GNDL303 Screw Press for US Municipal Sludge Dewatering

The GNDL303 Screw Press is the ideal solution for municipal sludge dewatering in the United States. This state-of-the-art equipment combines efficiency, durability and compliance with industry standards for effective sludge treatment.

The GNDL303 Screw Press is manufactured from high quality 304 stainless steel to ensure corrosion resistance and long service life. Its robust design allows it to withstand the demanding operating conditions of municipal sludge treatment plants, reducing the need for frequent maintenance and extending operational life.

One of the key features of the GNDL303 Screw Press is the use of a variable frequency drive (VFD), which allows the operator to precisely control the speed of the screw. This flexibility allows the unit to adapt to different sludge consistencies and flow rates, minimising energy consumption while optimising the dewatering process.

In addition, the GNDL303 Screw Press is designed with PVC pipe connections in accordance with US standards. This standardised design facilitates seamless integration into existing pipework and ensures compliance with local regulations and codes. As a result, installation time and costs are minimised, while overall operational efficiency is improved.

Overall, the GNDL303 Screw Press provides an efficient and reliable solution for municipal sludge dewatering in the United States that meets the stringent requirements of the industry while providing long-term durability and performance.

GN disc stack separator

3-phase disc stack separator is an efficient solid-liquid separation equipment, widely used in chemical, petroleum, pharmaceutical, environmental protection and other fields. This separator adopts a unique disc design, through the high-speed rotation of the disc to generate a strong centrifugal force, the solid particles in the mixture of liquid and liquid separation.

The main working principle of the three-phase disc separator is: when the mixed liquid enters the separator, under the action of the high-speed rotating disc, the solid particles are thrown to the outer edge of the disc by centrifugal force and slid down along the disc under the action of gravity to the slag discharge; while the liquid, due to the difference in density and centrifugal force, forms a number of concentric rings inside the disc and is discharged from the central part of the liquid discharge port.

Three-phase disc separator has the following advantages:

High separation efficiency: due to the design of high-speed rotating discs, it can generate strong centrifugal force, thus achieving efficient solid-liquid separation.
Wide range of application: It is suitable for processing mixed liquids of various concentrations, viscosities and particle sizes, and is especially suitable for processing mixed liquids containing fine solid particles.
Easy to operate: compact structure, small footprint, easy to operate, easy to maintain and manage.
Energy-saving and environmental protection: there is no need to add any chemicals in the separation process, which reduces the operation cost and pollution to the environment.
It should be noted that when using the three-phase disc separator, you should choose the right model and specification according to the actual production demand, and operate and maintain it according to the operating procedures to ensure the normal operation and separation effect of the equipment.

Pls feel free to contac GN if any further question regarding 3-Phase disc stack separator.
