Water Deionizer Work Flow

How Does a Water Deionizer Work?

The deionization process, also called the de-mineralizing process, is the process of removing any potential mineral salt ions through ion exchange. This process uses anion and cation exchange resins to replace various anions and cations in the water. It is a fast and reversible process. Water deionizers are highly efficient, can remove unwanted impurities to obtain decontaminated water, and support automatic regeneration.

According to different water quality and usage requirements, the outlet water resistivity can be controlled between 1~18M Therefore, deionized water purification system is widely used in the chemical industry, electroplating ultrapure water, boiler feed water, and pharmaceutical ultrapure water production.

How to Regenerate a Deionized Water System?

In the process of water production through ion exchange, the ion exchange resin will automatically adsorb calcium, magnesium ions, and other hardness impurities in the raw water, with the use of a period of time will gradually reach saturation, replaced by anions and cations in the water and failure, must be regenerated by the system in order to continue to prepare high-quality pure water.

NEWater deionization systems can automatically regenerate the anion and cation beds of the system. The brine will flow through the resin at a slower rate to replace the impurity ions attached to the resin, thus realizing the continuous operation of the system and stabilizing the production of water.

2.Deionized Water Systems

Do I Need a Deionized Water System?

If you require higher quality water for domestic drinking, car cleaning, laboratories or industrial facilities, then we recommend a deionization system. It reduces the hardness of your feed water, consistently producing better-tasting deionized water. Deionized water can be used as drinking soft water and can also be used for car cleaning. It will not produce spots and water stains, and avoid scaling on the surfaces of household appliances and industrial equipment.

Many companies rely on water from deionized water systems to manufacture their products. Some of them are:

Pharmaceutical companies, cosmetics companies, electronics manufacturing companies, food processing companies, agricultural companies, military, mining companies, power and energy companies, oil refining companies and disaster relief companies.

Is There a Difference Between a Deionized Water System and Reserve Osmosis?

Yes, there is.

The most significant contrast between the two is that reverse osmosis utilizes a semipermeable film to channel water. In contrast, deionization utilizes exchange resins to replace minerals and foreign substances with hydrogen and hydroxyl particles.

Reverse osmosis removes protozoa, viruses and bacteria from water, while deionization acts as a purifier and water softener, removing only unwanted ions from the water.

Deionization is a water treatment measure that deals with mineral salt foreign substances, while reverse osmosis utilizes pressure to turn around the water stream.

What Is the Difference Between Deionized Water and Distilled Water?

Though both of them apply the same process of removing ionic impurities, they are not the same.

Both are types of pure water, but they are produced in different ways. The distillation cycle can consume the most time, particularly when a lot of water should be bubbled, cooled, and collected.

  • Deionization can be performed somewhat rapidly – mainly if a mixed bed resin is utilized, so the water is just necessities to pass one time.
  • Deionization gets rid of ions present in the water, whereas distillation removes impurities from water.
  • Distilled water is used in all laboratory applications because it is pure whereas, deionized water is used vastly since it is easier and cheap to make.

Which are the Methods of Water Deionization Applied?

At NEWater, we use the following methods to deionize water:

The two-bed deionizer

It involves two vessels – one containing a cation-exchange pitch in the hydrogen (H+) structure and the other containing an anion sap in the hydroxyl (OH-) structure. Water travels through the cation portion, after which all of the cations is exchanged for hydrogen particles.

Mixed bed deionization.

The cation-exchange and anion-trade gums are actually mixed and contained in a singular squeezing factor vessel. The cautious mix of cation-exchangers and anion-exchangers in a lone area makes a mixed-bed deionizer similar to a long series of two-bed plants. Accordingly, the water quality from a mixed-bed deionizer is extensively higher than that made by a two-bed plant.

Electro-deionization System.

It kills particles from liquid streams, customarily identified with invert assimilation (RO) and other filtration devices. Our extraordinary deionization modules constantly produce ultrapure water up to 18.2MW/cm. EDI may be run industriously or irregularly. It eliminates particles from fluid streams, ordinarily.

4.Methods of Water Deionization Applied

What Is the Cost of a Deionized Water System?

The type of deionized water system and how it is customized greatly affects the cost of the system. The cost depends on customer-driven factors such as the brand of the system, size, type of quality, quality of membranes used, water quality requirements, and the design of the customized system.

Back to the guide ⇪

Can Deionized Water Systems Remove All Impurities from Water?

No. Although it removes minerals and salt extremely, deionization does not remove dissolved organic chemicals, viruses, bacteria, and particulates.

Due to that reason, deionization systems are configured typically with carbon filtration, ultraviolet (UV) purification, and reverse osmosis (RO) to remove these additional contaminants.

Back to the guide ⇪

Which Piping Systems are Suitable for Deionized Water Systems?

Generally, plastics are used mainly because of their relative cost and resistance to corrosion. Of course, there are other options that we use:

  • Chlorinated polyvinyl chloride_ does not show any wearing signs or corrosion while conveying any type of water.
  • Polyvinyl chloride_ which is cost-effective.
  • Polypropylene _ offers installation methods that promote ultra-pure applications.
  • Polyvinylidene fluoride _ contains additives to ensure non-leaching properties.

Back to the guide ⇪

Do Deionized Water Systems Cause Corrosion of Pipes?

Yes, it does.

The piping system breaks down when used in high-purity water systems. Deionized water can be destructive to carbon steel because of its low hardness content. Deionized water systems are usually dealt with and put away using austenitic tempered steels, as the carbon will taint the generally pure water.

6.Piping System

Another reason for corrosion might be High oxygen levels due to internal oxidation.

What Are the Risks Associated with Deionized Water Systems?

As much as deionized water systems have benefits, especially in industries, it is advisable to avoid consuming deionized water because deionized water is inadequate in particles, it can retain the particles in your body after drinking it. Since magnesium and calcium are both simple for deionized water to ingest, it can likewise take these issues.

Numerous individuals believe that deionized water doesn’t taste so fantastic. This is because it is free from particles and minerals. In contrast to different sorts of water, deionized water isn’t the best kind of water to take.

Back to the guide ⇪

What is the Required Temperature for Deionized Water Systems to Work?

A high temperature is the best for deionization to take place.

A low temperature or freezing temperature will cause the tank or distribution tool to crack, allowing the resin to escape from the deionizer. It is therefore advisable to drain the water from the deionize.

Back to the guide ⇪

How Does Soft Water Extend the Life of a Deionized Water System?

Soft water is ideally the best water for any appliance to last since it contains no minerals such as iron and magnesium that reduce the lifespan of the deionized water system. There is no mineral buildup on the insides, hence increasing its longevity. There are also no stains on the appliances.

Does a Water Deionization System Remove or Reduce Dissolved Oxygen in the Water it Processes?

No, it doesn’t.

Oxygen O2 is not an ionic molecule, so it is unaffected by deionization. However, the level of dissolved oxygen will change due to all the pressure changes while the water is pumped through the deionization system. The system you use should reduce the dissolved oxygen.

Can One Use a Pressure Washer with a Deionized Water System?

Absolutely yes. As a matter of fact, it is the easiest way to cut resins.

The essential supporter of resin utilization is the measure of water you course through the framework in a given measure of time. The spout we supply with the framework utilizes around 2 GPM of water with a standard private water pressing factor, and presently there are numerous electric pressure washers that alone utilize 1.2 GPM. We like mixed drink napkin math, so how about we call that a Deionized Water Systems?

The subsequent request impact of a pressing factor washer is that it is effectively twice as viable as a spray nozzle: a pressure washer blasts pollutants away while a nozzle sprays them off. So rather than spraying the nozzle four or multiple times, across the hood, simply blast it twice. This is much easier.

What are the Factors that Might Decrease the Lifespan of a Deionized Water System?

Our deionized water system should last for a great deal of time. Some of the factors that might contribute to the decreased lifespan of a deionization water system are the quality of local water, frequency of use, and subsequent maintenance.

Those factors should constantly be monitored to ensure the optimum operation of the deionization water system and to guarantee its lifespan. However, that should not worry you since our deionization water systems are made of industry-standard components as required by international CE and ISO bodies of quality guarantee.

Back to the guide ⇪

How Do You Maintain a Deionized Water System for  Home?

Due to its numerous benefits, it is advisable to know how to maintain the system as well.

Some of the tips we advocate for include:

Being the best water to use for cleaning cars, use it in a bucket, not a pipe. The more water you use, the shorter the lifespan of the system. It has been also advised that one should use the deionized water filter along with the pressure washer.

Avoid using the deionized water system along with the domestic water softening system. It is also advisable to connect the deionized water filter, in the same way, to pass in the same direction from the resin every time.

When you are done with the rinsing, disconnect the deionized water filter and let the water drain out of it. If you let the water remain in the filter, it will impact its longevity. Many resins get affected by solar radiation, so never commit the mistake of leaving your ultra-pure deionized water system under direct sunlight.
