Product Description

Product Introduction

Sanshine Screw Press Sludge Dewatering Machine is an integrated industrial sludge treatment equipment designed for professional wastewater treatment plants and industrial manufacturing plants. It’s an advanced sludge dewatering equipment in the world. This equipment integrates a fully automatic control cabinet, the sludge thickening and dewatering machine body, and a collection tank. Under fully automatic operation, it can efficiently and stably remove moisture from sludge, reducing its volume and water content.

Product Application

Sanshine Screw Press Sludge Dewatering Machine is widely used in papermaking, printing and dyeing, textile, food processing, beverage, municipal, sewage treatment plant, livestock wastewater treatment, Slaughter wastewater treatment and other industries of wastewater treatment.

Product Principle

The gap between the moving ring and the fixed ring is designed to gradually narrow towards the sludge cake outlet. Due to the volume compression effect, the internal pressure of the filter element increases, thereby thickening and dewatering the sludge.
