Free chlorine tolerance |
<0.1 ppm b |
a When pH > 10,the maximum allowable temperature for continuous operation is 95℉（35℃）.
bUnder certain conditions, the presence of free chlorine and other oxidants willlead to premature failure of membranes. Therefore, it is recommended that themembrane be pretreated to remove residual free chlorine before water comes intocontact with membranes.
E-MEM residential membrane components are mainly used in various household water purifiers, mineralized direct drinking machines hospitals, laboratory, other small systems.
