PROBLEM TO BE SOLVED: To secure safety of a patient by cleaning piping which is mainly arranged upstream of a reverse osmosis pure water production apparatus by removing a bio-film in the piping, thereby reducing an ET concentration in clean water (hereinafter called as raw solution) to be supplied to the reverse osmosis pure water production apparatus which is arranged in a dialysis treatment system, and consequently suppressing the concentration of ET contained in a dialyzing fluid which is supplied to the patient, to the minimum, and to reduce the cost of a dialysis treatment by increasing the duration of service (life) of ETF. SOLUTION: A water-containing compressed air supply apparatus for supplying compressed air-including water is connected to one end of the piping which supplies raw water to the reverse osmosis pure water production apparatus in the dialysis treatment system. Then a high-speed air flow containing water is generated in the piping by the water-containing compressed air supply apparatus to remove deposition containing the bio-film in the piping.
