What is a water purifier electrode plate? 3 notes about the electrode plate when choosing to buy an alkaline ionized water purifier

Alkaline ion water purifier is gradually becoming a familiar product for Vietnamese users. The electrode plate is a very important part of this machine but not everyone understands it well. Refer to the following article, to better understand the electrode plate of the water purifier, as well as understand 3 notes about the electrode plate when choosing to buy an alkaline ionized water purifier!

What is the electrode plate in the alkaline ionized water purifier?

The electrode plate is an important part, as precious as the heart of an alkaline ionized water purifier. It can be said that the electrolyte machine will be a normal water purifier if there is no electrode plate, because the machine is only capable of producing clean water, without the ability to create alkaline ionized water.

Structure

The electrode plate is made of titanium, with a platinum coating on the outside to speed up the electrolytic performance. Depending on the brand of the machine, the electrode plate will have different shapes, sizes, and convexities. In addition, the higher the number of electrolytic plates, the more hydrogen molecules are generated, which means that the generated water has a high oxygen resistance.

Working principle of electrode plate in alkaline ion water purifier

The electrolysis machine has two main parts: the internal filter and the electrolysis chamber.

The job of the internal filter is to perform the pre-filtration of the water. After the water source has been cleaned and qualified, then the water will enter the electrolysis chamber for the electrode plates to perform their role. At this time, the water molecules will be electrically separated into H+ and OH- ions.

The electrode plate starts to do its job, then in the electrolysis chamber, the following chemical reaction will occur:

• 2 H2O(l) → 2 H2(g) + O2(g)

Next, at the negative and positive terminals of the electrolysis chamber, the following chemical reaction will occur:

At the positive (+) terminal, the water will be separated according to the following equation:

• H2O → H+ + OH–
• 4OH– → 4OH+4e => 2H20+O2

At the other anode, there are more H+ ions than OH-, so the water is acidic (pH less than 7).

At the negative terminal (-), water will be separated according to the equation:

• H2O → H+ + OH–
• 2H+ 2e → H2

At the other negative electrode, OH- is more than H+ ions, so the water is alkaline (pH>7).

Through the water separation process, it shows that alkaline ionized water will come out at the cathode with OH- and molecular hydrogen (H2) groups, while acidic ionized water will come out at the anode with H+ and Oxygen ions. (O2).

Types of electrode plates available on the market

Currently, the electrode plate on the market is used differently depending on the purifier, but there are mainly three types: flat electrode plate, grooved electrode and mesh electrode.

For flat or grooved electrodes: These two types have the advantage of long life, easy cleaning after use. However, due to the use of titanium and platinum materials for production, the product cost is quite high, compared to other electrical panels.

For the mesh electrode plate: Contrary to the two plates mentioned above, this electrode has low cost, stronger electrolytic performance. However, it is more difficult to clean, because to clean it requires special cleaning technology specifically for it. Along with that, the product life is also lower than that of flat and grooved electrodes.

Function of electrode plate

The electrode plate is considered as the most important part of the electrolyte, accounting for more than 75% of the capacity to improve the electrolysis efficiency of alkaline ionized water. The quality and technology of the electrode plate will determine the width of the pH range and the concentration of dissolved hydrogen.

Why are so many electrode plates needed?

If the same technology and the same surface area can produce water with a wide pH range and high concentrations of dissolved hydrogen, as many electrode plates as possible should be used. Currently, the material to make the electrode plate is often very expensive, so the machine with many electrode plates, the price will be very high.

Three things to note about the electrode plate when choosing to buy an alkaline ionized water purifier

Electrode plate area

This is one of the criteria that users need to pay attention to when buying and using. According to experts, they encourage consumers to choose electrode plates with a large area, block shape will be better than electrode plates with a small area.

Because the working capacity of the electrode plate is large, it will be stronger and more durable. Not only that, the large area allows more contact with water, increasing the electrolytic efficiency, thereby increasing the Hydrogen content in the water.

Number of electrode plates

Choose an alkaline ionized water purifier with many Platinum-coated Titanium electrodes for the highest electrolytic performance, increasing the ability to handle complex water sources. In particular, in Vietnam, the water source has not been treated well, with a lot of lead and metals mixed in it, etc. The water usually doesn’t have calcium, the pH is quite low.

Therefore, the more number of electrode plates will help increase the width of the pH range, thereby ensuring the quality of the output water, providing the most accurate pH reading.

Material of electrode plate

According to a leading expert, it is advisable to choose an alkaline ionized water purifier with a platinum-coated electrode plate, because this is the only metal in the world that is completely non-toxic and affects human health.

Besides, in the electrolysis process, Platinum helps to improve performance, increases the Hydrogen content in alkaline ionized water, helping to improve the machine’s life.

What are the methods of cleaning the electrode plate?

Basic

Electrode plates that have been used for a long time should be cleaned according to the correct method. Currently, the most basic methods that are trusted by many users can be mentioned as follows:

Built-in automatic cleaning according to the function of the machine

With this cleaning method, the machine will automatically spray acid water to clean the electrode surface for about 10-15 seconds and discharge it from the drinking nozzle (water is used about 5-10 liters). This method is quite convenient because the user does not need to remember the exact time to clean the electrode plate, and there is no need to spend extra money to buy additional cleaning chemicals.

Active hygiene of the user

If your water purifier does not have automatic cleaning of the electrode plate, you can actively clean it by taking slightly acidic water after using it about 10 times. This will ensure the electrode plate is always clean, providing the best source of water to your family.

Depth

To clean the electrode plate in the best way, people often use an intensive cleaning service that combines physical and chemical to remove stains, for example, the Digi Clean electrode restoration service.

Digi Clean is the most complete electrode plate cleaning solution tested by the Pasteur Institute, it is powered by a combination of citric acid and the cyclonic pressure of water to help remove stubborn stains. In addition, it also helps to prolong the life and improve the performance of the machine.
