Abstract

Due to recurring expenses like operation costs, which frequently do not justify the investment costs, the economic viability of conventional treatment facilities in areas with large seasonal population turnover or low populations is a big challenge. To successfully decrease the release of toxins into river basins, it has become crucial to consider alternate treatment methods for home and industrial wastewater. 23 active medicinal compounds were examined, and 8 were found in 6 nature-based treatment facilities and 3 in conventional wastewater treatment facilities. It was vital to find out whether the nature-based removal technologies would have comparable removal efficiency to the traditional treatment works while examining the removal efficiencies of the discovered contaminants across the nine locations. This work employed passive Diffusive Gradients in Thin Films (DGT) samplers using XAD Amberlite 18 as the binding gel. Clarithromycin effluent concentrations were higher than influent concentrations at all three conventional treatment facilities, suggesting that CLM may have entered the treatment system in a conjugate form rather than the compounds we looked at. Sui et al. (2015) identified CLM as one of the PPCPs with negative removals in the secondary treatment facility
