ASTIM - Model PST - Central Driven Stirer
Central Driven Stirrer “PST” is designed to be used for Circular Vortex Grit Chambers. The Vortex Grit Chamber’s guided flow pattern represents another breakthrough in grit removal technology. The inlet and outlet channels are designed in such a manner to guide the flow to obtain vortex. The Central Driven Stirrer repeatedly guides the flow and leads grit towards tank’s side walls and to bottom. The rotating axial flow propeller creates an inward radial velocity sweeping the grit to the center. Here the settled grit is either collected by Airlift or Submersible pump.
