| description | PURPOSE:To enhance softening treatment capacity, by blowing air in a resin sedimentation bed formed by removing a supernatant liquid from the lower part of a column to uniformly stir said resin bed. CONSTITUTION:The softening treatment of water is performed by passing raw water through an Na-type strong acidic cation exchange resin from the upper part thereof. After the resin is regenerated by backwashing water, the resin is allowed to sediment and water is drawn out up to the upper part of the sedimented resin bed and the resin is regenerated by brine. Before and after this regeneration, air is blown in the resin sedimentation bed to uniformly stir said resin bed. By this method, the softening treatment capacity of water can be enhanced. |
