This study evaluates the role of design, operational, and physicochemical parameters of constructed wetlands (CWs) in the removal of pharmaceuticals (PhCs). The correlation analysis demonstrates that the performance of CWs is governed by several design and operational factors (area, depth, hydraulic loading rate, organic loading rate, and hydraulic retention time), and physicochemical parameters (dissolved oxygen, temperature, and pH); the removal efficiency of about 50% of the examined PhCs showed a significant correlation with two or more factors. Plants contributed significantly in the removal of some of the PhCs by direct uptake and by enhancing the process of aerobic biodegradation. The use of substrate material of high adsorption capacity, rich in organic matter, and with high surface area enhanced the removal of PhCs by adsorption/sorption processes, which are the major removal mechanisms of some PhCs (codeine, clarithromycin, erythromycin, ofloxacin, oxytetracycline, carbamazepine, and atenolol) in CWs. Although the removal of almost all of the studied PhCs showed seasonal differences, statistical significance was established in the removal of naproxen, salicylic acid, caffeine, and sulfadiazine. The effective PhCs removal requires the integrated design of CWs ensuring the occurrence of biodegradation along with other processes, as well as enabling optimal values of design and operational factors, and physicochemical parameters.

“…PPCPs are widespread in prescriptions, over-the-counter drugs, spices, cosmetics and daily care products [3,4], but most conventional wastewater treatment processes are not designed for removing these micro-organic pollutants. Some chemicals, including hormone, antimicrobial agents, moschus, and fire retarding agents, have been detected in nearly every water environment [5]. Most PPCPs are hydrosoluble and some show polar properties related to acid or alkaline bases.…”

“…Except for DEET (p<0.05), no significant difference was observed between removals with (DO above 7.98 mg/L in CW tank) and without aeration (DO at 5.32~6.26 mg/L in CW tank) (p>0.05) for the other three compounds. DEET is usually regarded as a recalcitrant compound [47,48]. Higher DO concentration in the CW significantly favoured DEET elimination and removal of aerators led to higher concentration of DEET in effluents [29].…”

A serially connected lab-scale Greater duckweed constructed wetland (CW)stabilization tank (ST)-GAC sandwich slow sand filtration system was tested to remove four widely detected pharmaceuticals and personal care products (PPCPs) compounds from natural water with a spiked concentration of 25 μg/L. High removals were achieved rapidly (93.5~100%), being on average 95.9%, 99.1%, 98.1% and 97.4% for DEET, paracetamol, caffeine and triclosan (n=3), respectively. Except for DEET, no significant difference was observed between overall removals with and without artificial aeration in CW tank (p>0.05), showing good stability of the system. COD was considerably removed under aeration and final TOC removal was 64.7%. No nitrite, nitrate, ammonia and phosphate were detected at the test end (day 26). The microbial community structure in three connected units of the tested system showed differences and good stability after the aerators were removed. Proteobacteria was the most dominant phylum among the 47 phyla found. Microbes attaching to the Greater duckweed contributed more to the microbial community structure in CW and ST than *Revised Manuscript (clean for typesetting) Click here to view linked References original natural water. However, at the end of the run, the structural differences among three units decreased. After aeration stopped, phylum composition became more stable in ST tank while CW tank showed small structural variation throughout the test. Various correlations were found between detected phyla, among which Proteobacteria and Bacteroidetes showed a significant negative correlation (R=-0.73, p<0.001, FDR corrected). Good removal of target PPCPs and stability of the system show the potential applicability of this combined treatment process.
