Screw Press Sludge Dehydrator for Wastewater Treatment
Screw Press Introduction
Screw press with the advantage of high efficiency, low energy consumption, fully automatic control and stable operation. It can be directly and continuously reduced the water from the secondary settling tank, and the sludge after dewatering and separation is stable in the range of 70-85%. Lots ofwater is reparated by screw press and with the compact structure, thereby reducing capital investment and saving floor space, reducing the odor and phosphorus release from the sludge in the concentration tank, reducing the workload of subsequent sludge deeply dewatering, greatly improving the treating capacity of deeply dewatering equipments.
Screw Press Working Process
(1) The condtioned sludge flows into the filter chamber from the flocculation tank and is pushed forward the discharging end .
(2) With the gap between the thread of the shaft is getting higher and higher.
(3) Then the water is separated from the sludge and flows out from the gap between the movings and the fixed rings.
(4) The movement of the moving rings the fixed rings cleans the gap between them and prevent the machine from blockage.
(5) The filtered sludge cakes are pushed forward by the shaft and finally discharged from the end
Screw Press Features
(1) Simple process, high efficiency, power saving, low investment.
(2) Programme setting makes the operation convenient and accurte.
(3) Accurate chemical preparation and dosage saves much operation cost.
Screw Press Advantages
1. Small footprint: ECOPRO Sludge Dehydrator can be installed in places where placement would not be possible with other technology that makes ECOPRO Sludge Dehydrator suitable to cutomers who are considering the replacement of existing sludge dewatering unit.
2. No blocking: Due to the moving of the fixed rings and moving rings self-cleaning, the ubiquitous clogging is avoided, and it can handle oily sludge without trouble while separating the water from the sludge easily. Above all, no need large quantiry of flushing water and no odor, no secondary pollution during the sludge dewatering process.
3. Running cost saving: ECOPRO Multi-Disk Screw Press relies on the inner pressure of the filter chamber and the rotating speed is as slow as 2~4rpm. The average unit power consumption is only 0.1~0.01kwh/kg-DS(1/8 of Belt Filter Press and 1/20 of Centrifuge). Greatly reduce the running cost of wastewater treatment system.
4. Fully automatic control: ECOPRO Multi-Disk Screw Press equipped without the device like filter clothes or filter pore that is easily blocked. Operation is so easy and the device can be set to operate automatically via the eletric control cabinet.
