해수 담수화는 해수 또는 염분이 섞인 지하수에서 용해된 염분과 미네랄을 제거하여 식수 또는 관개용수로 사용할 수 있는 담수를 생산하는 산업 및 공학 분야입니다. 현재 중동, 북아프리카, 아시아 연안 지역, 그리고 점차 남유럽과 아메리카 대륙의 물 부족 지역에서 1억 명이 넘는 사람들에게 담수를 공급하고 있습니다.
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 열역학적 해수 담수화의 최소 요구 사항은 막 수명, 취수 설계 및 염수 농축액 관리 측면에서 경쟁 우위를 확보하는 방향으로 전환되며, 배출수의 독성과 해양 오염 문제가 중요해집니다. 생태계 그 영향으로 인해 규제 당국의 감시가 강화되고 있습니다.
Emerging process architectures — forward 삼투, 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.
