Tube press Higher degree of separation

Tube Press The Tube Press is a membrane type filter press designed in cylindrical format and capable of o ­ perating at high filtration pressures up to 100 bar. • Where cake is to be disposed of to landfill The use of these high pressures enables a higher degree of separation of the liquid and solid phases. The process slurry is pumped into the annular space between the filter media and the bladder. Hydraulic fluid, usually water, is then pumped between the ­ ladder and the casb ing putting the slurry under pressures and Principle of operation Filtration takes place between two concentric cylinders....

complete the candle ­ loses to the slurry fill c position to repeat the cycle. ­ Air purge and/or cake wash can be incorporated into the cycle. At the completion of the ­ ltration element, air or wash fluid is fi pumped between the cake and the bladder which is then forced through the cake by a further application of hydraulic ­ ressure to ­ p be incorporated into the cycle. Benefits • Driest possible cake solids • Maximum volume reduction • Exceptionally clear filtrate Advantages of on-site tube press Tests will be undertaken on production s ­ lurry and will encounter any variability of p ­...

Mobile test plant rig Superior performance Laboratory and rental service Porosity and cake moisture contents are s ­ ignificantly lower than those obtained with low pressure filters, consequently filtrate recovery is high. Filtration is conducted at a pressure level where the cake is produced as a hard surface dry, lump solid. Cake handling procedures are greatly ­ implified compared with those s for low pressure filter cakes, which are typically plastic or paste-like and frequently surface wet. Metso can filter your product on both a p ­ reliminary feasibility or on a full-scale p ­ roduction...
