Primary treatment at municipal treatment plant. Designed to reduce BOD and solids loading to an overloaded lagoon system.
Secondary (WAS) sludge thickening system increasing solids from <1% to 6 to 8%+ prior to hauling for disposal.
Polymer consumption for this type of application is typically 4 to 9 kg/ton of dry solids as a function of the sludge.
We get 6 to 8% easily, and often exceed this. To point out the strengths of our design, we have handled feed solids from 0.2% and up, used 5 kg/ton and still met the 6 to 8% promised and delivered solids at 13%+ in some applications.
