polymer for sludge dewatering

polymer for sludge dewatering

(OP)
Could anyone suggest the best polymer to be used for dewatering hog manure sludge @ 15% solids. The sludge is coming out of a secondary digester. What type of polymer (dry, emulsion) proves best for dewatering??

RE: polymer for sludge dewatering

The real question is whether you need a low cationicity or high cationicity polymer and does the polymer need to be structured or crosslinked, and should the molecular weight be high or low.  Dry and Liquid characteristics are just forms of polymer that can be any cationicity, molecular weight, etc. Dry is less expensive than liquid but generally requires more capital on the front end for the polymer makedown system. Generally, you need to test all of these for the particular manure stream due to variablility in other influences on polymer demand from one site to another.
