Abstract
AbstractPharmaceutically active compounds (PhACs) reaching surface waters through municipal wastewater are a concern, as existing treatment processes poorly remove them. While significant lab-scale...
Highlights
Concern over potential health and environmental impacts of pharmaceutically active compounds (PhACs) and personal care products in surface waters has garnered significant attention in recent years (McBean 2019)
While considerable data on the effectiveness of various treatment processes, especially advanced oxidation processes(AOPs), for the removal of PhACs can be found in the literature, almost all studies were conducted at lab or bench scale and very few reports exist that consider scaling of processes to address full-scale process effectiveness (Almomani et al 2016; Figueredo et al 2019; Hollman et al 2018; Mojiri et al 2019; Somathilake et al 2018)
While the occurrence of PhACs has been investigated around the world, this paper addresses a need for application-scale data, as the study it describes was conducted at a new large-scale test facility embedded in a functioning municipal wastewater treatment plant (WWTP)
Summary
Concern over potential health and environmental impacts of pharmaceutically active compounds (PhACs) and personal care products in surface waters has garnered significant attention in recent years (McBean 2019). While considerable data on the effectiveness of various treatment processes, especially advanced oxidation processes(AOPs), for the removal of PhACs can be found in the literature, almost all studies were conducted at lab or bench scale and very few reports exist that consider scaling of processes to address full-scale process effectiveness (Almomani et al 2016; Figueredo et al 2019; Hollman et al 2018; Mojiri et al 2019; Somathilake et al 2018). The complex matrix of treated municipal wastewater combined with very low PhAC concentrations and scaling issues make lab-scale data of low interest to designers and engineers who make decisions on process design in new municipal facilities. While the occurrence of PhACs has been investigated around the world, this paper addresses a need for application-scale data, as the study it describes was conducted at a new large-scale test facility embedded in a functioning municipal wastewater treatment plant (WWTP). Processes were tested at large scale as if part of a functioning treatment train, allowing the data presented in the paper to be a good representation prior to full implementation
