9. Equipped with reliable backwashing equipment to ensure the dehydration effect of the filter belt.
10. Pneumatic tensioning and pneumatic automatic deviation correction devices are adopted to ensure the safe and normal operation of the filter belt.
11. The operation is safe and reliable, and infrared safety protection and all-round emergency safety parking devices are adopted.
12. Filter belts of different specifications and models can be configured according to different materials, with high filtration accuracy.

Efficiency: These machines optimize the dewatering process, resulting in higher throughput.
Cost-effectiveness: Reduced sludge volume reduces transportation and disposal costs.
Adaptability: Belt filter presses can handle a wide range of sludge types, making them suitable for different applications.
Belt filter presses are also known for their high capacity throughput, low initial cost, and low energy operating costs.

The operation of a belt filter press involves several key steps:
Sludge preparation: Conditioning the sludge with polymers to enhance the separation of water from solids.
Feeding: Prepared sludge enters the press and is sandwiched between two porous belts.
Squeezing: As the belts move, they apply mechanical pressure, forcing water out through the porous surface.
Collection: The result is a drier sludge cake ready for disposal or further processing.
This method is efficient and effective, producing a high solids content in the final product while saving energy.

Sludge management faces many challenges, including odor control, regulatory compliance, and the environmental impact of waste. Belt filter presses for sludge dewatering effectively address these issues. By reducing sludge volume, companies can reduce disposal costs and strengthen their sustainability initiatives.

Belt filter presses are mainly used for dewatering sludge and mud, etc. Belt filter presses are widely used in both municipal and industrial fields, including urban sewage and wastewater treatment, metallurgy and mining, steel plants, coal plants, breweries, printing and dyeing plants, tanneries, as well as chemical plants and paper mills.

Municipal sludge includes raw sludge, anaerobic digestion sludge and aerobic digestion sludge, alum sludge, lime softening sludge and river silt. In industry, any sludge or mud comes from food processing waste, pulp and paper waste, chemical sludge, pharmaceutical waste, industrial waste treatment sludge and petrochemical waste. These wastes can include mixed sludge, ore pulp, dust sediment, selected coal washing mud, biological sludge, primary sludge and straw, wood or waste paper pulp.

Some dewatering goals include reducing volume to reduce transportation and storage costs, removing liquids before landfill disposal, reducing fuel requirements before further drying or incineration, producing sufficient compost material, avoiding runoff and accumulation when used for land application, and optimizing other drying processes. Belt filter presses are specially designed for these specific applications and feed materials.

Based on the introduced advanced technology, DNY belt filter press is developed and designed based on DY belt filter press. DNY belt filter press is one ideal sludge-dewatering equipment which is widely used in chemical, coal, paper making, food staff, urban sewage and other industries. It also can be used as a liquid-solid separating machine. It features in high efficiency, good dewatering effects and low consumption. Using this kind of DNY belt filter press, no need of concentrating pond, thus saving the investment and floor area.

1.Slurry and potions go through the pipe to the conditioning tank.
2.The slurry after conditioning process then flow into the drum thickener, under the action of centrifugal force,the water in the slurry is screened.
3.Then the dehydrated slurry distribution to the filter belt, with the filter belt movement, the slurry on the filter belt affected gradually increased squeezing pressure,then the filter cake via number of S-type press roll crush , complete the cake dehydration.
