Block-modular ground-underground plants

BIOTAL BMT – BIOTAL wastewater treatment

Dimensions

Use

Block-modular underground plants are designed for deep biological treatment of domestic waste water with a volume of 8 to 25 m3/day. We recommend the use of such facilities with a low groundwater level and the availability of prefabricated reinforced concrete elements.

Installation features

Receiving chamber-denitrifier, surplus activated sludge tank, biological filter tank and the contact tank are made from reinforced concrete and are located in the underground part of the treatment facilities. The walls of the reinforced concrete underground part serve as the foundation for the walls of the ground part of the treatment facilities, where the SBR2 and SBR3 polypropylene bioreactors, blowers and automatic control unit of the plant are located.

Please note! The warranty period for BIOTAL plants is 5 years, for the control unit and blowers – 3 years, for pumping equipment – 2 years.

Glossary:

  • Stainless grid for coarse impurities detention
    Detention of coarse impurities at the BIOTAL plant takes place in a large stainless grid with two-sided air bubbling and a fixed cover.
  • Siphon airlift
    A device designed to transfer treated sewage into a biofilter-tertiary settler, the design of which prevents entering of surface contaminants to the next cleaning zone.
  • Biological filter
    Self-cleaning biological filter provides post-treatment of waste water, and also works as a thin-layer settler.
  • Water level sensor
    Is designed for the timely delivery of signals to the automation of the plant, which in turn automatically switches the system into one of 7 programs, which saves up to 70% of electricity.
  • UV disinfection
    The ultraviolet water disinfection unit is equipped with a lamp with radiation in the UV-C range with a wavelength of 254 nm.
  • Aerator
    The aerator is made of PUR membrane with laser perforation, provides small-bubble aeration of waste water, which allows to increase the efficiency of saturation of sewage with oxygen, and also improves the absorption properties of bacteria of activated sludge.
