Capacity of monoblock plants (BIOTAL-ERD) of increased strength is from 1.5 to 10 m³/day. This type of monoblock plant is designed for underground installation in dry ground (the groundwater level should not be higher than the bottom of the plant). The shell of the plant is all-welded, with ribs of rigidity, which ensure the strength of the shell during underground installation without the use of ferro-concrete wells. Installation of the plant is carried out on a concrete foundation with layered filling of sand with the addition of cement.

Installation features

The automatic control unit of the BIOTAL plant and the blower can be installed in an existing non-residential heated room equipped with ventilation, a specially constructed blower building or in a box-recuperator that is installed in the plant ceiling. Cables and air ducts must be laid in protective cases. The maximum distance from the plant to the blower building is 20 meters. The drainage of treated sewage is possible by gravity or by a pump installed in the tertiary settler of the plant.

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

Service maintenance of monobloc installation BIOTAL we recommend to conduct: for private sector objects (cottages, private and country houses, mansions …) – once a quarter, and for other types of objects (gas stations, cafes, hotels, production .. .) – 1 time per month. ”


  • 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.
