Biosolids dewatering can offer enormous potential savings for operators of sewage treatment plants. Depending on system capacity, 1 percent more dry substance can lead to cost-savings in the five- to six-digit range. With that potential savings in mind, Flottweg Separation Technology has introduced the Xelletor decanter centrifuge, which uses innovative technology to improve dewatering performance, reduce polymer consumption, save energy and maximize capacity.
The key to the device’s dewatering performance is a deeper liquid pool inside the centrifuge, translating to greater volume and higher throughput. The deeper pool enables production of solids that are drier on average by 2 percentage points
