted at the reactor bottom.

  • Biothane - Model MBR - Membrane Bioreactors

    Biothane - Model MBR - Membrane Bioreactors

    In membrane bioreactors ultrafiltration (UF) or microfiltration (MF) membranes are used for separation of the treated water from the mixed liquor (ML). The UF/MF membranes guarantee a constant and very high effluent quality as particulate matter (SS, microorganisms) cannot pass through the membranes. Furthermore, MBR installations require less space than conventional activated sludge systems because more biomass can be retained in the system allowing...
