1Water softening — A water softener reduces the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in hard water.These hardness ions cause three major kinds of undesired effects. Most visibly, metal ions react with soaps… …
2water softener — any of a group of substances that when added to water containing calcium and magnesium ions cause the ions to precipitate or change their usual properties: used in the purification of water for the laboratory, and for giving water more efficient… …
3Dealkalization of water — The dealkalization of water refers to the removal of alkalinity ions from water. Chloride cycle anion ion exchange dealkalizers remove alkalinity from water. Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like …
4Electrodeionization — (EDI) is a water treatment process that removes ionizable species from liquids using electrically active media and an electrical potential to effect ion transport. It differs from other water purification technologies such as conventional ion… …
5New production — In biological oceanography, new production is supported by nutrient inputs from outside the euphotic zone, especially upwelling of nutrients from deep water, but also from terrestrial and atmosphere sources(as opposite to regenerated production,… …
6Nitrogen cycle — Schematic representation of the flow of nitrogen through the environment. The importance of bacteria in the cycle is immediately recognized as being a key element in the cycle, providing different forms of nitrogen compounds assimilable by higher …
7F-ratio — In oceanic biogeochemistry, the f ratio is the fraction of total primary production fuelled by nitrate (as opposed to that fuelled by other nitrogen compounds such as ammonium). This fraction is significant because it is assumed to be directly… …
8fibre, man-made — Introduction fibre whose chemical composition, structure, and properties are significantly modified during the manufacturing process. Man made fibres are spun and woven into a huge number of consumer and industrial products, including… …
9chemical industry — Introduction complex of processes, operations, and organizations engaged in the manufacture of chemicals and their derivatives. Although the chemical industry may be described simply as the industry that uses chemistry and… …
10ion-exchange reaction — ▪ chemical reaction Introduction any of a class of chemical reactions between two substances (each consisting of positively and negatively charged species called ions (ion)) that involves an exchange of one or more ionic components.… …
