The effect of de-gassing on the efficiency of reverse osmosis filtration

Rzechowicz, Miles; Pashley, R.M.


Water permeated porous membranes, under a large hydrostatic pressure differential, are likely to create opportunities for vapour and dissolved gas cavitation, which will restrict water flow through the membrane void spaces. The formation of cavities within the voids may be facilitated by the presence of dissolved gases in water. Removal of these gases might, therefore, reduce or prevent cavitation and thereby increase the flow rate through the porous membranes used to purify water. Reverse...[Show more]
