Grit wash unit

Product catalog summary

Overview: The FSM grit wash unit is designed for high-performance separation of fine grit particles in water and wastewater treatment. It aims to meet the TA Siedlungsabfall standards for waste deposition and is available in both dry and wet charged versions.

Components: The unit consists of a grit wash tank and a discharge screw. It can operate without a screening drum depending on the inlet screening unit's effectiveness. The design emphasizes low water consumption and low operating costs.

Functional Principle: The grit/water mixture enters through the inlet flange. Organic matter is suspended and floated off, while grit sediments in the tank. Water addition helps separate grit from organic matter using a stirring device and up-current technique. The grit is then de-watered and discharged.

Features:

Robust construction ensures high reliability.
Compatible with upstream coarse screens.
Uses service water free of COD and BOD as wash water.
Can be mounted on a skimmer for additional wash water supply.
Reduces organic content to volatile solids below 3%.
Expandable to handle sewer grit and street sweepings.
Handles up to 30 l/s.
Available in dry charging versions for compact installations and retrofitting.
Low maintenance and excellent cost/performance ratio.
Suitable for outdoor and winter operations.
Hygienically encapsulated for safety.

FSM Grit wash unit The FSM grit wash unit has been developed with three aims in mind: 1. To achieve a very high finest grit particles 2. To achieve the limit value called SledlungsaPfall (residential Class 1 dumping site with upstream coarse screen. 3. Grit wash unit In dry and wet charged versions. The FSM grit wash unit consists of two basic items - grit wash tank and discharge screw. Depending upon the effectiveness of the iniet scree- ning unit the screening drum can be dispensed with.
