Akin type (asymmetric) reverse osmosis membranes undergo an irreversible osmotic dehydration upon coming into contact (skin side) with salt solutions. The extent of consequent changes (in appearance; decrease in linear dimension. water flux and salt rejection) are dependent on the salt concentration. These observations are correlated with the expected morphological changes taking plac... https://danddcollectiblers.shop/product-category/dog-charms/
