“…Moreover, Xu and Shen (2011) found that at initial TPO 4 concentration of 30.6 mg/l, removal efficiency by duckweed from wastewater was 24%. Also, Sudiarto et al, (2019) found that Limna sp had the highest phosphorus removal of 36.15%. Alvarado et al (2008) and Gao et al, (2009) reported that the plants removal capacity increased with the increment in nitrogen and phosphorus in water.…”

Keywords: Oreochromis niloticusPhytoremediation Ceratophyllum demersum Lemna minorAquaculture Wastewater Pollution Two aquatic macrophytes, Ceratophyllum demersum and Lemna minor, were used in aquaculture wastewater treatment. Tilapia fish (Oreochromis niloticus) with total body weight of 50-60 g were placed in 60 L aquaria. Four treatment groups were included: control (no plant treatment, depended on artificial filtering for purification), Lemna minor (Lm), Ceratophyllum demersum (Cd), and mixed plants group (Lm+Cd). Each group had three replicates (5 fish/replicate). The experiment was conducted for 4 weeks. Physicochemical parameters of aquaculture wastewater including pH, total dissolved solids (TDS), conductivity, turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total phosphorous (TPO 4 ), nitrate (NO 3 ), nitrite (NO 2 ), and ammonia were determined. The results reflected more effective removal of pollutants from fish aquaria by both plants than that by the artificial aeration/filtering. The effectiveness of pollution removal was higher in Cd group > Lm > Lm+Cd, compared to the control. This order of phytoremediation was confirmed by improvements in tilapia fish health status including liver function (AST, ALT, albumin), kidney function (creatinine, urea, uric acid), in addition to other nutritional and hematological parameters. It could be concluded that the phytoremediation using C. demersum is ecofriendly and effective in removing contaminants from Tilapia aquaculture wastewater and therefore, it is recommended to be applied in tilapia farms.

“…They are easier to maintain and harvest after the treatment (Tel-Or and Forni, 2011). In addition, the harvested biomass can be utilized for many purposes such as animal feeding or feedstock for renewable energy production (Muradov et al, 2014;and Sudiarto et al, 2019).…”

“…For instance, Lu et al [11] reported the great potential of P. stratiotes to remove N and P from various types of polluted water. Moreover, total N (TN, 63.2%) and total P (TP, 36.2%) were removed by remediating treated swine wastewater with Pistia stratiotes and Lemna sp., respectively [19]. Iamchaturapatr et al [20] tested 21 plant species and suggested that the N and P removal capacity depended on the species.…”

Phytoremediation is a potentially suitable technology for taking up large amounts of N and P during plant growth and the removal of plant material, thereby avoiding eutrophication. We compared the capacity of nine different aquatic plant species for removing total P (TP), total N (TN), and NH4+-N from raw domestic sewage wastewater collected from a living area located in Guangzhou city, China, and different concentrations of artificial wastewater. The experiments were performed in two stages, namely screening and modification. In the screening stage, four plant species were identified from the nine grown in raw domestic sewage water for 36 days. In the modification stage, the TN and TP removal ability of different plant combinations were determined in artificial wastewater at different N/P concentrations. After having been grown in monocultures for 46 days, Ipomoea aquatica (90.6% and 8.8%) and Salvinia natans (67.3% and 14.2%) obtained the highest TP removal efficiency in lightly and highly polluted wastewater, respectively. The combination of S. natans and Eleocharis plantagineiformis effectively removed TP and TN from lightly polluted water, suggesting that this combination is suitable for phytoremediation of eutrophic wastewater.

“…It is widely known that aquatic plants in water bodies such as rivers and reservoirs can improve water quality [1][2][3]. In particular, floating plants live on the water surface rather than rooting in soil; as their leaves and stems float on the water surface, floating plants block light penetration, hinder the photosynthesis of phytoplankton, and reduce the concentration of chlorophyll-a, thereby suppressing green algae [4].…”

In this study, aquatic plants in a small reservoir were detected using multispectral UAV (Unmanned Aerial Vehicle) imagery and various vegetation indices. A Firefly UAV, which has both fixed-wing and rotary-wing flight modes, was flown over the study site four times. A RedEdge camera was mounted on the UAV to acquire multispectral images. These images were used to analyze the NDVI (Normalized Difference Vegetation Index), ENDVI (Enhance Normalized Difference Vegetation Index), NDREI (Normalized Difference RedEdge Index), NGRDI (Normalized Green-Red Difference Index), and GNDVI (Green Normalized Difference Vegetation Index). As for multispectral characteristics, waterside plants showed the highest reflectance in Rnir, while floating plants had a higher reflectance in Rre. During the hottest season (on 25 June), the vegetation indices were the highest, and the habitat expanded near the edge of the reservoir. Among the vegetation indices, NDVI was the highest and NGRDI was the lowest. In particular, NGRDI had a higher value on the water surface and was not useful for detecting aquatic plants. NDVI and GNDVI, which showed the clearest difference between aquatic plants and water surface, were determined to be the most effective vegetation indices for detecting aquatic plants. Accordingly, the vegetation indices using multispectral UAV imagery turned out to be effective for detecting aquatic plants. A further study will be accompanied by a field survey in order to acquire and analyze more accurate imagery information.
