tem runs continuously at a higher
flowrate than the primary system to
maintain velocity to the piping distribution
loop and laterals that provide
water to all factory points of use.
Ramifications of water impurity
Depending on the intended use for
high-purity water and the industry,
the consequences of water impurity
are significant. For the medical,
pharmaceutical or personal-care
industries, poor water quality can
put a patient's health at risk, result
in plant shutdowns or cause important
drug products to be destroyed.
Furthermore, the usage and lifespan
of medical equipment and laboratory
testing relies on high-purity water. It
can impact the longevity of equipment
and potentially skew results
or disrupt testing practices. Impure
water can lead to issues with medical
devices and test results in laboratories,
which can lead to costly replacements,
equipment downtime or
delays in care.
Manufacturing and microtechnology
rely on ultrapure water to make
sure the smallest pieces of electronics
and technology run as they
should. Issues with impure water
can cause disruptions in manufacturing,
costing the manufacturer time
and resources to solve the problem.
Furthermore, it exposes the manufacturer
to possible widespread
product defects and recalls, depleting
resources even further.
Servicing a UPW system
Proactively avoiding issues with a
water purification system is just as
important as selecting and installing
the system in the first place. A wellplanned
and maintained system is
extremely important to protect both
the manufacturer and the end user.
Ultimately, the manufacturer is responsible
for establishing the specific
water-quality standards that
it needs to build into its process to
ensure the water being used meets
industry and safety guidelines. As a
result, manufacturers often look to
water-treatment technology providers
to understand water standards
and assist with system design, installation
and ongoing service
to
maintain water quality and reliability.
Since a water-purification system
is as complicated as it is important,
requiring a sophisticated knowledge
base encompassing mechanics,
physics and chemistry, partnering
with an expert can prove to be very
valuable. To ensure that high-purity
water flows without any problems,
a service provider should offer an
understanding on meeting waterpurity
industry standards, know-how
to design and build an appropriate
water-treatment system and have
the capability to provide timely and
reliable maintenance and repairs. ■
