Application of ion-exchange resins for removing sulphate ions …
WebIon-exchange represents a very powerful technology where one or more undesirable contaminants are removed from the aqueous environment by exchange with another substance. The ideal ion-exchange solution for sulphate reduction is one that combines both anionic and cationic resins. WebThe proposed system consists of a set of ion-exchange resins combining cationic- and anionic-exchange stages. Removal of calcium and magnesium using the weakly acid … Web24 mei 2002 · Many treatment methods have been investigated for nitrate removal but only ion exchange, reverse osmosis and electrodialysis are considered to be practical. Of these three methods, ion exchange is the most economical and thereby will be the method selected by most communities. dahmer beaten to death
