都市下水再生の現状と課題を水質・エネルギー・資源回収・GHG削減の観点から整理したレビュー。膜バイオリアクターや藻類細菌膜、栄養塩保持型処理など新興プロセスを評価し、用途別の処理強度と導入規模の統合が重要と指摘。RO系・非RO系の選択と集中・分散・ハイブリッド構成を地域条件に合わせることで、低炭素で資源循環型の都市水システムへの移行を展望する。
English
A review of municipal wastewater reclamation assessing water quality, energy, resource recovery and GHG mitigation. It evaluates emerging configurations—membrane bioreactors with RO, algal–bacterial membranes, nutrient-retaining and non-RO advanced treatment—showing applicability varies by reuse purpose. The authors argue technology selection should integrate treatment intensity with deployment scale, and that system-level evaluation of energy, emissions, economics and residual streams is essential for low-carbon, circular urban water systems.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
下水処理場の省エネ・創エネは国内でも脱炭素計画の柱であり、水処理インフラのGHG削減や資源回収に関心を持つ自治体・事業者にとって参考になる。ただしSSBJや有報開示への直接的な示唆は乏しい。
In the global GX context
Water utilities are increasingly in scope for climate disclosure and net-zero targets, and this review's system-level framing of energy, GHG and resource recovery connects to global water-sector decarbonization and circularity agendas, though it does not engage TCFD/ISSB disclosure frameworks directly.

📄 Abstract（原文）
Municipal wastewater reclamation is becoming increasingly important for alleviating water scarcity, reducing dependence on freshwater resources and improving the sustainability of urban water systems. This review examines the current status and major challenges of municipal wastewater reclamation and discusses its future development from the perspectives of water quality, energy use, resource recovery and greenhouse-gas mitigation. Future reclamation systems are expected to place greater emphasis on end-use-oriented treatment, energy efficiency, resource retention and carbon-conscious process design. Several emerging process configurations are evaluated, including aerobic and anaerobic membrane bioreactor systems coupled with reverse osmosis, algal–bacterial membrane processes, nutrient-retaining treatment for agricultural reuse and non-RO advanced treatment based on oxidation and biological filtration. Their applicability varies with the intended reuse because of differences in water quality control, energy demand, resource recovery and residual-stream generation. Future technology selection should therefore integrate treatment intensity with deployment scale. RO-based and non-RO-based pathways can be selected according to the dominant water quality constraints, while centralized, decentralized and hybrid systems should be matched to local infrastructure, reuse distance, water demand and resource recovery opportunities. The system-level evaluation of water quality, energy consumption, greenhouse-gas emissions, economic performance and residual-stream management will be essential for guiding future deployment. Municipal wastewater reclamation is expected to evolve toward adaptable, fit-for-purpose treatment portfolios that support water sustainability, resource circularity and the transition toward low-carbon urban water systems.
