How does a backwash plant work?
The plant takes advantage of the region’s often-cold temperatures by using a natural freeze-dry process for treatment of backwash sludge. Instead of highly energy-intensive conventional treatment methods such as presses or centrifuges, each winter the settled backwash residuals are spread in a thin layer and allowed to freeze. This breaks the bonds of hydration and allows the particulate material to separate and settle as the water is returned to the lake. The annual energy savings of this process are well above 100,000 kilowatt hours.
