Summary: A full-scale Vertical Flow Constructed Wetland (VFCW) project was implemented in Oman to provide a sustainable wastewater treatment solution. The study showed high removal rates for pollutants, but nitrogen removal still faced challenges, prompting the testing of various operational modifications to optimize treatment performance.

Summary: A hybrid constructed wetland system combining horizontal and vertical flow was used to treat carbon-deficient synthetic dyeing wastewater. The results showed that the system could effectively remove azo dyes from low-carbon dyeing wastewater. In the horizontal wetland, organic waste products served as the carbon source for microbial dye degradation, resulting in 90% color removal. The vertical wetland removed dye degradation organics, ammonium-nitrogen, and organic-nitrogen.

Summary: Emerging organic micropollutants, especially pharmaceutical residues, pose a threat to aquatic environments. Natural wastewater treatment systems can partially remove pharmaceuticals, but effluent recirculation can significantly improve removal, especially in water-scarce regions.

Summary: This study successfully demonstrated the application of a lab-scale baffled horizontal constructed wetland with mixed organic media for zinc removal from high acidity sulfate-rich wastewater. The wetland showed high efficiency with 95% zinc removal, mainly retained within the wetland media. Microbial community analysis revealed the dominant phyla present in the wetland.

Summary: The study on four pilot-scale Vertical Flow Constructed Wetlands (VFCWs) with Phragmites australis planted in gravel showed promising efficiency in arsenic removal from contaminated wastewater at different concentrations. The result also indicated the effectiveness of substrate accumulation in arsenic removal and the adaptability for treating arsenic-containing wastewater.

Summary: The study found that the zigzag-horizontal subsurface flow constructed wetland using Echinodorus cordifolius plants could efficiently remove algal cells, PO43-, and NO3- within 5 days. This was achieved through the interception mechanism of gravel and zigzag baffles, as well as the enhanced dissolved oxygen levels and increased interaction time between wastewater and the CW matrix created by the installation of zigzag baffles and effluent recirculation.

Summary: This study investigated the retention of microplastics and their impact on the efficiency of constructed wetland treatment. The results showed that microplastics had no significant effect on the removal of COD, BOD5, DOC, and N-NH4+, while there was a significant decrease in N-NO2- concentration and an increase in P-PO43- concentration in the effluent after the addition of microplastics. Microplastics were efficiently retained in the wetland, with only a small amount detected in the effluent. Therefore, constructed wetlands are effective in preventing the release of microplastics into the aquatic environment, but the high retention of microplastics may alter nutrient cycling in wetlands.

Summary: The present study investigated the application of a multilayer quartz sand substrate horizontal subsurface flow constructed wetland (HSFCW) for campus sewage treatment. The results showed that under a high organic loading rate, the multilayer HSFCW had a higher COD removal rate compared to the mololayer HSFCW, indicating better adsorption and biodegradation ability of organic matter. The multilayer HSFCW also demonstrated impressive clogging resistance capacity due to the lower contents of insoluble organic matter, which helped prevent membrane fouling. Certain bacteria species further enhanced the anti-clogging performance by contributing to the degradation of organic matter. Based on these findings, the application of the multilayer HSFCW operated under high hydraulic loading rate and low COD concentrations was recommended for long-term domestic sewage treatment.

Summary: The study showed that vertical flow constructed wetlands using natural pyrite as substrate can enhance nitrate removal efficiency and promote heterotrophic denitrification to avoid nitrite accumulation. Additionally, the growth of plants in wetlands, particularly Canna indica, was better in wetlands using pyrite as substrate. High-throughput sequencing revealed differences in denitrifying bacteria, iron oxidation and reduction microorganisms, and rhizosphere microorganisms in the wetlands.

Summary: This study investigated the removal of nitrogen and sulfamethoxazole (SMX), and the microbial communities in a partially saturated vertical flow constructed wetland (PS-VFCW) fed with synthetic mariculture wastewater operated at different saturated zone depths (SZDs). The results showed that SZD had a significant impact on the removal efficiency, with different depths showing variation in nitrification and denitrification performance. Various important microbial communities were found in the unsaturated zone, which played a key role in the removal of organics, nitrogen, and SMX.

Summary: This study explored the effects of biomass dosage on the treatment performance, N2O emission, and microbial metabolites in constructed wetlands. The results showed that the addition of biomass significantly enhanced the denitrification performance, with a slight increase in N2O emission. Additionally, the biomass addition increased the accumulation of EPS.

Summary: The study demonstrated the effectiveness of using a pilot-scale vertical subsurface flow constructed wetland planted with Scirpus grossus in removing pharmaceutical compounds from domestic wastewater. Results showed that the wetland system with aeration successfully removed ibuprofen, COD, and nutrients, meeting the effluent standards set by the Malaysian Government.

Summary: The study found that long-term exposure to SMX significantly increased nitrate removal rates in IVCWs, while ammonia nitrogen removal rates were not significantly affected. The presence of SMX led to a decrease in bacterial richness and alterations in bacterial community structures, especially those of nitrogen-transforming microorganisms. The molecular ecological network analysis revealed that SMX had positive effects on denitrifying bacteria interactions but reduced the complexity of the microbial network as a whole.

Summary: Waste stabilization ponds and constructed wetlands are an effective method for removing pharmaceutical residues, but their efficiency is not always complete. This study evaluated the presence of pharmaceuticals in wastewater, their removal in a macrophyte pond-CW system, and the impact of effluent recirculation on removal and ecological risk.
