The PISTA Vio Grit Removal System from Smith & Loveless provides design flexibility to go with removal efficiencies. It can be designed with the inlet and outlet channels at any variable angle up to the full 360 degrees of the chamber, offering simple installation into existing sites or an efficient footprint for new sites. With the use of a hydraulically forced ring and tunnel system, it creates the vortex flow path necessary to provide 95 percent grit removal down to 140 mesh/105 microns. 800/898-9122; www.smithandloveless.com; Booth 5539.
