Powdered lime is stored in 25 kg bags or in a silo, depending on the size of the installation. In France, the preferred minimum silo capacity is 50 m³, this being the maximum lorry payload (25 tonnes). The base of the silos is equipped with a flow assister. Mechanical flow assisters are usually preferred over fluidisation air injecti…See more on suezwaterhandbook

Activated carbon can be decompacted by installing an "intermediate hopper". A transfer screw or a rotary vane feeder feeds the hopper. The feeding system is mounted on the "intermediate hopper". Once the PAC has been decompacted, a volumetric feeding (screw-type feeder) then becomes feasible. PAC is a product having a widely varying density ...

Executive Summary. Mechanical dewatering is normally associated with large wastewater treatment plants and is used to separate sludge (residual sludge from wastewater treatment plants or faecal sludge from on-site sanitation) into a liquid and a solid part. The principal methods are belt filter presses, centrifuges and chamber filter presses.
