Usually, the sludge in waste water or drinking water treatment plants, after decanting and/or thickening, reaches the Screwmax: slow-speed sludge dewatering system. (patented) These sludge, prior to enter the machine, must be mixed normally in a tank in order that the sludge is homogeneous and the floc is generated correctly.

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 ...

A gravity thickener is similar to a conventional sedimentation tank in design, but has a more steep floor slope. Tanks range from 6 – 20 m dia & side water depth (SWD) may vary from 3 – 4 m. Floor slope is varies from 1:4 to 1:6 depending upon the type of sludge, time required for thickening & storage volume to absorb peak solids load.

So-called "swirl separators," an example of which is illustrated in Figure 7-98, are devices that use a relatively low centrifugal force to separate grit.The source of energy for these devices is normally a pump. The pump causes wastewater to flow through the swirl separator at a velocity sufficient to cause grit, or other high specific gravity material, to be thrown to the outside of the ...
