Removal of Mineral Salts
Demineralisation is the process of removing mineral salts from Water by using the ion exchange process. Demineralised Water is Water completely free (or almost) of dissolved minerals. The definition of demineralization is that all the minerals in the water, which consist of positive and negative ions, are removed, leaving pure water (H20) molecules or trace amounts of these ions (Oxford, 2015). The positive ions are defined as cations and may include magnesium, sodium, calcium, iron and copper. The negative ions are referred to as anions and may include chlorides and sulphates. The conductivity of demin water for power generation is typically around 0.055 µS/cm. At this conductivity, it will not conduct energy electrical currents through it.
Product Function
A Typical two-bed DM Water Plant consists of two FRP/MSRL/SS Pressure vessels connected in series along with its internal fittings. The first unit consists of high capacity strong acid cation (SAC) exchange resin, which replaces positive ions of salt with hydrogen ions to form respective acids, which are absorbed in the next vessel by strong base anion (SBA) exchange resin.
Cation Exchange Resins And Anion Exchange Resign
There are two general types of ion exchange resins: those that exchange positive ions, called cation exchange resins, and those that exchange negative ions, called anion exchange resins. A cation is an ion with a positive charge. Common cations include Ca+2, Mg+2, Fe+2, and H+1. A cation resin is one that exchanges positive ions. An anion is an ion with a negative charge. Common anions include Cl-1, SO4-2, and OH-1. An anion resin is one that exchanges negative ions. Chemically, both types are similar and belong to a group of compounds called polymers, which are extremely large molecules that are formed by the combination of many molecules of one or two compounds in a repeating structure that produces long chains. A demineralizer is a vessel, usually with a volume of several cubic feet that contains the resin.
