It then becomes necessary to control the environment artificially by supplying supplemental oxygen. Oxygen, as air, is introduced either by mechanical agitators or by blowers and subsurface aerators. Because energy must be expended, the efficiency of the oxygen transfer is a consideration.

Water Hardness - Water Quality Parameter Overview | Hach

Water is essential to metal and mining operations, but the industry is seldom the only consumer of water near extraction or processing sites. By monitoring and treating source water, mining companies not only ensure their own quality standards are met, but they also can contribute to the health of communities, agricultural resources and wildlife ecosystems in the process.

Corrosion Plumbing Piping - PHCP Pros

Dec 05, 2016 · Low pH Acidic water, with a low pH (below 7 on the pH scale), can cause corrosion. The lower the pH is, the more aggressive the water can be. Water with a higher pH can increase the electrical conductivity of the water allowing galvanic corrosion to occur if dissimilar metals are directly connected. Generally, the ideal pH is slightly above 7.

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).
