Sludge with a water content of 80% that is discharged from a roller dehydrator, screw stacking machine, or centrifugal machine is sent to a screw conveyor and modifying mixer where a conditioner and modifier are added and blended. This results in the sludge being evenly delivered to the filter belt of a high-pressure belt-style sludge filter press through a distributor, and after a high-pressure continuous filter press is completed, press cake is formed with a water content of 60%. The process successfully achieves high-dry dewatering and meets environmental protection standards, making it an ideal sludge dewatering treatment machine. Technical features This treatment process works without a heat source, allowing direct dehydrating of various kinds of sludge to the desired moisture content even in cold conditions. A streamlined and highly automated layout; designed to provide maximum efficiency with minimal oversight. The entire procedure is odorless, silent, and releases no harmful fumes. It provides ideal work environment and has a positive impact on the surrounding environment. The conditioner doesn't alter the sludge's original qualities, and keeps the same amount of heat energy within. The installation plant can be built with minimal complexity and requiring a modest amount of capital investment. When the sludge fed into the sludge dewatering system from the thickener has a moisture range of 96-99% and an organic matter content not greater than 42%, the equipment will be in ideal functioning condition. However, the capacity and resultant moisture level of the sludge may vary depending on the initial moisture and organic matter present.
