Ion Exchange operates the tool.

In the double column process, the raw water first entered the field penulcar cation. Here sernua cations contained in the water (especially calcium ions, magnesium and sodium) exchange with hydrogen ions. Dalarn next column containing an anion exchanger, the anions (mainly chloride ions, sulphate and bicarbonate) exchanged with hydroxyl ions. Hydrogen ions from the cation exchanger and hydroxyl ions from the anion exchanger to form a bond and produce water.

After the water formed the ion exchange resins must be regenerated. Implementation of regeneration in double kolorn process is very simple. Into the cation exchange column asarn chloride flowed into the thin and anion exchanger columns streamed dilute sodium hydroxide solution. Excessive Regeneran further rinsed with water.

At the campfire mix - single column, cation exchange resins and anion exchanger mixed together in a single column. With the mix of fire can be achieved levels of water purity is much higher than with a double column process. In contrast, in the process of regeneration of resin mixture fire more complex exchange.

Working steps on fire regeneration mixture: Pernisahan cation exchange resins and anion exchange classification by using water (washing back from the bottom up). In this case the anion exchange resin that is lighter (much lighter color) will be above the cation exchange resin 349 is more severe (mostly darker). Washing should be held back until the two resin layers seen a sharp separation.

1. For regeneration, together with water regeneran channeled through two layers of dilute chloride resin acids derived from the bottom up through the cation exchange resin, and expelled from the column at the height of pernisah layer. Dilute sodium hydroxide solution flows from top to bottom through the anion exchange resin, was also issued at the height part of the separator layer.
2. Excess second regeneran then washed with water
3. Water surface elevation in the second column is derived and mixed exchange resins by compressed air entering from the bottom of the column.
4. Repeated washing with water pit mix from top to bottom, until the gauge shows the condition of the conductivity of the desired purity.

Now the installation is ready for operation again. Both the installation and the installation pclunakan water demineralisasi, then transfer from the operating conditions of the regeneration process, the implementation of their own regeneration, and pengalilian kembah to 350 operating conditions can be done either manually or automatic.

To achieve water quality or optimal performance and to prevent damage to the exchange resin, then the work instructions provided by the manufacturer of the installation (eg on the order of operations, the quantity and concentration regeneran, regeneration time and washing time) should be followed closely.

Caution: When working with Dain acid bases necessary for regeneration, personal safety equipment appropriate to be used. Waste water which came out in the regeneration can be acidic, alkaline or saline. and therefore in relation to environmental protection should be treated as chemical waste water.

The size of an installation performance ion exchange is the quantity of fluid produced per hour (or interval between two regeneration). Performance depends on the size or quantity instrument exchange, the quantity of ions to be separated (in terms of water purity has certain desired) and at the required level of purity. For the semi-continuous operation (when the water treatment bolch not stop in the middle) required two units are connected in parallel. Because the process of exchange and regeneration process can not take place at the same time, both units are working in turn, in exchange for one another when being regenerated.

Several types of exchange process is often combined together. For example to ease the burden of installing the main kolorn campfire mix (to improve perforinansinya) can be installed a water softener column in front of him.
