The key to grit removal excellence with the PISTA® 270™ is its unique flat chamber floor design and forced vortex operation. Now these features have been enhanced with the OPTIFLOW 270® making higher grit removal efficiencies with the PISTA® 270™ Grit Chamber reality. Capacities up to 100 MGD (378,500 cmd) Arrangement 270° with OPTIFLOW 270™ Baffle Removal % 95% down to 100 mesh (150 micron)
With more than 2,500 PISTA® Grit Chamber installations worldwide, Smith & Loveless continues to advance the science of grit removal with the patent pending OPTIFLOW 270® Baffle System for the PISTA® 270™. The OPTIFLOW 270® Baffle System brings previously unachieved grit removal efficiencies to new PISTA® 270™ Grit Chambers, improving grit removal to 95% of 100 mesh (150 micron). Designed by the team that created the PISTA® 270™, the OPTIFLOW 270®B baffle fits inside the grit chamber at the exit, directing the flow toward the hopper for an additional pass along the flat-bottomed chamber floor for grit removal. This revolutionary baffle reduces the weir effect at the outlet, keeping more fine grit within the chamber and improving the toroidal flow path within the PISTA® Grit Chamber. The OPTIFLOW 270®LFB baffle is installed on all units where the lowest flow rate is below 60% of the design rate. This inlet channel baffle maintains influent velocities to provide proper entry velocity into the main chamber vortex.
