LAKE CHARLES WWTP B-C LAKE CHARLES PROJECT CP 3128 LDEQ PROJECT CS221215-01 SUBMITTAL FOR Grit Removal System D-11235-001-A 8/9/16 Bill Hussey Submittal Number Date Max Foote Construction Certification Statement: By this submittal, I hereby represent that I have determined and verified all field measurements, field construction criteria, materials, dimensions, catalog numbers and similar data and I have reviewed and approved this submittal and checked and coordinated each item with other applicable approved shop drawings and all contract requirements.
PISTA 360 with V-FORCE BAFFLE 95% Grit Removal Efficiency Down to 140 Mesh (105 Microns) Particle Size The PISTA 360 Grit Chamber is equipped with the patented V-Force Baffle, which is an integral flow control baffle for both the inlet and outlet of the main chamber. The V-Force Baffle directs the inlet flow into the chamber in a manner that ensures the proper vortex flow and prevents short-circuiting. The V-Force Baffle allows for a full 360 rotation from the inlet to the outlet, providing maximum flow travel for effective grit removal. The V-Force Baffle directs the flow out of the PISTA Grit Chamber and acts as a slice weir, controlling the water level in the main chamber and the inlet channel. No additional downstream flow control device is required to keep the velocity between 3.5 fps (1.06 m/s) at peak flow and 1.6 fps (0.48 m/s) at minimum flow with a 10:1 turn down. This most recent innovation further enhances the world s best grit removal scheme by providing engineering and cost saving considerations. By increasing chamber velocity during low flow periods, less grit is permitted to settle in upstream channels. The V-Force Baffle also extends the grit extraction path within the vortex grit chamber. This is a key feature because a longer grit path within the flow pattern dramatically increases the effectiveness of grit being captured on the chamber s flat-floor. Beyond this, the PISTA 360 with V-Force Baffle also permits design flexibility so that water elevations can be controlled. Water level control is important because it maintains the correct velocities approaching the grit chamber. Previously, the most common way to accomplish water level control in the chamber was to back up the flow with a downstream submerged weir. The PISTA 360 with V-Force Baffle has preset inlet and outlet openings that supplant the need for the submerged weir. With all of these improvements, the PISTA 360 with V-Force Baffle achieves 95% grit removal efficiency down to 140 mesh (105 microns). By integrating water elevation settings with the V-Force Baffle, the overall outlet footprint requirements decrease by as much as half the typical distance. The resulting smaller footprint provides significant construction cost savings. The PISTA 360 with V-Force Baffle represents the latest innovation that makes cents from Smith & Loveless. The PISTA 360 with V-Force Baffle is just one of many Smith & Loveless design innovations that make PISTA the world s leading grit removal system.
