How to Optimize Polymer Efficiency for Better Sludge Dewatering
There are several types of sludge that have specific characteristics that will influence: The choice in conditioning chemical (cationic flocculant, ferric chloride, lime1⁄4) The choice in the dewatering equipment to be used (filtration, centrifuge1⁄4) These choices will also depend on the final use of the sludge (incineration, agricultural spr...

Cationic polymer application in DAF units - DigitalRefining
Cationic polymer is very effective in sludge dewatering and DAF operations. Polymer is used as cationic flocculant before several laboratory and jar tests over a wide range of conditions especially performed in the field. Since water characteristic are different for a Refinery wastewaters, different dosages rates within a range are proposed.

Sludge dewatering using centrifuge with thermal/polymer
Cationic polymer exhibits the best enhancement on sludge moisture removal. The sludge rheogram varies from 60 to 5 cP as temperature changes from 20 to 80 degrees C for sludges from water treatment plant. The dewatering ability of sludge can be greatly enhanced by thermal treatment in conjunction with the use of polymers.

Wastewater treatment - Sludge, Disposal, Treatment | Britannica
Wastewater treatment - Sludge, Disposal, Treatment: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical

Sludge Dewatering - an overview | ScienceDirect Topics
The main targets of sludge treatment are volume reduction and substance degradation. The most common conventional processes include sludge thickening, dewatering, and drying. Figure 9.1 presents the sludge solid content (% of dry mass) during the sludge dewatering processes. After thickening, the sludge mass is usually reduced up to 70% of the

Wastewater treatment polymers usually come in either a dry granular form or a liquid, emulsion form. Emulsion polymers are much easier to feed, dissolve into a water solution, and activate. The shelf life of an emulsion polymer is around 6 months. Dry polymers require expensive equipment and a difficult process to dissolve and activate.
