Sub-vertical mechanical perforated screens for wastewater treatment
Optimize your wastewater treatment process with advanced fine screening technology that efficiently captures solids and reduces maintenance downtime, ensuring smooth operations even in challenging environments.

Screens and Filters Waste Water Efficiently
The GVS Sub-vertical Mechanical Perforated Screens, offered by WAMGROUP, are engineered for precise waste water screening across municipal and industrial facilities. Designed with a robust steel frame and perforated plate filters, these screens excel in capturing fine particulates through a chain-driven mechanism equipped with brushes and wipers. Ideal for applications in municipal waste water treatment plants, industrial waste water processing, and beverage industry waste management, they effectively handle water purification and sludge treatment, producing outcomes like treated municipal water and dewatered industrial sludge. With capabilities to process channel widths from 400 to 2,000 mm, the equipment maintains continuous automated operations powered by a motor with optional voltage and frequency settings. Constructed from materials such as hot dip galvanized steel and stainless steel (304L/316L), the screens offer durability and corrosion resistance. The unique design minimizes service needs, supporting easy component replacement and eliminating the requirement for a lower sprocket or bearings, which reduces maintenance interventions. Integrating seamlessly into your existing system, it offers adjustable angles up to 90 degrees, optimizing space and ensuring efficient installation and operation.
