Overview
The Grit King® Process separates, cleans and
dewaters 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 process
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:
- i) Pumped System - using
a recessed impeller type.
or
- ii) Gravity System - using a Knife Gate Valve with
Hydro-Brake® Flow
Control
- Grit Classification - using one of the two alternatives:
- i) 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
- ii) 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)
