The main wastewater treatment tank is the following stage of wastewater treatment. The pace in the wastewater is approx. 1.five cm/s, appreciably slower than from the sand collector. The reduction of the stream velocity is reached by widening the basin. A low circulation velocity is necessary so which the finer dirt particles can, based upon their character, decide on the bottom or to the water surface area.
