Rectification Grating

The UV disinfection system is equipped with a rectification grating to intercept floating objects, water plants and garbage from entering the disinfection channel, to prevent debris from winding around the lamp casing of the rack and to avoid the fracture of the lamp casing caused by uneven forces during cleaning, and to distribute the incoming water to ensure an even and stable flow pattern and to protect the lamp from damage by impact.

Water level control system

The water level control system adopts a non-powered top self-flowing fixed weir, installed at the rear end of the UV module, for controlling the water level.

Rectification Grating
