ETP stands for Effluent Treatment Plant, is one type of wastewater treatment process which is basically designed to treat domestic and industrial wastewater and other types of sewage. Sludge is the semi-solid slurry of waste that settles at the bottom of ETP, and that slurry is brought out of the system for treatment or disposal. That slurry from ETP is known as ETP sludge. Sludge exists in a solid or semi-solid state as a byproduct of wastewater treatment, sewage treatment, and water treatment. 

  Sludge contains about 70% water and usually needs to be dewatered and dried before final disposal. Sludge drum dryers are the most common way to dry sludge. ETP sludge dryer provide for drying is the simplest method of dewatering sludge. During this process, the ETP sludge continuously exchanges heat with the hot air under the rotation of the drum, and the built-in paddles break up the sludge to increase the heat exchange area. The sludge drum dryer has large processing capacity, advanced technology and high efficiency. After treated, sludge can be used as supplementary energy resources, used for agriculture, landscaping, control soil erosion, ceramic manufacturing, etc.
