TL;DR: In this article, the ability of tropical horizontal subsurface constructed wetlands (HSSF CWs) planted with Typha angustifolia to remove four widely used pharmaceutical compounds (carbamazepine, declofenac, ibuprofen and naproxen) at a relatively short hydraulic residence time of 2-4 days was documented.

TL;DR: Removal of caffeine, ketoprofen and clofibric acid were found to follow first order decay kinetics with decay constants higher in the planted beds than the unplanted beds, implying that their removal is not well related to the compound's hydrophobicity.

TL;DR: Correlation between the distribution coefficient (log D(ow)) and removal efficiencies of pharmaceutical compounds in the CWs showed that pharmaceutical removal efficiency was significantly and inversely correlated with log D(OW) value, but not with log K(ow) value.

TL;DR: The presence of plants significantly enhanced both ammonia oxidation and TP removal in both batch and continuous modes of operation as compared to that for unplanted beds, and the influence of batch versus continuous flow on the removal efficiencies was evaluated.

TL;DR: The rather limited plant uptake of naproxen was not surprising despite the fact that its log K(ow) is close to the optimal range (1.8-3.1) for maximal potential for plant uptake, suggesting that the effects of pK(a) and pH partitioning might be more important than lipophilicity.
