Features of Sludge Screw Press

Screw press sludge dewatering machine plays a crucial role in sludge management:

Efficient Dewatering

The machine employs a screw press mechanism that applies gradually increasing pressure and compression to the sludge. This results in effective water extraction, leading to high dewatering efficiency. It helps reduce the moisture content and the volume of sludge, resulting in lower transportation and disposal costs. Moreover, the machine can operate independently or multiple units work together.

Compact Design

The machine is designed with a compact structure, occupying small space so that it can easily work with existing wastewater treatment systems. Besides, the modular design makes it easy to install and maintain.

Continuous Operation

The machine operates continuously, allowing for a consistent and uninterrupted dewatering process for 24 hours. It can be automatic, with low maintenance and monitoring needed.

Versatile Application

The machine can handle various types of sludge waters, including municipal, industrial sludge, biogas slurry, etc. It is also widely used in pulp and paper industry, food processing, mining and mineral processing, and more.

Low Energy Consumption

The slow rotation speed of the screw press, typically ranging from 1 to 4 RPM. It requires lower energy consumption compared to high-speed centrifuges or belt filter presses, which helps to reduce operation costs.

Great Durability

The entire machine is built with 304 stainless steel, including the movable and fixed plates, screw press, flocculation mixing tank, metering tank, control box, casing and frame. Especially, the screw press and blades are wear-resistant and heat-treated to prolong its service life. And the entire machine is under a one-year warranty.

Benefits of Sludge Dewatering

Sludge dewatering machine will separate the water from the solid components of sludge, resulting in dewatered sludge with lower water content.

Reduced Volume

Dewatering significantly reduces the volume and weight of sludge, making it easier to transport and dispose of. The reduced volume also saves storage space, transportation costs and lower operational costs, including hauling fees and energy consumption.

Improved Sludge Handling

Dewatered sludge is easier to handle compared to wet sludge. The removal of excess water will reduce the risk of spills or leaks during transportation. Also, the drier solids can save further processing costs by requiring less energy and time for subsequent treatment or disposal.

Water Recycling

Through dewatering process, we will get relatively clean water that can be reused for various purposes. This reclaimed water can undergo further treatment to meet specific standards or be recycled for irrigation or flushing uses.

How Does Sudge Dewatering Screw Press Work?

In contrast to manure dewatering manure, sludge dewatering needs to add flocculant to the sludge before pumping it into the dewatering machine. Then the sludge is transported by the rotating screw along a cylindrical screen at a slow rotating speed (1-4 RPM). As the sludge moves through the press, the pressure and compression is gradually increase, effectively extracting water from the sludge. The water flows out through the screen and is collected, while the solid sludge particles are retained. The solids continue to move along the screw, gradually compacting into drier sludge cake, which is discharged at the end of the screw press. The water content of the dewatered sludge cake is about 75%.
