The IFT Rotary Drum Sludge Thickener from JWC Environmental achieves 5 to 15 percent solids for municipal wastewater biosolids. The Rotary Drum Thickener uses woven wire mesh screening panels that allow for capture rates in excess of 98 percent and a much lower polymer use. The drums are constructed with easily removable panels for drum retrofit or repair. The IFT is also fully enclosed to control odors in the thickening area. The extremely short dwell time in the mixing tank drives a smaller equipment footprint and low polymer requirements. 800/331-2277; www.jwce.com; Booth 4516.
