SIDE-DRIVEN CIRCULAR SCRAPERS

GENERAL DESCRIPTION AND INTENDED USE

Circular scrapers are used in the settling pools in the chemical and biological wastewater treatment facilities. They are designed to be used in pre-settling and final settling pools in biological treatment facilities. They are used to scrap the sludge and floating materials in the wastewater. Sludge settled at the bottom of the pool under laminar flow conditions are gathered at the center of the pool with the aim of circular scraper. At the same time, floating materials are scrapped with the help of surface scraper and removed from the system. The wastewater at the clear stage leaves the system through pool floodgate.
