  • How to Treat and Dispose Sludge? Waste Management

    The vacuum holds the sludge against the drum as it continues to be applied as the drum rotates out of the sludge tank. This pulls water away from the sludge leaving a moist cake mat on the outer surface. The sludge cake on the filter medium is scraped from the drum just before it enters the sludge
