FIELD: process engineering.
SUBSTANCE: invention relates to treatment of effluents in radial settlers by withdrawing insoluble substance suspended particles from effluents, and may be used at effluents aeration stations, etc. Bulk of removed sediment the main scraper approaches is pre-separated into portions, each to be displaced separately to form therefrom a drag prism to be placed into ooze pit.
EFFECT: power savings in shifting ooze sediment into pit.
