1.Description of reverse osmosis system soften water plant ion exchange water treatment

In the context of water purification, ion-exchange is a rapid and reversible process in which impurity ions present in the water are replaced by ions released by an ion-exchange resin. The impurity ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Positively-charged ions are called cations and are usually metals; negatively-charged ions are called anions and are usually non-metals).

1. Raw water pump-- provide the pressure to quartz sand filter/active carbon filter
2. Quartz sand filter-- get rid of turbidity, suspended matter, organic matter, colloid, ect.
3. Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter, ect.
4. Softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5. Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um,
6. High pressure pump-- Provide the high pressure to RO membrane
7. RO system-- main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions

The following ions are widely found in raw waters:

Cations	Anions
Calcium (Ca2+)	Chloride (Cl-)
Magnesium (Mg2+)	Bicarbonate (HCO3-)
Sodium (Na+)	Nitrate (NO3-)
Potassium (K+)	Carbonate (CO32-)
Iron (Fe2+)	Sulfate (SO42-)
