1: Product purity is very high, almost no harmful by-products
Physical isolation side reactions: The sulfonic acid membrane has strong selective permeability. Which can accurately isolate the anode area and the cathode area to
prevent the chlorine gas generated by the anode and the sodium hydroxide (lye) generated by the cathode from mixing directly.
Performance indicators: Higher effective chlorine concentration: Membrane electrolysis allows for a more concentrated reaction. And the effective chlorine concentration produced is typically more than 10 times that of the diaphragmless method and more than 4 times that of the conventional diaphragm method.
Extremely low byproducts: Effectively inhibits the formation of chlorate and potentially carcinogenic trihalomethanes (THMs). This ensures that the produced hypochlorous acid fully meets stringent water quality standards for food and even pharmaceutical grades.
2：The electrolysis efficiency is greatly improved, and the energy consumption and salt consumption are lower
The sulfonic acid film has a very high ionic conductivity (mainly conducting H+ or Na+). Which can significantly reduce the internal resistance of the electrolyzer:
Voltage reduction and power saving: when using the perfluorinated sulfonic acid/carboxylic acid double layer composite membrane, the voltage of the electrolytic cell is lower. The data show that the operating power consumption can be reduce by about 23.5% compare with the single membrane.
Improved current efficiency: The current efficiency of the membrane method system is usually about 1.2 times that of the non-diaphragm or traditional forced circulation system. Under the premise of achieving the same available chlorine production. The electricity consumption can be reduced by about 17%. And the salt consumption (raw material consumption) can be reduced by about 16%.
3：The PH value is precisely controlled, and the hypochlorous acid is more stable
Precise adjustment of slightly acidic range: Hypochlorous acid (HClO) has the strongest bactericidal effect (up to 80 times that of sodium hypochlorite) in slightly acidic environment with $text{pH}$value of 5.0-6.5, and is the safest.
Avoid alkalization: The sulfonic acid membrane will isolate the alkaline substance (NaOH) in the cathode area and discharge. So that the anode area or mixing area can output pure, slightly acidic hypochlorous acid without free base very stably. This kind of pure secondary chemical property is more stable. Not easy to decompose, and prolongs the shelf life of the disinfectant.
4：Excellent corrosion resistance, longer equipment life
Resist strong oxidation environment: the electrolytic cell is extremely strong oxidation, strong acid or strong alkali environment, ordinary diaphragm is easy to aging, perforation or blockage.
Ultra long life: the main chain of the perfluorinated sulfonic acid film has a similar structure to Teflon (Teflon), with strong chemical stability and thermal stability. It can not only withstand the oxidation of high concentration of free chlorine. But also keep the tank voltage stable in long-term operation. Greatly reducing the maintenance frequency of the equipment and the cost of membrane replacement.
Comparison of comprehensive economic benefits
From the perspective of long-term operation. Although the initial equipment procurement cost of sulfonic acid membrane is slightly higher. It benefits from the reduction of energy consumption. Salt consumption and the extension of equipment life:
The integrated operating cost of the membrane electrolysis generator is about 46% lower than that of the separateless electrolysis method.
It is about 56% lower than the conventional diaphragm method.
This means that in food processing, animal husbandry, aquatic preservation, hospital disinfection and other scenarios requiring large amounts of water and high-quality hypochlorous acid. Therefore the generator using sulfonic acid membrane technology has unparalleled long-term economic and safety advantages.
FAQ
Is the hypochlorous acid produced by the sulfonic acid membrane electrolysis hypochlorous acid generator more pure?
Yes, under the same conditions, sulfonic acid membrane electrolysis (also known as membrane electrolysis) to produce hypochlorous acid purity is usually higher.
This is mainly due to its “isolated” design, which effectively reduces by-products and impurities
