“…A latest research identified the macrophyte, Typha angustifolia as a possible hyper-accumulator for the elimination of Co, Cu as well as Pb from an FWS-CW using a controlled method to phytoremediation [ 193 ]. Meanwhile, the effectiveness of several other CW plants has currently been recorded, such as Zantedeschia aethiopica, Cyperus alternifolius, Heliconia burleana, Canna indica, Acorus calamus, and Ipomoea aquatic [ 194 , 195 ], including a waterlogged plant, Elodea densa, that has already demonstrated considerable capability in pollutant purification [ 196 ].…”

Constructed wetlands (CWs) are affordable and reliable green technologies for the treatment of various types of wastewater. Compared to conventional treatment systems, CWs offer an environmentally friendly approach, are low cost, have fewer operational and maintenance requirements, and have a high potential for being applied in developing countries, particularly in small rural communities. However, the sustainable management and successful application of these systems remain a challenge. Therefore, after briefly providing basic information on wetlands and summarizing the classification and use of current CWs, this study aims to provide and inspire sustainable solutions for the performance and application of CWs by giving a comprehensive review of CWs’ application and the recent development of their sustainable design, operation, and optimization for wastewater treatment. To accomplish this objective, thee design and management parameters of CWs, including macrophyte species, media types, water level, hydraulic retention time (HRT), and hydraulic loading rate (HLR), are discussed. Besides these, future research on improving the stability and sustainability of CWs are highlighted. This article provides a tool for researchers and decision-makers for using CWs to treat wastewater in a particular area. This paper presents an aid for informed analysis, decision-making, and communication. The review indicates that major advances in the design, operation, and optimization of CWs have greatly increased contaminant removal efficiencies, and the sustainable application of this treatment system has also been improved.

“…The efficient use of water has been studied (Gervásio et al, 2017) and use of heliconia as alternative for the control of wastewater contamination. In the latter mentioned, heliconias are used in high-speed artificial wetlands that use artificial carriers for bacterial growth as a support medium in a process of phytodepuration against emerging contaminants (Peña-Salamanca et al, 2013;Atalla et al, 2019;Cano et al, 2019;Corzo and Sanabria, 2019;Oliveira et al, 2019;Pérez-Salazar et al, 2019;Sandoval et al, 2019;Cano et al, 2020).…”

Global vision of heliconias research as cut flower: a review

It is relevant to systematize the global knowledge generated about heliconia due to its economic importance in tropical floriculture and the cut flower market. The objective was to explore the results generated in scientific research related to the cultivation of heliconias as cut flower in terms of its methodological approach, research axes, and spatial distribution in terms of the contributions by country. A bibliographic search was conducted in Scopus, Web of science and SciELO based on the keywords “heliconia” and “tropical flowers”. Thereafter, a content analysis of the documents was conducted with the Nvivo software using a priori categories in terms of methodological approach, research axes, year, countries, and cultivars or varieties. The results indicate that the scientific contributions are mostly under a quantitative approach (98.1%). The investigations mainly address productive aspects (74.5%), post-harvest aspects (16.1%), market (6.7%) while industry-used products (2.5%) are scarcely addressed. The countries that make the most contributions are: Brazil (54.5%), Colombia (15.4%) and Mexico (10.9%). The most important species are: H. psittacorum, H. bihai, H. spathocircinata, H. rostrata and H. wagneriana. These results suggest conducting research to identify problems from the physiological, environmental, productive, and economic processes, as well as considering the strategies of farmers as a priority. This must be approached from paradigms where social actors (farmers), their development and the impacts of their social tasks on the cultivation of heliconias are considered the main axis.

“…These substrates are available in different shapes and sizes and offer various colonies for the biofilms due to their characteristics of providing an additional specific surface area and intensive hydrophilicity. Biofilm carriers enhanced the microorganism attachment (Corzo and Sanabria, 2019) and consequently improved the treatment efficiency by increasing nutrient assimilation and oxygen transfer (Al-Amshawee et al, 2020).…”

“…In this regard, some studies have examined the impact of diverse biofilm carriers coupled with floating bed wetlands (Li et al 2010; Cao and Zhang 2014; Zhang et al 2016), subsurface flow wetlands (Corzo and Sanabria, 2019;Shiwei et al, 2019;Zamora et al, 2019), and hybrid systems (Chyan et al, 2013). However, no research has yet examined the performance of free water surface wetland planted with free-floating plants integrated with biofilm carriers prepared from waste plastic materials as a support media.…”

Increasing the demand for potable water, followed by the high quantity of discharged effluents linked with the water scarcity problems has necessitated giving more attention to improving wastewater treatment processes and operations. The constructed wetland has proven to be an excellent green sustainable technique for purification. This study aimed to examine the performance of four experimental free water surface constructed wetlands (FWSCWs) for the depuration of sewage effluents as a secondary treatment stage during winter season conditions. The objectives were to assess the raw and treated wastewater concentrations, evaluate the removal efficiency of chemical oxygen demand (COD), biological oxygen demand (BOD), nutrients, and total suspended solids (TSS) of each treatment line, and compare the impact of plastic rings (biofilm carriers) and Lemna minor L. with the presence of gravel bed on the treatment efficiency and bacterial growth, as well as assess the plant's adaption and growth. The results showed that all treatment systems improved the water characteristics, and adding biofilm carriers enhanced the efficiency of water purification, especially BOD reduction. The combination of the plants, biofilm carriers, and gravel in the wetland filter significantly enhanced (ρ < 0.05) the treatment efficiency in terms of TSS, COD, BOD, Ammonia (NH 3 ), Nitrates (NO 3 ), and Orthophosphate (PO 4 ) compared to the control treatment system (gravel bed). Plant growth was restricted in the presence of carriers in the system. Further study for examining the system performance under summer conditions, which may improve the nutrient reduction rates by biofilm carriers, is underway.
