Only half a month after disinfection of the drinking fountains, the bladder was contaminated with bacteria, and the passing rate of the total number of colonies dropped sharply from 100% to 40%. After one month, the passing rate of colony colonies was 0; the passing rate of mold and yeast was also reduced to 70% after one month, and after two months, all were unqualified; the situation of E. coli was relatively better. The qualification rate of 0-2 months in the bladder was 100%, but after 3 months, the qualification rate dropped to 80%. In the fourth and fifth months after disinfection, the passing rate of E. coli was reduced to 70%, and the heating temperature of the drinking fountain was only 90. About °C, less than kill all bacteria.
If there is no professional instrument in the center of the water dispenser, it is difficult to wash it thoroughly. The water dispenser divides the inner liner and the outer bladder. In the process of changing the water, the water dispenser liner will still contain nearly 1000 ml of water for more than 3 days. If not used, it will breed E. coli and other poisonous bacteria attached to the inner wall of the dispenser. Disabling drinking fountains for a period of time or under conditions of high temperature and high humidity results in greater secondary pollution.
How long has it been cleaned and how has it been cleaned? According to experts, in general, regular use of drinking fountains must be cleaned within two months, and it is best to ask a professional cleaning company or person to clean. "Like powerful liner descaling, high pressure circulating filtration, sealed ozone sterilization and high temperature steam sterilization and other necessary links, all require professional tools and methods." Industry sources said.
White vinegar cleaning water dispenser
The use of white vinegar to clean the water dispenser is both healthy and thorough. It must be noted here that according to the different water dispensers, the dosage of white vinegar is not the same, but one principle is to fill the heating tank and the standard is to use vinegar. After pouring it in, turn on the tap and let it go. See if you have vinegar, and you can see that you have enough vinegar. Thirty minutes after soaking, the faucet and the drain pipe at the same time are opened, and the descaling effect is achieved. Acetic acid in white vinegar can react with calcium carbonate and magnesium carbonate in the scale to generate carbon dioxide and water, thereby achieving the purpose of removing scale. In addition, white vinegar can also kill bacteria and other harmful substances deposited in drinking fountains.
The biggest feature of the temperature regulating valve is that it only needs an ordinary 220V power supply and uses the energy of the regulated medium to directly automatically regulate and control the temperature of steam, hot water, hot oil and gas. It can also be used to prevent overheating or heat exchange. The valve has the advantages of simple structure, convenient operation, wide temperature regulation range, fast response time and reliable sealing performance, It can be adjusted at will during operation, so it is widely used in hot water supply in chemical industry, petroleum, food, light textile, hotels and restaurants.
