WATER QUALITY ADJUSTMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a contrived water quality adjustment apparatus in which not only silicon dioxide can selectively be removed from rainwater but also metallic corrosion is decreased by reducing a hardness component and adjusting a pH-value and the breeding of algae, bacteria and slime can be suppressed by applying sterilization and removing a suspension material. SOLUTION: An anode plate 1A among electrodes that electrolyzes rainwater WT is composed by using aluminum.
