The lack of feasible and cost effective disposal options for concentrate (brine) from
inland nanofiltration or reverse osmosis membrane (NF/RO) systems is a major challenge
to the continued growth of membrane technology for the treatment of drinking water both
nationally and in Colorado. A multi-party workgroup was formed to advise the Colorado
Government on developing an environmentally and economically effective concentrate
disposal policy to assure membrane treatment technologies remain a viable option in
Colorado. Over a one year period the workgroup studied this issue and developed a set
of consensus findings. In summary, the findings of this group were:
traditional disposal methods are of limited suitability for Colorado;
while expensive, membrane processes using zero liquid discharge (ZLD)
technologies can be cost competitive with alternative treatment trains, not using
membranes, when the need to treat multiple contaminants exists, and if the value
of recovered water is included in the estimate; and,
funding should be provided for demonstration pilot project of ZLD technology.
