PISTA® TURBO™ Grit Washer

The PISTA® TURBO™ Grit Washer uses TRI-CLEANSE TECHNOLOGY™ to match the high fine grit removal efficiency of the chamber and to produce clean grit while minimizing the odor caused by putrescible organics and the costs associated with growing landfill restrictions. Smith & Loveless’s PISTA® TURBO™ Grit Washer featuring TRI-CLEANSE TECHNOLOGY™ boasts a sleek, compact design with a similar footprint to S&L’s screw conveyor.

The PISTA® TURBO™ Grit Washer uses an inlet hopper to receive the mixture of water and grit from the second stage PISTA® Grit Concentrator, and is equipped with an energy dissipation zone to prevent turbulence in the remaining portion of the hopper. Parallel plates located in the settling zone of the hopper improve the retention of fine grit. When pairing with the PISTA VIO or PISTA® with V-FORCE BAFFLE™, the system efficiency will maintain its 95% removal efficiency down to 140 mesh (105 µ).

The custom-engineered and patented screw contains mixer, fluidizing vanes in the washer hopper with a continuous shaft design off the flight segment.

A PLC controller provides the necessary control functions to properly operate the PISTA® TURBO™ Grit Washer through its various cycles and to control the operation of the air infusion, grit wash water and spray water.
