Ion Exchange Water Treatment System Pdf

Sodium ions are supplied from dissolved sodium chloride salt also called brine.

Ion exchange water treatment system pdf. It removes impurities that are likely to affect the pr performance of downstream units based on ion exchange and or membrane and thermal processes. Cation exchange involves the replacement of the hardness ions with a nonhardness ion. A typical water treatment plant consists of the following sections. Some water treatment devices that remove chemicals such as reverse osmosis ion exchange or distillation systems might also remove fluoride.

The softener contains a microporous exchange resin. If the ph of water is 10 or higher the lead can found as a plumbate. While the chemistry of individual ion exchange reactions varies from one application to the next ix is a treatment process where dissolved ions are replaced by other more desirable ions of a similar electrical charge. Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes.

Designs and manufactures both standard and specially engineered ion exchange water filter equipment for an array of applications including deionization. Effect of ion exchange treatment. In an ion exchange system undesirable ions in the water supply are replaced with more acceptable ions. Filters that remove chemicals often do not effectively remove germs and vice versa.

Water softeners usually use sodium na as the exchange ion. Ion exchange systems are used for efficient removal of dissolved ions from water. Impurities removed include suspended. Removal of organics is not complete as shown by the significant proportion of bod organic carbon etc remaining in the product.

This type of lead must be physically filtered and may require the use of a submicron filter. If the ph of water is above seven lead may be in a precipitated non ionic colloidal form which cannot be removed by an ion exchange process. The ion exchange water treatment systems also include state of the art plc based or digital stager regeneration controls to assure consistency and reliability. Standard water softeners are cation exchange devices.

Cations refer to positively charged ions dissolved in the water. Children who drink water with levels of fluoride 0 6 ppm might need a fluoride supplement. This type of lead has a negative. Ion exchange involves removing the hardness ions calcium and magnesium and replacing them with non hardness ions typically sodium supplied by dissolved sodium chloride salt or brine.

Treatment of water for human consumption. The hardness ions ca and mg move into the resin beads and each of these divalent.
