How Blended Water Supplies Impact Water Treatment

No Two Streams are the Same

The source(s) of water supplied to cooling towers, boilers, and processes may vary greatly daily or even hourly.  The impact this has on water systems must be closely monitored to avoid scale, deposits, corrosion, inefficient water usage, and other negative impacts on operational costs.

How Often Should I Test My Water?

Chem-Aqua representatives are frequently asked, “How often do I need to test my water”?  The answer to this question is as varied as the systems that Chem-Aqua treats.  There are a number of factors that go into determining the “best practice” for each facility.  Typically, these factors are:

Deaerator Design and Operation

A deaerator preheats boiler feedwater and removes dissolved gases, especially oxygen and carbon dioxide. These gases are undesirable because they cause corrosion and increase treatment chemical requirements. 

Deaerators operate based on the reduced solubility of dissolved gases as temperature increases. For example, the solubility of oxygen decreases from about five ppm at 150ºF to about two ppm at 190ºF. Virtually all the free carbon dioxide gas is removed by increasing the temperature to greater than 170ºF.

How to Prepare Your Boiler for an Inspection

Periodic boiler inspections are necessary to ensure that all equipment and components are operating safely and properly. When removing a boiler from service, the proper procedures should be used to reduce thermal stress and prevent sludge from settling and “baking on” waterside surfaces.

If a boiler is cooled too rapidly or unevenly, the extreme expansion and contraction stress can cause leaks to develop on rolled tube ends as well as damage firebrick or refractory material. Rapid cooling and draining can also cause any suspended solids in the boiler water to form hard, difficult-to-remove deposits. These deposits not only reduce heat transfer efficiency but could also lead to a false interpretation of the treatment program results.

How Reverse Osmosis Works

Reverse osmosis (RO) produces high-purity water for use in many applications, including low and high pressure boilers, manufacturing processes, cleaning, and ultrapure water systems.  RO offers numerous benefits that can save water, fuel, operating costs, labor, and more.  Understanding how it works will help in the selection, maintenance, and operation of RO systems.
