Latest Patents

Among his latest inventions, Kaiga developed an “Ultraviolet Irradiation System and Water Quality Monitoring Instrument.” This sophisticated system guides a portion of pre-treated water flowing into an ultraviolet irradiation tank to a fluorometer. The fluorometer scans for an excitation spectrum peak wavelength at a fluorescence wavelength fixed to 425 nm, allowing for continuous measurements of the excitation spectrum. By analyzing the results from the fluorometer, the system can optimize the ultraviolet irradiation level, effectively controlling the irradiation of ultraviolet rays.

Additionally, Kaiga has created a “Water Treatment Control System for Minimizing Trihalomethane Formation.” This system consists of chlorine injection equipment with multiple injectors and a fluorescence analyzer positioned upstream of the chlorine injectors. It calculates the necessary chlorine injection rate to reduce trihalomethane formation potential based on measurements from the fluorescence analyzer. The control apparatuses then adjust the chlorine injection amount according to the calculated rates and readings from a water flowmeter.
