The Application of Chlorine Dioxide in Water Treatment in the Food Industry Author: Shandong Weifang Haijie Environmental Protection Equipment Co., Ltd. The H-series pure chlorine dioxide generators are divided into two types: those equipped with flow meters and those equipped with metering pumps. It mainly consists of the reactor main unit, pressure water flow meter, inlet metering pump (or flow meter), and material tank. Among them, the metering pump-type generator is capable of producing chlorine dioxide disinfectants of various concentrations with high precision, making it most suitable for use in food processing enterprises. Its working principle is that sodium chlorite and hydrochloric acid are precisely delivered by metering pumps into the reaction tower within the reactor (for example, 200 grams), and the flow rate of the pressurized water is adjusted using a pressure water flow meter (for example, 1000 liters per hour). At this point, a chlorine dioxide disinfectant with an accurate concentration is produced at the outlet (for example, under these conditions the concentration of the disinfectant is 200 mg/l = 200 ppm). This device has the following advantages when used in food processing plants: 1. By connecting it to a pressure water source and a metering pump, it can produce chlorine dioxide disinfectant at the desired concentration, allowing for immediate use and convenience. 2. Precise concentration: Since both the pressurized water and the reaction materials are measured with precision, the concentration of the product is accurate. 3. Low cost: The cost of producing 1 ton of disinfectant with the same concentration as that of 2% chlorine dioxide stabilized solution using this equipment is 700 yuan, whereas the cost of purchasing 1 ton of 2% chlorine dioxide stabilized solution is 4000–6000 yuan. The cost saved by an ordinary food processing plant in 3 months is enough to purchase a generator. 4. It eliminates the risks associated with storage and the troubles of frequent transportation. 5. Ready for use immediately, with good safety features, and it reduces corrosion of surrounding equipment and items. 6. It prevents damage to the human body caused by the chlorine dioxide steady-state solution during the activation process. 7. Chlorine dioxide not only has disinfecting properties and a secondary sterilizing effect, but it also serves to preserve the quality of fruits, vegetables, aquatic products, meat products, etc., as well as to degrade pesticide residues. The production water, pipelines, containers, vessels, and workbenches in food factories (including fish processing plants, vegetable processing plants, fruit processing plants, meat product processing plants, pure water plants, etc.) must be regularly disinfected. Buying 1 H-series pure chlorine dioxide generator developed and produced by our company specifically for this industry will meet all the production needs of the enterprise.
