PROBLEM TO BE SOLVED: To provide a culturing solution cleaning apparatus in which the frequency of exchange of a filter membrane for the culture solution cleaning apparatus for cleaning a culturing solution for nutrition solution culturing by means of membrane filtration is remarkably decreased, and which can be stably operated for a long time. SOLUTION: The culture solution cleaning apparatus for cleaning the culturing solution for nutrition solution culturing by means of membrane filtration, is characterized by having a differential pressure detecting means, a flow rate detecting means, an air scrubbing treating means, a hypochlorite treating means, an air scrubbing treating judging means for making the air scrubbing treating means perform air scrubbing treating when the differential pressure between the upstream and the downstream of the filter membrane becomes to a specified pressure or higher and the filtration flow rate is at least a specified flow rate and a hypochlorite treating judging means for making the hypochlorite treating means perform a hypochlorite treating when the differential pressure between the upstream and the downstream of the filter membrane becomes to a specified pressure or higher and the filtration flow rate is lower than a specified flow rate. |
