“…It is important to note that this wetland differs in configuration and plant species from other studies that have reported higher removal rates ranging from 30% to 99% [47]. These results are consistent with what was reported by Mohammed & Ismail [50], who achieved TSS removal efficiencies with Canna indica in a microcosm within a range of 99.2% to 93.4% for a similar type of water. In a laboratory-scale study that employed vertical flow-constructed wetlands to treat dairy wastewater, Canna indica plantations Significant differences (p ≤ 0.001) in average removal efficiencies were observed between the treatments.…”

The aim of this research was to evaluate the efficiency of horizontal subsurface flow-constructed wetlands (HSSFWs) planted with Hippeastrum striatum and Heliconia lastisphata for the treatment of contaminated river waters by wastewater from the dairy industry (WDI) and domestic wastewater in tropical climates over a study period of 136 days. Cell with a real volume of 780,000 mL and a flow rate of 1.805 mL s−1. The hydraulic retention time was determined to be 5 days. 12 individuals of Hippeastrum striatum were planted at a distance of 20 cm from each other in one cell, while in another cell, 12 individuals of Heliconia spp. were planted. An adaptation period was determined for both species. Subsequently, the experiment was started, and the elimination percentages obtained were as follows: COD: 67.94 ± 1.39%, 63.17 ± 2.63%; TSS: 56.49 ± 5.73%, 48.78 ± 5.87%; N-NH4: 51.06 ± 2.16%, 50.80 ± 1.91%; TN: 44.36 ± 5.73%, 30.59 ± 5.87%; TP: 47.00 ± 5.32%, 35.57 ± 4.06%; DO: 50.23 ± 1.61%, 47.74 ± 1.34%; and pH: 6.81 ± 0.07, 6.52 ± 0.1, for Heliconia lastisphata and Hippeastrum striatum, respectively. These results demonstrate that both macrophyte species can be used for the treatment of wastewater from the dairy industry using HSSFWs; cheese factories could be involved in the development of constructed wetland systems to reduce the environmental impact of the industry.

“…Despite having been initially designed to treat domestic wastewater on a small scale, recently, CWs have been used to treat effluents from agriculture and dairy industries, winery, tannery, paper, and pulp, among others. Regarding industrial effluents and their reuse, CWs contribute to a system that can treat water containing high organic loads and different contaminants, while producing a small amount of sludge [28,29]. The efficiency of the removal of the main contaminants of domestic and municipal wastewater in CWs is comparable to that of modern technologies of wastewater treatment, such as the activated sludge process (ASP), sequence batch reactor (SBR), mobile bed biofilm reactor (MBBR), upflow anaerobic sludge blanket (UASB), etc.…”

Constructed wetland systems (CWs) are technologies based on natural processes for pollutant removal and have been more and more accepted in the treatment of domestic and industrial wastewater. This study selected and reviewed articles published in the last six years involving the use of different CW conceptions and their association with other technologies to treat different effluents and evaluated the quality of the effluents for reuse. From a total of 81 articles reviewed, 41 presented quantitative data on the quality of the treated effluent in relation to the requirements of the reuse regulations in different countries of the world. CWs can be used to treat gray water and runoff water, as well as domestic and industrial effluents with the purpose of reusing them. While studies on the removal of new chemical and biological substances have increased, challenges are associated with the optimization of CWs to improve the removal of pathogens and new contaminants that have appeared more recently. The potential for the improved removal of those pollutants lies in the association of CWs with conventional and advanced technologies in new configurations. We concluded that studies related to the reuse of effluents using CWs are in constant evolution, with experiments at different scales. The perspectives are promising since CWs are an economic, environmentally friendly, and efficient technology to help in the mitigation of water scarcity problems imposed by climate changes.

Azorean Vascular Plants with Potential Use in Constructed Wetlands with Horizontal Subsurface Flow

Constructed wetlands are considered integrated ecosystems and a promising wastewater treatment option, relying on vegetation, soils, and microbial assemblages. The potential dispersal of effluents from domestic septic systems, the application of dairy farm effluents containing excessive nutrients and pathogens into pastures, and undertreated effluent discharge in coastal areas are some of the threats to water quality in the Azores. Constructed wetlands could be used in the Azores to protect and preserve the quality of drinking water sources and bathing waters. However, the most used plant species in other regions are considered as introduced in the Azores, where a considerable number of invasive plants and weeds are already present. Here, we present a review of the plant taxa already present in the Azorean flora with the potential to be used in constructed wetland systems, based on a literature review, and on the assessment of nine criteria. We evaluated 73 taxa, including mostly Cyperaceae, Poaceae and Juncaceae, showing that, although some of the top-ranking species were considered potentially noxious, several native and some naturalized taxa could be used for wastewater treatment. This work supports the implementation of constructed wetlands in the Azores, while minimizing the risk of new invasions.
