: why gravel bed is laied beneath ion exchange resine. is it ordinary gravel or some special& what should be its thickness?
I currently maintain 2 sodium zeolite ion exchange hot water polishers.
There is no gravel bed beneath the resin. The only gravel bed is in the
salt saturator tank for the regeneration process.
