What is Grit Removal?
Grit removal is a crucial stage in wastewater treatment, responsible for separating dense, inorganic particles like sand, gravel, and stones from the incoming wastewater stream. These particles, referred to as grit, are heavier than organic matter and settle out quickly when the wastewater flow is slowed down.

This expanded document delves deeper into the Grit Mitt conveyor unit, breaking down the information into distinct chapters for clarity.
Chapter 1: Techniques
Grit removal techniques have evolved significantly over time. Early methods often relied on simple gravity settling basins, which were inefficient and prone to clogging. Modern techniques aim for higher efficiency and automation. Here's a breakdown of common approaches:
Gravity Settling: This fundamental technique relies on the difference in density between grit and organic matter. Wastewater flows slowly through a chamber, allowing grit to settle to the bottom. While simple, it's often insufficient for high-flow applications and requires large footprint.
Aerated Grit Chambers: Air is introduced to create a swirling, upward flow. This suspends lighter organic materials while heavier grit settles. This improves efficiency over simple gravity settling but still requires regular cleaning.
Hydro-cyclones: These use centrifugal force to separate grit. Wastewater is spun at high speed, causing denser particles to move outwards and collect at the bottom. They are compact and efficient but require significant energy input and can be sensitive to variations in flow.
Grit Mitt Conveyor System (WesTech): This innovative system utilizes a continuously moving conveyor belt with specialized buckets to collect and remove settled grit. Its unique design minimizes backflow and ensures consistent grit removal, even under varying flow conditions. The automated nature reduces manual intervention and enhances operational efficiency compared to traditional techniques.
Chapter 2: Models
Different models of grit removal systems are tailored to specific wastewater treatment plant needs, considering factors like flow rate, grit concentration, and available space. While the Grit Mitt itself doesn't come in various models in the same way a car would, the system can be customized to fit the specific requirements of each project. Key aspects of customization include:
