Polyhexamethylene biguanide and surfactant composition and method for preventing waterline residue

摘要

A water treatment method for controlling the growth of algae, fungi and bacteria and the formation of a waterline residue in recreational and industrial water supplies containing turbulent water utilizes a composition containing a polyhexamethylene biguanide compound and a surfactant. The water treatment method and composition containing the biguanide compound and surfactant are particularly useful for treating recreational water supplies like spas and swimming pools containing turbulent water, such as aerated water.
