This study investigates the development and efficacy of woodchip bioreactor-bottom ash pellet (WB-BAP) treatment systems for the simultaneous removal of phosphorus and nitrogen from contaminated water sources. Bench-scale experiments demonstrate BAP's potential as a high-performance adsorbent, achieving an outstanding phosphorus removal efficiency of 95% and a maximum adsorption capacity of 58.14 mg/g. Laboratory-scale assessments of the multiple paired system explored various design parameters, including relative configurations, hydraulic retention time (HRT), initial nutrient concentrations, and the nature of nutrient loading. The treatment system configuration significantly affected nutrient removal performance. The WB-BAP setup was the optimal pairing, achieving a nitrate removal efficiency (NRE) of 75.7 ± 4.8% and a phosphorus removal efficiency (PRE) of 62.4 ± 6.4%. Moreover, prolonged hydraulic retention times (HRTs) significantly enhanced nutrient removal, with optimal nitrogen removal at a 24-hour HRT (NRE of 93.0 ± 2.9%). Furthermore, nutrient removal efficiency was influenced by influent concentrations, with higher nitrogen levels improving nitrate removal and lower initial phosphorus concentrations favoring PRE. Continuous flow conditions yielded better nitrogen removal efficiency compared to intermittent flow, although phosphorus removal was not significantly affected by flow type. Overall, this research underscores the potential of BAP and integrated WB-BAP systems as effective solutions for nutrient loss reduction in agricultural runoff and offers insights for further investigation into their long-term effectiveness and scalability for real-world applications."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Synergistic approach for nutrient loss mitigation and waste management using paired modified bottom ash and woodchip bioreactor treatment system"]}]}],"canonical_facts":{"dc:contributor":["Bhattarai, Rabin","Alves de Oliveira, Luciano","Cooke, Richard"],"dc:creator":["Timalsina, Haribansha"],"dc:date":["2024-12-12","2024-12"],"dc:description":["Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-12-01","The student, Haribansha Timalsina, accepted the attached license on 2024-12-06 at 09:55.","The student, Haribansha Timalsina, submitted this Thesis for approval on 2024-12-06 at 10:16.","This Thesis was approved for publication on 2024-12-12 at 10:44.","DSpace SAF Submission Ingestion Package generated from Vireo submission #21529 on 2025-03-28 at 14:56:53","The increasing prevalence of nutrient pollution from agricultural runoff poses significant threats to water quality and ecosystem health.
