Description
Summary:A continuous counter current (ccc) ion-exchange single column technique is developed and an exhaustive study of water softening is carried out. No operational problems are encountered during field trials of a 40 m 3/h capacity plant for supplying soft water. The plant does not require sophisticated remote control devices, is easy to fabricate, scale up and assemble, and is so simple in operation that it can be managed even by an unskilled worker. Thus it is ideal for underdeveloped countries in spite of known constraints imposed by a single fluidized bed ion-exchange process adopted in its development. Potential savings in ion-exchange resin investment, rinse water requirement and operating cost are estimated by the adoption of this technique in place of conventional water treatment techniques/processes.
