The THK Series Thickening Centrifuge from Centrisys is designed to achieve high-performance thickening of biosolids using hydropneumatic technology so no polymer is required under normal conditions. It is nonconical for greater comparative capacity, providing hydropneumatic control of cake solids. It provides independent control of the liquids and solids weir, leading to reduced operating and maintenance costs. It has an optional internal polymer injection system. It comes with tungsten carbide wear plows for grit and trash. 262/654-6006; www.centrisys.com
