1. Introduction
During the water treatment process , it will produce different kinds of moisture sludge. The sludge dewatering system is mainly used for reducing water content , moisture rate and sludge volume. This will bring convenience for next sludge treating process. Generally , the sludge dewatering system can be divided into belt press, plate-and-frame filter press , screw press. Currently , belt press has been widely applied in sludge dewatering process. Due to its large water consumption , high requirements of handling problems , screw press is a new kind of sludge dewatering system with energy conservation , stable and high automation.
2. Working Principle
The main body of screw press consists of several fixed rings and movable rings. The screw shaft runs through these rings, finally forming a filter unit. The former stage is thickening stage and the end is dewatering stage. Due its unique structure , it has replaced the traditional filter cloth and centrifugation.
- Simple treatment process , high efficiency of dewatering and thickening , low investment cost.
- Dosing with PAM agent for easy dewatering.
- High degree of automation , wide application.
- Continuous operation , no secondary pollution.
4. Application
It is widely used in municipal sewage , food , beverage , slaughter and breeding , printing and dyeing , petrochemical industry , paper-making , leather , pharmaceutical and other industries.
