PISTA® 360™ with V-Force BaffleSource: Smith & Loveless, Inc.
Featured in WEFTEC.13 Booth 2654, the Smith & Loveless PISTA® 360™ grit removal system with patented V-Force Baffle™ captures 95 percent of grit particles down to 140 mesh / 105 microns. Equally as important, it provides practical engineering benefits during the design phase and significant cost-saving considerations for municipalities at installation and beyond.
To accomplish this, the PISTA® 360™ design increases velocity during low flow periods while maintaining consistent grit capture during surges. Its V-Force Baffle™ uniquely positions within a 360-degree, flat-floor grit chamber, helps comprise a patented hydraulic design within in the chamber. The integral baffle design also serves as a water level control device, often eliminating the need for downstream flow control devices like weirs. By integrating the water elevation settings with the baffle, the overall outlet footprint requirements decrease as much as half the typical distance. This also affords design engineers the flexibility to permit the outlet channel to make sharp turns – as much as 90 degrees – immediately following the circular chamber.
Its ability to handle significant variances between design and peak flow conditions (in single units) can eliminate the need for multiple grit chamber arrangements, which in turn, lowers initial capital and long-term operational costs. Because the system doesn’t require pumps for velocity control, its energy requirements are less than stacked-tray and aerated grit chamber designs.
