The arriving waste water will be collected in the left chamber. First dirt particles settle out. The compressed air sensor controls the continuous transportation into the biological cleaning chamber (right container half) according to requirements depending on the waste water quantity.
… The waste water is biologically cleaned by oxygen supply and circulation. The automatic control optimises the venting time steplessly and guarantees that always only the actually necessary energy is used. …
… The heavier bio mass sinks to the bottom during the settling out phase; a “clear water zone” with the cleared waste water forms in the upper region.
… the reliable air-lift pump takes the cleared water “into the open” – directly into a body of water or for leaching.
The biomass generated at the same time is, however, returned into the settling out chamber …
The cleaning process starts again.
