BIOTAL Water Treatment Plant is designed for the treatment of domestic and sewage waste waters of residential and business buildings, biologically treatable industrial waste waters of small productions, petrol stations (complex – domestic-sewage-rain waters - and car wash waters)
      Considering the specific operation features of small treatment plant, which function under conditions of high irregularity of hydraulic and organic loads and changes in the composition and properties of arriving waste waters, BIOTAL engineering solutions were mainly directed to ensuring high quality of treated waters and stable operation with reasonable capital investments and energy consumption.
      BIOTAL Water Treatment Plant involves various new patent-protected technical solutions, which allow a comprehensive solution of the problems of small water treatment facilities.
      At present over 4000 Water Treatment Plant BIOTAL are already installed in Russia, Czech Republic, Ukraine, Bulgaria, Moldova и Belarus.
      1. As a result of the treatment process, the machines make two final products, both suitable for direct end consumption:
                  -  Treated water, which can be further used;
      -  Organic-mineral fertilizer in the form of stabilized and compacted surplus active sediments;
      2. Thanks to the design of the treatment technology, no methane and hydrogen sulfide are released during operation, and that’s why there are no unpleasant smells at any stage of the waste water treatment, which allows the system to be installed in the immediate vicinity to the serviced site.
      3. The systems are completely automatic and do not require any full-time service personnel. The treatment process is controlled by controller, which allows the optimization of the operating process regarding the consumption of electric power and element operating resources; in particular, it ensures the consecutive automatic switching of the system into first, and then into second, Economy Mode of Operation, if there are no incoming waste waters after 1 and 24 hours, respectively, and into a Forced Mode of Operation – if waste water quantity is bigger than the design value. The controller display shows the actual system operation – the waste water treatment phase of the system at a certain time, the operating facilities, the Mode of Operation of the System, (Economy, Normal or Forced).
      4. There is also emergency alarm in the following cases:
                  - Electric blackout;
                  - Breakdown of any of the units;
                  - The filter bags are full with surplus active sediments;
      5. In case of an electric blackout, during the first 24 hours the system discharges the water treated earlier. Then it begins to function as a multi-level settling tank, thus ensuring that waste waters are cleaned from oils and floating dirt – the main enemies to all drainage systems. When the electric supply is restored, the system again switches into a normal mode of operation.
      6. It is possible the system can be equipped with automated complete mechanical preliminary wastewater treatment.
      7. If there are higher requirements to the quality of treated waters, the system can be equipped with a self-cleaning filter and an ultraviolet decontamination unit, and the cleaning water will be returned to the receiving chamber.
