As a rotating bridge scraper manufacturer and a worldwide rotating bridge scraper supplier, Vortex Engineering provides large variety of design options.
Rotating bridge scrapers installed in circular sedimentation tanks are designed to scrape the settled sludge and floated scum in the clarifier, thus reducing suspended solids content in the water.
According to the customer needs the bridge can be manufactured as semi, extended or full bridge type.
In circular tanks flow pattern is radial. To achieve a radial flow pattern, the wastewater to be settled is introduced from the center of the tank. Settleable solids are settled to the bottom while the scum is floated on the surface of the water through sedimentation.
Bottom scrapers of the continuously rotating bridge collect the settled sludge into a hopper at the center while surface scrapers collect the scum into a scum hopper.
