Applications
The DNT integrated belt sludge thickener and dewatering machine is designed for efficient thickening and dewatering of surplus sludge and mixed sludge from biochemical treatment processes in municipal wastewater plants. It is also suitable for sludge treatment across various industries such as manufacturing, leather, textile, chemical, and food processing.
Key Features
Stepless Speed Adjustment: Equipped with a motor drive that allows smooth and flexible speed regulation, offering strong adaptability to varying operating conditions.
Anti-Clogging Flushing System: Features specialized flushing nozzles and anti-clogging mechanisms to keep the filter belt clean and ensure continuous stable operation.
Efficient Dewatering Design: The dewatering head roller is designed with T-shaped drainage grooves, enabling rapid discharge of expressed water.
Enhanced Gravity Dewatering: The inclined gravity dewatering section increases the static head of the sludge, improving dewatering efficiency and enabling effective thickening prior to pressing.
Compact and Cost-Effective: The machine is designed with a compact structure, includes an automatic filter belt correction system, and operates with low noise, energy consumption, and chemical usage. It delivers excellent dewatering performance while reducing overall operating costs.

Structure and Working Principle
The equipment is mainly composed of belt thickener and dewatering machine. After adding coagulant, the sludge will flow into the gravity dewatering section after being fully mixed in the sludge mixer. Under the action of gravity, the sewage will flow into the gravity dewatering section. A large amount of free water in the mud flows out from the gap of the filter belt, enters the water collection tank, and then is guided by the wedge-shaped pre-compression section, so that the sludge is gradually leveled and slightly squeezed for further dehydration, and then enters the S-shaped multi-roller In the pressing section, the sludge is sandwiched between the upper and lower filter cloths and repeatedly squeezed by several spokes of different diameters. At this time, the sludge is sheared and the sludge is further dewatered to form a mud cake. Finally, the sludge is removed by a scraper. The cake is scraped off and transported out, and the upper and lower filter belts are washed and then reused.
