Abstract

Surface water pollution with organic contaminants is one of the most intractable environmental problems today. Major source of the contaminants are coming from the agriculture activities via fertilizer run-off which may lead to eutrophication phenomenon. The excessive use of fertilizer to assure high yields in the agriculture production intensifies the surface water problem. Innovative strategies for remediating organic-contaminated surface waters are critically needed. Phytoremediation, based on synergistic action of plants and their associated microorganisms has been recognized as a remarkable green technology approach in surface water treatment. With a right plant, the biodegradation of organic contaminants are enhanced, dramatically expediting the removal of organic pollutants from surface water. The potential of lotus plant to reduce the contaminated surface water is demonstrated due to its gas transportation mechanism for supplying O2 gases from the water surface to the plant rhizomes that located beneath the underwater soil area. In this study, the role of lotus plant has been compared with the laboratory scale for polishing the contaminated surface water. Throughout the 30 days of phytoremediation process, the application of lotus plant was able to treat contaminated water with the BOD and COD removal efficiency of 78.33% and 50% respectively. The laboratory scale study, which consist of 5 μm soil and 10 μm soil indicated with the BOD removal efficiency of 96.1% and 93.4% respectively. The COD removal efficiency was indicated by 58.9% and 60.2% respectively. Without the soil inclusion, the plant treatment abilities for BOD and COD removal efficiency was increased up to 97 .1 % and 55.0% respectively. However, the plant survival was limited without the soil inclusion and the water treatment using finer soil particles size is recommended for future work.
