Other processes are also used to purify water, including reverse osmosis, carbon filtration, microporous filtration, ultrafiltration, ultraviolet oxidation, or electrodialysis.

USA created Purelux the first residential under-the-sink water purification system combining ultraviolet (UV) light and activated carbon filtration.

Following fermentation, it undergoes a single pass through a four-column continuous distillation and traditional carbon filtration.

Dechlorination can be accomplished by carbon filtration, or the use of sodium thiosulfate.

Where chlorine and chloramines are found in the water, carbon filtration is needed before the membrane, as the common residential membrane used by reef keepers does not cope with these compounds.

Tap water can be dechlorinated by deionization, carbon filtration, or the use of sodium thiosulfate.

Some communities, such as Iowa City resort to additional carbon filtration and lime softening coagulation-sedimentation to make the water more palatable.

Mr. Granger said that M.T.B.E. removal required carbon filtration as well as an air-stripping treatment at the wellhead that is more extensive than the process now used to remove organic compounds.

CLCJAWA draws water from Lake Michigan and purifies it with several water treatment processes including ozone, coagulation, flocculation, activated carbon filtration, ultraviolet light and chlorination.

Historians have shown evidence that carbon filtration may have been used in ancient Egyptian cultures for both air and water sanitization.
