Latest Patents

One of Masayuki Miwa's latest inventions is a pure water producing apparatus. This apparatus prevents fluctuations in the amount of produced pure water without requiring a heat exchanger. The process involves filtering raw water with an activated carbon filtration device, which is then sent through a water supply pump to a reverse osmosis device for demineralization. The demineralized water output from the reverse osmosis device contacts a water quality sensor, including a water temperature sensor, before being sent to an electrodeionization device. This device subjects the water to electrodeionization, ensuring high-quality treated water output.

Another notable patent is the electrodeionization apparatus. This apparatus comprises multiple anion exchange membranes and cation exchange membranes that are alternately arranged between a cathode and an anode. This arrangement forms concentrating compartments and desalting compartments, which are filled with ion exchangers. The filling ratio of the anion exchanger to the cation exchanger in the concentrating compartments is higher than that in the desalting compartments, enhancing the efficiency of the desalination process.
