Alternative filtration methods
-Filtration is a process in which a turbid liquid (unfiltered liquid) is separated by a filter into a clear filtrate & a filtered residue or filter cake is left behind
- The driving force for this is always a pressure difference between the filter inlet & filter outlet
- The pressure at the inlet side is always greater than the pressure at the outlet side
- The greater the pressure difference the greater the resistance with which the filter opposes filtration
- It rises greatly towards the end of filtration
