Performance values for all but two cleaners (L212 and P911) fell into the normal ranges

established for the control samples . . . the membrane samples soaked in L212 and P911actually improved.

-Avista Technologies Report October 2010

Conclusion: QuantumFlux ES membranes can withstand the same chemicalcleaning procedures as competing membranes.
