Especialy the waters which contain large amount of Ca. and Mg. bicarbonate and sulfate salts under different conditions. To soften the hardnessof Ankara city water we decide to use lime-soda ash method which like other countries is more practical and economic for Turkey and succeded to reduce the hardness to the 14 even 10 French hardness degree which was originally 58.</p></trans-abstract>
