脱塩とは、海水や汽水地下水から溶解した塩分やミネラルを除去して、飲料水や灌漑用水として利用できる淡水を生成する産業および工学分野であり、現在では中東、北アフリカ、アジア沿岸部、そして近年では南ヨーロッパやアメリカ大陸など、水不足に悩む地域で1億人以上の人々に水を供給している。
逆行する 浸透 逆浸透(RO)は現在の設備容量の大部分を占め、高濃度の塩水供給を担っている。 プレッシャー 薄膜複合ポリアミド膜の選択性、汚染耐性、およびホウ素除去率が依然として活発な材料科学研究の最前線である一方、熱プロセス(多段フラッシュ蒸留および多重効果蒸留)は、発電からの廃熱が無料のエネルギー入力として利用できる場合に依然として重要である。この分野における中心的な工学的制約は比エネルギー消費量であり、圧力交換器ベースのエネルギー回収を備えた最先端のROプラントは現在、 熱力学 海水淡水化の最低基準は、膜の寿命、取水設計、濃縮塩水管理、排出毒性、海洋環境への競争的差別化へとシフトしている。 生態系 影響は規制当局の監視強化を招く。
