Old & simple Method of How to Clean Rust Stains

Chemically, acids are the preferred way to remove rust stains. Rust stains which come from iron in the water supply, can only be permanently remove through installation of an iron filter.

pH, Total Dissolved Solids, Turbidity, and Warter polusion

It the pH of water is less than 7.0, it is acidic and if it is greater than 7.0, it is considered basic. Water with a pH of exactly 7.0 is considered neutral. If pH values deviate very far from neutral, other water quality problems may be indicated.

Classes of water pollutants

Although some kinds of water pollution can occur through natural processes, it is mostly a result of human activities. The eight classes of water pollutants are inorganic chemicals, organic chemicals, oxygen depleting wastes, infectious agents, plant nutrient pollutants, sediments, radioactive materials, and thermal pollution.

Auto Corrosion, Contact Corrosion, & Externally Induced Corrosion

The most commonly occurring types of corrosion are Auto and Contact corrosion. Auto corrosion occurs when a metal is in contact with an electrolyte. But at the same time, it is not in contact with any other electrical conductor, neither metallic nor non-metallic.
