Phosphorus and Nitrogen Recovery from Wastewater and Sediments
This community focuses on removing excess phosphorus and nitrogen from wastewater, sewage sludge, and aquatic sediments, primarily to prevent eutrophication and recover these nutrients for agricultural or industrial reuse.
The work centers on adsorption technologies using biochar, layered double hydroxides, and modified zeolites, alongside biological methods involving microalgae such as Chlorella vulgaris and silver carp. Key processes include struvite crystallization for phosphorus recovery and ammonia stripping for nitrogen. The research also examines the mechanisms of nutrient release from lake sediments and the treatment of municipal wastewater to improve water quality. Specific applications include the production of slow-release fertilizers from treated sludge ash and the use of functionalized materials to capture phosphate from aqueous solutions.
The largest share of the community's output is found in phosphorus research, accounting for 3.7% of all phosphorus research, and 12,434 papers here. Nitrogen research contributes 1.0% of its total research volume, with 5,444 papers in this group.
The community comprises 20,982 papers, publishing most frequently in Water Research, Journal of Water Process Engineering, and Bioresource Technology. Recent work continues to refine adsorption mechanisms using machine learning optimization and explores the seasonal dynamics of nutrient concentrations in riverine systems.
