Product Q&A

Q:What is the self-cleaning mechanism of this machine?

The rotation of the screw shaft promotes the continuous rotation of the swimming ring. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby avoiding common plugging problems.

Q:What industries can this sludge dewatering machine be used for?

It is widely used in municipal sewage treatment, petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather, food, beverage, and printing and dyeing industries.

Q:Does the machine require a concentration tank for low-concentration sludge?

No. When dehydrating sludge at a low concentration (2000 mg/L), there is no need to build a concentration tank or storage tank, which reduces construction costs and minimizes anaerobic odors.

Q:What is the discharge concentration of the filter cake?

The machine can achieve a discharge concentration of 30-45% for the sludge filter cake.

Q:What materials is the machine body made of?

The body is made of stainless steel almost entirely, which maximizes the service life of the equipment.
