    How do Deionized Water Tanks Function?

    The working principle behind deionized water tanks is founded on the process of ion exchange. Essentially, the raw water is subjected to sediment filters to eradicate debris and occasionally activated carbon filters to get rid of organics. Consequently, the water is injected into a DI exchange tank filled with cation exchange resin which swaps the positive objectionable ions with Hydrogen (H+) ions.

    Subsequently, the resulting water is injected into an anion DI tank which replaces the objectionable negative ions with Hydroxyl (OH-). For improved quality, the deionized water from the two-bed DI water tank is injected into a mixed-bed deionization system which acts as a polishing process. Here is a visual explanation of the ion exchange process.

    Back to the guide ⇪

    What is the Composition of Ion-Exchange Resins?

    First, ion exchange is a rescindable chemical process that replaces undesirable ionic contaminants in water with non-objectionable ions. Ion exchange resins on the other hand are physical mediums that enable the deionization processes. Typically, ion exchange resins are made from organic polymers which combine to create hydrocarbons.

    The polymer medium is then filled with ion-exchange sites that harbor the non-objectionable cations and anions (functional groups). In two-bed ion exchange systems, the cation and anion ion exchange resins are contained in distinct DI water tanks. In mixed-bed deionizers, the cation and anion resin beads are rigorously blended in a single DI water tank.

    Which Pollutants are Eradicated by Deionized Water Tanks?

    Water deionizer machines are purposely manufactured to eradicate minerals and charged constituents from water. They typically eradicate a diverse range of pollutants since most water contaminants are charged dissolved inorganics.

    Deionized water tanks primarily remove cationic and anionic impurities using separate or blended anionic and cationic exchange resins. Consequently, they shrink water hardness by eradicating calcium and magnesium ions. Other contaminants removed include:

    Cation exchange resins

    Calcium (Ca2+)

    Anion exchange resins.

    Chloride (Cl-).

    Magnesium (Mg2+) Bicarbonate (HCO3-).
    Sodium (Na+) Nitrate (NO3-).
    Potassium (K+) Carbonate (CO3-).
    Iron (Fe2+) Sulfate (SO4-).

    Back to the guide ⇪

    How are Deionized Water Systems Used in Water Softening?

    Water hardness is a common attribute of raw water from distinct sources. Using hard water in domestic applications and industrial processing often results in precipitation that ultimately causes scaling or nullifies the effects of soap. To counteract the negative implications of hard water, a water softening process (mainly ion exchange) is deployed.

    Technically, the ions responsible for water hardness (magnesium and calcium) are exchanged for sodium ions harbored by the ion exchange resins. The resulting product water exhibits a hardness of 0-60 mg/L and is essentially categorized as soft water.

    Figure 6 Ion exchange water softener.

    Back to the guide ⇪

    Do You manufacture Two-bed Ion Exchange Water Vessels?

    Yes, NEWater is practically an all-inclusive manufacturer of ion exchange water treatment equipment. Our two-bed deionizer systems typically comprise twin pressure vessels whereby one vessel harbors anion exchange resins and the other cation exchange resins. These systems are primarily used to eradicate both anionic and cationic pollutants.

    Two-bed deionizers operate by first removing the cationic impurities once the feed water is pumped through the cation exchange resin. The positive particles are efficiently substituted by hydrogen ions before the cationized water is passed through the anion exchange resins. The negatively charged contaminants are then swapped for hydroxyl (OH-) consequently generating demineralized water.

    Back to the guide ⇪

    How do Mixed-bed Ion Exchange Systems Work?

    Typically, mixed-bed ion exchangers constitute a singular tank fitted with blended cation and anion exchange resins. The exchange resins are characteristically miniature resin beads often measuring 0.010 mm or less. The feed water is disseminated evenly across the mixed-bed ion exchange resins to facilitate efficient demineralization.

    Consequently, the anion and cation IX resins comprising hydrogen (H+) and hydroxyl (OH-) ions attract the charged ions from the feed water and instantaneously replace them. The presence of both positively and negatively charged ions in the resins facilitates optimum deionization. The effectiveness of mixed-bed deionizers means they are more suited to polishing water from two-bed deionizers.

    Is It Advisable to Drink Deionized Water?

    Technically, deionized water is purified water devoid of minerals (demineralized water). It is consumable since it has no instantaneous health threats but most health experts are opposed to drinking deionized water. On the contrary, it is purposefully generated for use in industrial, pharmaceutical, and laboratory applications.

    The consumption of deionized water is only advisable if it is initially remineralized. Its consumption is also harbored by its arguably unpleasant taste, which is a consequence of mineral deficiency.

    Are There Deionized Water Tanks for Groundwater Treatment?

    The concentration of groundwater is often reminiscent of the nearby soil configuration. The minerals and other pollutants present in adjacent soils are reflected in the extracted well water. Therefore, the applications of untreated groundwater are limited unless a well water treatment system is deployed.

    NEWater’s well water deionization machines eradicate the hardness ions, iron, salt ions, and other mineral contaminants found in groundwater. They guarantee up to 99.9% efficiency scores and their operational costs are pretty inexpensive.

    Back to the guide ⇪

    What is Regeneration in Deionized Water Tanks?

    Deionized water tank regeneration entails the dislodging of accumulated ionic impurities from the ion exchange resins and the subsequent redistribution of resin beads. This allows the ion exchange resins to uphold their optimum productivity rate and mitigates deterioration in product water quality.

    The regeneration process occurs in varying stages as we briefly expound underneath. First, backwash rinsing is deployed to wash off the build-up of suspended solids. Subsequently, a regeneration solution (caustic or acidic) is pumped into the Ion exchange column. In mixed-bed deionizers, the cation and anion IX resins are first alienated. Customarily, this is done at lower flow rates to permit optimum contact.

    The next step involves displacing the regeneration solution. This is attained by slowly rinsing the regenerator off using dilution water. Finally, the final rinse is initiated. This involves flushing water through the ion exchange resins at a normal flow rate until the desired water quality is exhibited.

    Back to the guide ⇪

    How Should Deionized Water Be Stored?

    Deionized water is a form of purified water and since it is generated in a reversible process, it can lose its qualities. Technically, demineralized water has a shelf life hence the need to store it properly. Exposure to CO2 prompts the formation of carbonic acid which harbors bicarbonate and hydronium ions.

    Storage of low volumes of deionized water is mainly done using chemically inert glass vessels. For larger volumes, HDPE vessels are preferred as the perfect storage containers. This is because they are non-corrosive, can sustain low temperatures, and minimize light exposure.

    Back to the guide ⇪

    What is the Resistivity of Water Generated by Deionized Water Tanks?

    Water purity is primarily measured by grading its electrical conductivity or resistivity. Resistivity is particularly a measure of the water’s resistance to electricity and is chiefly calibrated as ohms (Ω).

    Essentially, highly purified water has a high resistivity while low purity water has a low resistivity but higher conductivity. High-purity water at 25°C has a resistivity of 18.18 Mohm•cm.

    Back to the guide ⇪

    Which Polishing Processes are Used in Deionized Water Tanks?

    The production of ultrapure water necessitates the incorporation of a complimentary water treatment process. There are varying water treatment technologies viable for use as post-treatment processes for deionized water systems.

    The polishing process is deployed in deionized water machines to eradicate impurities that survive the deionization process. Remineralization is for instance utilized to restore essential minerals back to the water especially if it is intended for human consumption. Ultraviolet sterilization is additionally employed to disinfect the resulting water while electrodeionization might be used to lower PH concentrations.
