Grit Removal System

MAK Water is Australia’s most trusted supplier of water treatment, wastewater and sewage solution products. The Grit Removal System offers the same benefits as the Screen & Grit Removal Package but does not include any screening.

The Grit Removal System is designed to provide grit removal pre-treatment in a single packaged unit process. This machine has a flanged inlet for connection to pumped or gravity inflow, as well as a flanged outlet. Influent passes through a sedimentation tank, where heavy particles (sand and grit) settle to the bottom. Sand and grit are removed from the sedimentation tank via a system of screws. A horizontal shaftless grit conveying screw transports settled grit to the sump. Grit is then removed from the sump via a shafted extraction screw which lifts the grit from the tank for discharge into a bin. A blower can be installed as an option in the sedimentation tank to assist with fluidising the settled sand and grit. The blower can also provide classification for easier removal by the extraction screw. This compact system can also be configured to remove fats, oils and grease as an added option.

Using the influent TSS 500 mg/L with up to 0.5% grit as basis for the design reference, the typical performance of the ICrs has up to 90% removal efficiency for grit particles > 200 µm.

The ICrs is available in various treatment capacities ranging from 10 to 150 L/s.
