All of our products and equipment are top of the line to ensure the highest quality and compliance to fit your specific water system treatment needs. By addressing the following areas, a complete water treatment program can be achieved:
Corrosion
Corrosion is an electrochemical process by which metals return to their
natural oxide state. Most metals used in water systems will corrode to some
extent, some more severely than others. The rate of general corrosion, or
the rate at which metal is lost equally across the surface, is normally
a function of the water chemistry. The rate of localized corrosion (pitting,
under deposit, crevice type, etc) is primarily a function of the localized
environment created by deposits, microorganisms, or structure, in addition
to the water chemistry. Localized corrosion is of most concern and responsible
for premature failure of equipment.
Scale
Scale is formed in water systems when sparingly soluble salts such as
calcium carbonate exceed their solubility limits. This occurs due to the
concentration of these salts by evaporation and by reduced solubility at
heat exchange surfaces. These deposits will result in increased energy consumption,
higher production costs, and localized corrosion. It is also important to
note that many municipalities are now adding phosphates to the city water
for corrosion control which can also concentrate in your water systems and
lead to calcium phosphate deposition.
Microbiological fouling occurs when biofilm (bacterial, algal, or fungal)
interferes with flow or heat transfer. Excessive biofilm can trap and entrain
debris making a bad situation worse. Bio-fouling generally occurs in the
low flow areas first but will also occur in higher flow velocity areas as
well. Deposits formed as a result of fouling can also create localized corrosion.
Bio-fouling problems often occur due to long term neglect or in certain
areas within complex water systems that may experience low flow velocities.
A system may be well treated yet experience bio-fouling in localized areas
due to environmental conditions unique to that part of the system.
Overall fouling occurs by outside containments, (such as dust, dirt,
grim and other particles) getting into your water system. Knowing this,
it is important to make sure proper treatment is used to keep these particles
free-flowing to eventually end up in the “bleed off” of the system. If not
treated, these particles can attach themselves to heat transfer surfaces
and create an increase in energy demand with a decrease in efficiency. Additionally,
these particles can also create an increase in localized corrosion and biological
fouling. Some systems may require an additional means of filtration to “scrub” these
particles out of the system.
Biofilms can harbor organisms which can cause disease. The most well
known of which is Legionnaire’s Disease caused by certain species of the
genus Legionella and primarily Legionella pneumophila. This particular organism
can cause a fatal pneumonia like illness in susceptible individuals when
significant numbers of infectious organisms are inhaled into the lungs.
These organisms do not amplify (multiply) in the bulk water but do so in
the biofilm community where other organisms provide this genus with necessary
nutrients required for growth. These organisms, when present in high numbers
in biofilm, are shed into the bulk water and aerosolized with the cooling
tower drift where they can be inhaled by passersby.
