WebJul 11, 2024 · Phosphorus (P) is an abundant element in the lithosphere and is essential for all living organisms (Liu et al. 2016 ). In aquatic systems, however, excessive P input can result in eutrophication, leading to harmful algal blooms that impact fish growth and animal and human health (Ascott et al. 2016; Han et al. 2014 ). WebEffluent wastewater phosphorus concentrations can be divided into two components: 1. Soluble phosphorus: the fraction that is available for biological uptake in an EBPR system. 2. Particulate phosphorus: the fraction that is subject to settling and flocculation.
