while sewage sludge is usually treated using a standard plan of action it is extremely important to factor in aspects like the origin of the sewage the treatment process used to reduce the sewage to sludge as well as the possible byproducts that can be retrieved from it for further use before choosing a sludge treatment plan.
the pulau indah sewage treatment plant in malaysia uses heavy-duty pumps from grundfos to ensure efficient grundfos is part of the world’s second largest wastewater treatment plant 8 million people in downtown shanghai are served by the shanghai zhuyan 1 treatment plant where grundfos pumps are
the grundfos ranges of se/sl or s pumps with a vortex impeller can handle a dry matter concentration of up to 5% for the return pumping of sludge. variable speed drives (grundfos cue) can be added dependent on the specific control strategy at the treatment plant.

surface water treatment for potable supplies typically involves coagulation flocculation sedimentation and filtration processes for removing colloidal as well as suspended solids from raw water. all water treatment plants (wtps) produce waste/residue known as water treatment sludge (wts) during the purification of raw water.
the sludge which is found in the bottom of a sedimentation tank in water treatment plant is primarily composed of water. the solids in the sludge are mainly flocs excess coagulant such as alum. alum sludge has a solids concentration of only about 1 % when automatically removed from the basin or about 2% if manually removed.
