Ion Exchange Water Treatment System Pdf

Cations refer to positively charged ions dissolved in the water.

Ion exchange water treatment system pdf.

Ion exchangers exchange one ion for another hold it temporarily and then release it to a regenerant solution. Water softeners usually use sodium na as the exchange ion. In an ion exchange system undesirable ions in the water supply are replaced with more acceptable ions. Removal of organics is not complete as shown by the significant proportion of bod organic carbon etc remaining in the product.

Cation exchange involves the replacement of the hardness ions with a nonhardness ion. Designs and manufactures both standard and specially engineered ion exchange water filter equipment for an array of applications including deionization. A typical water treatment plant consists of the following sections. If the ph of water is 10 or higher the lead can found as a plumbate.

Household water softeners are ion exchange devices. Some water treatment devices that remove chemicals such as reverse osmosis ion exchange or distillation systems might also remove fluoride. Children who drink water with levels of fluoride 0 6 ppm might need a fluoride supplement. The softener contains a microporous exchange resin.

Ion exchange systems are used for efficient removal of dissolved ions from water. 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. 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.

Sodium ions are supplied from dissolved sodium chloride salt also called brine. It removes impurities that are likely to affect the pr performance of downstream units based on ion exchange and or membrane and thermal processes. 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. Standard water softeners are cation exchange devices.

Impurities removed include suspended. The hardness ions ca and mg move into the resin beads and each of these divalent. Treatment of water for human consumption. Effect of ion exchange treatment.

Filters that remove chemicals often do not effectively remove germs and vice versa. Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes.
