    The Ultimate FAQ Guide for Deionized Water System for Laboratory.

    Laboratories necessitate varying grades of high-quality product water to operate smoothly. The quality of product water needed for certain laboratory applications cannot be met by the ordinary tap water supply line. Only specialized laboratory water purification systems can provide the desired water quality and help laboratories adhere to industry regulations. As a seasoned manufacturer and supplier of laboratory water treatment equipment, we attempt to answer your burning questions on deionized water systems for laboratories.

    Figure 1 Deionized water system for laboratory.

    What is a Deionized Water System?

    A deionized water system is a water treatment system that utilizes the reversible ion exchange process to eradicate ionized pollutants from water. Deionized water systems for laboratories are personalized systems devised to reliably provide laboratory-grade water. They essentially generate Type II deionized water, which is chiefly used as a cleaning agent or for general applications.

    Customarily, laboratory water deionizer systems are deployed jointly with reverse osmosis systems. This makes the deionization process cost-effective and elevates the deionized water quality. Electrodeionization water systems can also be employed in place of traditional water deionizer systems to supply laboratory Type II DI water.

    What are The Primary Uses of Deionized Water Systems for Laboratories Used?

    Deionized water systems for laboratories are essentially exploited to generate laboratory-grade water for general lab usage. Conventional laboratory water deionizer systems provide distinct laboratories with type II di water while electrodeionization water systems can provide high purity water. The deionized water they provide is ideal for use as a cleaning agent given it leaves no spots on the apparatus.

    They are also used to generate purified water, which is primarily used as a dilution solvent. The deionized water is essentially devoid of impurities and does not threaten to alter any lab processes or test results. Additionally, laboratory water deionizers are manufactured with great precision to ensure they conform to laboratory standards. This helps laboratory operators adhere to the prevailing regulations.

    How do Deionized Water Systems for Laboratories Work?

    Essentially, water deionizer systems employ the process of ion exchange to generate laboratory-grade di water. The process removes virtually all dissolved ions from raw water by replacing them with desirable ions consequently producing deionized or demineralized water.

    The feed water, which can be well water or tap water is driven into the di exchange tanks where the di exchange resins reside. In two-bed deionizers, the water is initially injected into the cation exchange tank, where all positively charged ions are pulled towards the anionic functional groups. The cation resin beads, which are characteristically charged with hydrogen (H+) or sodium (Na+) in the case of water softeners, release these non-pollutant ions.

    The hydrogen ions replace the displaced cationic pollutants and the water that exits the cation exchange tank is practically free of cationic impurities. Subsequently, this water is driven into the anion exchange tank where the anion exchange resin resides. The cationic active sites in the resin bed attract the anionic impurities while the anionic resin beads release the hydroxyl ions to replace the displaced impurity ions.

    In mixed-bed deionizers, the water is pumped into a single tank where both the anion and cation exchange resins reside. The anionic and cationic impurities are simultaneously exchanged for hydroxyl (OH-) and (H+) ions respectively. Electrical balance in the water is maintained by replacing monovalent ions with one non-pollutant ion and divalent ions with dual non-pollutant ions.

    What Grade of Water is Produced by Deionized Water Systems for Laboratories?

    Conventional two-bed and mixed-bed deionizers for laboratories generate Type II deionized water. This is characteristically purified water lacking virtually all ionic pollutants. Type II laboratory-grade water has a relatively high resistivity to electricity owing to the low ionized constituents content. The average resistivity of type II deionized water is ≥1 MΩ-cm at 25°C while its Total Organic Carbon (TOC) averages <50 ppb.

    This grade of laboratory deionized water is commonly used for general practices, electrochemistry, and general spectrophotometry among other applications. Laboratory water electrodeionization systems often produce high purity water or Type I water. The purity levels are quite high averaging a resistivity of >18 MΩ-cm and a TOC level of <10 ppb. Type I water is primarily used in analytical laboratories in applications like gas chromatography, cell culture, and molecular biology.

    Which Deionized Water Systems Are Used In Laboratory Water Purification?

    Water deionization equipment commonly used in laboratories can be categorized as either two-bed deionizers, mixed-bed deionizers, or electrodeionization equipment.

    ● Two-bed deionizers.

    Two-bed deionizers are distinguished by their twin di exchange tanks. One tank accommodates the cation exchange resin while the other one holds the anion exchange resin. The cationic impurities and anionic impurities are eliminated in distinct exchange vessels. The deionized water produced is high-quality but does not equal the purity levels of the deionized water produced by mixed-bed or electrodeionization water systems.

    Figure 3 Two-bed deionizer system.

    ● Mixed-bed deionizers.

    Mixed-bed deionizers combine the anion exchange resins and the cation exchange resins in a single exchange tank. The entire ion exchange process is undertaken in a single vessel. This allows for the exchange of nearly all ionic pollutants resulting in deionized water with relatively higher quality. As such, mixed-bed deionizers are commonly employed to polish the deionized water from dual-bed deionizers.

    ● Electrodeionization water systems.

    As their name suggests, electrodeionization (EDI) water systems are electrically driven as opposed to chemical-driven two-bed and mixed-bed deionizers. They make use of both ion exchange membranes and resins to produce high purity water with an extremely high resistivity of >18 MΩ-cm. Their effectiveness is tremendously proliferating their prominence and they are steadily overshadowing mixed-bed deionizers as the ideal polisher for two-bed deionizers.

    What is the Cost of Deionized Water Systems for Laboratories?

    Laboratory water deionization plants bear distinct price tags, which essentially mirror the type, size, and primary features of the equipment. Manufacturers and suppliers are also likely to price their deionizers differently. Owing to the unpredictability of market conditions and the variation in equipment properties, NEWater prefers to provide accurate price quotations. Visit our website and simply send us a price inquiry.

    Having a rough understanding of the projected operating costs also helps prospective purchasers plan their budgets better. It is paramount that you factor in expenses such as installation, energy usage, labor, and maintenance. Again, these factors are quite unpredictable and they are likely to vary depending on the region and type of feed water utilized.

    Past and present experiences, however, show that the estimated cost of generating laboratory-grade deionized water ranges from $0.30 to $0.50 per gallon. Running a reverse osmosis system prior to the employment of a water deionizer system has proven to lower operational expenses. The cost of producing demineralized water using a reverse osmosis di water system ranges from $0.01 to $0.03 per gallon.

    Which Regeneration Process is Used in Deionized Water Systems for Laboratories?

    Regeneration is a vital process instigated at the end of an in-service cycle. Primarily, regeneration is designed to eliminate the trapped solids and ultimately recharge the deionization resins. Here is a breakdown of the process followed when regenerating deionized water systems for laboratories.

    Backwash. Suspended solids and other particles amassed during the in-service cycle are eliminated through backwashing. Water is injected in an opposing direction to the typical service flow thereby forcing the resin bed to suspend. The trapped particles also become suspended and are ferried away by the backwash water on its way out. You should consult your manufacturer to establish the ideal backwash rate. Customarily, the flow rate when backwashing cation resins should be approximately 6 GPM/ ft2 of surface area while the flow rate for anion resins should be roughly 3 GPM/ft2.

    Regenerate injection. An appropriate regeneration solution is then introduced into the deionization tanks to recharge the DI resins. Sulphuric acid and hydrochloric acid are mainly used to regenerate cation resins while sodium hydroxide (NaOH) or caustic soda are used to recharge the anion resins. Adequate contact time should be accorded to facilitate optimal regeneration.

    Slow rinse. This is also referred to as regenerant displacement. At a slow flow rate, dilution water is introduced into the exchange tanks to displace the excess regeneration solution. Typically, the dilution water is flushed at a flow rate similar to the flushing of the regeneration solution.

    Fast rinse. Water is passed through the resins at a higher flow rate to sufficiently rinse the resins. The fast rinse process is carried out until the emitted water attains a desirable quality.

    The regeneration process is well-illustrated in the following video. Caution when handling the regeneration chemicals and wastewater is paramount.

    Do You Provide Reverse Osmosis DI Water Systems for Laboratories?

    Coupling deionization water systems with reverse osmosis systems have proven to be quite rewarding. The operating costs are significantly lessened and the quality of deionized water produced is massively enhanced. NEWater manufactures first-rate reverse osmosis di water systems accommodative of laboratory applications among others.

    Essentially, the reverse osmosis system is used for primary treatment of the feed water removing pollutants such as bacteria, viruses, minerals, and dissolved salts. The reverse osmosis water is then introduced into the water deionizer system where all dissolved ions are effectively eradicated. Reverse osmosis EDI water systems are a much more effective alternative with the capability to deliver ultra-pure water.

    Figure 4 Laboratory RO/EDI water system.

    How Do You Troubleshoot a Deionized Water System for Laboratory?

    Experiencing problems with your deionized water system for the laboratory can be very frustrating. The hitches can be severe thereby necessitating professional aid or mild meaning you can resolve them by yourself. Underneath, we look at some tips you can employ to troubleshoot your laboratory water deionizer and get to the root cause of the hiccup you are experiencing.

    ● Checking the service flow rate.

    A drop in the service flow rate is an indication that your deionization resins are probably clogged. To resolve this hitch, you need to backwash the di exchange tank to dislodge the amassed suspended solids.

    ● Measuring the quality of deionized water produced.

    Constantly monitoring the quality of demineralized water generated helps you notice any depreciation in quality. The drop in quality could be caused by exhausted resin beads, which might permit pollutant ions into the filtered water.

    Can Electrodeionization Water Systems Be Used in Laboratory Water Purification?

    Electrodeionization (EDI) water systems are advanced water deionization systems driven by direct currents to eradicate ionized contaminants using ion exchange resins and membranes. Their application as laboratory water purification systems is in ascension courtesy of their resourcefulness and economic maintenance.

    Laboratory EDI water systems can produce high-purity water (Type I) with an optimum resistivity of >18 MΩ-cm and a TOC level of <10ppb. They hardly impact the taste or odor of the water given they do not utilize chemical regenerants. EDI systems can be used to refine deionized water from traditional ion exchange filters as well as membrane filters. They can also be employed as standalone plants to supply first-rate laboratory-grade deionized water.

    Back to the guide ⇪

    How Can You Polish the Water Generated by a Deionized Water System for Laboratory?

    Despite being incredibly effective in eliminating ionized pollutants from water, water deionizer systems are pretty poor in removing non-ionized constituents. They do generate purified water but the presence of non-ionic impurities can only be eliminated using post-treatment systems.

    ● Electrodeionization water systems.

    EDI water systems and mixed-bed deionizers are commonly used to refine the grade of deionized water derived from two-bed deionizers. However, EDI systems are more revered owing to their higher rejection rates, cost-efficiency, and dependability.

    ● UV water sterilizers.

    Deionized water is likely to harbor pathogens like bacteria and viruses, which can cause waterborne illnesses in humans.  To eradicate them, a UV water sterilizer using germicidal rays is needed. The UV water disinfectant destroys the DNA cells of microbes thereby curtailing their growth or reproduction. They remove up to 99.9% of disease-causing microorganisms found in water.

    Figure 5 UV water sterilizer.

    ● Reverse osmosis systems.

    Reverse osmosis systems can also be employed to polish the deionized water from water deionizers. They eliminate dissolved solids and a range of other unwanted impurities. The deployment of RO systems as secondary treatment systems to lab water deionizers guarantees the production of high purity water.
