The PISTA® VIO™ Grit Removal System provides leading grit removal efficiencies and unprecedented application flexibility with a design that allows for full variability of the inlet and outlet channels.
This type of grit removal system —one of the first of its kind in the industry—provides the ability to design the inlet and outlet channels at any variable angle up to the full 360° of the chamber. Designers can flexibly arrange the system to fit existing sites, or maximize space during construction on new sites.
This new baffle system, in addition to providing application flexibility, also offers superior grit removal efficiency. The PISTA® VIO™ features a hydraulic vortex grit chamber design that utilizes a new baffle system to create the vortex action that removes 95 percent of grit down to 100 microns. Its effluent flume design minimizes the harmful weir effect that can contribute to grit bypass.
