Laboratory DI Water System  from NEWater

A laboratory deionization system is one that produces water of extremely high purity, meaning that the conductive media in the water are almost completely removed, while the non-dissociated gases, colloids, and organic matter (including bacteria) are also removed to a very low level.

NEWater uses a combination of advanced reverse osmosis technology and ion exchange technology, and the water quality can be as high as 18.2 megohms, which meets the requirements of ultra-pure water quality required by laboratories. We use a microcomputer single-board machine program control, water quality detection automatic display, so as to obtain high-quality output water, its water resistivity can generally reach 18MΩ/cm.

NEWater laboratory deionized water system ensures high module pressure resistance and no water leakage. Since the concentrated water is filled with patented resin, which reduces the membrane resistance, the system does not require concentrated water circulation and salt injection in the freshwater chamber filled with layered resin, which is more conducive to the removal of weak electrolytes. Our system is simple, simple piping, only the inlet pipe, product pipe, and concentrated water pipe are needed, no circulation pump and salt injection system, no PLC program controller is needed, system construction cost and maintenance cost is low.

The Ultimate FAQ Guide for Laboratory DI Water Systems.

In laboratory settings, high-grade potable water is highly coveted due to its role as a universal solvent. Water characteristically has a chemical composition, which could potentially alter the composition of lab solutions and results. To avert this, raw water is often preconditioned using laboratory water treatment systems such as deionized water systems. Beneath, we are going to evaluate laboratory DI water systems and the quality of water they supply to laboratories.

➣What is a Laboratory DI Water System?

A laboratory deionized (DI) water system is a set of interconnected water treatment equipment used to generate deionized water for laboratory applications. The deionized water systems for laboratories simply rely on the ion-exchange process to eradicate nearly all of the ionized impurities present in the raw water.

Typically, laboratory DI water systems provide laboratory deionized water, which is characteristically Type II water. With resistivity of 1-15MΩ·cm, the deionized water is essentially purified water that can be deployed in a series of laboratory applications such as diluting concentrated solutions and as a cleaning agent.

➣What are the Primary Uses of Laboratory DI Water Systems?

The deployment of DI water systems for lab is chiefly aimed at generating an acceptable grade of purified water suitable for laboratory applications. The system gets rid of ionic impurities, consequently producing a grade of water with no chemical identity and therefore cannot alter the chemistry of lab solutions and results.

Additionally, laboratory water purification systems help laboratories adhere to industry standards by supplying a grade of purified water that is in line with the prevailing regulations. They simply facilitate the smooth running of laboratories by reliably providing the most coveted laboratory ingredient.

➣How do Lab DI Water Systems Operate?

Technically, laboratory DI water systems are highly specialized ion exchange systems that eliminate ionized pollutants from water in a reversible ion exchange process. The deionization process carried out by laboratory deionized water system is enforced by synthetic exchange resins made up of cation and anion exchange resins.

The cation and anion exchange resins are often separately housed in distinct columns or uniformly mixed in a single resin bed. Once the raw water is passed through the exchange resin beds, the cationic and anionic minerals are effectively substituted for hydrogen (H+) and hydroxyl (OH-) ions respectively.

The continued deionization of raw water often results in the building up of objectionable particles on the exchange resins. As such, a regeneration process to revitalize the exhausted resins is enforced using backwashing and the injection of acidic or base reagents appropriately.

➣Do You Provide Distinct Types of Laboratory DI Water Systems?

Water deionizer systems are generally available in distinct categories characterized by varying specifications and working principles. To be precise, NEWater manufactures three types of laboratory DI water systems.

Laboratory mixed-bed DI water systems.

The mixed-bed DI water system is characterized by an integrated cation and anion exchange resin bed.  This integration augments the deionization rate often resulting in a higher grade of deionized water. They are additionally viable post-teatment systems for two-bed di water systems.

Laboratory dual-bed DI water systems.

The dual-bed DI water system has the anion exchange resin and the cation exchange resin accommodated in separate yet adjacent DI columns. The quality of demineralized water generated is not as high as that generated by the other systems but they are unmatched in their cost-efficiency.

Laboratory EDI water systems.

The electrodeionization system generates high purity water characterized by a resistivity of 18.2MΩ·cm. The process is electrically powered and is dependent on IX resins and membranes.

➣What is Laboratory Deionized Water?

Laboratory deionized water is essentially Type II purified water bereft of virtually all ionized minerals. This grade of purified water typically has a high resistivity to electricity given that virtually all the ionized constituents have been stripped off. To be precise, the resistivity of laboratory-type II water is ordinarily 1-15MΩ·cm.

Further subjecting the water to a post-treatment phase using electrodeionization equipment or mixed-bed deionizers purifies the water further. This water is perfect for media production, general chemical and sample dilution owing to its non-existent mineral composition.

➣What Quality of Water do Laboratory Deionized Water System Generate?

Ordinarily, laboratory deionized water systems produce deionized/demineralized water. The quality of the deionized water generated may differ depending on a number of factors such as the feed water quality and the type of lab DI equipment used.

The deionized water quality is measured by examining its electrical conductivity or resistivity. Typically, the water has a resistivity of 1-15MΩ·cm hence it is categorized as Type II DI water. Nonetheless, ultrapure water can be generated using hybrid laboratory DI systems such as EDI water systems (with a resistivity of 18.2MW/cm).

➣What Types of Resins Are Used in Lab DI Water Systems?

Deionized water exchange tanks primarily utilize two types of ion exchange resins, the anion exchange resin, and the cation exchange resin.

Cation exchange resins.

These are characteristically positively charged resins filled with hydrogen (H+) ions. They particularly eliminate the positively charged elements such as Magnesium (Mg2+) and Sodium (Na+) by substituting them for H+ ions. They are further divided into:

• Strong acid cation resins.
• Weak acid cation resins.

Anion exchange resins.

The anion exchange resins are particularly negatively charged resins characteristically made of hydroxyl (OH-) ions. They replace the anionic (negatively charged) impurities with OH- thereby producing deionized water. They are further categorized as:

• Strong base anion resins.
• Weak base anion resins.

Back to the guide ⇪

➣How Do You Regenerate Exhausted Laboratory DI Resins?

The incessant use of a laboratory DI water system results in the exhaustion of the deionization resin. This is brought about by the excessive accumulation of elements on the resin’s surface. A coping mechanism enforced to restore the optimal abilities of the exchange resin is called regeneration.

The regeneration process is technically commenced by backwashing the resin. Water is pumped through the resin bed from the bottom and as it flows upwards, the accumulated elements are dislodged and captured by the water. Subsequently, a specified solution (acidic or base) is injected into the resin bed to restore the original electrical charge of the resin.

A slow rinse step is then enforced prompting the regenerant to evenly settle on the resin bed. Finally, raw water is pumped through the resin bed during the fast rinse process to make certain the projected water quality is attained.
