The ERO membrane element from SPECTRUM boasts both excellent average rejection rates (98%) plus the ability to operate at very low (3.6 bar) pressures, resulting in some of the best performing membranes available.

ERO-1812 (98% @ 3.6 bar)

For absolute economy, the new spectrum ERO membrane will deliver the same high water quality at a 20% reduction in flow vs. the standard SPECTRUM 1812 SRO membrane. Similar to all other membranes increasing the incoming flow rate will increase permeate and concentrate flow production.
