- Can you estimate potential cost reductions and running costs compared with our existing dewatering equipment?
-
Yes. After reviewing your current operating conditions and receiving your sludge sample, we can prepare an estimate. Through the Sludge Sample Test, we analyze sludge characteristics, evaluate dewatering performance, and select the appropriate polymer. We also simulate the moisture content after dewatering and calculate the estimated cost reduction and running costs.
