Microfiltration is a physical separation process. The extent to which turbidity and micro-organisms are removed is determined by the size of the pores in the membranes. When pressure driven fluid flows through a membrane micron sized particles separates from fluid and the process is called Microfiltration. Microfiltration is generally defined to be the filtering of a suspension containing colloids or fine particles in the approximate range of 0.1-10 micron. This size range contains a wide variety of natural and industrial particles such as, silt, viruses, bacteria, clay, colloidal silica, carbon black, paint pigment, yeast cells etc. Micro filtration is a pressure-dependent processes, where large particles get separated from smaller ones along with dissolved solids.

Ultrafiltration is a membrane process with the ability to separate molecules in solution on the basis of particle size. Ultrafiltration is typically rated by molecular weight cutoff. Ultra filtration can also be applied for pre-treatment of water for nano filtration or Reverse Osmosis. The pores of ultra filtration membranes can remove particles of 0.01 – 0.1 µm from fluids. Ultrafiltration (UF) membranes are able to separate colloids, suspended solids, emulsions, metal hydroxides, bacteria, viruses, emulsified oils, dispersed material and other large molecular weight materials from water and other solutions.

It is a solute-solvent separation process that uses a dense asymmetric semi-permeable membrane that is highly permeable to water and highly impermeable to solutes. A pressurized feed solution is passed over one surface of the membrane. As long as the applied pressure is greater than the osmotic pressure of the feed solution, “pure” water will flow from the more concentrated solution to the more dilute through membrane. RO membrane is widely used to remove salts from seawater or brackish water. RO membranes can remove solutes in the 0.0001 to 0.1 micron size range.
