Outline of Final Research Achievements

It was found that the combination of oil solids and floridil generated by calcium ions and oleic acid forms deposits in the drainage pipes. Using an infrared analyzer (NIRFlex N-500, Buchi), a calibration curve for the measurement of oil concentration by near-infrared analysis was prepared, demonstrating the feasibility of using a near-infrared analyzer to measure oleic acid concentration. Oleic acid was measured in a simulated drainage pipe using a near-infrared camera with a bandpass filter (940 nm) and a 940 nm light source. The presence or absence of oleic acid was clearly discernible from the monochrome image, indicating the possibility of real-time measurement of fatty acid concentration in wastewater.
