Deionization is normally referred to the the final processing step in demineralization. Deionization is the complete removal of ions (other than water ions) present in water. A mixed bed of resins can be employed after demineralization to remove the final contaminants. Another method is to employ electrodeionization (EDI) to achieve deionization. Electrodeionization makes use of a combination of ion exchange resins, ion selective membranes and electricity to purify water. The main advantage of EDI systems is that these EDI units do not require chemical regeneration steps, thus avoiding hassles. Our units are the best in the industry as regards the quality of treated water, energy consumption and manitenance. Quality obtained from these units is of very high standards.

The Process of Deionization or Ion-exchange In the context of water purification, ion-exchange is a rapid and reversible process in which impurity ions present in the water are replaced by ions released by an ion-exchange resin. The impurity ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Positively-charged ions are called cations and are usually metals; negatively-charged ions are called anions and are usually non-metals).The following ions are widely found in raw waters:Ion Exchange Resins  There are two basic types of resin - cation-exchange and anion-exchange resins. Cation exchange resins will release Hydrogen (H+) ions or other positively charged ions in exchange for impurity cations present in the water. Anion exchange resins will release hydroxyl (OH-) ions or other negatively charged ions in exchange for impurity anions present in the water. The application of ion-exchange to water treatment and purification There are three ways in which ion-exchange technology can be used in water treatment and purification: first, cation-exchange resins alone can be employed to soften water by base exchange; secondly, anion-exchange resins alone can be used for organic scavenging or nitrate removal; and thirdly, combinations of cation-exchange and anion-exchange resins can be used to remove virtually all the ionic impurities present in the feedwater, a process known as deionization. Water deionizers purification process results in water of exceptionally high quality. Deionization For many laboratory and industrial applications, high-purity water which is essentially free from ionic contaminants is required. Water of this quality can be produced by deionization.The two most common types of deionization are: Two-bed deionization Mixed-bed deionization Two-bed deionization The two-bed deionizer consists of two vessels - one containing a cation-exchange resin in the hydrogen (H+) form and the other containing an anion resin in the hydroxyl (OH-) form. Water flows through the cation column, whereupon all the cations are exchanged for hydrogen ions.To keep the water electrically balanced, for every monovalent cation, e.g. Na+, one hydrogen ion is exchanged and for every divalent cation, e.g. Ca2+, or Mg2+, two hydrogen ions are exchanged. The same principle applies when considering anion-exchange. The decationised water then flows through the anion column. This time, all the negatively charged ions are exchanged for hydroxide ions which then combine with the hydrogen ions to form water (H2O). Mixed-bed deionization In mixed-bed deionizers the cation-exchange and anion-exchange resins are intimately mixed and contained in a single pressure vessel. The thorough mixture of cation-exchangers and anion-exchangers in a single column makes a mixed-bed deionizer equivalent to a lengthy series of two-bed plants. As a result, the water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed plant.Although more efficient in purifying the incoming feedwater, mixed-bed plants are more sensitive to impurities in the water supply and involve a more complicated regeneration process. Mixed-bed deionizers are normally used to ‘polish’ the water to higher levels of purity after it has been initially treated by either a two-bed deionizer or a reverse osmosis unit. Electrodeionization EDI Electrodeionization Systems remove ions from aqueous streams, typically in conjunction with reverse osmosis (RO) and other purification devices. Our high-quality deionization modules continually produce ultrapure water up to 18.2MW/cm. EDI may be run continuously or intermittently

Electro Deionization is a water treatment technology that has gained popular acceptance because the process does not use chemical treatments. In such a system, there are no moving parts. Water is passed between a positive electrode and a negative electrode. Semi permeable ion-exchange membranes separate the positive and negative ions, delivering deionized water. Electro Deionization (EDI) removes ionizable solids 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 exchange in that it does not require the use of chemicals such as acid and caustic soda. In traditional ion exchange units, after the contaminants are trapped onto the resin pores, the resin continues to exhaust and lost capacity. In EDI, the contaminants are continuously removed as they are attracted to one of the two electrical charges, and they migrate through the resin bed, through ion exchange membranes and into the concentrate stream where they are removed from the device.EDI is a polishing technology and requires reverse osmosis (RO) as pretreatment. The combination of RO-EDI provides the customer with a continuous, chemical-free system. Electro deionization systems typically have a life cycle of more than five years. The lifecycle of the system can be prolonged based on the pretreated water quality.

Electrodeionisation or EDI, is a continuous and chemical-free process of removing ionized and ionizable species from the feed water using DC power. EDI is typically used to polish reverse osmosis (RO) permeate and to replace conventional mixed bed ion exchange, which eliminates the need to store and handle hazardous chemicals used for resin regeneration and associated waste neutralization requirements.
