Abstract

The emphasis on phosphorus removal and recovery from wastewater treatment plants has intensified in recent years due to the urgent need to reduce dependency on nonrenewable phosphorus reserves. Enhanced biological phosphorus removal (EBPR), driven by a diverse community of polyphosphate-accumulating organisms with distinct metabolic capabilities, offers several advantages over chemical precipitation methods. These benefits include reduced chemical use, lower sludge volumes, decreased reliance on costly chemical precipitants, and improved phosphorus recovery quality. Recent advancements in recovery technologies now enable efficient phosphorus extraction from digester supernatant, dewatered digested sewage sludge, and sewage sludge ash, each yielding different recovery efficiencies. Despite these advances, a comprehensive assessment of the phosphorus recovery potential from these target streams in conjunction with EBPR remains crucial and has yet to be fully explored.

期刊介绍： Current Opinion in Biotechnology (COBIOT) is renowned for publishing authoritative, comprehensive, and systematic reviews. By offering clear and readable syntheses of current advances in biotechnology, COBIOT assists specialists in staying updated on the latest developments in the field. Expert authors annotate the most noteworthy papers from the vast array of information available today, providing readers with valuable insights and saving them time. As part of the Current Opinion and Research (CO+RE) suite of journals, COBIOT is accompanied by the open-access primary research journal, Current Research in Biotechnology (CRBIOT). Leveraging the editorial excellence, high impact, and global reach of the Current Opinion legacy, CO+RE journals ensure they are widely read resources integral to scientists' workflows. COBIOT is organized into themed sections, each reviewed once a year. These themes cover various areas of biotechnology, including analytical biotechnology, plant biotechnology, food biotechnology, energy biotechnology, environmental biotechnology, systems biology, nanobiotechnology, tissue, cell, and pathway engineering, chemical biotechnology, and pharmaceutical biotechnology.
