Abstract
A safe, energy-Saving process for recovering (or purifying) thiocyanate from a large amount of waste liquid (or thiocyanate-containing aqueous solution) by the aid of a reverse osmosis membrane whose sodium chloride rejection is from 10% to 70%. The process performs recovery without decreasing the concentration of thiocyanate in feed.
Claims3
A process for recovering thiocyanate from a thiocyanate-containing aqueous solution, said process comprising filtering the solution through a polymeric reverse osmosis membrane having a sodium chloride rejection rate of 10% to 70%, whereby a filtrate is obtained which contains essentially all of the thiocyanate from said solution.
