Environ engg offers clarifiers. Environ these clarifiers wide application areas includes are for chemical effluents, and various types of industrial and metallurgical processing. Efficient separation of suspended solids or sedimentation is an important and essential aspect in effluent treatment, since it not only reduces considerably suspended solids loading, but also helps in reducing the cod/bod loading, thereby contributing in reducing the sizing of subsequent process. The two basic types of clarifier mechanisms manufactured are end drive/traction drive type and centre-drive clarifier. The process is based purely of gravity-separation. This is achieved by the reduction in velocity of the fluid and nearly180° change in the direction of the flow. The separate solids would flow downward and settle on tapered floor. The slow moving scraper mechanism having scraper arms with neoprene rubber/pp/hdpe/brass squeegees, scrapes the floor and brings the settled sludge [suspended solids] to the central sludge well. The two basic types of clarifier mechanisms manufactured are end drive/traction drive type and centre-drive clarifier. There are two scraper arms in centre-drive type as compared to one scraper arm only in end drive type. So the floor is scraped twice in one revolution of centre-drive clarifier. Centre drive scraping is positive torque scraping, while in end drive, since the scraper is hung from the traveling bridge, the factors for the scraping force.
