Sludge Thickening - an overview ScienceDirect Topics

The sludge concentration achieved in the thickener is independent of the feed concentration. However, the greater the feed volume, the larger the thickener required. There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket fence attachment.

Sludge Thickening Concentration - Wastewater Treatment

Within the hopper, the sludge is slowly mixed with a motorized rack to enhance the release of water. The mechanical stirrer rack is made of a rotating set of vertical blades or rods, which make the stir-rer appear to be a picket fence (this appearance gives rise to the name, picket fence thickener) (Fig. 7.1).

Sludge recirculation settling tank – thickener : the ...

operating principle sludge recirculation settling. Concentrated sludge is recycled at low flow rates via an eccentric rotor pump to prevent floc break-up; as discussed earlier, recirculated sludge multiplies contact surfaces and accelerates floc agglomeration phenomena. Flocculation is optimum in the Densadeg when the floc takes up approximately 10% of the space in the mechanical flocculator.

Picket Fence Thickener (Gravity Thickener).

to thicken sludge increasing density of the sludge before it settles. Function The PFT-gate rotates and is free hanging from the bridge supported by a steady bearing at the bottom, keeping the scraper gate aligned. The picket fence stirs the sludge during settlement and increases the sludge density.

Sludge Thickening - an overview ScienceDirect Topics

The primary objective of sludge thickening is to concentrate the solids, thus reducing the volume of sludge. Thickeners may increase the solids concentration by a factor of 2–5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation. A gravity thickener is shown in Figure 10. The ...
