Abstract:In circulating cooling water system of scaling, corrosion and microbial propagation are connected: dirt and microbial slime can cause corrosion and corrosion inhibition products formed again, and these problems in dirt high basicity, high hardness and high concentration ratio is more serious run. To solve these problems in the circulating cooling water system, one must be synthetically harness water stability by technology, with the physical and chemical processing the way of combination of control and improve water quality, make the corrosion, circulating cooling water system of scaling, biological dirt effectively solved, thus make water, energy-saving good benefits.
