4. Resin filter element of water purifier the biggest feature of resin filter element is to soften hard water by ion exchange and remove calcium and magnesium ions. Therefore, the resin filter element is mostly used in water softeners.
5. 한외여과막정수기의 (UF)
The ultrafiltration membrane filter element is aimed at: bacteria in water and colloids, rust, suspended solids, sediment and macromolecular organic matter with much larger volume than bacteria can be intercepted by ultrafiltration membrane. It is generally used in the third stage of water purifier. The filtering accuracy is up to 0.01 μ m.
6. 역삼투막정수기의 (RO)
Because the pore diameter of the reverse osmosis membrane (RO) filter element is very small, only clean water molecules can pass through, and other bacteria, viruses and heavy metal ions will be intercepted by it, with a filtration accuracy of 0.0001 μ m.
물론 RO 멤브레인의 수명을 연장하기 위해 여과 등의 전처리PP면활성탄을 수행합니다. RO 멤브레인은 일반적으로 네 번째 수준에서 사용됩니다.
