Water Purification

Water Purification

Adsorption
Activated carbon bonds with the chlorine and organic materials in feedwater to immobilize and remove these impurities.

Deionization
The removal of ions and minerals by synthetic ion exchange resins. Cation resins remove positively charged ions; anion resins remove negatively charged ions.

Distillation
The process in which water is heated to a gaseous state and recondensed in a separate vessel.

Filtration
Use as a pretreatment or a stand-alone treatment. Water passes through a filter of specified porosity at normal line pressures. The filter retains most particulates, with water passing through.

Reverse Osmosis
Use primarily as a pretreatment. Equal amounts of pure water and saline solution are separated in a U-tube by a semipermeable membrane. When external pressure is applied to the saline side, the semipermeable membrane allows water to pass through while salts are concentrated and flushed down
a drain.

Ultrafiltration
Use for removing pyrogens and bacteria. Under pressure, water is forced through a membrane with a pore size smaller than 0.005 ìm. Particulates are retained, with only pure water passing through.

Ultraviolet (UV) Oxidation
UV light (at <280 nm) passes through the water destroying bacteria, viruses, and trace organics.
