Overview

The Grit King^® Process separates, cleans anddewaters grit from raw sewage and other liquids prior to delivering the grit to a skip ready for disposal. The Grit King^® Process consists of a Grit King^® Hydrodynamic Separator with backwashing system using air or water, a grit removal system (pump or gravity), a Grit-Cleanse™ or Grit Classifier and all connecting pipework. The Grit King^® Separator requires no external power source, as it uses the inherent energy of the influent with a headloss of typically less than 150 mm.

The Grit King^® Process incorporates the following stages:

• Grit King^® Separator

  The Grit King^® Separator is a hydrodynamic vortex separator which removes grit and sand from wastewater and other liquids. The dynamic separator is available either as a standalone vessel or internal components to be fitted into client's concrete chamber.

• Grit Removal - using one of two systems:

  • Pumped System - using a recessed impeller type.
    or
  • Gravity System - using a Knife Gate Valve with Hydro-Brake^® Flow Control

• Grit Classification - using one of the two alternatives:

  • Series 3 Grit Classifier
    A grit dewatering and classification device providing a consistent grit quality with low organics content, typically less than 15% residual faecal organics by weight.
    or
  • Grit-Cleanse™ (Series 4 Classifier)
    A grit dewatering and classification device providing a consistent grit quality with very low organics content, typically less than 5% residual faecal organics by weight.
• Interconnecting Pipework
• Local Control Panel (optional item)
