DL Stacked-screw Sludge Dewatering
DL Stacked-screw Sludge Dewatering which uses the screw extrusion priciple is a new type of solide-liquid separation device. It reaches the goal of extrusion dewatering sludge by the powerful extrusion pressure of changing the screw diameter and distance along with the tiny spacing between moveable and fixed annular plates.


★The main body of screw filter press is made of multiple fixedannular plates and moveable annular plates with the screw shaftrunning through it.★The front part is concentrating section and the ending part isdewatering section. It can concentrate and dewater sludge inone chamber.★Sludge will be transported to the dewatering part after beingconcentrated in the thickening section.★ln the advancing process, great pressure has been producedbecause of the gradually decreasing filter spacing and screwdistance with the block of the back platen. Then the volumedecrease continuously, and the purpose of fully dewatering willbe achieved.

The main function of the Industrial Waste Water Treatment Machinery is to dewater and thicken sludge through a screw extrusion process, effectively separating solids from liquids.
The DL Stacked-screw Sludge Dewatering system operates by using screw extrusion principles, where sludge is concentrated and dewatered in a single chamber by applying powerful extrusion pressure through varying screw diameters and spacing.
This machinery can process any type of sludge, including those rich in oil and grease, making it highly versatile for various industrial applications.
Benefits include low energy and water consumption, minimal noise, low polymer usage, no need for sludge thickening, low maintenance costs, and the ability to operate continuously.
The maximum dry sludge treatment capacity varies by model, with capacities ranging from 130 kg-Ds/hr to 450 kg-Ds/hr depending on the specific model chosen.
Dimensions and weights vary by model. For example, the DL-131 model has dimensions of 600mm x 1200mm x 200mm and a total weight of 300 kg, while the DL-404 model has dimensions of 2500mm x 2100mm x 450mm and a total weight of 750 kg.
Yes, the equipment is designed to work continuously 24/7, making it ideal for industrial applications requiring constant sludge processing.
The dewatering equipment requires minimal maintenance, which typically includes regular inspections and occasional cleaning to ensure optimal performance.
This equipment offers advantages such as lower energy and water consumption, reduced operational costs, and the ability to handle a wider variety of sludge types compared to traditional methods.
Motor power requirements for the machines range from 1.1 kW to 7.5 kW, depending on the model and its specific capacity.
Yes, the DL Stacked-screw Sludge Dewatering equipment is specifically designed to handle oil and grease-rich sludge effectively.
The machinery operates at a minimal noise level, making it suitable for environments where noise reduction is a priority.
The installation process typically involves positioning the unit in a suitable location, connecting it to the sludge source and power supply, and conducting a system check to ensure proper operation.
Additional costs may include installation, periodic maintenance, and consumables like polymers, but the equipment is designed to minimize ongoing operational expenses.
Choosing the right model depends on your specific sludge treatment capacity needs and the characteristics of the sludge being processed. Consulting with a sales representative can help determine the best fit.
