Things you didn’t know about electrolytic water deodorization

Slightly acidic electrolytic hypochlorite water deodorization technique A method of electrolyzing salt water to produce hypochlorite water with deodorization effect. This technique has been widely used in several fields, and its deodorization effect has been supported by several studies.

Hypochlorous acid water can effectively remove a variety of volatile odor substances, such as hydrogen sulfide, ammonia and so on. These gases are converted into non-volatile ions or compounds through an electrolysis process, thus achieving deodorization effects. In addition, electrolytic water is also used in air purification systems to filter and deodorize inhaled air through filters and ultraviolet lamps.

Specifically, electrolyzed water has a significant removal effect on different types of odor components. For example, Japan’s Morinaga Dairy Co., LTD., research shows that electrolytic water can effectively remove dimethyl disulfide, ammonia, butanol, propionic acid and other odor components. In addition, acidic electrolytic water has the highest deodorization rate for TMA (trimethylamine), reaching 99%. This shows that the anode electrolyte is particularly good at dealing with nitrogen based odor components.

In addition to the above advantages, hypochlorite water also has the characteristics of environmental protection and energy saving. Compared with traditional chemical treatment methods, electrolytic power supply is more environmentally friendly and energy-saving in water treatment. It can not only improve water quality, but also reduce the use of chemicals, thus reducing environmental pollution.

It is worth noting that hypochlorite water also has some limitations in practical applications. For example, in some cases, electrolytic water may not be able to completely remove all types of odor components. For example, the removal effect of ethyl acetate is not ideal. Therefore, when choosing electrolytic water as a means of deodorization, it is necessary to determine the best solution according to the specific odor composition.

In short, electrolytic water deodorization technology has been widely used in many fields because of its high efficiency, environmental protection and energy saving characteristics. Despite some limitations, its excellent performance in removing a variety of volatile odor substances makes it a deodorant method worth promoting. It can also remove odors from the water and purify the air by generating hypochlorite ions. These hypochlorite ions can neutralize organic matter and odor molecules in the water, thus achieving the effect of deodorization. Electrolytic water is also used for cleaning and disinfection, which can effectively remove the smell of vegetable corruption, toilet odor, livestock and poultry breeding odor.

In terms of specific applications, electrolytic water deodorization technology is widely used in the purification of toilet air, through the decomposition and removal of smelly bacteria sources generated in the toilet, as well as the suppression of the generation of toilet odor. For example, TOTO smart toilet uses electrolytic water sterilization technology, by spraying electrolytic water hypochlorite sterilization water to eliminate odors and bacteria growth.

What specific types of odor components is electrolyzed water most effective at removing?

Electrolytic water (especially slightly acidic electrolytic water or hypochlorous acid water) can effectively remove the following odor components:

Vegetable spoilage odor: including methyl mercaptan, dimethylsulfuric acid and dimethyl disulfide.

Toilet odor: mainly ammonia gas.

Livestock breeding odors: These odors are usually caused by a variety of volatile organic compounds.

Pungent sour taste: such as propionic acid.

Rotten egg odor: hydrogen sulfide.

Smelly fish smell: trimethylamine.

Sweat odor: n-butyric acid.

Footwear odor: n-valeric acid and isovaleric acid.

In addition, electrolytic water has also been shown to be able to convert harmful gases such as formaldehyde and ammonia into harmless gases, and due to the simultaneous production of hypochlorous acid, sodium hypochlorite, hypochlorous acid ions and hydroxyl radicals and other substances, thus maximizing deodorization efficiency. The electrolytic water sterilization and deodorization system in the smart toilet also shows a high removal rate of odor concentrations such as ammonia nitrogen and hydrogen sulfide, which can reach more than 90%.

What are the specific environmental and energy saving advantages of hypochlorite water deodorization technology compared with traditional chemical treatment methods?

• No chemicals: electrolytic water deodorization technology does not require any oxidant or reducing agent to be added during the treatment process, so it has a minimal impact on the environment and is known as an environmentally friendly water treatment technology.
• No secondary pollution: electrolytic water deodorization technology will not produce harmful substances, avoiding the traditional chemical treatment method may cause secondary pollution problems.
• High efficiency and energy saving: electrolytic water deodorization technology can effectively improve the overall efficiency of the system, saving energy consumption 5 ~ 15%. In addition, the low voltage water electrolysis ozone generator has a high energy utilization efficiency and reduces energy consumption.
• Less sludge: The amount of sludge produced by the electrochemical process is 40% less than that of the traditional dosing treatment process, which greatly reduces the disposal cost of the sludge.
• Low operating cost: Although the investment of electrochemical treatment process is comparable to that of traditional dosing treatment process, its operating cost is only 1/5 ~ 1/10 of that of traditional dosing treatment process.
• Safe and harmless: electrolytic water formed by electrolytic water deodorization technology will automatically return to ordinary domestic water after use, which is harmless to human body.

Sum up

In summary, for different types of odor components, the choice of electrolytic water deodorization program should be based on the following principles:

Hydrogen sulfide (H2S) : The preferred method of using water washing combined with electrolytic water to produce ozone.

Ammonia (NH3) : The preferred method of using water washing combined with electrolytic water to produce ozone.

Amines: The method of using activated carbon adsorption combined with electrolytic water to produce ozone is preferred.

Mercaptan: The preferred method of using water washing combined with electrolytic water to produce ozone.

After collecting the odor in a sample bag, the researchers added tap water or slightly acidic electrolytic water into it, and then vigorously shook it for 30 times, and conducted odor analysis with the FF-2020 gas recognition device. The test results are as follows:

According to the above results, it can be seen that electrolytic water has excellent removal effect on dimethyldisulfide, ammonia, butanol and propionic acid, and has good removal effect on hydrogen sulfide, trimethylamine, ethanol, n-butyric acid, n-valeric acid and isovaleric acid, but has no effect on ethyl acetate. That is to say, slightly acidic electrolytic water can well remove the smell of vegetable corruption, toilet odor/livestock odor, pungent sour taste, etc., the removal of rotten egg odor, smelly fish odor, sweat odor, shoes and socks odor can also reach about 40%, if the use of electrolytic water is properly increased, its removal effect will be improved to a certain extent.
