Grit Classifier
Grittec is a grit classifier that separates rock, sand, and grit from screened wastewater. A large surface tank allows screened material to settle to the bottom, where a shaftless screw conveys screened debris to a dumpster.

Description
OPERATING MODE
The grit removal system operates by decantation to remove grit, sand, and rocks. Influent water flows slowly into the inlet hopper to allow grit to settle at the bottom of the tank. Then, captured grit is conveyed upward by the shaftless spiral. Effluent water evacuates through the top of the hopper to allow complete grit removal. A spray bar and cyclone system is optional.
Grittec can be installed in combination with our Hydrocyclone.
- Why It Wins
Features & Benefits
Efficient grit classification is achieved through the utilization of a tank that is both deep and wide.
Simple and Reliable Driving System
It consists of a pinion-and-rack system that is driven by a gear motor, causing the drum to rotate. This mechanism is constructed of HDPE (High Density Polyethylene) and does not require any maintenance.
To ensure stability during rotation, the drum is supported by oversized trunnions.
High Capture Rate
Drumtec effectively captures a wide variety of debris, including rocks, grits, organics, wipes, rags, fibers, and other materials. The perforated plate used in the system has a high capture rate, with the ability to screen materials as small as 800 microns.
This makes Drumtec an excellent solution for fine screening, particularly when used in conjunction with a MBR system.
Safe and Easy Access
Each side of the drum cover is equipped with a lift handle for easy opening. To assist with this process, a hydraulic mechanism is in place, allowing a single operator to safely open the cover.
Minimal Maintenance
Weekly maintenance of the system is minimal and only consists of visually inspecting the drum and the spray bar nozzles. If necessary, the nozzles can be easily removed for cleaning or replacement.
All-in-one equipment
To achieve a comprehensive screening treatment process, a built-in washer/compactor can be positioned directly at the discharge chute.
