Water Boiler Treatment Methods
Water boilers are designed to efficiently heat water in a hot water tank before it is cycled around to where it is needed in the house. Water boilers work best when water is pure and free of any contaminants. Unfortunately, not much water is this clean, especially water that comes from wells and other alternative sources. To properly clean this water, manufacturers create several different methods to treat the water used in boilers.
External treatments are designed to help clean water before it gets to the boiler at all. These systems are used when the water is dirty enough to harm the boiler easily through constant use. There are many methods used in external treatment, but some of the most common are evaporation and deareation, where water is turned into steam and back into water to purify it.
Bacteria tends to grow inside the heated conditions of boiler tanks. This type of bacteria can survive in heated conditions and tends to produce harmful contaminants like sulfur and iron. These bacteria are very difficult to fully remove. Owners need to flush the entire system, clean it out, and remove any components that are heavily invested with the bacteria.
Corrosion occurs when the water rusts the pipes and tank the boiler uses. This type of corrosion is encouraged by two different factors, oxygen in the water and acidic water elements. Corrosion treatments use filters to remove oxygen (air) from the water, and chemical additives to add alkalinity, helping reduce the effects of acidic water.
Scale is the layer of minerals that form on tank surfaces and pipe interiors due to dissolved minerals in the water. Most boilers have rods made out of magnesium or a similar material: these rods attract dissolved minerals and bond them to the rod instead of letting them precipitate out of the water in the heat.
