Pure water production line disinfection

Here we would like to share the pure water production line disinfection

 1. Disinfection of production water In the international arena, the commonly used method in the field of drinking water disinfection is disinfection of chlorine dioxide disinfectant. Because chlorine dioxide disinfectant has the advantages of safety, high efficiency, broad spectrum and fast action, no tertiary substances (teratogenic, carcinogenic, mutagenic) and no stimulation to the human body during the time period, it is listed by the World Health Organization as A1 grade safety and high-efficiency disinfectant, and can remove odor and colored iron and manganese ions in water to improve water quality. It can be directly added to water body sterilization with 0.5-1.0mg/L chlorine dioxide.

2. The control of microbial contamination of filling equipment, pipeline system, water treatment system equipment, disinfection and filling equipment, pipeline system and water treatment system equipment is mainly practical chemical disinfectant, reservoir, stainless steel pipeline, water treatment equipment (including ultrafiltration system), batching tank, pipeline disinfection concentration of 50mg / L, can be sterilized by scrubbing, spraying, soaking cycle, etc., rinse with pure water or sterile water after five minutes. Disinfect once a week. In order to reduce the oxidation of the membrane system, care should be taken to avoid equipment containing membrane systems. 

3, PE buckets, barrels for disinfection and recycling of barrel lids, as well as the purchase of barrel lids and caps, the sanitary condition is poor, and the cleaning and disinfection of empty barrels is thorough, which is directly related to the quality of the products. It is the focus of quality control of drinking water production products. (1), the dynamic cycle disinfection and recovery of PE barrels washed with alkaline washing water and then 50-80mg / L chlorine dioxide disinfectant through the automatic washing machine high-pressure spray disinfection, disinfection time is 10 - 15 seconds. After disinfection, it is not necessary to rinse with pure water. After slightly controlling the disinfectant in the dry bucket, it can be filled. A very small amount of chlorine dioxide in water can be used as a preservative to extend the shelf life of pure water. The disinfectant can be recycled, and every 20 hours, it is necessary to add 20% of the original disinfectant amount - 30% as a consumption supplement. The disinfectant is formulated into a 2000 mg/L concentrate and continuously added. The disinfectant is prepared daily. The heavily polluted recycling drums and bottles need to be immersed in 50mg/L chlorine dioxide disinfectant for 5-10 minutes, and then dynamically disinfected by the above method.

Note: In order to reduce the chlorine dioxide overflow during the washing process, it is best to close the bottle washer in the small room and install a small exhaust fan on the top of the small room to exhaust the outside. (2) Static immersion disinfection If there is no dynamic disinfection equipment. After washing the barrel, it can be immersed in 50~60mg/L chlorine dioxide disinfectant for 5~10 minutes, and the disinfectant in the dry barrel can be filled.

Disinfection of the lid and cap: soak for 5 to 10 minutes with 50-80mg/L chlorine dioxide disinfectant.

 4, production environment disinfection production environment disinfection mainly includes production of air disinfection, wall, ground and equipment surface disinfection. There is mold in the air in the filling workshop, which is the main way to contaminate pure water mold. The workshop uses two methods for disinfection. One is to spray chlorine dioxide into 100 mg/L disinfectant solution, and continue to maintain the disinfection time after spraying for 10-20 minutes. Second, the chlorine dioxide is formulated into 3000 mg/L disinfectant for fumigation (200g). Applicable to 4000 m3 space), close the doors and windows, air supply equipment and UV lamp when fumigation. Such as fumigation can enhance indoor air circulation, the effect is better. Disinfect once a day before production. 5, the operator's hands, clothing disinfection during the production process

The operator's clothing has the presence of mold and should be treated with disinfection. Wash your hands carefully with hand sanitizer twice, then wash your hands in 80-100mg/L chlorine dioxide disinfectant for 1 minute, then dry naturally after washing. After washing the overalls, soak them in 50mg/L chlorine dioxide disinfectant for 5 minutes, dry or dry.
