Circular Tank Scraper

Rotating Circular scrapers are designed to remove sludge and scum mainly in final settling tanks.

This sludge which has settled down at the bottom is collected by the scraper while floating solids on the surface are collected by the skimmer.

Features:

• low operational, maintenance costs and long lifetime components
• savings for concrete structures; thinner tank walls and bottom
• no need for massive center inlet structure, power supply only to outer tank wall
• flights are equipped with rubber blades to clean up tank bottom
