The digestion process from the digestion tower is completed after around four weeks. What stays is an odourless sludge, which can be generally used in agriculture soon after dewatering by centrifuge or filter.
The flocculation basin normally has numerous compartments with decreasing mixing speeds as the water advances throughout the basin. This compartmentalized chamber makes it possible for ever more substantial flocs to type with no becoming damaged apart because of the mixing blades.
Phosphates are taken off that has a chemical precipitation or flocculation process. The phosphate precipitation is partly activated via the addition of aluminium or iron salts in the sand collector or during the secondary wastewater treatment tank. The metallic-phosphate flocks that are formed during this secondary clarification are then taken out of the wastewater along with the activated sludge. Depending upon the method of operation, the phosphate can also be "fished" with the help of microorganisms through the wastewater. In cases like this we speak of a biological phosphorus elimination, that's, even so, even now seldom made use of.
