| titleOfInvention | Purified water manufacturing method and purified water manufacturing apparatus |
| abstract | A purified water production method capable of sufficiently removing organic matter from water to be treated while preventing a decrease in the pH of purified water, shortening the recovery time of chloride ion concentration, providing purified water at a low cost, and suitable for space saving. and provision of water purification equipment. A method for producing purified water, comprising the following steps (1), (2), (3) and (4) below. Step (1): A step of dividing the water to be treated W1 containing at least bicarbonate ions and organic matter into water to be treated W1A and water to be treated W1B. Step (2): A step of flocculating the water to be treated W1A with a flocculant to obtain treated water W2A. Step (3): A step of subjecting the water to be treated W1B to ion exchange treatment in an ion exchange tower 42 filled with an anion exchanger 41 having chloride ions to obtain treated water W2B. Step (4): A step of mixing treated water W2A and treated water W2B to obtain mixed treated water W2. [Selection drawing] Fig. 1 |
