Sub-vertical perforated screens for wastewater treatment
Optimize your wastewater treatment with robust mechanical screening, reducing maintenance and ensuring efficient removal of solids from a variety of industrial and municipal effluents.

Captures and Cleans Wastewater Solids Efficiently
The GVS Sub-vertical Mechanical Perforated Screens from WAMGROUP offer an efficient solution for fine screening in municipal and industrial wastewater treatment facilities. Designed with a robust steel frame and customizable perforated plate filters, these screens excel in capturing solids from diverse effluent streams. The chain-driven system utilizes brushes and wiper blades to maintain clean filters, ensuring seamless operation and minimal maintenance disruptions. Applicable across industries such as beverage production, food processing, and pulp manufacturing, the GVS Screens promote treated and recycled water, refined solids, and compostable by-products. With channel widths spanning 400 to 2,000 mm and incline angles adjustable from 75 degrees to vertical, they integrate simply into existing infrastructures. Built from hot dip galvanized or stainless steel (304L/316L), these screens resist corrosion while meeting strict environmental compliance standards. Effortless blade and wiper replacements minimize downtime, making this equipment a versatile and reliable choice for diverse waste management applications.
