Improved brine recycling during nitrate removal using ion exchange.
Ion exchange technology is currently the best for removing nitrate from drinking water. However, problems related to the disposal of spent brine from regeneration of exhausted resins must be overcome so that ion exchange can be applied more widely and economically, especially in small communities. For this purpose, a novel spent brine recycling system using combined biological denitrification a...
متن کاملnitrate removal from drinking water by point of use ion exchange
background: a laboratory study was conducted to investigate the ability of a special type of strongly basic resin mp500ws for the removal of nitrate from different waters. methods: two different types of point-of-use (pou) devices containing an identical resin were used. mp500ws known as macro porous was used in pou devices for removal of high concentrations of nitrate and sulfate ions from wat...
متن کاملAmmonium removal from aqueous solution by ion-exchange using packed bed natural zeolite
Ammonium removal from aqueous solution by a natural ion-exchange resin was investigated by considering the factors affecting the ammonium-exchange capacity including the zeolites’ particle size, the loading flow rates and the impact of a number of regenerations upon the ion-exchange capacity. The resin column was exhausted by downflow at 10, 25, 50 and 75 bed volume (BV)/h, until effluent ammon...

متن کاملModeling a novel ion exchange process for arsenic and nitrate removal.
Arsenate and nitrate can be removed quantitatively from drinking water by anion exchange. However, if the raw water contains substantial concentrations of sulfate or nitrate, the resin becomes exhausted quickly, and the requirements for regenerant (brine) can make the process unattractive. Previously, we described a modified ion exchange operating procedure for arsenic removal from solutions co...
