Solutions to Common Contaminants

Biological contamination, surface corrosion and mineral buildup are a few common problems that necessitate cooling tower chemical treatment. Explore the reasons these issues occur and how specialists can solve these issues.

  • Bacterial growth: Bacteria, fungi, algae and other contaminants thrive in the cooling tower's hot and humid environment. A water treatment specialist can collect water samples and create a cooling tower chemical treatment plan based on the results. After flushing and refilling the tower with fresh water, you can retain that purity by using the right cooling tower water treatment chemicals to prevent biological contaminants.
  • Corrosion: Chemical reactions like corrosion cause materials to wear away over time. Since corrosion progresses when water conductivity increases, a specialist can recommend that you create a barrier with a layer of epoxy, protect surfaces with corrosion inhibitors and manage your pH levels with a multi-step approach.
  • Scaling: Mineral buildup from water hardness causes an array of problems with your cooling tank. A water treatment specialist prevents scaling through processes like conductivity monitoring, chemical monitoring and blowdown removal.

Cooling Tower Water Treatment

Cooling towers can range in size from fairly modest to extremely large, depending on the cooling loads of a facility. Several versions exist, and they're classified by draft type, which can be natural or mechanical, and airflow direction, which is either counterflow or crossflow:

Mechanical draft

These towers operate via a fan located at the base or top of the unit. The former is referred to as a forced draft tower, while the latter is known as an induced draft tower. The forced draft version propels air through the water spill area and expels it through the opening at the top. Induced draft towers use the fan to draw air upward as warm condensed air spills downward.

Natural draft

Unlike their mechanical draft counterparts, these cooling towers do not use fans to push air out of the tower. Instead, they rely on the principle of differing densities. The warm air within the tower's chimney structure rises because its lower density draws the cooler air to the bottom. Natural draft towers tend to be taller and have a hyperbolic shape to produce adequate airflow.

Counterflow towers

A counterflow tower derives its name from the countering action of air flowing upward and water flowing downward. The result is excellent thermal efficiency due to the coolest air contacting the coolest water in the bottom of the unit. These towers typically have a smaller footprint than crossflow versions as well as reduced pump head requirements.

Crossflow towers

As the name implies, these towers facilitate horizontal airflow across the water as it falls to the bottom of the unit. The result is lower airflow resistance, which significantly reduces fan horsepower requirements. Crossflow towers also include gravity-fed water decks with openings to allow water to fall through and spread across the tower fill below.

“We don’t sell chemicals, we sell clean systems.”


When it comes to cooling tower water treatment, Chardon handles them all and will tailor a maintenance program to meet your specific needs. We'll work closely with your team to provide a cost-effective solution based on the type of cooling tower equipment you use at your facility. As an ISO-certified company, we can complete high-quality work that exceeds your expectations.

Due to its exposure to the outside environment, the cooling tower is the primary source of contamination within your system. Acting as a large air washer, the “open” tower water loop accumulates airborne particulate and promotes biological growth. Through evaporation, it also concentrates mineral content.

Chardon utilizes a full line of corrosion and scale inhibitors, white rust preventatives, and microbiological inhibitors to create a custom chemical plan that addresses these problems and others to keep your cooling towers running efficiently.

Because we don't sell these cooling tower water treatment chemicals, we have a shared interest to keep your system's operating costs as low as possible. We offer our services at an affordable, guaranteed annual price to fit your company's budget. With our transparent pricing structure, you'll never have to worry about hidden fees or add-on expenses driving up costs.

Overview of Our Cooling Tower Water Treatment Products

Our advanced cooling tower water treatment services include the precise utilization of our superior cooling tower inhibitor product line. We have developed products that are specifically designed to treat each specific condition that could lead to contamination.

For instance, some products will eliminate scale in cooling towers with hard, alkaline make-up water, while others will prevent corrosion in systems with soft or low TDS make-up water. Our well-trained, experienced ISO-certified technicians have the expertise to select and apply the right water treatment chemicals for your unique cooling tower maintenance requirements.

Water Treatment Equipment                                    For Cooling Towers

conductivity controller from advantage controls

Keeping an effective cooling water treatment program in your cooling tower requires calibrated and functioning treatment systems. Upgraded and state of the art equipment can help maintain your cooling tower longer, as well as decrease cost of water treatment. Finding proper chemical feed by use of a contact-head water meter, or using a more reliable bleed solenoid can help prevent potential issues.

At Chardon, we offer a selection of cooling tower equipment and treatment solutions that will help maintain the tower and the system as a whole. Proper equipment is a must in order to not only prevent scale and corrosion but microbiological growth as well. Having a proper biocide feed into the system is necessary to prevent harmful bacterial growth such as Legionella from becoming a problem.

Cooling Tower Chemicals For Water Treatment

Chemically treating your cooling systems is an essential part of maintaining and improving your system efficiency and keeping it fully operational. Not to mention the savings you'll have from less water usage and less downtime. Chemical treatments also provide a safe solution, assuming you choose the right product for the specific issue you're experiencing and apply it correctly.

Ultimately, treating your cooling tower water with the appropriate chemicals can help control scale, corrosion, algae and harmful bacteria like Legionella Pneumophila.

We have a variety of cooling tower chemicals that you may need for your treatment programs:

Corrosion Inhibitors and Protection

These chemicals help eliminate rust and scale, two of the most common issues that can hinder the performance of your cooling tower equipment and shorten its lifespan.

Non-Oxidizing Biocides (for specific systems and forms of biological growth and bacteria)

These anti-bacterial chemicals can rectify cooling tower water issues such as biological growth, inferior quality, toxicity and improper pH levels.

Oxidizing Biocides (variety of Chlorine and Bromine)

These biocides rely on an electron transfer reaction to attack microorganisms in cooling tower water. Their benefits include simple disbursement, easy measuring and hassle-free control.

Anti-Foaming Chemicals

Cooling tower water is prone to foaming due to the overfeeding of biocides and similar issues. Anti-foaming chemicals help to eliminate excess foam in the system.

Pre-Treatment Chemicals

Pre-treatment of cooling tower water systems is essential for maximizing the lifespan of heat transer equipment. We offer chemicals that enable the execution of the two phases of pre-treatment: pre-cleaning (removing foreign matter) and pre-filming (promoting the formation of an inhibiting film).

How Cooling Tower Chemical Dosing Works

Cooling tower chemical dosing systems control bacteria and microorganisms by pumping out cooling tower water treatment chemicals in measured amounts. If you avoid maintaining and treating your cooling tower, you reduce productivity, risk downtime and require expensive equipment replacements more often.

The most common types for industrial or commercial use are diaphragm dosing pumps. These cooling tower chemical treatment systems regulate alkalinity, chloride, iron and other levels within cooling tanks. An automated chemical pump provides consistent cooling tower chemical dosing. When selecting a dosing pump, it's vital to consider pressure rating, output capacity and other control functions.
