MULTI-DISK SCREW PRESS
FOR SOLID-LIQUID SEPARATION
Multi Disc Screw
Press Technology–A New Age Solid
Liquid Separation
The technology evolved into the mainstream since the first decade of 2000.The multi disc screw press uses the torque and force accumulated by the gear box transmitting to a centrally driven tapering screw surrounded by alternating fixed and moving discs spaced 200micron apart.This squeezing action along with addition of flocculant in case of Sludge,provides a straining action for the solid and liquid.Moreover,the discs are self cleaning and with each rotation of the screw,all moving discs are displaced from its location again moving back to the same position after each rotation.
Typical sludge dewatering Process From Generation To Disposal
Key Parts and Features
Flocculation
Floc formation is carried out by surface charge stabilization with the help of polyelectrolyte as per sludge characteristics by trial with different polyelectrolytes.This operation takes pace in the flocculation tank of the screw press supported by the paddle type agitator at 4-8RPM
Thickening:
After flocs are formed the affinity of solids with the water reduces and a significant portion of water is separated though the gap between discs by draining action.This operation takes place in the thickening zone i.e.the initial 50%of the screw length
Dewatering
The thickened sludge is now displaced gradually toward the tapering end of the screw,which pushes the thickened sludge towards the pressure plate to squeeze out the remaining moisture so that the cake dropped is of >20-21%w/w consistency
Filtrate Recycling
The filtrate is then recycled to the collection tank by gravity or by pumping
Multi Disc Screw Press vs Centrifuge vs Filter Press typical case of 10cum/hr feed flow @ 2%solids w/w
| Parameter | Multi Disc Screw Press | Centrifuge Decanter | PP Filter Press |
| Power Consumption | 1kW * | 20kW ***** | 5kW *** |
| Maintenance-Mechanical | Operated at only 4RPM with almost zero wear tear;Complete built is in SS 304/316 * | Operated at only 4000RPM with high chances of major wear tear;Only water contact parts are in SS and rest is in MSEP ***** | Replacement of cloth due to clogging.Build is generally MSEP thus high corrosion potential ** |
| Moisture Content of Sludge Dewatered | 20-25%w/w * | 18-20%w/w * | 20-25%w/w * |
| CAPEX | 10%higher than owning a centrifuge or filter press *** | Highest cost in the category ***** | Lowest cost ** |
| Recurring CAPEX | Almost zero * | Very High due to vibrations and bearing replacement ***** | Medium mostly requires replacement of filter cloth *** |
| Chemical Cost | 50%of that from centrifuge when processing biological sludge ** | Highest requirement of polyelectrolyte ***** | Almost same as the Screw Press ** |
| Noise Vibrations | No noise and vibrations as all moving parts are at low RPM * | Very high noise level ***** | No Noise as no moving parts except the feed pump * |
| Labor Cost | No labor cost of manual handing of sludge as it is * | No labor cost of manual handling of sludge as it is in continuous application * | Very high labor intensive due to cleaning of cloth and changing the cloth ***** |
