The Effectiveness of Filter Media and Echinodorus palaefolius on Phytoremediation of Leachate

This research aims to know the effectiveness of filter media and Echinodorus palaefolius on phytoremediation of leachate. This research was conducted at greenhouse Faculty of Agriculture, Lancang Kuning University. The method used was an experimental method by using a completely randomized design, wich consists of 4 treatments with five replicates at each treatment. The parameters measured were turbidity, temperature, total suspended solids (TSS), pH, and dissolved oxygen (DO). Data were analyzed by using Analysis of Variance and a further test with Duncan’s Multiple Range Test at a significant level (α) = 0.01. The results showed that there was a significant effect of filter media with Echinodorus palaefolius on phytoremediation of leachate. to reduce levels of pollutants found in leachate. treatment P3 (PMK, zeolite, Echinodorus palaefolius) with a value of effectiveness were 95,18% for turbidity, 97,47% for TSS, 20.86% for pH and (-) 6660% for DO.

Phytoremediation of landfill leachate

Leachate emissions from landfill sites are of concern, primarily due to their toxic impact when released unchecked into the environment, and the potential for landfill sites to generate leachate for many hundreds of years following closure. Consequently, economically and environmentally sustainable disposal options are a priority in waste management. One potential option is the use of soil–plant based remediation schemes. In many cases, using either trees (including short rotation coppice) or grassland, phytoremediation of leachate has been successful. However, there are a significant number of examples where phytoremediation has failed. Typically, this failure can be ascribed to excessive leachate application and poor management due to a fundamental lack of understanding of the plant–soil system. On balance, with careful management, phytoremediation can be viewed as a sustainable, cost effective and environmentally sound option which is capable of treating 250 m 3 ha −1 yr −1. However, these schemes have a requirement for large land areas and must be capable of responding to changes in leachate quality and quantity, problems of scheme establishment and maintenance, continual environmental monitoring and seasonal patterns of plant growth. Although the fundamental underpinning science is well understood, further work is required to create long-term predictive remediation models, full environmental impact assessments, a complete life-cycle analysis and economic analyses for a wide range of landfill scenarios.
