The Mectan™ vortex grit system is a circular chamber that takes full advantage of the tangential inflow velocity along the peripheral wall of the chamber to assist in the grit removal process. The circular design will handle large flow rates in a fraction of the footprint of conventional aerated units. The grit is transferred from the grit well to classifier via pump or air-lift.
Mectan V is the new generation for induced vortex grit removal for wastewater pretreatment applications. Based on CFD analysis and real-world results, the new design provides increased efficiency (>20%) with the possibility to position the outlet channel in any desired direction. Its features include: increased grit removal, low headloss, low power requirement and decreased carbon footprint.
