Abstract

Phytoremediation is a widely recent studied and applied technology, using various plants to remediate contaminants from wastewater by extraction, containment or destruction method which also known as eco-friendly and cost-effective techniques compared to conventional processes. The huge increased of palm oil production industry has become major environmental concern but not much have been said about the negative effects. Three major waste streams in processing palm oil were gaseous (pollutant gases), liquid (POME) and solid (palm press fibre, chaff, palm kernel shell and empty fruit bunch). The aim of this study was to determine the potential of water lettuce (Pistia stratiotes) and duckweed (Lemna minor) in removing contaminants in POME. Seven water quality parameters based on Sewage and Industrial Effluent Discharge Standards were selected in this study like pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), iron (Fe) and zinc (Zn). POME sample were placed in 3 basins for 28 days; (basin 1 – control, basin 2 – duckweed, Basin 3 – water lettuce), and each basin were tested with different retention time. The results showed that both studied plants have positive result as phytoremediation agents effectively in removing contaminants of POME. To achieve optimal contaminant reduction, incorporate a combination of phytoremediation and other complementary treatment would be beneficial before POME release into waterways.

Abstract

Landfill leachate, a contaminated liquid produced from rainwater passing through waste materials, presents serious environmental risks by polluting soil and water sources. This study examines the potential of water spinach (WS) (Ipomoea aquatica), water hyacinth (WH) (Eichhornia crassipes), and marsh pennywort (MP) (Hydrocotyle umbellata) to remove heavy metals from landfill leachateIt evaluates levels of heavy metals such as zinc (Zn), copper (Cu), and iron (Fe) to assess the effectiveness of pollutant removal. Leachates from landfills were distributed among four basins over a period of 28 days; (Basin 1 – control, basin 2 – water hyacinth, basin 3 – water spinach, basin 4 – marsh pennywort) and each basin underwent testing with different retention times. The results proved substantial decrease in all of the selected heavy metals (Zn, Cu and Fe) levels after treatment with WH, WS and MP. All the aquatic plants demonstrate an ability to absorb heavy metals, leading to lowered concentrations in the leachate. These findings highlight WH, WS and MP promise as phytoremediation tools for managing landfill leachate contamination that can help to combat pollution and safeguard water resources. This project aims to compare how effectively WS, WH and MP, with various exposure times, can eliminate heavy metals.
