Influence of Processing Variables on the Transport Properties of Celluose Acetate Membranes. Ultimatpresent membrane formulations [1], and the other, the development of tubular membranes [1,2]. The tubular approach shows a strong potential for commercialization, mainly because the tubular geometry offers large surface area per unit volume. The surface area available for desalination can be further

The Preparation and Properties of Styrene Grafted Cellulose Acetate Membranes for Desalinationsures used for seawater desalination lead to the gradual compaction of the expanded Loeb-Sourirajan type membrane structures with a consequent decrease of the product flux rate and apparent salt rejection. It seemed of interest, therefore, to study modifications of cellulose acetate which would redu

The Phenomenological Characterization of DP-1 Membranesntil recently cellulose acetate membranes were the only practical desalinating membranes developed; however, with the discovery of permselective, aromatic, nitrogen-containing polymeric membranes by Richter and Hoehn[1], a whole new class of practical reverse osmotic membranes is available. These ne

Generalized criteria necessary for optimum reverse osmosis performance in terms of chemical structure of the macromolecule may not be evident. On the other hand, some physicochemical properties such as the equilibrium water content of the membrane may play a more importan
