In the field of environmental protection,  the multi-disc screw press sludge dehydrator can be widely used in municipal sewage treatment engineering and water treatment systems in petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and other industries. Next, we will talk about the advantages of the multi-disc screw press sludge dehydrator.

With the miniaturization and distribution of sewage plants, the sludge produced by a single sewage plant is correspondingly reduced, so the traditional expensive and bulky equipment is not suitable for the rapid development of sewage treatment industry. At present, the typical process of sludge treatment in China is: sludge preconcentration tank -- mechanical concentration -- mechanical dehydration -- mud cake -- outward transportation. 

The research and development of the screw stacking sludge dehydrator is mainly to solve the problem of blockage. The tapered screw shaft with variable pitch is matched with the dynamic and static ring pieces. The rotation of the screw shaft drives the relative movement of the dynamic and static rings, completing the self-cleaning process when the equipment is running. The ring pieces are made of 304 stainless steel. The wear caused by friction is very small, so the equipment can run stably for more than ten years. 

The automation degree of the dehydrator is very high, so it can be operated unattended. The whole process of mud feeding, dosing, mixing, concentration and dehydration does not need workers to operate. Therefore, the sludge treatment of municipal sewage, leather, papermaking, printing and dyeing, pharmaceutical, winery and other industries all adopt the multi-disc screw press sludge dehydrator.
