16. Comparison WPN vs. Centrifuge
Cake dry solids content: 28 %
Polymer consumption (6-8 kg/t DS)
Low energy comsumption (4-5 kW)
Low maintenance costs
Clear filtrate: ~ 500 mg/l
Cake dry solids content: 28 %
Polymer consumption (13-15 kg/t DS)
Low energy comsumption (40-50 kW)
High maintenance costs - fast running machine
Dirty filtrate: ~ 2000 mg/l

17. Savings by Using a Winklepress instead of a Centrifuge
Operation costs:
