Application details of ultrafiltration filter element in the catering industry-【3M filter element】

The standard 10-inch ultrafiltration filter element is to protect the water health problems of the catering industry. An effective restaurant water purification solution is to adopt a water purification system with a tap water pipe directly connected to the ultrafiltration membrane module. The ultrafiltration filter element completely solves the food hygiene caused by water pollution. Security Question. The tap water is filtered through an ultrafiltration system to effectively remove residual chlorine, rust, colloids, bacteria, and reduce turbidity in the tap water, so that the produced water reaches the standard of direct drinking water. u003cbru003e　　 At present, 80% of the water used in catering shops is generally tap water, and the water consumption can generally be divided into the following conditions: u003cbru003e　　1. Washing vegetables: The basic operation of a restaurant is definitely based on the dishes. Whether the dishes are clean or not is directly related to the sanitation of the dishes. However, the tap water is polluted by the water source, and many sanitary indicators exceed the standard, especially the rust in the water. Where the water quality exceeds the standard, the more chlorine-containing bleaching powder is put into the water, the organic matter in the water combines with excess chlorine to form trihalomethane, which is a human carcinogen. Therefore, washing vegetables with tap water will not clean the vegetables, but will leave more Of harmful substances. u003cbru003e　　2. Cooking rice: Although cooking rice will boil water and mix it with rice, it dissolves harmful substances in tap water directly with rice. u003cbru003e　　3. Drinking water: Now basically every restaurant will provide or sell tea, that is, boil the tap water for direct drinking or make tea, and boil the 'problematic' tap water into 'boiling water' for drinking. The microorganisms in the water are killed, and the heavy metals, organic matter and other pollutants that originally came from the water remain in the water. u003cbru003e　　 Drinking water directly. This drinking method has been popular in developed countries in Europe and America for 20 years. It has become popular in some cities in my country in recent years. Ultrafiltration membrane filter elements are constructed in major cities in the Pearl River Delta to build a quality water supply network for the purpose of drinking tap water directly. High-end real estate in Beijing, Shanghai, Guangdong and other places have also played the 'water' brand one after another to show their brand's excellence. u003cbru003e　　 Ultrafiltration membrane filter element For the catering industry, the implementation of direct drinking water terminal supply is even more imperative. The catering department uses high-quality water to soak and wash the cooking food, which can better ensure the hygiene of the catering, thereby improving the taste of the catering, meeting the health requirements of customers, establishing a good reputation, and attracting more customers. u003cbru003e　　 Process flow: u003cbru003e　　1. Pipe laying: ensure that the raw water is tap water; u003cbru003e　　2. Ultrafiltration membrane module: The ultrafiltration membrane module is directly connected to the tap water pipe, which can effectively remove suspended solids such as sand and rust in the tap water, trap bacteria and viruses such as Escherichia coli, flagellates, and bacteriophages, remove chlorine, and produce water up to National drinking water standard. u003cbru003eThe advantages of 　　 ultrafiltration used in catering water purification: u003cbru003e　　1. Ultrafiltration can completely remove bacteria, viruses, etc. in the water body, and retain the trace elements needed by the human body; u003cbru003e　　2, ultrafiltration can completely remove algae; u003cbru003e　　3. Ultrafiltration can completely remove chlorine in tap water; u003cbru003e　　4. Ultrafiltration has a large amount of water, which can meet the water needs of restaurants of different sizes; u003cbru003e　　5. The ultrafiltration membrane module can be directly connected to the water pipe, which is simple to install, small in area, and low in use.
