Principle of operation, layout Filter systems are the main alternative for ESP systems discussed in the previous section. Gases (and also liquids) are separated from dispersed particles by passing it through a fabric or ceramic filter "medium" with a large surface area. Particles that...
Multimedia Filtration | MultiMedia Water Filters
Multimedia Filtration. Pressure vessels with sand or other loose media are widely used in industrial filtration applications. During the cleaning cycle, called "backwash", the bed is lifted (or "fluidized") to loosen the filter media and release trapped dirt which is removed in the backwash flow....
Pressure Filters Solid Liquid Separation
Pressure Filters, with the exception of the Rotary Drum Pressure Filter, are semicontinuous type machines that enter a wash and cake discharge mode at the end of the filtration cycle. The filtration cycle may extend from 510 minutes on cake filtration applications and up to 8 or even more hours for the polishing of liquids....

what should my filter pressure be? | Trouble Free Pool
Jul 06, 2019· A 10 PSI rise over a 10 PSI clean filter pressure is a doubling in return head loss which can dead head a pump. This is why one should use a relative rise (percentage) for determining when to clean a filter. On this forum, we have established a rise of 25% as reasonable filter rise for determining when to clean a filter....
