Overview

In 2021, Denis St. Pierre Water Pollution Control Plant, located at Lakeshore, Ontario started the upgrades of the existing screening and grit removal facilities to treat domestic water. For this project, Napier-Reid designed and supplied a Grit Removal System (GS-2), Napier-Reid’s Model VGS420.

The Vortex Grit Removal System is capable of removing sand and grit particles having a 2.65 specific gravity at a flow range of up to 51,400 m3/day, to a level equal to the spec required performance parameter. The grit removal system is comprised of a Vortex grit Tank, Access Bridge, and a mechanical agitator.

The full scope of supply includes an air blower equipment, one grit pump designed to pump slurries of grit, debris, and organic solids without clogging, one Cyclone (GCY-2), one Screw Grit Classifier (GC-2), and a control panel.
