About Water - Water Glossary

  • BACTERIA- are single cell microorganisms capable of replicating on their own. They can be divided into two broad categories: aerobic (requiring oxygen) and anaerobic (not requiring oxygen). Bacteria can live in a very broad range of habitats. Some, for example pseudomonads, can thrive in environments containing very low level of nutrients. These bacteria are frequently slime producers and are a major problem in water treatment systems. Other bacteria, which adhere to surfaces, secret gelatinous material which serves to protect the bacteria from chemical disinfectants.
  • BICARBONATE-  is formed in water by the reaction of carbon dioxide with mineral matter, such as limestone or dolomite. The carbon dioxide is absorbed from air or from decaying organic matter, and the bicarbonate that is formed imparts alkalinity to water. See Alkalinity. Calcium and magnesium bicarbonate do not exist in solid form. When water is removed from solutions of these salts, they lose carbon dioxide and form calcium.
  • BRACKISH WATER- Water containing between 1,000 mg/l and 15,000 mg/l of dissolved solids is generally considered to be brackish. CALCIUM CARBONATE Occurs in nature as limestone. It dissolves in water containing carbon dioxide by forming calcium bicarbonate.
  • CALCIUM(Ca)- One of the primary elements of the earth's crust commonly found in water as dissolved solid. The presence of calcium in water is a factor contributing to the formation of scale and insoluble soap curds which are means of clearly identifying hard water. It is sometimes referred to as lime.
  • CALCITE- Calcium Carbonate (CaCO3). A tradename for finely ground limestone, very high in calcium carbonate, which is used to raise the pH of acidic water.
  • CALCIUM BICARBONATE- A salt that is present in most natural waters. Water containing calcium bicarbonate loses carbon dioxide when it is evaporated or concentrated by reverse osmosis and calcium carbonate is precipitated.
