Sludge is an industrial waste generated during the municipal sewage treatment process. However, after drying, sludge can be converted into valuable resources, which can be used as soil conditioners or garden green fertilizer to provide organic matter and nutrients. It can also serve as an additive in brick and cement production or as raw material for ceramic lightweight aggregate. Due to its many drawbacks such as high moisture content, high viscosity, strong water retention, low calorific value, and high bacterial content, it is difficult to achieve industrial utilization. Therefore, high-temperature drying treatment is needed.

Dingli Company has conducted a series of technical research on the current market situation of sludge treatment and the characteristics of sludge in various regions. Dingli Company has focused its efforts to develop a new generation of sludge drum drying system. After drying, the product moisture content can be reduced to below 25%, meeting the standard for sludge sanitary landfill. This significantly reduces the content of bacteria and viruses, making it harmless and stable, and also enables further incineration treatment. The equipment technology is fully mature, with stable operating capacity, and operation and maintenance are also very convenient.

Zhengzhou Dingli is committed to developing this sludge dryer machine, and currently possesses mature technology and rich experience. If you are interested in learning more about our products, please feel free to call or email us to inquire about ordering.
