Use of combined filters consisting of several layers of fibrous ion-exchange materials alternating with layers of granulated ion exchangers increases the service life of the chemisorption process by almost two times. The use of “bulk” filtering layers consisting of layers of Nitron-C fibre and an ion-exchange fibre web ensures a high degree of removal of both dissolved substances and finely disperse suspensions from industrial wastes. The flow resistance of the treated wastes increases slowly in time, which ensures prolonged work of the filters without washing and regeneration.
