The product is made of imported raw materials and formulations, and the efficiency of the imported products is reached. It can effectively control the scale of inorganic matter, which can effectively prevent the occurrence of scaling in a wide range of concentration. To control the fouling of the membrane separation system, carbonate, sulfate, effective sting of plasma of calcium and magnesium in water, fouling crystal distortion preventing crystal growth. In the play of scale inhibition will not produce soluble in water, the precipitation of the material, the control of aluminum, iron and heavy metal pollutants particularly effective, water quality pH range in 5-9 are effective. Can be added or after dilution and direct, prolonged cleaning cycle, the service life of the membrane, reduce operating costs.
