Filter & Strainery

The Alfa Laval rotary drum filter Aldrum G3 sets a new standard for sludge thickening. The sludge thickener efficiently thickens sludge to optimize downstream processes, boosting biogas production and reducing dewatering costs. Its enhanced design, featuring a rotary drum filter and an efficient sludge hopper, improves performance while keeping operating costs low.

Using gravity to thicken dilute sludge and slurries, the Alfa Laval AS-H belt thickener is suitable for all municipal or industrial flocculated sludges – particularly those from biological and activated sludge processes. Low energy and polymer consumption and trouble-free operation give important reductions in both cost and hassle for wastewater management.
