Abstract

Solution is passed through a crystalliser to grow crystals and form a concentrated sludge of solution and crystals. Preferably the sludge is filtered and a concentrated solution and a sludge of higher crystal content by wt. is obtained. The sludge is centrifuged to separate the ice crystals and extract a concentrated solution.
