“…It was indicated that each plant that acts as phytoremediation agent has its own efficiency rate in removing different pollutants. However, there are several factors that may affect the reduction percentage of contaminants, such as the type of pollutant and wastewater, treatment duration and pollutant concentration [52][53][54].…”

The rapid growth of industries has resulted in wastewater generation containing different organic and chemical substances channeled into the water body. This causes the arising of water pollution issues in many regions. The phytoremediation method was introduced in the process of treating water pollution as it is low cost and environmentally friendly. Lemna minor, Salvinia minima, Ipomoea aquatica and Centella asiatica were chosen in this study because they have tolerance to various pollution conditions and are able to remove organic pollutants and heavy metals. The objectives of this study were to determine the water quality before and after treatment, to determine the rate of reduction in total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and chemical oxygen demand (COD) in sewage water through the phytoremediation method and to assess the effectiveness of the plants in the phytoremediation of sewage wastewater. It was found that, Lemna minor, Salvinia minima, Ipomoea aquatica and Centella asiatica were able to reduce TSS by 50.8%, 77.6%, 85.6% and 67.6%, respectively; NH3-N by 80.4%, 89.9, 97.3% and 79.1%, respectively; and COD by 75%, 82%, 44.8% and 36.46%, respectively. In this study, it was found that sewage wastewater treatment using Ipomoea aquatica was more efficient in reducing NH3-N and Salvinia minima was more efficient in reducing TSS and COD values.

Leachate has the potential to contaminate groundwater and the environment due to the high quantity of toxins it contains (8,11). Leachate typically has high Chemical Oxygen Demand (COD) values, ranging from 6000 to 60000 mg/L, and Biological Oxygen Demand (BOD) levels between 4000 and 13000 mg/L (12).…”

Introduction: Bali, as an international tourist destination, is still experiencing problems in waste management. Suwung Landfill, Denpasar, is one of the landfills for waste originating from the Denpasar, Badung, Gianyar, and Tabanan (Sarbagita) areas. Methods: This research was an experimental study, by watering eco-enzymes on garbage heaps and examining changes in leachate parameters. Watering was carried out daily at a dose of 1 L of eco-enzyme dissolved in 1000 L of water and used for watering a garbage pile of 1 ha. The area of piles of garbage watered with eco-enzymes reaches 5 ha. Measured leachate parameters include pH, BOD, COD, TSS, N, cadmium, and mercury. Results and Discussion: Eco-enzymes have the potential to become activators or decomposers in waste composting. The evidence is that eco-enzyme watering causes the average leachate temperature to range from 36.63 to 40.370C, where the increase in leachate temperature occurs due to the rise in the temperature of the garbage pile. An increase in temperature characterizes the activity of microbes increases, so the decomposition process becomes rapid. Conclusion: Eco-enzyme spraying leads to a characteristic change in the form of an increase in the value of leachate parameters. The increase in temperature value, pH, BOD, COD, and N content of leachate indicates that environmentally friendly enzymes accelerate the decomposition of organic matter. The rapid decomposition process causes the total suspended density of leachate to increase.

“…In the case of municipal solid waste disposal sites, leachate is generated during the process of decomposition of solid waste (Halim et al, 2017). The main problems associated with waste disposal sites are the production of leachate and release of harmful CH gas (Banch et al, 2020b). 4 The release of leachate from landfill in the environment is a concern due to toxic nature of leachate that can have deterioration effects on human health (Banch et al, 2019b).…”

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.
