95% Grit Removal (105 microns) at All Flows
Smith & Loveless’ headworks systems, with innovative screening technologies and grit removal systems, benefit from our on-going commitment to research and development, which leads to continued system innovations. Since the introduction of the original vortex PISTA® Grit Chamber in the early 1970s, and with decades of screen innovation, S&L has developed numerous advancements to further enhance the capability for complete headworks. This innovation and experience make S&L systems the industry’s most specified headworks systems today.
High removal efficiencies originate from the PISTA® Grit Chamber’s unparalleled hydraulic design, including its flat chamber floor, patented and low-energy axial-flow propeller. The combination creates a true vortex that effectively separates grit from organics and the waste stream. Forced vortex action distinguishes the PISTA® Grit Chamber from all other so-called “vortex” grit chambers because it does not rely on less efficient particle settling or gravity.
