Abstract
PURPOSE: To obtain treated water of high purity by passing respective regenerating agents through a double-layer cation tower and a double-layer anion tower after finishing passage of raw water from the lower part of each tower as rising streams while fluidizing the resin layers and expanding them in a predetermined range to simplify the regenerating process as well as to reduce the amt. of the agents used.
CONSTITUTION: Acid regenerating agent 14 is diluted with desalted water 15 and let to flow in double-layer cation tower 4 after finishing passage of raw water 1 from the lower part of tower 4 through equal distributor 16 as rising streams. At this time, SC (strongly acidic cation exchange resin) layer 3 and WC (weakly acidic cation exchange resin) layer 2 are fluidized and expanded by 20W120% with the streams, and waste liquor after regeneration is discharged through collector 17. On the other hand, desalted water 15 alone is supplied to tower 4 to regenerate layers 3,2. In double-layer anion tower 12, the resin layers are regenerated with alkali regenerating agent 18 in the same way as that in tower 4. As a result, layers 2,3, WA layer 10 and SA layer 11 are regenerated almost separately, and the original double layers are formed in the towers again.
