Federal research laboratories use the ultrapure water produced by hyperfiltration technologies to develop advanced microelectronics like this
thin-film solar cell.rounds of chemistry and adjust-
ments of controls to fully automate
the system and ensure reliable
operation. Users must evaluate
the benefits and drawbacks of
different chemistries to make an
informed decision about which
chemical to use.
Pay attention to commissioning.
A thorough commissioning plan
is essential to the successful
implementation of a HERO system.
Every control point-such as valvepositions, pumps, and pressure
set points-should be checked.
Sandia's commissioning plan cov-
ered typical construction checks
(e.g., leak tests) and thorough test-
ing of the entire system. First, the
quality of the HERO-treated output
water was checked to verify that
contaminants were removed satis-
factorily. Next, a 2-week test was
conducted to verify that the entire
system functioned correctly.This
test was performed with the water
treatment company that built andinstalled the system on site and
was available for emergency sup-
port. Finally, a 30-day trial of the
system was conducted without any
outside support.
Know the quality of the water
supply. Knowing the quality of the
water that will supply a HERO sys-
tem is important when designing
and operating the system. Sandia's
water supply was harder by 20%-
30% than that used in the design
of its system, and this resulted in
