Abstract

Investigated are working characteristics of reverse-osmotic membranes of low pressure ESPA-1 and TFC-75 in purifying aqueous solutions of phosphates in the range of their concentrations 10–490 mg/dm³. It is shown that at minor difference of selectivity of studied membranes with respect to phosphate–ions the specific capacity of the membrane ESPA-1noticeably exceeds such of the membrane TFC-75.
