Inspired by extensive expert CFD modeling and developed rigorously in actual field conditions, the patent-pending PISTA® Grit INVORSOR™ combines the power of proven particle capture methods: enhanced settling by inclined plates meeting a defined surface overflow rate [SOR] with the established hydraulic forced vortex to achieve industry-best, ultra-fine grit removal efficiency down to 75-micron particle size across all flows with no derating.
Compared to other fine particle grit removal systems, the INVORSOR™ delivers lower capital and operational costs, larger capacity in individual units, greater design flexibility for inlet-outlet design options and a higher surface area-to-volume ration to generate consistent fine frit capture during low flow, daily flow and peak flow conditions — up to 50 MGD in single units [190,000 m3/d].
