What is clean water? People use electrodialysis, ion exchange, reverse osmosis, distillation and other processing methods to remove heavy metals, microorganisms, organic matter, and radioactive substances in water. However, drinking such water for a long time is not conducive to health.
What is direct drinking water? Refers to water that meets the requirements of raw materials, through sterilization and sterilization methods, does not change the natural physical and chemical characteristics of water, drinking water. The stepper boilers and instant water boilers on the market are producing fresh boiled water with its energy-saving, safe, pure and healthy function of live water.
What is healthy water? Professor Li Fuxing, director of the IDM Institute of Biology in Beijing, proposed that only the water that satisfies the following seven criteria can be regarded as an ideal "healthy water": 1. It does not contain any substance that is toxic or harmful to the human body and has an odor. 2. The hardness of water is between 30-200 (calculated as calcium carbonate). 3. The human body needs moderate mineral content. 4, PH value is weakly alkaline 7-8. 5, dissolved oxygen in water is not less than 7 ml per liter and moderate carbon dioxide. 6. The half width of the water molecule group is less than 100 Hz. 7. The nutritional and physiological functions of water media (solubility, penetration, diffusion, metabolism, emulsification, detergency, etc.) must be strong.
Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
