<p>PROBLEM TO BE SOLVED: To provide a water treatment method with an improved treatment speed per carrier. SOLUTION: Raw water is circulated between a tank A in which a carrier is charged and a tank B in which no carrier is charged and the circulation number of times [=(total vol. of tanks A, B÷inflow amt. of raw water per unit time)÷(vol. of tank A÷circulation amt. of water per unit time between tanks A, B)] given by dividing the value, which is obtained by dividing the total vol. of the tanks A, B by the inflow amt. of raw water per a unit time, by the value which is obtained by dividing the vol. of the tank A by the circulation amt. of water per a unit time between the tanks A, B is set to 10 times or more.</p> |
