What is condensate?

When airborne water vapor, which is frequently referred to as humidity, makes contact with a colder surface, the water transforms into a liquid and gathers on the cold surface.

Condensate is the name for the liquidized water vapor in the air. In order to reintroduce the condensate water to the steam cycle, it is combined with demineralized municipal “makeup” water.

What is condensate

Why do we need filtration for condensate?

Water is an effective solvent that can dissolve the surfaces of piping and equipment, particularly those in boilers and condensers. Demineralized water, in particular, is utilized in high-pressure, high-temperature boilers.

The cleanliness of the water has a significant impact on how much condensate return water can be recycled into the steam cycle.

Every time the condensate water passes through the steam cycle of the boiler, the concentration of pollutants, such as dissolved solids, hardness, alkalinity, chlorides, and silica, rises. Scale, corrosion, and equipment plugging are caused by these contaminants.

Lower heat-transfer efficiency, leaks, equipment breakdowns, and potential safety concerns are all consequences of the system’s deterioration.

A portion of the boiler feed water, which includes condensate return water, is “blown down” (removed) from the boiler during the steam cycle in order to regulate the boiler’s chemistry and manage the pollutants and dissolved solids’ rising concentration.

Blowing down impure water aids in cleaning the steam cycle by removing salts, metals, oils and greases, and other impurities, but it also increases the quantity of demineralized makeup water that must be fed to the boiler.

An effective industrial water treatment system includes a condensate polishing system at this point.

The polisher cleans the condensate return water of impurities, which reduces scale, improves heat transfer efficiency, lessens the risk of pollutants harming expensive boiler equipment, and increases the volume of condensate return water that can be reintroduced into the steam cycle.

What are the various options for treating condensate?

Condensate filter demineralizers, condensate polishing, and condensate filtering using disposable or back-washable septa. Every method has benefits and drawbacks.

What’s the benefit of condensate filtration?

Using a condensate polishing system to filter water is a smart move that can result in enhanced boiler equipment performance, controlled water, electricity, and chemical costs, as well as significant financial benefits.

  • Extended equipment service time
  • Improve production efficiency
  • Reduction of the water and energy, more environmentally-friendly
  • Less chemical consumption


Condensate is an important part of the whole power generation process. When we utilize a good filtration system for condensate, productivity can be significantly improved and energy loss can be reduced.

Using an appropriate condensate filtration system to some extent is very economical.
