Boiler Water Treatment Service

A boiler is an essential component of industrial operations across the world, producing steam for use in comfort heating, heating domestic hot water, maintaining accurate temperatures in industrial processes, and many other applications. With such critical uses, it's important that boilers are well-maintained for longevity and reliability.

When it comes to maintaining a boiler to ensure its efficient and long-lasting operation, the two biggest concerns are scale and corrosion:

  • Boiler scale: This is a type of deposit made of materials like calcium, silica and iron. It appears when these impurities, initially found in the water, precipitate out of the water, then concentrate and harden onto the heat transfer surfaces of the boiler. These deposits can be particularly good at insulating and reduce how well heat transfers to the water, making your boiler less efficient. Scale can also slough off the sides and interrupt the flow of water in the tubes, causing overheating or failure.
  • Boiler corrosion: This can come from several sources but often occurs due to a reaction between certain chemicals in the air or water and the metal of the boiler. These elements can cause pits and wear in the metal, eating away at the inner mechanisms. Other sources include acidity in the water or scale that traps corrosive sodium salts against the metal. Corrosion can shorten a boiler's lifespan, reduce its efficiency and cost more to run.

Both of these issues spell trouble for an industrial boiler system, reducing efficiency, raising costs, shortening the boiler's lifespan and contributing to increased maintenance needs. To keep your boiler free of corrosion and scale, you'll need to use the right boiler water treatment equipment and chemicals.

Benefits of Boiler Water Treatment

How Our Boiler Water Treatment Systems Can Eliminate Scale

As mentioned, the accumulation of scale creates an insulating effect. This insulation can ultimately result in the warping and rupture of the boiler tube. Scale can also reduce heat transfer and efficiency, which can lead to an increase in fuel bills.

The Chardon Labs strategy for preventing the formation of scale in boilers includes the implementation of blowdown, a process that limits the concentration of dissolved minerals by maintaining the appropriate concentration cycles through the purposeful draining of feedwater out of the boiler. Feedwater with a lower concentration of dissolved solids is then added to replace the “blown down” water.

Another way in which we treat your boiler feedwater system is by adding chemicals to the water. Our boiler chemical treatment creates a reaction that consumes many of the scale-forming minerals. Water softeners may also be used to remove calcium, iron and magnesium ions from the feedwater.

Our Boiler Water Treatment Company Can Prevent Corrosion

Corrosion in boilers can be classified in one two ways: general and pitting. General corrosion tends to spread over the entire surface of a metal part of a component. Pitting is more harmful of the two. Although it is more localized in its formation, pitting typically causes a higher amount of damage due to a heavier concentration of corrosion in a smaller area. This often results in a more rapid penetration of corrosion that can lead to total part failure.

Our boiler water treatment service for corrosion entails the application of effective chemical solutions. We use sulfite as oxygen scavengers to absorb the high levels of dissolved oxygen that typically accompanies pitting. We also use a variety of boiler water treatment products to effectively disperse precipitated crystals and particulates. This prevents materials from settling and creating insulating deposits that can eventually result in corrosion, as well as thermal stress.

Cost of Boiler Deposits

The two primary concerns for steam boilers are scale and corrosion. When scale deposits form on boiler tubes, they act as an insulator resulting in uneven heat distribution, warped tubes, and wasted energy. Corrosion can cause oxygen pitting in the boiler, steam trap failure, and leaking condensate lines.

Any of these problems can result in failed inspections and costly repairs. Chardon’s full-service treatment program will not only protect the boiler itself but all areas of your steam system which will maximize boiler efficiency and extend equipment life.

This table indicates the relationship between scale thickness on boiler tubes and the percentage of fuel wasted. Scale is the leading factor contributing to a loss of efficiency in your steam boiler operation. Improper chemical treatment that results in scale deposits will substantially increase your fuel costs.

Boiler Treatment Chemicals

Boiler treatment chemicals are the key to solving many of the issues that can slow down or damage a boiler. They can also prevent many of these problems from occurring in the first place.

Typically, boiler treatment chemicals will address the specific characteristics of water that can lead to corrosion and scale.

Here's how they work:

Scale prevention

To keep the calcium carbonate under control, phosphonate chemicals are typically used to inhibit the production of scale. These chemicals can also have a sludge conditioner built in to help prevent solids from settling.

pH control

Too much acidity in boiler water can be damaging to the overall system. A pH neutralizer uses sodium hydroxide to keep the acidity down and protect the metal of the boiler from the corrosive effects.

Oxygen control

Oxygen is a common culprit when it comes to boiler damage. Whether it causes scale buildup or corrosion, it's important to keep the levels of dissolved oxygen in the water down by infusing it with chemicals that break down the gasses.

Foam reduction

If dissolved solids rise to the surface, steam can cause them to foam up and reduce efficiency. Anti-foaming agents can adjust the surface tension of the water to reduce foam.

We carry a full line of boiler treatment chemicals, including:

Scale prevention boiler chemicals

Our scale prevention chemicals use a phosphonate blend to keep scale from forming. These chemicals may also contain extra dispersing polymers, antifoaming agents, sludge conditioners and PTSA tracers to protect against overfeeding.

pH control boiler chemicals

Our pH-controlling chemicals use sodium hydroxide to neutralize acid and raise the pH of the water. They come in liquid and solid formats.

Boiler inhibitors

For an all-in-one solution, we offer boiler inhibitor treatments. The Comp-50 and Comp-F solutions contain sulfite, caustic and phosphonates, with Comp-F offering a food-safe solution. If you're looking for protection from oxygen pitting, BJ-10 is an economical, long-lasting option.

Return-line boiler chemicals

Treating your return line ensures that pressure remains consistent and the metal can better withstand corrosion. We utilize blends with morpholine, cyclohexylamine, amines and ammonium hydroxide to accomplish different jobs. Different line lengths and pressures fit best with specific blends, and food-safe environments may need specific solutions.


Whether you want to take preventative action to keep your boiler working as efficiently as possible or need to change something about your existing water makeup, our boiler treatment chemicals can help get the job done. It's important to select the right treatment for your specific application, and our experts can help with that, too.
