solids, one to reduce corrosion rates, one to keep the solids from scaling up in the chiller and one or
more to reduce the bacterial levels and it relies on blow down to remove any dissolved solids. A
filtration system is the only system that can physically remove solids from the tower water and
most chemically treated systems do not use filtration. The types of chemicals and amounts vary by
the type of system being treated, the season, the external sources of particulate, the type of bacteria,
the temperature, and on and on and on. Normal cooling towers utilize a basin (water storage site),
cooling media (normally called fill, this normally plastic structure allows water to drain down it
surface while air is passed through the fill to cool the water, a pump to move the water up above the
fill to the spray nozzles that distribute it equally over the fill and a fan to force air through the fill.
Conductivity: Conductivity is defined as the ability of an aqueous solution to carry an electric
current and can be easily measured by a conductivity meter. It is used to estimate Total Dissolved
Solids (TDS). CHC has used several types of Conductivity meters in the past. Walchem WCT
series is the most common, while we have also used the LMI brands or utilize the CCS.
Corrosion - Most metals used in cooling water systems are very susceptible to corrosion. Keeping
surfaces clean is the most important aspect of preventing corrosion, since under-deposit corrosion
can take place and result in serious damage. Corrosion can be uniformly distributed throughout the
system or it can be localized, causing severe pitting and rapid equipment failure. There are various
corrosion inhibitors used in chemical treatment.
Customer Service Report- This report is the record of what service was conducted at the
customer’s site. In most cases the customer will be given a copy of this report at the time of
service. The report is then completed with any appropriate test results (Dip Slide Test), any
appropriate comments and then sent to EcoWater CHC at the end of the week for processing. A
Service Order will be completed at EcoWater that will include any Water Analysis results and
recommendations for continued service in the future. The Service Order will be sent to the
appropriate personnel with any recommendations for modifications.
Customer System Survey- A Customer Survey is a report that is completed at the time of a
monthly or quarterly service that is a detailed listing of the equipment at the customer site as well
as specific application information that is needed to identify equipment or usage. It is a good idea
that as pumps are replaced or piping modified that this survey is updated. If allowed pictures are
worth a thousand words and will make identification of system parts much easier, but always verify
with the customer before any pictures are taken, if pictures are even allowed. This report is sent to
EcoWater CHC to ensure appropriate system information for phone support and other reporting
needs.
Cycles of Concentration- It is a comparison of the concentrations of dissolved salts in makeup
water and basin water. Because of evaporation, H
2
O left water to evaporate and leave the dissolved
salts in cooling water. So the concentration of the dissolved salts in the cooling tower water will
increase. Cycles of 2 means the concentration of certain species (like sodium or chlorides) in the
cooling tower water are 2 times the concentration in the makeup water. As cycles increase the less
make up water is required to maintaining the water level because there is less blow down and more
water remaining the tower basin. Higher CoC are helpful to control bacteria levels.
Descaler- Descalers are chemicals that are used to dissolve scale for cleaning purposes. EcoWater
uses the Rydlyme product.
