How is solidsseparation controlled in primary wastewater

Air-to-solids ratio An optimum ratio should be established and maintained. It is affected by the quantity of air introduced and dissolved into the recycle or waste-stream, which is in turn critical to flotation thickener operation. Enough air has to be added and dissolved to float the sludge solids.

Optimise your thickener efficiency for maximum

Flocculants are used in most thickeners to obtain concentrations of overflow solids that will allow water to be reused or to comply with government regulations if the overflow is to be discharged. Recycled water containing 200 mgL to 1 solids is generally acceptable. Most thickeners can achieve this level of concentration by using a flocculant.
