Ion Exchange Water Treatment System Pdf

If the ph of water is 10 or higher the lead can found as a plumbate.

Ion exchange water treatment system pdf.

In an ion exchange system undesirable ions in the water supply are replaced with more acceptable ions. A typical water treatment plant consists of the following sections. The hardness ions ca and mg move into the resin beads and each of these divalent. The softener contains a microporous exchange resin.

Sodium ions are supplied from dissolved sodium chloride salt also called brine. Removal of organics is not complete as shown by the significant proportion of bod organic carbon etc remaining in the product. Impurities removed include suspended. Household water softeners are ion exchange devices.

It removes impurities that are likely to affect the pr performance of downstream units based on ion exchange and or membrane and thermal processes. This type of lead has a negative. Effect of ion exchange treatment. This type of lead must be physically filtered and may require the use of a submicron filter.

Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes. The ion exchange water treatment systems also include state of the art plc based or digital stager regeneration controls to assure consistency and reliability. 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.

Standard water softeners are cation exchange devices. Treatment of water for human consumption. Ion exchange systems are used for efficient removal of dissolved ions from water. 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.

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. Rohm and haas ion exchange ion exchange introduction 4 fd sep 2008 to soften water you take a cation exchange resin on which the mobile ion inside the beads is sodium na and you pass the hard water through a column filled with the sodium form resin. Filters that remove chemicals often do not effectively remove germs and vice versa. Some water treatment devices that remove chemicals such as reverse osmosis ion exchange or distillation systems might also remove fluoride.

Designs and manufactures both standard and specially engineered ion exchange water filter equipment for an array of applications including deionization. Cation exchange involves the replacement of the hardness ions with a nonhardness ion.
