The lack of clean water sources, due to the presence of pollutants in water, is a major issue in many countries, including Malaysia. To overcome this problem, various methods have been introduced, including phytoremediation treatment. Therefore, this phytoremediation study examined the ability of five aquatic plants—Centella asiatica, Ipomoea aquatica, Salvinia molesta, Eichhornia crassipes, and Pistia stratiotes—to remove three pollutants—total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and phosphate—from aquaculture wastewater. Using wastewater samples, each containing 50 g of one of the plants, the pollutant levels were measured every two days for 14 days. The results showed a drastic decline in the concentration of pollutants, where C. asiatica was able to remove 98% of NH3-N, 90% of TSS, and 64% of phosphate, while I. aquatica showed the potential to eliminate up to 73% of TSS and NH3-N, and 50% of phosphate. E. crassipes drastically removed 98% of phosphate, 96% of TSS, and 74% of NH3-N, while P. stratiotes was able to eliminate 98% of TSS, 78% of NH3-N, and 89% of phosphate. S. molesta was efficient in removing 89.3% of TSS and 88.6% of phosphate, but only removed 63.9% of NH3-N.

Organic matter, nutrients, and chemicals are some of the waste materials found in most domestic wastewaters. The purpose of this research was to evaluate the potentials of Pistia stratiotes, Salvinia molesta, and Eichhornia crassipes aquatic weed plants in the tertiary treatment of secondary domestic wastewater using hydroponic systems. Physicochemical analysis that considered turbidity, phosphate, ammoniacal nitrogen, and nitrate was conducted on the wastewater samples at different retention times of 6, 12, and 24 h for 14 days. The best performance was observed for a 24 h retention treatment system, with up to 91% (P. stratiotes), 94% (S. molesta), and 89.3% (E. crassipes) reduction for turbidity; 81.2% (P. stratiotes), 82.7% (S. molesta), and 88.5% (E. crassipes) for phosphate reduction; 88.66% (P. stratiotes), 90.47% (S. molesta), and 89.11% (E. crassipes) for ammoniacal nitrogen reduction; 83.6% (P. stratiotes), 92.1% (S. molesta) and 93% (E. crassipes) for nitrate reduction. Hence, the application of hydroponic systems in cultivation of the macrophytes proved to be effective in the phytoremediation process by removing the residual nutrients present in the treated secondary domestic wastewater. Additionally, this method can be used for the cultivation of plant-based biomass and other non-edible useful crops using the free nutrients content of the wastewater before its discharge into the natural environment.

Phytoremediation is an emerging low cost green technology, which uses plants for treating contaminant in the environment. Phytoremediation potential of locally available aquatic plants Eichhornia crassipes (water hyacinth), Pistia stratiotes (water lettuce) and Salvinia molesta (water fern) in the treatment process of textile wastewater was investi-gated. The reduction efficiencies of chemical oxygen demand (COD), total solids (TS), total suspended solids (TSS), total dissolved solids (TDS), nitrates, phosphates, heavy metals (Cd, Ni and Zn) and total and fecal coliform from the waste-water by each plant species were estimated. Bioconcentration factors (BCF) and translocation factors (TF) of three plant species for Cd, Ni and Zn were also estimated in order to identify their heavy metal absorption and translocation capacity. The results of the study indicated that greater reduction of COD, nitrates, phosphates, total coliform and Zn from the ini-tial wastewater by the three plant species. The results of the study also suggested that the selected aquatic plants are hy-peraccumulators of Cd, Ni and Zn metals. The findings of this study suggest that E. crassipes, P. stratiotes and S. molesta are potential aquatic plants for treating textile waste water.

Research was conducted to quantify the level of copper (Cu), chromium (Cr), cadmium (Cd) and lead (Pb) contamination in battery industry effluent and to assess the remediation potential of three invasive aquatic macrophytes Eichhornia crassipes, Pistia stratiotes and Hydrocotyle umbellata by growing on industrial effluent collected from Lead acid Battery industry.The effluent was heavily contaminated with Pb (10mg/l) and sulphuric acid (pH 2- 2.1). Due to high Pb concentrations and low pH (2-2.2) the plants were unable to survive. Mortality rate of E. crassipes was 96 % while P. stratiotes and H. umbellata were 100% rotten. The experiment was repeated after adjusting the effluent pH to 7-7.5 to increase the plant life.Plant parts and wastewater samples were analyzed after every 3 days interval uptil 21st day. The amount of Cr, Cd and Cu in the effluent was 0.076 mg /L, 0.036 mg /L and 0.097 mg /L, which was in permissible limits of NEQs (1.0 mg/l, 0.1 mg/l and 1.0 mg/l) respectively. Pb was found 10 times higher i.e. 10 mg/l than the permissible limit 0.5 mg/l. E. crassipes removed Pb>Cr>Cu>Cd while P. stratiotes and H. umbellata reduced Cd, Cr, Cu more than Pb from the effluent. E. crassipes was most efficient Pb removing plant in 21 days of experiment.

Durante o ano de 1999 foram conduzidos três experimentos em Botucatu-SP, em condições de caixas d'água, com o objetivo de estudar o efeito de alguns herbicidas sobre Pistia stratiotes, Eichhornia crassipes e Salvinia molesta. Os herbicidas e as doses utilizadas foram: diquat a 460, 960 e 1.400 g ha-1 com e sem o surfatante Agral a 0,1%; 2,4 D a 1.340; glyphosate a 3.360 g ha-1 mais 0,5% do surfatante Aterbane; e imazapyr a 250 g ha-1, além de uma testemunha sem aplicação de herbicida. Os estudos foram instalados no delineamento experimental em blocos ao acaso, com quatro repetições. As parcelas experimentais foram constituídas por caixas d'água com dimensões de 60 x 60 x 60 cm mantidas a pleno sol no campo. Utilizaram-se 18, 18 e 30 plantas/caixa de P. stratiotes, E. crassipes e S. molesta, respectivamente. Os herbicidas foram aplicados com pulverizador costal a pressão constante de CO2 a 1,75 bar, munido de barra com bicos 110.02 VS, com consumo de calda de 180 L ha-1. O herbicida diquat foi eficiente no controle de S. molesta, P. stratiotes e E. crassipes em todas as doses testadas. Para P. stratiotes, os herbicidas 2,4 D e imazapyr não proporcionaram controle, enquanto o herbicida glyphosate mostrou-se eficiente. Em relação a E. crassipes, os herbicidas 2,4 D e glyphosate foram eficientes em seu controle. Os herbicidas imazapyr, 2,4 D e glyphosate não foram eficientes no controle de S. molesta.

Aim: In this study, Ipomoea aquatica and Pistia stratiotes were used to remove total suspended solids, chemical oxygen demand and ammoniacal nitrogen (NH3-N) from the landfill leachate collected at Ampar Tenang Closed Landfill (ATCL) site in Dengkil, Selangor, Malaysia. Methodology: The physico-chemical characteristics of landfill leachate (pH, temperature, NH3-N, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total dissolved solids, total suspended solids, salinity, electrical conductivity and nitrite as well as selected heavy metals were determined before phytoremediation treatment. Results: The physico-chemical properties of leachate samples were found to be lower as compared to the standards set by the government, except for COD (>100 mg l-1). Heavy metals content, Na, Mg and Fe was high in leachate. It was found that the concentrations of NH3-N, COD and TSS in leachate decreased by 57.64%, 26.85% and 62.05% after treatment with Ipomea aquatica, respectively. Whereas, 61%, 32% and 74.7% removal rate was observed for NH3-N, COD and TSS, post-treatment by Pistia stratiotes. One-way ANOVA analysis for Ipomoea aquatica revealed insignificant difference (p>0.05) but for Pistia stratiotes there was a significant difference (p<0.05) in the reduction of TSS, COD and NH3-N concentrations. Interpretation: Based on the findings, Pistia stratiotes was found more effective than Ipomea aquatica for reducing TSS, COD and NH3-N concentrations from landfill leachate.
