The biggest expense in dealing with biosolids has to do with water — specifically, separating it from the solids. The less water content, the lower the cost to haul, landfill, or incinerate the material.
That’s why makers of dewatering presses and centrifuges strive constantly to improve their technologies to yield a drier end product. A few percentage points improvement in solids content can make a big difference in a clean-water plant’s operating expense.
Flottweg Separation Technology, a company specializing in separation technologies, introduced a new decanter centrifuge at the Water Environment Federation Annual Technical Exhibition and Conference in October. It uses
