Answer: Harmless to human body. Here’s why.
Resin is one of the commonly used materials for water purifier filter elements. The resin filter element mainly removes calcium and magnesium ions from hard water to soften the water. The resin filter element is filled with millions of fine porous resin balls made of insoluble exchange material.
Resin filter element: Resin is a porous, insoluble exchange material. The resin filter element in the water softener is filled with millions of tiny resin balls (beads), all of which contain many negative charge exchange sites that absorb positive ions.
When the resin is in its nascent state, these charge exchange sites are occupied by positively charged sodium ions. As the calcium and magnesium pass through the resin tank, they come into contact with the resin beads and displace the sodium ions from their exchange positions.
The resin preferentially binds strongly charged cations, with calcium and magnesium ions having stronger charges than sodium ions. The replaced sodium cation then flows down through the resin "bed" and out of the water softener, which delivers "soft" water.
Finally, all resin exchange sites are occupied by calcium and magnesium and can no longer proceed It works. It is commonly used as a water softener filter element. After filtering, it can pass through the resin regeneration agent (soft water salt). The most commonly used ones are time regeneration and flow regeneration. The most advanced one in the world is the German Enmet NS series water softener, which uses time/ Flow dual-program control technology effectively reduces water consumption and resin regeneration agent consumption, and is environmentally friendly and energy-saving.
Extended information:
The water purifier filter element generally contains KDF and activated carbon. It is to clean the polluted water to the state required for production and life, that is, to remove solid particles in the water, kill bacteria, and filter out harmful chemical components.
In order to ensure that the water purifier product meets the needs of customers, the installer should ensure that the inlet water quality, inlet water pressure, inlet water flow rate, water temperature, etc. of the water purifier meet the requirements in the product performance parameter table.
If the incoming water quality is not municipal tap water, you need to add a pre-filtration device in front of the water purifier. If the inlet water pressure is too high (more than 3 kg), you need to install a pressure reducing valve in front of the water purifier. If the water purifier is small (less than 1 kg), a booster pump needs to be installed in front of the water purifier.
When the water purifier needs to be installed in front of a heating device such as a water boiler, the installation of the water purifier should be ensured. The position is lower than the water boiler to prevent the steam in the water boiler from entering the water purifier and damaging the filter element of the water purifier.
All pipes, joints, faucets and other water-related accessories on the water purifier should comply with the requirements. National health standards.
Do not install it outdoors to prevent the ultrafiltration element from freezing.
Do not tighten the threaded joints with excessive force during installation. Prevent joint threads from slipping
