WEAO sludge dewatering

Sludge Dewatering

The sludge dewatering system works like this: Liquid sludge is pumped through an in-line static mixer where it is blended with polymer. From there, the sludge/polymer mixture continues into the Sludge Dewatering Unit. The same pump is utilized since mixing occurs on the fly and in-line. Once in the Sludge Dewatering Unit, solids are dewatered in a predetermined period of time. In a properly designed Dewatering System, 60-70 percent of free water should have drained within a matter of minutes if flow rate, polymer, and filter media are properly mated during the design phase. In many applications, solids will reach a dryness of 12-20 percent within 18-24 hours. Solids of this dryness should easily pass the Paint Filter Test.
