On treatment of water quality stability of superhard and super-alkali circular water of air-conditioner

According to the water of air-conditioner water with serious scaling of Jiangnan Group of Wuhan,the paper adopts the experiment of the water quality stability by adopting the scale inhibitor,proves by the experiment results that the scaling problem can be solved when the density of the added scaling inhibitor sodium hexametaphosphate reaches 1.39 mg/L and the carbonate hardness in water can be stabilized around 570 mg/L(CaCO3).
