With nearly 20 full-scale facilities in operation or construction and a proven track record of success
in pilot studies on a wide variety of surface waters, the MIEX® process has earned its place in the
toolbox for disinfection byproduct (DBP) precursor reduction. One of the difficulties in implementing the process on a
larger scale was the inability to dispose of the concentrated brine solution from the regeneration
process. With the development of the bicarbonate regeneration system, the brine disposal issue will
not be as significant and will potentially lead to implementation of these facilities on a wider-scale
with higher system capacities. While the process is not inexpensive to operate, the estimated O&M
cost is similar or less than other DBP precursor removal technologies. Also, based on the particular
application, the amount of greenhouse gasses emitted to the atmosphere from the process can be
significantly lower than its peer technologies. This may lead to greater use of the technology as
more utilities become more environmentally aware and begin to look for ways to reduce their
carbon footprint. Includes 7 references, table, figures.
