The invention provides methods and compositions for the protection of a membrane from both biofouling and from damage caused by a biocide. The invention utilizes PAA as both a biocide and as a reducing agent for other oxidizing biocides. This is especially beneficial because without the invention one would be forced to choose between preventing membrane biofouling or preventing membrane damage from oxidizing biocides.

Multifunctional method for membrane protection and biofouling control

This disclosure relates to a combination for inhibiting or removing biofouling and a method for inhibiting biofouling growth or removing biofouling. This disclosure also relates to a combination including halogen-type oxidizers, sulfur-containing compounds, and ammonium salts and/or urea. Also disclosed are methods for inhibiting the biofouling growth in a reverse osmosis membrane separation device or nanofiltration membrane separation device or removing the biofouling in a reverse osmosis membrane separation device or nanofiltration membrane separation device.

Composition and method for biofouling inhibition of membrane separation device

The present invention relates to a porous ABPBI (phosphoric acid doped poly (2, 5-benzimidazole)) membrane and process of preparing the same. A stable porous ABPBI (Phosphoric Acid Doped Poly (2, 5-benzimidazole)) membrane stable to acids, bases, solvents and autoclaving is disclosed. The membrane finds use for separation of solutes in solution in acids, bases and solvents.
