A reclosable storage bag and zipper tape for use in conjunction with same is disclosed. The reclosable bag includes first and second panels which are sealed about bottom, left, and right edges leaving an open top. The closure system further includes first and second closure assemblies or zippers which can be individually or simultaneously closed to seal the contents within the bag. Even after the first and second zippers are engaged thereby closing the bag, excess air within the bag can be removed simply be manually compressing the bag and thereby forcing the air through the vent apertures provided between the zippers. A valve internal to the closure system may be provided proximate the vent apertures and open upon sufficient application of pressure thereby allowing for air to be evacuated from the bag.

Reverse osmosis membranes treated with polymers bearing carboxylic acid groups and optionally pendant hydroxyl or amide moieties display enhanced salt rejection and/or increased water flux. This treatment is particularly useful for improving the membrane characteristics of cellulose acetate and polyamide membranes.
