ABSTRACT:
A method is described that relates to reducing amounts of regenerant waste or increasing the concentration of regenerant waste from ion exchange processes. A method is described that may allow a batch ion exchange process to compete on these factors with continuous or simulated continuous ion exchange processes, and/or to improve the efficiency in operation continuous or simulated continuous ion exchange processes. A specific application addressed is the treatment of water in the Coal Bed Methane Process.
