TriSep offers five versions of it's popular ACM series reverse osmosis membrane elements. The ACM line is the workhorse of theTriSep RO line. It delivers high flux and high rejection in a durable and economical membrane. The membrane has a good combination of chemical resistance and mechanical strength. This is exhibited by wide operating pH ranges (2-12), some resistance to oxidants such as chlorine (up to 2,000 ppm-hrs) and hydrogen peroxide, and pressures up to 1,000 psi (70 bar) with the proper construction

ACM1 Elements	99.5% rejection, for high TDS feedwaters
ACM2 Elements	99.5% rejection. Most popular membrane
ACM3 Elements	Lower pressure , same rejection
ACM4 Elements	Low pressure, 99.2% rej.
ACM5 Elements	Ultralow pressure, 98.5 % rejection.
