➣What are Deionization Exchange Tanks?
Deionization exchange tanks are components deployed in service deionization units to specifically eliminate objectionable ionic pollutants from raw water. They are dependent on synthetic resins, which harbor non-objectionable cations and anions. These resins facilitate the ion exchange process by swapping the harmful ionic constituents with hydrogen(H+) and hydroxyl ion (OH-).
The primary deployment of DI exchange tanks is in conjunction with reverse osmosis systems. However, they are applicable in some water treatment applications as solo systems i.e. water softening. NEWater’s DI exchange tanks are respectively endowed with distinct exchange capacities to accommodate the varying requirements of unique customers.
➣What is Deionized Water?
Deionized water is essentially purified water devoid of dissolved ion constituents and minerals. Deionization water is generated by a process referred to as ion exchange that substitutes the undesired ion elements with less-objectionable ions. Characteristically, deionized water lacks a chemical configuration hence it is mainly used in industrial processes.
Often, it is referred to as water blank because it mimics the chemical composition of the element it is added to. The absence of charged contaminants which account for a substantial amount of dissolved inorganics makes deionized water safe to use in pharmaceutical manufacturing.
➣How do Deionization Exchange Tanks Work?
The production of demineralized water using deionized water tanks is essentially a simple and economical filtration process. Primarily, the process is founded on ion exchange meaning that undesirable ions are exchanged for desirable ions. Essentially, the ion exchange resins are either held in separate pressure vessels (Dual-bed DI) or integrated into one vessel (mixed-bed DI).
Where the cation and anion exchange resins are alienated in different tanks, the feed water is first passed through the cation IX resin. The positively charged ionic elements are swapped by the hydrogen(H+) ions harbored by the cation IX resins before being driven into the anion vessel. Here, the water free of cationic constituents is evenly distributed in the anionic exchange resin consequently provoking the exchange of negatively charged impurities for hydroxyl (OH-) ions.
In integrated DI exchange tanks (mixed-bed DI), a rigorous mixture of cation and anion IX resins facilitates optimum substitution of objectionable cationic and anionic impurities for H+ and OH- respectively. Ultimately, a stream of high-purity water (deionized water) is collected and ready for instantaneous use since the deionization process is literally reversible.
➣What are the Pros of DI Exchange Tanks?

For your purchase to be successful, the underlying rewards have to exceed the investment and operational costs.
Luckily, NEWater’s DI exchange tanks guarantee swift returns due to their inexpensive purchasing and operational charges. Primarily, the purchasing price is reminiscent of the system’s specifications (e.g. size, design, exchange capacity, etc.).
The operational cost on the other hand seeks to encompass a myriad of production expenses such as installation, maintenance, and labor. Customarily, the generation of one gallon of deionized water costs 30-50 cents and the cost is relatively lessened when a reverse osmosis system is integrated (approximately 1-3 cents).
➣What are Deionization Exchange Tanks Made of?
Typically, DI exchange tanks are made of stainless steel often coated with rubber and in some instances fiberglass. Inside the DI exchange tanks lie ion exchange resins, which are primarily cationic, anionic, or a blend of both.
The IX resins are characteristically a hydrocarbon network made of organic polymers which consequently hold the cation and anion, functional groups. The IX resin bed is customarily made of perforated microbeads (with a radius of 0.25-1.25 mm). Quite often, gel resin beads are deployed owing to their sufficient capacities and chemical efficiency.
➣How do I Determine the Best Deionization Exchange Tank for My Application?
When planning to purchase deionization exchange equipment, there are varying factors you need to ponder. The process is particularly toughened by the variety of DI exchange systems offered by manufacturers.

- The number of gallons needed in a day.
➣What Grade of Water is Produced by Deionization Exchange Tanks?
Customarily, deionized water systems produce high-purity water devoid of nearly all ionic constituents. Deionized water is commonly classified as type II water, which is a common ingredient for most manufacturing processes. Additional water treatment processes help improve the deionized water quality by eradicating other pollutants.
The quality of the demineralized water generated is measured using electrical conductivity parameters. A reverse osmosis/deionization system characteristically generated ultra-pure water (type I) with a conductivity of 0.055 µS/cm.
➣How Do You Measure the Quality of Deionized Water?
Numerous parameters can be employed to establish the quality of water produced by a water treatment system. A simple and frequently utilized parameter is a measure of the water’s electrical conductivity. Ideally, dissolved inorganic constituents are electrically charged meaning higher conductivity is a show of highly contaminated water.
High-purity water on the other hand exhibit lower conductivity and higher resistivity (18.2 mΩ/cm) to electricity. This is explained by the low concentration of charged pollutants in the water. Other perimeters deployed to measure water quality include:
●TDS, BOD and TOC.
●Turbidity and dissolved oxygen.
➣How do RO/DI Water Treatment Units Work?
Reverse osmosis DI systems are essentially hybrid units comprising a reverse osmosis unit and an ion exchange system. The combination is utilized to remedy the limitations of the respective RO and deionization technologies. Ideally, the reverse osmosis unit effectively eradicates the dissolved organics which are relatively hard to eliminate using deionization exchange tanks.
On the other hand, the deionization exchange system eradicates virtually all ionic impurities resulting in the production of ultra-pure water. RO/DI units are prevalently employed in industrial wastewater treatment systems, pharmaceuticals, and laboratories. In addition, the utilization of a reverse osmosis unit prior to a DI exchanger shrinks the production cost.
➣What are the Different Types of Ion Exchange Resins?
Ordinarily, there are two primary ion exchange resins deployed in DI exchange tanks. Their differences are chiefly compounded by their different functional groups. This provides distinct industries with specialized solutions for their exclusive needs. Beneath are the primary types of IX resins utilized in water demineralization applications.
Cation exchange resins.
Cation exchange resins are technically positively charged resins comprising hydrogen ions (H+). They are further divided into strong acid cation resins and weak acid cations. SAC resins are dominantly used especially in water softening systems. They are also efficient in eradicating barium and radium but they are prone to fouling by manganese and iron. Weak acid cation resins are primarily deployed to eliminate alkalinity. They are highly tolerant to oxidation and hence are more durable.
Anion exchange resins.
Anion exchange resins are characteristically negatively charged and are chiefly categorized as either strong base anion or weak base anion resins. The SBA resins are more suited for TOC elimination, demineralization, and desilication. WBA resins ordinarily eradicate negatively charged ions from strong acids. However, they are often employed in tandem with strong base anion resins.
➣Do You Manufacture Laboratory DI Exchange Tanks?
Water is an essential commodity in laboratory applications given it is a universal solvent. However, the optimum operation of laboratories requires high-purity water or water that adopts the chemistry of the added solution. Therein, deionized water systems for laboratories are mandated by laboratories.
NEWater manufactures specialized lab water systems utilizing one or several water treatment technologies and is capable of producing high-grade purified water. Our engineers innovatively and uniquely design first-rate lab water treatment systems for hospital, academic and industrial laboratories.
➣What is the Difference Between Dual-Bed and Mixed-Bed Ion Exchangers?
Dual-bed ion exchangers are characterized by twin DI exchange tanks each harboring a different ion exchange resin. The cation exchange resin is housed in a distinct exchange tank while the anion exchange resin is found in a separate exchange tank.
On the flip side, mixed-bed ion exchangers are characterized by a single DI exchange tank housing a blended mixture of cation and anion exchange resins. Moreover, they are principally utilized as post-treatment procedures for dual-bed deionizers.
➣When is Regeneration Necessitated in Deionization Exchange Tanks?
Regeneration is a restoration process used to revitalize exhausted ion exchange resins. The frequency of regeneration in deionization exchange tanks is dependent on the quality of feed water and frequency of use.
Presently, reverse flow and co-flow regeneration are the primary regeneration technologies employed in DI exchange tanks. In the co-flow process, both the regeneration and the treatment solution trickle from the top of the column to the bottom. The reverse flow process on the other hand involves the regenerate flowing in a contradictory course of the service flow.
➣Do You Manufacture Portable Deionization Exchange Tanks?
The mobility of deionization exchange tanks especially for decentralized applications is a top priority. NEWater offers an extensive range of portable water filtration systems including compact and easy-to-install DI exchange tanks.

Nonetheless, we have commonly demanded standard sizes (0.5-45 ft3) readily available. These size variations take care of the deionized water quantity demands of both small-scale and enormous industries.
➣How Much Deionized Water Can DI Exchange Tanks Generate in a Day?
The exchange capacity of ion exchange systems literally determines the quantity of demineralized water produced in a minute, hour, or day. DI exchange tanks are commonly utilized in industries hence they characteristically have high exchange capacities.
Standard DI exchange tanks, for instance, are available with exchange capacities ranging from 40k to 800k Grains. Their flow rate ranges from 1 to 190 GPM which is considered adequate for lesser industries as well as large-scale operations.
➣Which Additional Water Treatment Technologies can be Used with DI Exchange Tanks?
The ion exchange process just like other treatment processes is incapable of eradicating all waterborne impurities on its own. As such complementary technologies are often exploited to target and eradicate or lessen the concentration of contaminants immune to the ion exchange process.
The incorporation of supplementary processes is primarily in the pretreatment or post-treatment phases. Pretreatment is mainly undertaken to mitigate the premature damage of the IX resins and it involves technologies such as carbon sand filters, reverse osmosis, multi-media filtration, and UF filtration.
Post-treatment or polishing is required where there is a need for ultra-pure water. Varying processes are viable for deionized water polishing but the technology is primarily determined by the imminent use. Applicable technologies include UV sterilization, electrodeionization, and mixed bed deionization for two-bed deionizers.
➣Which Contaminants do Deionization Exchange Tanks Remove?
By and large, DI exchange tanks remove charged organic and inorganic constituents harbored in raw water. The elimination of these impurities is selectively done. The cationic IX resin targets the positive constituents while the anion IX resin targets the negative constituents.
The employment of reverse osmosis facilitates the removal of non-charged organics such as bacteria. The cationic impurities eliminated include Magnesium (Mg2+), Calcium (Ca2+), Iron (Fe2+) Potassium (K+), and Sodium (Na+). The anionic pollutants eradicated include Nitrate (NO3-), Chloride (Cl-), Carbonate (CO3-), and Bicarbonate (HCO3-).
➣Do You Have In-House DI Exchange Tanks?
Yes. Ion exchange is a commonly utilized technology with its primary application in homes being water softening. The majority of water sources supplying utility and drinking water to households have significant concentrations of calcium, iron, and magnesium which are synonymous with water hardness.
Di exchange tanks, especially cationic exchangers are deployed as water softener systems. They provide softened water (0-60mg/l) which makes soaps more effective and averts the accumulation of scales on pipes and electrical appliances like kettles.
➣Do You Manufacture Industrial and Commercial DI Exchange Tanks?
NEWater is essentially a comprehensive manufacturer of DI exchange tanks and other water treatment systems. Our multi-national clientele transcends commercial and industrial users hence we provide specialized industrial and commercial DI exchange tanks.
Typically, our commercial and industrial deionization exchange tanks are highly effective with their primary difference being the exchange capacity. The manufacturing processes and components utilized are certified to ensure the system complies with the respective quality standards.
➣Does Electrodeionization Produce Deionized Water?
Electrodeionization is a contemporary water treatment technology driven by DC power, IX membranes, and resins to demineralize raw water. It simply substitutes the objectionable ionic constituents with desirable ions ultimately producing high-grade deionized water compared to ordinary ion exchange processes.
It is perceived as a worthy replacement for mixed-bed deionizers thanks to its impeccable deionization rate and efficiency. Furthermore, it is a chemical-free process with no volatile waste product hence it is environmentally friendly.
➣What are the Shortcomings of Deionization Exchange Tanks?
Deionization water systems are revered for their proficiencies in producing deionized water. However, their application in water treatment is limited in several ways. Typical DI exchange tanks only eradicate charged constituents leaving behind undesirable dissolved organics like viruses, bacteria, and pathogens.
In addition, the deionized water they generate is not recommended for human consumption due to the absence of fundamental minerals. Consequently, the ion exchange filters become overwhelmed thereby necessitating regeneration which results in the emission of concentrated waste.
➣How are Deionization Exchange Tanks Used in Seawater Desalination?
The deployment of deionization exchange tanks in seawater desalination is chiefly purposed to eradicate boron. However, the utilization of ion exchange resins in seawater filtration results in the removal of dissolved inorganics such as nitrate, calcium, sodium, and chloride.
For effective desalination, reverse osmosis deionization systems are employed. The reverse osmosis process shrinks the TDS levels to approximately 1000ppm or less from 35,000ppm or more. RO/DI water systems provide purified water with conductivity as low as 0.055 µS/cm.
