PROBLEM TO BE SOLVED: To effectively utilize a RO membrane permeated water being treated water as supply water without performing pH adjustment with an alkali agent in a method for treating a circulating cooling water in which acid is added to a cooling circulating water and the cooling ...
Let a be the original number of ounces of acid and w be the original number of ounces of water. We can write two equations since we know the percentage of acid after the some water and acid \frac{a}{a+w+1}=\frac{1}{5}, \frac{a+1}{a+w+2}=\frac{1}{3}. Cross-multiply ...
