Ultrafiltration a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and... |
Microfiltration a type of physical filtration process where a contaminated fluid is passed through a special pore-sized membrane to separate microorganisms and suspended particles from process liquid. The operational pressure is 0.01-0.1 MPa. The microfiltration membrane... |
Reverse osmosis a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from water. In reverse osmosis, an applied pressure (1-10MPa) is used to overcome osmotic pressure, a colligative property, that is driven b... |
Nanofiltration a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors ... |
Flocculation a process where in colloids come out of suspension in the form of floc or flake; either spontaneously or due to the addition of a clarifying agent. |
