ANDRITZ launches new dilution system for thickeners

Oct 12, 2020  The dilution process, where liquid is added to the incoming material and the solids concentration is reduced by adding more solvent, is a critical step. Dilution guarantees a perfect solid-liquid ratio in the thickener feed, which in turn enhances the settling rate of particles in the suspension when flocculants are added.

Thickener Feed System Design - WesTech Engineering, Inc.

Thickeners often require dilution of the feed to improve settling rates and flocculant consumption. Dilution systems that rely on specific gravity differential between the feed and supernatant are often limited. WesTech’s AirLift™ dilution system uses an airlift pump to draw clarified water evenly from the thickener surface into the feedwell.

Flocculant Dilution System in Thickener Feed well

May 14, 2018  In some cases, no flocculation at all is possible unless dilution water is used. The most common method of diluting thickener feed has been to recirculate some of the thickener overflow by- means of a centrifugal pumping system. This represents a significant capital and operating cost.

THE DEAL WITH DILUTION - Outotec

In cases where thickener feed dilution is required, the slurry feed to the thickener is commonly diluted in the . thickener feed system. This improves both the mixing and contact of the solid particles with the flocculant in the thickener feed as contact and adsorption

Jun 16, 2017  Feedwells and flocculant dosing control have a significant influence on thickener performance. Flocculation is controlled by varying the flocculant pump speed to achieve a consistent flocculant dosage rate per ton of dry solids feed. Care should be taken to ensure that flocculant dilution is maintained with changes in flocculant dosing rate.

Feb 06, 2012  dilution water should be secondary or final effluent; If you arer thickening primary sludge your solids loading rate can be up to 15 Lbs/day/sf; If you are thickening WAS it should be no more than 8 Lbs/day/sf and a rate of 4 Lbs/day/sf is better. Even lower can be better. Draw sludge out on a regular basis. Put the underflow pump on a timer.

CHAPTER 3 SLUDGE THICKENING - Mimoza

Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is achieved [1]. ...
