1Equipment principle and composition：

AUK-CIO electrolytic salt method sodium hypochlorite generator is a type of electrolytic dilution method that uses non membrane electrolysisSodium chloride（A device for producing sodium hypochlorite solution from NaCl aqueous solution. The equipment consists of an electrolytic cell, an electrolytic power supply, a salt dissolution box, a dilute salt box, a storage box, a dosing device, and inlet and outlet pipelines.

The electrolytic power supply adopts a voltage not exceeding24V or 36V DC power supply. In an electrolytic cell with special electrode plates (titanium based coated rare metal oxides of ruthenium, rhodium, iridium, and platinum), dilute salt water with a predetermined concentration is electrolyzed to produce sodium hypochlorite solution. The disinfectant dosing system automatically adds the sodium hypochlorite solution generated by the equipment to the water to be disinfected for disinfection.

The total electrochemical reaction of the electrode is expressed as follows:

NaCl+H2O→NaClO+H2↑

Electrode reaction:

Anode:2Cl- -2e→Cl2

Cathode:2H++2e→H2

Solution reaction:2NaOH+Cl2→NaCl+NaClO+H2O

4、 Characteristics

The electrolytic salt method sodium hypochlorite generator of Shanghai Aoke Environmental Technology Co., Ltd. is a disinfection equipment with multiple unique patented technologies developed in the "948" introduction and promotion project of the Ministry of Water Resources, based on the reference of advanced foreign technology and combined with actual domestic usage conditions.

① Unique electrode descaling technology, no acid washing and maintenance required:

The electrode adopts a unique coating technology that can adapt to frequent reverse polarity for descaling. At the same time, the electrode works symmetrically in both forward and reverse directions, which solves the problem of efficiency decline or malfunction caused by continuous scaling during long-term use of the electrode. At the same time, it avoids the electrode acid washing system that is necessary for traditional equipment of this kind, so that the electrode does not require special maintenance during use.

② Adopting the latest structural design from abroad, with a compact size:

The electrode adopts a new type of rectangular structure with pure series connection, and a micro scale removal device is installed at the bottom of the electrolytic cell. This reduces the volume of the entire electrolytic cell to one-third of the traditional method. In addition, the acid washing device without the electrode is removed, making the main unit of the equipment very compact. The miniaturization of volume makes equipment very convenient for transportation, installation, maintenance, and other aspects, and the price has also significantly decreased compared to traditional methods.

③ Fully automatic precise dosing:

The control center PLC of the equipment comes with 4-20 mA and RS485 input modules, which can be directly connected to the output signals of the online residual chlorine monitoring instrument and flow meter (one or several) of the water plant. According to the changes in the residual chlorine value of the factory water and the actual water supply, the dosage of disinfectant can be adjusted in a timely manner to ensure that the residual chlorine value of the factory water is always stable within a reasonable range, thereby avoiding the odor or insufficient dosage of disinfectant caused by excessive dosage at the user end.

At the beginning of equipment operation, a disinfectant dosage is initially set based on the actual flow rate and water quality. Then, according to the measured residual chlorine value in the factory water, if it is too high (or too low), the disinfectant dosage is reduced (or increased), so that the residual chlorine value in the factory water gradually reaches the range required by the specifications.

④ Remote monitoring:

The device comes with a remote transmission module, which can achieve remote automatic monitoring of disinfection equipment as long as it is equipped with a regular mobile phone card. The administrator can also monitor the working status of the device at any time through their mobile phone.
