Cooling Tower Treatments and Water Quality

Water.  What a unique molecule.

Often called the universal solvent, water’s basic properties make it ideal for cooling towers: it’s safe, widely available, and inexpensive. It’s also an efficient heat transfer medium, especially when compared to air.

But being the universal solvent is a property that can cause unwanted side effects for industrial applications. For example, water can dissolve metals like copper, magnesium, iron and even calcium. When those metals over-saturate the water, corrosion or carbonate scale in cooling systems can occur.

Take control of your cooling tower’s efficiency with proper water treatment by Orenda. It’s preventative maintenance so you have less down-time.

Problems

CORROSION Manufacturing of common metals used in cooling systems–such as mild steel–involves removing oxygen from the natural ore. Cooling water systems are an ideal environment for the reversion of the metal to the original oxide state. This reversion process is called corrosion.

Cooling Tower Treatments

Dissolved metals in water will build up over time. It’s why we see scale and corrosion in places like our sinks and metal pipes.

SCALE Minerals such as calcium carbonate, calcium phosphate, and magnesium silicate are relatively insoluble in water. They can precipitate out of the water to form scale deposits when exposed to conditions commonly found in cooling water systems.

FOULING The deposition of suspended material in heat exchange equipment is called fouling. Foulants can come from external sources such as dust around a cooling tower or internal sources such as byproducts of corrosion.

HEAT EXCHANGER INEFFICIENCY Cooling water systems provide an ideal environment for contaminates to grow, multiply, and cause deposit problems in heat exchange equipment. Macrofouling can occur in once-through cooling systems or water intakes in lakes and rivers. Various species of clams, mussels, and other marine organisms can attach to the piping, reducing water flow and increasing corrosion.

Scale Treatment

Carbonate scale inside a pipe. It’s as hard as a rock and severely limits water flow.

Mineral scale buildup in cooling towers, chillers and system piping is a common challenge for many industrial water systems. Often, the makeup water that enters these systems is “scaling” in nature, causing a buildup of both organic and inorganic material. Left unchecked or inadequately treated, this buildup impedes performance, shortens infrastructure lifetime and increases the consumption of both water and energy.

Along with traditional free chlorine, Orenda’s cooling tower treatment targets and eliminates scale. Our unique formulation is nonhazardous, eco-friendly and safe for all system conditions.

Compared to traditional cooling tower biocides and scale inhibitors, Orenda’s process is fast-acting, easy to handle and cost-effective. It also chemically treats cooling towers while they are still online, eliminating downtime.
