1. 2.Aeration phase Settling phase The wastewater arrives directly in the biological zone without the need for pumping processes. Aeration of the entire container leads to immediate wastewater activation. The microorganisms begin the biological cleaning process without delay. Aeration is interrupted by the control unit, the activated sludge sinks to the bottom. A clear water zone develops in the upper part of the tank. Clear water discharging phase The treated clear water is extracted from the system and the cleaning process can begin once more. Ordinary treatment plants require several chambers...

one2clean / one2c/eanXtraup to 70 PE (10,500 l/day) Components and Benefits As much technology as necessary, as little technology as possible. Over the past few years, wastewater treatment systems have experienced impressive technological developments. Today, they are high-tech products equipped with sophisticated controls and various pumps, sensors and valves. Yet this is often of detriment of product reliability. A reliable wastewater disposal system no longer needs to be complicated. one2clean is an advanced development of the proven SBR wastewater treatment technology, with considerable benefits...

How does SBR technology work? Charging phase The wastewater goes first into primary treatment (1st chamber), where the solid substances are retained. From there, the wastewater is fed into the SBR tank (2nd chamber). Aeration phase The actual biological cleaning by microorganisms now takes place in the SBR tank. Short aeration and rest phases alternate in a controlled cleaning process. The so-called activated sludge can now develop with millions of microorganisms and clean the water thoroughly. Clear water extraction phase The purified wastewater is now fed into a discharge system (stream, river,...
