Most-Specified Inlet Works Systems

Smith & Loveless’ commitment to market leadership in screening technologies and grit removal kindles on-going 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 inlet works. This innovation and experience make S&L systems the industry’s most specified inlet works 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.

Inlet Works Systems

After pioneering the first flat-floor forced vortex grit chamber, S&L continues to lead the industry in advanced hydraulic grit removal research and development by emphasising a combination of CFD analysis and field testing. The state-of-the-art PISTA® is the most-specified in the world, including in New Zealand and Australia. Read More >
