Paragraph starter

Research by Zhang (2015) highlights that the efficiency of ammonium recovery during urine hydrolysis is significantly influenced by the ratio of stale to fresh urine, the presence of fecal contamination, and the application of specific pretreatments. This suggests that for effective nutrient recovery in wastewater treatment systems, careful control over input stream composition and the integration of tailored pretreatment stages are essential design considerations.
