Particulate removal for a sludge treatment process

摘要: A system is described for producing small uniform pellets of predetermined size which are substantially free fines from mechanically dewatered sewage sludge and a means controlling odor the production said pellets. The includes process apparatus mixing with previously dried recycled particles sludge. Drying mixture in thermal drier, separating substantial portion solids drier off-gas. Clarifying separated to separate size, oversized pellets, undersized particles, crushing admixing crushed recycling incoming drier. off-gas mechanical separation then passed through two stage, series, high pressure cyclone remove all therefrom, without using wet scrubber. treated odors exhausted atmosphere.
