1. The efficiency of a TRYBIO household wastewater treatment plant with a hybrid reactor in terms of reducing BOD5 oscillated from 81 to 90%, COD – 64–84%, whereas total suspended solids – 66–89% which, as a rule, was not sufficient to achieve standard levels set for such indicators.
-
2. The best effects of removing organic pollutants expressed as BOD5 and COD were achieved for the following variants: aeration – 2h, dwell – 2h and aeration – 1h, dwell – 0.5h.

3. Removal of organic pollutants from wastewater in the treatment plant with a hybrid reactor was dependent on the dynamics of conversion of nitrogen and phosphorus compounds and indirectly on the thermal and oxygen conditions inside the reactor.
