Block-modular underground plants are intended for deep biological treatment of household and domestic sewage from 8 to 25 m³/day. We recommend the use of such plants with a low groundwater level and the presence of prefabricated reinforced concrete elements.
On a joint reinforced concrete plate there are installed six reinforced concrete wells. In two wells are placed polypropylene bioreactors SBR2 and SBR3. In the well of the receiving chamber, aeration systems and sewage water pumps are installed. Sludge tank is provided for the accumulation of surplus activated sludge. Biofilter loads and circulation airlifts are mounted in the biofilter well. Decontamination of treated sewage is provided in the contact tank.
Please note! The warranty period for BIOTAL plants is 5 years, for the control unit and blowers – 3 years, for pumping equipment – 2 years.
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.
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.
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.
The ultraviolet water disinfection unit is equipped with a lamp with radiation in the UV-C range with a wavelength of 254 nm.
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.
