(1) Vortex grit removal systems have a consistent removal efficiency over a wide flow range. (2) There are no submerged bearings or parts that require maintenance. (3) The "footprint" (horizontal dimension) of a vortex grit removal system is small relative to other grit removal systems, making it advantageous when space is an issue.

Sludge Trap - Sand Trap - AZU Water

Vortex grit chamber is the most innovative sand trap: wastewater enters tangentially and creates a vortex current. Under the influence of centrifugal force and gravity, grit and other solids quickly collect to the centre of the grit chamber It requires lower areas and low residence times but it can not be associated with oil removal.

Vortex Separators Provide Various Options in Grit Removal ...

The key to choosing an optimized grit removal system is to know the gradation of grit for the locality as well as the average daily flow and the peak wet weather flow for the treatment plant. Economics are always a factor for municipalities and regional wastewater treatment plants, so plant operators are increasingly cognizant of their options.

Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

Characterizing hydrocyclone performance for grit removal ...

The purpose of this study was to verify the feasibility of selectively separating grit from wastewater activated sludge by hydrocycloning and to develop methods for characterizing the hydrocyclone's grit removal performance from wastewater activated sludge based on concepts similar to those used in mining engineering.
