KENT's patented Mineral RO TM Technology retains essential natural minerals in purified water using the TDS Controller, thereby providing 100% safe and tasty drinking water. The double purification of RO + UV / UF removes even dissolved impurities such as chemicals, bacteria, viruses and salts, making water 100% pure. In conventional RO TM Technology, only 20% of water is recovered as purified water and about 80% is rejected. KENT's Save Water Technology employs a computer-controlled process that recovers more than 50% water as purified water. The rejected water is stored in a separate tank that can be utilised for mopping and washing, resulting in less water wastage.
