Process of Sludge treatment by dehydration and drying

Dewatered sewage sludge from wastewater treatment plants is encountering increasing problems associated with its disposal. Sludge drying is an intermediate sludge treatment process that consists of evaporating the water in the sludge. Sludge drying is the process of transforming sludge into useful products or green fuel. Removal of water reduces storage volume and transportation costs. Thermal drying is used to achieve up to 80% volume reduction and up to 90% weight reduction. It significantly reduces the volume and weight of the sludge so that it is easier to recover.

Sludge is the industrial waste generated during the production process of municipal sewage processing. Because sludge has many disadvantages such as high moisture content, high viscosity, high water holding capacity, and low calorific value. It is difficult to achieve industrial utilization. Aiming at the current market situation of sludge treatment and the characteristics of sludge in various places, Dingli has carried out technical research and practice many times and meticulously created a new generation of sludge drum drying system. The moisture content of the dried product is less than 25%, which reaches the sludge landfill standard or Conditions for further incineration.

Dingli new type sludge dryer  internal structure strengthens the cleaning and heat conduction of the dispersed material, eliminates the sticking phenomenon of the inner wall of the cylinder, and has stronger adaptability to moisture and viscosity of the material. By using the unique bulk sludge delay drying technology to ensure the uniformity of the slime drying.

Dingli sludge drying machine has a strong capacity against overload, the capacity of dealing with large amounts of processing, less fuel consumption, and low drying cost. The technology of equipment gets absolutely mature enough, also it has a stable capacity of operation and very convenient to operate and maintain. For more information, welcome online consultation.
