MCR17 – nitrate removal ion exchange resin

Macroporous strong base anion exchange resin

MCR17 is a Macroporous strong base anion exchange resin with polystyrene matrix and triethylamine group. MCR17 is designed for nitrate selectivity.

The particle size is in standard gaussian distribution with 0.315-1.25mm >95%.

MCR17 shows a high selectivity to nitrate and an excellent regeneration efficiency.

MCR17 is working above pH>5, and regenerated by 8-10%NaCl.

In USA and Europe, nitrate in drinking water is requested less than 1ppm. MCR17 is designed for the reasonl to remove nitrate and nitrite less than ppb level from underground water, tap water, lake water source.
