Lewatit® MonoPlus SR 7 is a macroporous, polystyrene base, monodisperse, nitrate selective anion exchange resin. Lewatit MonoPlus SR 7 has three times the selectivity for nitrates of any commercially available anion exchange resin, which enables it to remove nitrates from sulfate-bearing waters without the danger of nitrate dumping. Dumping occurs in other resins when the nitrate capacity is exhausted and sulfate ions push nitrate ions off the active sites. When this occurs, the effluent with contain more nitrate than the influent. Lewatit MonoPlus SR 7 is ideal for small municipal systems and residential point-of-entry and point-of-use cartridges, because these have a tendency to be overrun and cause nitrates to be dumped. Lewatit MonoPlus SR 7 has been specially prepared to meet drinking water standards and has passed taste and odor tests. Leatit MonoPlus SR 7 is especially suitable for the following applications:- the removal of nitrate from drinking water
- the removal of nitrate from waste water
- the removal of nitrate from aquarium and fish farming water
- the removal of nitrate from water
- the removal of iodide from water
- the removal of chlorate from concentrated NaOH
