PURPOSE:To process a large amt. of water at a high flow rate under low pressure loss by forming a tower packed with ion exchange fiber to satisfy a specified relation of the tower length to the diameter. CONSTITUTION:A tower 3 packed with ion exchange fiber 4 satisfies the relation of 0.04<=L/D<=6, wherein D is diameter 9 and L is length 10 of the packed tower 3. Also, D and L satisfy 5<=D<=50cm and 2<=L<=70cm. Further, the packing density of the ion exchange fiber 4 is 0.10-0.30g/cm<3>, and length of the ion exchange fiber 4 is 0.2-2.5mm. The ion exchange fiber 4 has a composite structure of ion exchange polymer (e.g. polystyrene) and reinforcing polymer (e.g. polyethylene). The ion exchange fiber 4 is a mixture floor consisting of strong acid cation exchange fiber and strong base anion exchange fiber. |
