Recent market studies, summaries of which are found on the
Internet, indicate that ceramic membranes are expected to show a global sales compound
annual growth rate (CAGR) in the range of 10 to 12% over the next five years
(2015 to 2020) (from the high $3 billion to the low $5 billion).
This sales CAGR is higher than for other ceramic
categories. For example, market studies indicate
the advanced/engineering ceramic category will have a CAGR in the 5 to 5.5% range
for the same period. And, the ceramic coatings
category is likely to be in the 7 to 8% CAGR growth range.
Ceramic membranes apparently are beginning to be used more
frequently in water and other liquid filtration applications, replacing the use
of polymer materials as filters. An estimate
found on the Internet suggests that ceramic membranes are now used in 35 to 40%
of such filtrations.
Ceramic membranes are more resistant to harsh environments, have
less maintenance costs, more mechanical strength, and longer operating life
than polymeric materials. But, they do
cost more initially.
