Abstract
ⶠAmmoniacal wastewaters fractionation is highly dependent on feed solution chemistry. ⶠpH dominates selective mass transport and nanofiltration rejection coefficients. ⶠFor pH lower than 9.5, there is a concentration of ammonium in the concentrate. ⶠFor pH higher than 9.5, the ammonium rejection coefficients drop to 10%.
