Phosphorus Plant Availability of Biochars Derived From Contrasting Sewage Sludges to Ryegrass

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 1027-1035, December 2025.
ABSTRACT Background Although phosphorus (P) is an essential element for human life, it is currently sourced unsustainably primarily from non‐renewable phosphate rock sources. Sewage sludge pyrolysis is a method that concentrates nutrients in sludge, a large renewable P source, to produce a sustainable phosphorus fertilizer.

Genomic and in Situ Analyses Reveal the Micropruina spp. as Abundant Fermentative Glycogen Accumulating Organisms in Enhanced Biological Phosphorus Removal Systems

Frontiers in Microbiology, 2018
Enhanced biological phosphorus removal (EBPR) involves the cycling of biomass through carbon-rich (feast) and carbon-deficient (famine) conditions, promoting the activity of polyphosphate accumulating organisms (PAOs).

Phosphorus Removal by Chemical Precipitation in Wastewater Treatment Plants

Journal of Chemistry, Volume 2025, Issue 1, 2025.
The EU regulations limit the total phosphorus (P) concentration to 2 mg/L in the discharge effluent from wastewater treatment plants to minimize the negative impacts of nutrients in the ecosystems. This study focuses on monitoring and removal of P in the municipal wastewater treatment plant in Baiona, NW Spain.
