Question

what is permutit and ion exchange resins process

Answer 1

permutit process is a process in where hard water containing such as ca++ is filtered through a natural sand called the zeolite. calogen is a trade mark of complex salt ,sodimmetahexaphospate (NapO3)6.calogen ion gives a complex anion.
Ion-exchange resin, (zeolite) exchanges one ion from the water being treated for another ion that is in the resin (sodium is one component of softening salt, with chlorine being the other). ... The following chemical reactions show the exchange process, where X represents zeolite, the exchange material...
