Aerated wastewater then flows to final settling tanks, exactly where the heavier solids settle to the bottom. We take away most of this secondary sludge and combine it with the primary sludge for thickening and digestion.
Financial investment in wastewater treatment systems is shifting from new design projects to maintenance of initial capacity and function of facilities (asset management).
This produces, for example, the tactic of flocculation filtration. Precipitants and flocculants are added into the wastewater, which will cause flocculation of the substances that could be divided. The wastewater with the flocculated materials is then passed through a cloth or sand filter.
