Desalination
海水淡水化技術は、世界的な水不足に対処するために、海水を淡水に変換する技術である。

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。

Reverse osmosis (RO) dominates current installed capacity, pushing saline feedwater at high pressure across thin-film composite polyamide membranes whose selectivity, fouling resistance, and boron rejection rates remain active material science research fronts; thermal processes — multi-stage flash distillation and multi-effect distillation — retain relevance where waste heat from power generation is available as a cost-free energy input. The field’s central engineering constraint is specific energy consumption: state-of-the-art RO plants with pressure exchanger-based energy recovery now approach the 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。

Emerging process architectures — forward 浸透, membrane distillation, capacitive deionization, and graphene oxide or aquaporin-based membranes — target niche feedwater chemistries or off-grid renewable-powered configurations where conventional RO economics break down.
