technical field

With the improvement of people's living standards, people pay more and more attention to food hygiene and safety issues. In recent years, many food hygiene accidents broke out, which has aroused widespread concern in the society. In many food safety accidents, the existence of "microorganisms" plays an important role. Therefore, how to effectively and efficiently sterilize bacteria has become an urgent problem to be solved in the field of society and scientific research.

Acid oxidation potential water (also known as strong acid water, acidification potential water, strong acid electrolysis water, acid oxidation potential water, functional water, etc.) is a kind of water with high oxidation reduction potential (ORP), low pH, and low concentration of available chlorine. This kind of water has strong oxidation ability and rapid killing of microorganisms.

Weakly acidic oxidation potential water, referred to as SAEW, is obtained by electrolysis of dilute sodium chloride or dilute hydrochloric acid solution. It is widely used because of its safe and convenient production method, low residue and no side effects.

In the traditional production equipment of acidic oxidation potential water, the electrolytic cells used are mainly diaphragm electrolytic cells. Diaphragm electrolyzer uses ion exchange membrane to divide the space inside the electrolyzer into two halves, and the positive and negative electrodes are placed in the separated electrolyzer. During operation, the electrolyte is injected into the electrolytic cell, and the electrolyte is electrochemically reacted by the current of the positive and negative electrodes, and the acid oxidation potential water is generated on the positive electrode side, and the alkaline reduction potential water is generated on the negative electrode side.

Although the diaphragm type electrolyzer can produce acidic oxidation potential water, the alkaline reduction potential water produced by the negative electrode has no bactericidal ability and is generally discarded, resulting in a loss of 50% of the utilization rate of tap water; and the chlorine-containing gas generated during the electrolysis process is extremely easy to Diffusion is not only difficult to be reused, but also pollutes the environment.

However, the concentration of available chlorine in the weakly acidic oxidation potential water obtained by it is low, and it is easily affected by some impurities during use, which leads to the rapid attenuation of available chlorine and affects the bactericidal effect.
