LG Chem membrane elements show some resistance to short-term chlorine (hypochlorite) exposure. The free chlorine tolerance of the
membrane is < 0.1 ppm. Continuous exposure, however, may damage the membrane and should be avoided. Under certain conditions,
the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not
covered under warranty, LG Chem recommends removing residual free chlorine by pretreatment prior to membrane exposure.
