Topics that impact water treatment technologies:
ZERO DISCHARGE/ZERO BLOWDOWN
Many plants and whole industries
have "Closed the loop." Even the pulp and paper industry is very
close to meeting this objective. Water conservation, re-use, reclamation, and
recycling can solve many problems, and conserve cash and fresh water resources.
A water audit, "pinch" technology, and conceptual design can form the
basis for your plans to close the loop.
OUTSOURCING CHEMICAL AND EQUIPMENT PURCHASES
Outsourcing
is a word used to describe a host of cost cutting strategies. Water treatment
chemicals and equipment fall into this category. Proprietary chemical products,
such as those from water treatment service companies, have substantial operating
income margins. Informed outsourcing strategies can provide savings of 30 to
50% on proprietary products. The actual savings potential is site specific, but
savings within this range have been achieved by electric utilities and other
industries.
LEGIONELLA CONTROL/TESTING
Preparation for and control of
the legionnaires' disease issue begins with an informed internal staff. What's
new? What do we need to know? Should we test at all? How often should we
test? What should we test for? What do test results mean? What are we
doing now? Are we doing enough? What else can we be doing? How do we
compare with others concerned with this issue. What's ahead for our cooling
towers?
ENHANCED AND SUPER-ENHANCED CONDENSER TUBES
Condenser tubes
which are finned on the outside, rifled on the inside, or both present special
water treatment considerations. The improved thermal efficiencies of these
relatively new tube designs are making them more and more popular for new AC and
other refrigeration equipment systems. These tubes can be damaged by corrosion
more easily than conventional, smooth tubes. They are more easily fouled by
bio-mass and other undissolved solids than are smooth tubes. If you have
condensers with enhanced or super-enhanced tubes, learn how to benefit from the
improved heat transfer without paying the price for damaged equipment and
unscheduled downtime.
CARBON STEEL TUBES
The costs associated with freon
refrigerants are climbing steadily. One of the alternative refrigerants,
ammonia, is being considered for future use in refrigeration equipment being
designed and installed currently. Since ammonia requires steel condenser tubes,
many of the new machines designed around freon replacements come with steel
tubes. Water treatment for evaporative cooling systems with steel tubes is
crucial. This is particularly true for those industries that
use carbon steel tubed heat exchangers such as petroleum refineries and chemical
plants. Special preparation and passivation procedures, as well as a
consistently applied, specific steel corrosion inhibitor program are essential
ingredients in the design life expectancy of these condensers.
FILM FILL
Cooling tower film fill comes in many design and
material varieties. Some are more prone to fouling or premature degradation
than others, but all types require special consideration of microbiological
application and control programs. Film fill requires wetted, clean surfaces and
open, unclogged passages in order to deliver the thermal and energy efficiencies
designed into it. If you use film fill or are considering film fill as a
replacement for conventional splash fill, we can provide the water treatment
performance perspective.
OZONE & OTHER OXIDATION TECHNOLOGIES
Chlorination carries
with it known environmental and health and safety costs. Alternatives to
chlorine are increasingly in our future, for drinking water disinfection, in
paper and other industrial processes, and for cooling towers. If you are
interested in learning more about the practical use of alternative oxidation
technologies, we can help.

SIDE STREAM SOFTENING
Increasing costs for fresh water and
tighter restrictions on water discharges are two good reasons for side stream
treatment of evaporative cooling system water. These days softening means
a lot more than chemical softening or ion exchange. New water treatment
technologies offer innovative ways to get more evaporation out of every gallon
of make-up.
REVERSE OSMOSIS AND OTHER MEMBRANE TECHNOLOGIES
Membrane
technologies are one of the fastest, most flexible in the water treatment field.
Regenerant waste requires treatment, and increased demineralization capacity is
expensive. Reverse osmosis and other treatment processes that do not use
hazardous regenerant chemicals can minimize your liquid waste problems and increase
the capacity of your existing ion exchange plant. We can show you how.
WHITE RUST
White Rust is the name given to the corrosion
of galvanized steel cooling towers and evaporative condensers. The useful life
of galvanized cooling towers depends on a corrosion prevention program which
begins before the cooling tower is put into service, and preferably even before
it is set in place.
