Abstract
Optimization of Acetaminophen and Methylparaben Removal within Subsurface Batch Constructed Wetland Systems
Highlights
Emerging organic contaminants (EOCs) including pharmaceuticals and personal care products (PPCPs) and pesticides have attracted the most attention, after conventional pollutants were the most threatening to the aquatic environment (Xu et al, 2019)
The objective of this study was to apply Response surface methodology (RSM) accompanied by central composite design to acquire the optimal conditions for the removal of two PPCPs (AC and MP), individually, in subsurface horizontal-flow constructed wetlands using Alternanthera spp
Central composite design (CCD) was performed to model and optimize the removal of AC and MP, individually, by Alternanthera spp from synthetically prepared wastewater
Summary
Emerging organic contaminants (EOCs) including pharmaceuticals and personal care products (PPCPs) and pesticides have attracted the most attention, after conventional pollutants (such as heavy metals and persistent organic pollutants) were the most threatening to the aquatic environment (Xu et al, 2019). PPCPs are widely consumed substances which are frequently detected in surface and ground waters (Hijosa-Valsero et al, 2010). There are several practices that would raise the concentrations of PPCPs in the aquatic environment dramatically. The growing concern about PPCPs results from their recalcitrant behavior in the receiving ecosystems and the unknown consequences of their continual release (Hijosa-Valsero et al, 2010). PPCPs represent a potential threat, as the presence of such substances in the ecosystems may cause antibiotic resistance and endocrine disruptions on humans, livestock and aquatic life (Liu et al, 2019)
