How to change the filter element of a water heater in a kindergarten school? Nowadays, most kindergartens have installed water heaters for kindergarten schools. For the sake of children's health, the filter element of the water heater for kindergarten schools needs to be replaced regularly. However, many kindergartens do not know how often to replace the filter element. So, how to replace the filter element of the water heater for kindergarten schools?

The fully enclosed pipeline design is adopted, with full rounded corners, hygiene, and safety. The standard for kindergarten and school water heaters is two types of filtration: three-stage filtration and five-stage filtration. The three-stage filtration is composed of melt blown PP filter element, compressed activated carbon filter element, and particulate carbon filter element. The fifth level is based on the third level, with the addition of RO membrane and post carbon. PP cotton is used to block large particles such as rust, mud, and insect eggs in water; The usual replacement time is 3-6 months; Compressed activated carbon is made by mixing granular activated carbon powder materials with inorganic liquid binders, pouring them into a special mold, using a high-pressure compression machine to form, and drying them after leaving the mold. The compressed activated carbon filter (CTO) in the water dispenser of kindergarten and school can deeply adsorb impurities, odors, and residual chlorine in the water, and filter out small impurities. In the pure water machine, it is used for the third stage and also plays a role in liking RO membranes. The service life is the same as usual, which is 3-6 months. Particle carbon is commonly made from coconut shells, fruit shells, and coal as materials, and is refined through special processes to form a website optimization company. Its surface is black amorphous particles with pore structure and excellent adsorption function, which is applied in the purification of gases and liquids. The granular activated carbon filter (UDF) integrates adsorption, filtration interception, and catalytic action, and can effectively remove pesticides, pesticide residues, organic solvents, and other chemical pollution caused by industry. It can also effectively remove organic matter, residual chlorine, and other radioactive substances from water, and achieve results in decolorization and deodorization. The usual usage period is 3-6 months. RO membrane, also known as reverse osmosis membrane, has a pore size of 0.0001 micrometers, which removes more than 99% of impurities in water except for water molecules. The effluent is pure water, used for the treatment of highly polluted water and high hardness water. The usual replacement time is 6-12 months. Although the water dispenser in kindergarten schools can conveniently provide healthy water for children, it is also necessary to carefully and regularly change the filter element during use to avoid secondary water pollution. This is the true meaning of allowing children to drink healthy water.
