OPTIFLOW 270® Baffle System Retrofit

OPTIFLOW 270® Baffle System Retrofit

Tax included

The key to grit removal excellence is a flat chamber floor design and forced vortex operation. With the OPTIFLOW 270® STF any sloped floor vortex system can now be converted into a flat floor. The OPTIFLOW 270® is making higher grit removal efficiencies an any 270 degree forced vortex grit chamber a reality. Capacities up to 100 MGD (378,500 cmd) Arrangement 270° with OPTIFLOW 270™ Baffle Removal % 95% down to 100 mesh


With more than 2,500 PISTA® Grit Chamber installations worldwide, Smith & Loveless continues to advance the science of grit removal with the new patent pending OPTIFLOW 270® Baffle System for any 270° vortex unit. The OPTIFLOW 270® Baffle System brings previously unachieved grit removal efficiencies to any 270° vortex unit, improving grit removal to 95% of 100 mesh (150 micron) during peak and low flows alike. 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 system 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.
