Grit and Grease Removal System

Efficient, low maintenance grit and grease extractor

The AERODREDGE* Grit and Grease Removal System is designed to reduce horizontal flow velocity to allow heavy particles to settle while grease and other floating substances are allowed to rise to the surface to be separated. An aeration system is utilized to keep the majority of organic materials in suspension during this process. Slower spiral flows at the effluent end allows grease to float to the top of the unit for easy removal.

Overview

Grit & Grease Removal Technology

The AERODREDGE Grit and Grease Removal System is a proven and efficient grit and grease extractor. The air mixing and tank equipment adjust to treat significant variations in horizontal flow velocity. Horizontal flow velocity is reduced to allow heavy particles to settle while grease and other floating substances are allowed to rise to the surface to be separated. An aeration system is utilized to keep the majority of organic materials in suspension during this process. All moving parts are accessible from the bridge or the walls of the grit tank.

Features & Advantages

Low Maintenance Grit and Grease Removal

The AERODREDGE is a low maintenance, automated and reliable technology to protect downstream processes

  • Grit removal: minimizes abrasion of mechanical equipment and minimizes grit/sand accumulation downstream.

  • Grease separation: removes grease & scum prior to biological and sludge treatment.

Advantages

  • Layout – Retrofitting: Appropriate for new construction and can be retrofit into most existing basins. 

  • Reliability: A proven technology with over 100 installations worldwide. Exceptional tracking and alignment.

  • Redundancy: A single grit pump is standard, optional duplicate pump

  • Simple Control System

  • Heavy-Duty Construction: Cog-wheel drive of hardened steel components.

  • Operator Attention: Automated system requires little maintenance from plant personnel.
