A dewatering screw press, also known as a screw press dehydrator or screw press separator, is a device used for solid-liquid separation and dewatering of various materials. It is commonly used in industries such as wastewater treatment, food processing, pulp and paper, mining, and agriculture.
The GN screw press sludge dewatering machine represents an economically and environmentally friendly solution for sludge dewatering. Utilizing the principle of screw extrusion, this innovative equipment achieves solid-liquid separation by applying robust squeezing forces through the alteration of screw diameter and pitch, combined with the small gap between the floating ring and fixed ring.
Comprising a fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering device, as well as a liquid collecting tank, the GN dewatering screw press operates seamlessly. Its advanced automatic control technology enables fully automated flocculation, continuous sludge thickening and squeezing, and ultimately the discharge or return of the collected filtrate liquid.
The GN screw press dewatering machine finds extensive application in sewage treatment projects across various industries, including municipal, aquaculture, food, starch, oil, pharmaceutical, chemical, paper, leather, and more. Its versatility makes it an asset in efficiently handling sludge dewatering needs for different sectors and processes.
