WebExhaust the resin with raw water by passing 6 BV of 2% CaCl2 solution at a flow rate of 2 BV/h = 2.2 eq/l. Rinse with 5 BV of DI water at a rate of 2 BV/h. Regenerate the resin by passing 2 BV of 10% NaCl at a rate of 2 BV/h. Rinse with 5 BV of DI water at a rate of 2 BV/h. Repeat the above process at least once. WebTreated water leaving the column flowing downwards then comes in contact with this resin last and undergoes the highest possible degree of exchange. 2.3 Advantages and Disadvantages in the use of Ion-Exchange Resins The advantages of ion exchange processes are the very low running costs. Very little energy is required, the regenerant …

WebThe applications of WAC resin in water treatment include: • Removal of alkalinity from water - the process is called dealkalisation. • Treatment of water containing a high proportion of alkaline salts in relation to neutral salts - the weak and strong acid resins can be used either in separate vessels or in the same vessel (layered bed). WebThe general regeneration procedure for ion echange vessels is as follows: Backwash resin bed (co-flow regeneration only) to remove suspended solids and decompact the bed. Inject regenerant diluted in appropriate water quality. The injection is at a low flow rate, so that the contact time is 20 to 40 minutes. clothing tees

WebJun 8, 2024 · In Blog. Ion Exchange (IX) is a reversible chemical water treatment process for selective removal of charged inorganic species from water using an ion-specific resin and replacing them with other similarly charged ions. As water containing undesired ions passes through a column of resin media, charged ions on the resin surface are exchanged ... WebElectrodeionization ( EDI) is a water treatment technology that uses DC Power, ion exchange membranes, and ion exchange resin to deionize water. EDI is usually a polishing treatment to reverse osmosis (RO). EDI differs from other RO polishing technologies such as chemically regenerated mixed beds, in that it is continuous and requires no ...
