Sub-vertical mechanical bar screens for wastewater treatment
In both municipal and industrial wastewater treatment facilities, coarse screening is essential to remove large solids from the water before it undergoes further treatment. These screenings help prevent blockages and reduce the load on downstream processes.
Efficient solids removal with minimal maintenance
The GVL Mechanical Bar Screen by WAMGROUP is designed for coarse screening in wastewater treatment plants. This screen consists of a durable steel frame and a customizable bar filter, with bar spacing ranging from 10mm to 40mm, according to the required screening efficiency. The system uses highly resistant galvanized steel chains for the transmission shaft and upper sprocket. The filtration zone features individually replaceable bar sections, ensuring longevity and easy maintenance. Wastewater flows through the unit, where solids are captured on the bars. Chain-driven rakes clean the bars, conveying solids to the discharge point where they are removed and deposited into a dumpster, conveyor, or compactor. The GVL screen includes features such as recessed guide channels for drive chains, eliminating the need for lower sprockets and bearings, which significantly reduces service requirements. It is ideal for applications in municipal and industrial wastewater plants, including those in the food processing, pulp and paper, and livestock breeding industries.
