Hi, my name is Amber, and I have worked alongside of contractors for years. I ran the sales department of a contracting firm, I bought my own house and hired multiple contractors to help with projects, and I am an amateur researcher of all things related to contracting. If you are thinking about a home or commercial repair or refurbishment, this blog is for you. It has designs, inspiration and advice that I have picked up from my close relationships with contractors over the year. I hope these posts illuminate your next project and help you decide which direction to take your home or business.

Cooling towers are simply heat exchangers that make use of water and air to discharge heat from HVAC systems to the external environment. More often than not, cooling towers are ignored in terms of maintenance, leading to reduced cooling-system efficiency. Further, health and skyrocketing energy costs also surface. In this regard, here is one of the major steps to help in cooling tower maintenance for facility managers.
Water treatment program
A water treatment program is a crucial step as far as cooling tower maintenance is concerned. It prevents the following:
Mineral build-up
Hard water may be as challenging for water cooling towers as much as it is for users. Because water has the ability to dissolve an array of solids and gases in countless combinations and volumes, lime, calcium among other minerals dissolve in the water. Consequently, they begin to accrue inside the system forming a tough layer of scale within the system.
As a result, the system experiences irregular or low water flow thus decreasing the ability of the cooling tower to cool. Therefore, the water needs to be treated using scale-inhibitor chemicals. Generally, the scale inhibitor is pumped into the cooling tower and as water passes through the tower, it dissolves enough inhibitor to stop scale deposition.
Corrosion
As earlier said, the water passing the cooling tower consists of a lot of dissolved substances including corrosive agents such as carbon dioxide, oxygen and hydrogen sulphide. Therefore, when the water makes contact with the inside of the reservoir, corrosion begins to occur. Once the reservoir starts to degrade, immediate repairs will become compulsory in order for the system to remain effective.
So as to prevent the inside parts of the tower from being corroded, homeowners can add a corrosion inhibitor to the cooling tower water. The corrosion inhibitor converts the corrosive agents into nonthreatening forms. For example, oxygen is converted into water.
Organic compounds
Bacterial growth is a common feature in many water-using platforms such as water cooling towers. Microorganisms make their way in from the makeup line and start to grow within the system. Legionella is a typical development inside cooling towers. This ailment causes a lung infection reminiscent of an uncommon type of pneumonia.
The threat of human contraction of pneumonia at your facility is greater when the water in your tower is left untreated. In order to control these organic compounds, use chemical biocides. These biocides consist of excellent oxidized and non-oxidized constituents which prevent the growth of fungi, bacteria and other microbes.
