Sub-vertical mechanical bar screens for wastewater treatment
Optimize your wastewater treatment process by capturing coarse solids efficiently with sub-vertical mechanical bar screens, designed to enhance filtration and ensure continuous operation in demanding environments.

Screens and Removes Coarse Solids from Wastewater
The Sub-vertical Mechanical Bar Screens GVL from WAMGROUP is engineered to streamline coarse screening in municipal and industrial wastewater treatment facilities. Designed to address the rugged demand of environments such as abattoirs, food processing, and beverage industries, this equipment effectively captures solids with chain-driven rakes, transferring them to discharge points. The GVL screens use precision laser-cut raking tines and a stainless steel bar frame for enhanced durability and corrosion resistance. Operating with a 75-degree incline angle, they accommodate channel widths from 400 to 1,200 mm, ensuring efficiency in high-volume applications. Automation is seamless through a PLC-controlled setup, minimizing manual intervention and maintenance needs. Optional conductive level probes offer improved operational control, while integrated systems ensure quick and efficient serviceability without removing screens from their channels. Capable of reducing service requirements, GVL offers a cost-effective solution to handle wastewater challenges in diverse industries, supporting processes to produce treated effluents, sanitized food products, and more.
