Description
しかし、大部分の淡水または海水電気分解装置で共通して発生する問題は、特許4〜5で言及したように、電解設備では電極や電気分解槽に電気分解の副産物である水酸化マグネシウム(Mg(OH)2)や水酸化カリウム(Ca(OH)2)が多量に附着し、電解電圧上昇、電極損傷及び電解効率低下などの多くの問題を誘発する。そして過多生産されたバラスト処理水は、排出地域の海洋生物に被害を与える原因として作用するようになる。
更に、船舶のバラスト水を海洋に排出する前に中和装置を通過させることで、過剰に生産された残留塩素の中和効率を高め、装置の小型化及び中和剤の使用を最少にする要件を具備して近隣海洋汚染を防止するように構成されたシステムである。
使用された海水の塩度は2.9%であり、流量は5トン/時間の条件で直流電流を供給しつつ電気分解反応と中和反応を実施した。
Claims (4)
