#CMT# #/CMT# Regeneration of sodium alumino-silicate ion exchange material used for binding ammonia involves collecting regenerating solution containing sodium chloride in a reservoir; removing the ammonia content of the regenerating solution by forming magnesium-ammonium phosphate precipitate; performing phosphate formation by adding phosphorous acid and sodium hydroxide or trisodium phosphate or sodium hydrogen phosphate; promoting ion exchange and gas formation by shaking with ultrasound; reducing excess of chlorine by adding ferrous chloride and ascorbic acid; and reducing ferric ions. #CMT# : #/CMT# Regeneration of sodium alumino-silicate ion exchange material used for binding ammonia involves collecting regenerating solution containing sodium chloride in a reservoir; removing the ammonia content of the regenerating sodium chloride solution mainly by forming magnesium-ammonium phosphate precipitate, where the calcium and magnesium content of the salt solution is reduced by phosphate precipitate formation; performing phosphate formation by adding phosphorous acid and sodium hydroxide or trisodium phosphate or sodium hydrogen phosphate; promoting ion exchange and gas formation by shaking with ultrasound; reducing excess of chlorine by adding ferrous chloride and ascorbic acid; and reducing ferric ions using the ascorbic acid in the processes. An independent claim is included for sterilization of sodium alumino-silicate ion exchange material used for binding ammonia either before and after regeneration, where the sodium chloride solution is used. #CMT#USE : #/CMT# For regeneration of sodium alumino-silicate ion exchange material used for binding ammonia; and sterilization of sodium alumino-silicate ion exchange material used for binding ammonia. #CMT#ADVANTAGE : #/CMT# The process is environment friendly. #CMT#EXAMPLE : #/CMT# No suitable example is given. |
