Polymer dosage calculations sludge
WebAug 2, 2013 · With mechanical sludge removal, the DAF sludge can be quite thick (2 to 5 percent solids), which eliminates the need for thickening before dewatering. Because of air attachment, polymer is not required for stable performance, as opposed to high rate settling processes that must use polymer to attach particles to ballast. WebUse of polymer does not significantly increase waste sludge production but can be quite expensive, up to $450. per million gallons treated. A polymer supply company should be consulted for selection of a polymer. Jar testing should be performed at your plant to determine the type of polymer needed and its dosage, which are quite plant specific.

WebPolymer Dosage (active lbs/ton TS) Polymer vs Cake Dryness Fairborn WRC C 9530 8868FS B 3210 This Graph represents the results of three (3) different polymers tested at various dosages. It is evident that Polydyne C 9530 produced the best results. The highest cake dryness achieved was 22%TS with a dosage of 25 active pounds per ton TS. Webdosage is 8.8 ppm to yield 10 ppm free EDTA and 26 ppm polymer. If the hardness goes up to 1 ppm or the product is used in another system where the hardness is 1 ppm, the feedwater dosage increases to 43 ppm to obtain 10 ppm free EDTA. This would yield a high polymer level of 129 ppm. Polymer overfeed is expensive and high polymer levels can …
WebWhen operating a centrifugal thickener, every attempt should be made to consistently feed fresh sludge into the thickener. The use of polymers may also enhance solids recovery when using a centrifugal thickener.
