The continuous circulation of sewage about these growths permits the microbes to absorb the dissolved organics, As a result decreasing the biochemical oxygen demand from customers (BOD) on the sewage. Air circulating upward through the Areas Amongst the stones gives adequate oxygen to the metabolic processes.
four. Stage: Membrane processes / Nanofiltration In the fourth and remaining cleansing phase, membrane and filter processes are applied. Partly, this purification stage is combined with the chemical processes of precipitation and flocculation.
Phosphates are eradicated with a chemical precipitation or flocculation process. The phosphate precipitation is partly triggered by the addition of aluminium or iron salts within the sand collector or within the secondary wastewater treatment tank. The metal-phosphate flocks which have been formed for the duration of this secondary clarification are then taken out with the wastewater together with the activated sludge. Dependant upon the method of operation, the phosphate can even be "fished" with the help of microorganisms from the wastewater. In this case we converse of a biological phosphorus elimination, and that is, nevertheless, even now seldom applied.
