Water Hardness - an overview | ScienceDirect Topics

Water hardness is handled a little differently from salinity in that in some countries the degree is the unit of measure. One German degree of hardness equals 10mg/liter (ppm) of calcium and magnesium oxide or 17.8ppm of CaCO 3 in the USA. This is not at all equivalent to salinity in that a relatively low salinity water rich in calcium and magnesium could have a relatively high degree of hardness.

F or above to minimize oxygen content. Oxygen content is based on water temperature, so this tank has to be treated for oxygen before the system can mechanically deaerate. At 150°F Sodium Sulfite has limited effectiveness. With low temperatures and high oxygen content, the corrosion rate on carbon steel can be excessive.

Corrosion Control in Cooling Tower Systems Water

Jan 16, 2018 · Cooling water systems are subject to corrosion damage as a result of the reaction of the metal surface with its environment. This environment includes aerated cooling water, scale deposits, surface films, process contaminants, and microbiological growths. These and other conditions lead to rapid deterioration of the cooling tower, heat exchangers and piping system.

Phosphorus - Wikipedia

Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams).

Boiler feedwater - Wikipedia

Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.
