We have developed the pure water and functional water system for household use that provides pure water by RO and saves water consumption by producing mild alkaline and acidic water with electrolysis of rejected water from RO. Pure water shows excellent abilities in scale inhibition and reducing the amount of detergent in laundry washing. Natural detergent, less than a half of standard amount, has still demonstrates sufficient cleaning ability when it has used with pure water, which suggests the decrease of burdens on the environment. Alkaline and acidic water has shown effective decomposition of alkaline degradable agrichemical and sufficient sterilization abilities, respectively.

Based on field test results, it was confirmed that high performance of consecutive removal of scale origin substances was achieved by water electrolysis using titanium electrodes. 1) This water process technique removes a scale ingredient included in circulating cooling water. 2) The device keeps long-term performance by the change on the polarity of the electrode plate. 3) The system operated for more than 6 months without maintenance and kept its high performance. 4) To evaluate the performance, the amount of removed substances in a unit time was calculated from dissolved evaporation residual substances before and after the electrolysis.
