The wastewater treatment facilities type ВТ 200 – ВТ 2000 is designed for purification of large secondary sources of wastewater: villages, resorts, small towns, camping sites, hotels, housing cooperatives and some industrial enterprises with domestic faecal contamination.
The wastewater treatment facilities are made of modular design polymers or concrete construction. The facility is divided by parts into several parts, matching the different processes.
