UF water purification technology is also known as ultrafiltration. This technology uses low-pressure membranes to retain only useful ions, minerals, and mineral salts and remove large-sized harmful particles from the water source.
- The filtration process takes place at normal temperature and low pressure, so it consumes less power, saving maximum costs. At the same time, this technology does not waste water as wasteful as RO, so it also contributes to water saving and environmental protection.
UF water purification technology is also known as ultrafiltration.
Weakness:
- Residue, moss and bacteria will be trapped at the bottom of the filter cup, therefore, after a period of use, there will be deposits causing blockage of the filter, affecting water quality.
