Hellstein STMH15 for household of 15 persons

The STMH15 wastewater treatment plant is the only one in the Czech Republic to use a modern maintenance-free three-stage treatment system. The STMH15 wastewater treatment plant is designed for an average daily wastewater inflow of approx. 2.25 m3/day (i.e. 2-15 persons). The STMH sewage treatment plant (also a bion tank with a pocket dosing unit) consists of a spherical plastic (PE) tank, fitted with a technological stainless steel built-in, a biodisc and a membrane compressor (blower). The blower can be placed at a distance of 10m from the WWTP itself.
