“…In the FWs system under study, the characterization results (Table 3) indicate that ADP, AP, GWP, ODP, and HTP are mainly affected by the stage of raw materials production and acquisition. The highest values have been detected in the global warming potential (GWP) and the human toxicity potential (HTP)-a similar effect of the raw materials stage on these two parameters was also reported by Yao et al for combined ecological floating beds [27]. In the categories of FAETP, TETP, and POCP, the construction stage was the most positive contributor, whereas in the case of EP, there was an almost equal contribution of the raw materials stage and the operational stage of the system.…”

The growing environmental awareness of society, the advancement of nature-based solutions (NbSs), and the need for reliable and cost-effective solutions create a favorable environment of opportunities for floating wetlands as alternative solutions for marine water pollution control. The aim of this work was to screen, through OpenLCA, the environmental impacts of floating wetlands for marine water pollution control at various life cycle stages of the system, and assess its economic performance and contribution to the welfare of society. The stage of raw materials production and acquisition was found to be responsible for the main environmental impacts of the floating wetlands, especially on global warming potential, whereas the main impact of the operational stage was related to the eutrophication potential due to N and P residuals in the effluent. The economic performance indicators of economic net present value (ENPV), economic rate of return (ERR), and benefits/costs ratio (B/C ratio) indicate, although marginally, that floating wetlands may constitute a viable investment with potential positive socioeconomic impacts. However, there are still several scientific challenges and technical issues to be considered for the operational application of such systems at full-scale in marine environments.

“…In a study, Wang et al ( 2021 ) reported as Ss = 5–100 mg/L; DO = 2–9 mg/L; BOD 5 = 0–12 mg/L; COD = 30–150 mg/L; TP = 0.1–1.0 mg/L; TN = 2–6 mg/L for a hyper-eutrophic Lake in China. The worst lake water quality in Chinese standards was defined as DO < 1 mg/L, COD = 61 mg/L, NH 3 –N = 4.25 mg/L, TKN = 14 mg/L, and TP = 0.82 mg/L (Yao et al 2021 ). DO, COD, NH 3 -N, TKN, and TP average concentrations of lake water were 7.77, 18.11, 0.31, 1.06, and 0.05 mg/L, respectively.…”

Considering water quality is an essential requirement in terms of environmental planning and management. To protect and manage water resources effectively, it is necessary to develop an analytical decision-support system. In this study, a systematic approach was suggested to evaluate the lake water quality. The methodology includes the prediction of the values in different locations of the lakes from experimental data through inverse distance weighting (IDW) method, creation of maps by using Geographic Information System (GIS) integrated with analytic hierarchy process (AHP) from multi-criteria decision analysis (MCDA), reclassification into five class, combining the time-related spatial data into a single map to predict the whole lake water quality from the data of sampling points, and finally overlapping the final maps with topography/geology and land use. The proposed approach was verified and presented as case study for Meke and Acigol Lakes in Konya/Turkey which were affected by human and natural factors although they have ecological, hydromorphological, and socio-economic importance. In the proposed approach, categorizing water quality parameters as “hardness and minerals,” “substrates and nutrients,” “solids content,” “metals,” and “oil-grease” groups was helpful for AHP with the determined group weights of 0.484, 0.310, 0.029, and 0.046, respectively. Assigning weights within each group and then assigning weights between groups resulted in creating accurate final map. The proposed approach is flexible and applicable to any lake water quality data; even with a limited number of data, the whole lake water quality maps could be created for assessment.

“…Previous reports have also indicated reduced P removal efficacy in plant systems. For example, Yao et al used C. indica that removed 50.9-74.0% of phosphates from SEW (Yao et al 2021). In a similar study, an ecological floating bed composed of Typha domingensis could only remove 37% phosphate from household wastewater (Benvenuti et al 2018).…”

“…One of the impacts of the growing human population on the environment is an increase in the rate at which nitrogen (N) and phosphorus (P) enter the biosphere, which is expected to increase far more in the next few decades (Yao et al 2021). These large amounts of nutrients being discharged into water bodies via domestic, agricultural, and industrial effluents lead to environmental pollution, thereby causing eutrophication (Boeykens et al 2017).…”

Developing solutions for lake eutrophication has emerged as a priority area to address the loss of ecosystem balance, reduction in aquatic biodiversity, and the potential production of toxins. Floating bed solutions offer an effective methodology to address this issue. This study uses rice straw as a base for floating bed treatment. Treatment of simulated eutrophic water was analyzed with and without plants in combination with rice straw beds (RS and RS + P). Treatment efficiency was also tested under increased aeration conditions (RS + A). Results demonstrated that average removal efficiencies of the ecological beds assembled with plant and aerator ranged from 81 to 82%, 80 to 85%, 78 to 86%, 61 to 69% for COD, NH4+-N, NO3−-N, and phosphates, respectively. The microbial community structure was also analyzed from the water samples taken from ecological beds assembled with plant and aerator by 16S rRNA gene sequencing. Based on the above results, systems assembled with plants and aerators proved to be efficient for the treatment of eutrophic water.
