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 them:

Bacterial Growth

Bacteria, fungi, algae, viruses and other contaminants thrive in the cooling tower's hot and humid environment. Biological contamination can lead to serious concerns, such as corrosion of the cooling tower surfaces, fouling of interior surfaces and diseases affecting those who live near the cooling tower site.

Chardon takes these steps to address bacterial growth in cooling towers:

  1. A water treatment specialist collects water samples.
  2. The sample will be analyzed to identify the type of biological contamination.
  3. A cooling tower chemical treatment plan is created based on the results.
  4. Throughout the treatment process, the specialist will collect and analyze more samples to determine the effectiveness of the treatment plan.

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.


Chemical reactions like corrosion cause materials to wear away over time. Corrosion, in turn, can cause further problems, such as metal debris and contamination, leaks within the system and costly equipment damage.

Since corrosion progresses when water conductivity increases, a specialist can recommend various corrosion treatment options, including:

  • Lay a layer of epoxy: Epoxy coating acts as a barrier between the cooling tower's metal surfaces and the water, which can help prevent corrosion.
  • Protect surfaces with corrosion inhibitors: Chemical inhibitors in the water can help prevent the chemical reactions that lead to corrosion. Inhibitor options include anodic corrosion inhibitors like orthophosphate and cathodic corrosion inhibitors, including polyphosphate and zinc.
  • Manage your pH levels with a multi-step approach: Since high pH levels can cause corrosion, specialists can manage the pH levels to bring it to neutral levels.


Scaling is the mineral buildup of calcium carbonate and other calcium salts from water hardness. This buildup can cause an array of problems with your cooling tank. The thin scale pieces can damage the cooling tower tubes and reduce the overall system efficiency.

If scaling is present in your cooling tower, Chardon will remove it using a cleaning process to make your system efficient again. For a preventative approach, a water treatment specialist will use processes like:

  • Conductivity monitoring: The conductivity monitoring process quantifies the amount of calcium buildup in the system. The specialist will make sure the cooling water's conductivity range is within parameters that will prevent buildup.
  • Chemical monitoring: Chemical monitoring regularly assesses the dissolved chemical levels in water to ensure levels do not exceed solubility limits. We will adjust treatments as needed to control the mineral levels.
  • Blowdown removal: The blowdown removal process removes water that has high mineral concentrations in cooling towers to prevent scale formation.

Cooling Tower Classifications

Cooling towers can range in size from fairly modest to extremely large, depending on the cooling loads of a facility. Several types of cooling towers exist, and they're classified by:

  • The direction of the airflow.
  • The position of the fans.
  • The use of mechanical fans.

Specific classifications include:

Draft Types

Cooling towers use natural or induced draft to provide convection for the system and move air throughout the tower. The most common draft types include:

  • 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. Since the air exits the tower at a high velocity, the air is far enough removed to prevent it from recirculating in the system.
  • 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.

Airflow Types

Airflow in a cooling tower refers to how the air moves through the system. The main airflow types include:

  • 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 and the large surface area of the spray volume produced. These towers typically have a smaller footprint, reduced pump head requirements and greater freeze resistance than crossflow versions.
  • 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. Other advantages include simple maintenance, smaller and efficient pumps and more variable water flow. Crossflow towers also include gravity-fed water decks with openings to allow water to fall through and spread across the tower fill below.

Air and Water Contact Types

Cooling towers differ in whether they allow contact between air and water. The main types include:

  • Open loop: In an open loop design, the same water is used to cool and generate an evaporative cooling effect, which decreases the salt concentration in the water. The water is open to the atmosphere.
  • Closed loop: The closed loop design does not expose the cooling water to the atmosphere. An external circuit uses cooling water as a spray to produce a cooling effect. An internal circuit transfers heat via heat exchangers. The advantages of a closed loop system include keeping the process fluids clean and separated and cooling fluids at a higher temperature.

Cooling Tower Service Procedures

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.

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.
