Membrane thickening aerobic digestion processes Water

Membrane thickening aerobic digestion processes offer many advantages including producing a reusable quality permeate with minimal levels of total phosphorus and nitrogen that can be recycled to the head works of a plant protecting the performance of a biological nutrient removal liquid treatment process without requiring chemical addition

Thickening Lenntech

At smaller wastewater treatment plants where the sludge is driven off regularly thickening usually takes place directly in the sludge storage tank The sludge is compressed at the tank bottom only by the force of gravity while above the sludge a cloudy water layer

How a Thickener Works Mineral Processing amp Metallurgy

20191116 ensp 0183 enspThickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids The early methods of thickening employed plain flatbottomed tanks into which the pulp was fed until the tank was full The solids were then allowed to settle as long as required the top liquid was decanted the settled solids were
