5. Micron filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um,
6. UF system-- Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane.
7.UV sterilizer-In the UV disinfection process, water is purified as it runs through a stainless steel chamber that contains a special UV- producing lamp.
