METHOD FOR COUNTERCURRENT REGENERATION OF AN ION EXCHANGE RESIN BED |
摘要 |
An improved method for regenerating ion exchange resin in a treatment tank having a flow direction, which includes the steps of providing a supply of regenerant under pressure into the tank, and introducing the regenerant into the tank in an opposite flow direction to the treatment flow direction. In the preferred embodiment, the regenerant is a combination of CO2 which is mixed with water to form carbonic acid and citric acid. This mixture is then introduced into the treatment tank without storage. <IMAGE> |
