Sludge Thickening Concentration - Wastewater Treatment

Gravity thickener design is very similar to that of primary settling basins. The mechanism of the process is also similar. Due to relatively higher solid content in sludge than that in wastewater, a heavy-duty scraper is often called for in sludge gravity thickening in order to move sludge to a hopper from which it is withdrawn and further ...

HUBER Solutions for Sludge Thickening - HUBER SE

Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and digested sludge can be better gravity-thickened than secondary sludge. Secondary sludge (e.g. waste activated sludge) is preferably thickened mechanically, separate from primary sludge.

Ceramic Membranes in Sludge Thickening Applications

This promising technology shows a great ability to filter water even in the challenging high solids environment of sludge thickening. The results of the pilot testing have led the aerobic digestion group to utilize Cembrane’s membranes as the basis of design for sludge thickening projects moving forward and have signed an exclusive distribution license for the municipal North American market.

Sludge Thickening - Sewage Treatment - Reverse Osmosis ...

Sludge is led inside and through the drum over the flow edge. The spiral screw transports the sludge along the drum and finally out from the drum. The spiral screw mixes sludge slowly inside the drum so that water can come out from sludge very effectively. The horizontal position of the thickener can be lifted up to 10 degree.

Sewage sludge dewatering & sludge thickening | Decanters

Excess sewage sludge that accumulates in the biological stages is thickened from 0.5 - 1% dry solids content to 6 - 8%. This reduces the sludge volume by 90 - 95%. The thickened sewage sludge can then be pumped into a digestion tower. Flottweg designed the C-series OSE decanter (OSE = optimum sludge thickening) specifically for sludge thickening.

Difference Between Clarifier and Thickener

The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not. The ...
