Abstract
Water quality has received considerable attention in allocation processes formaximizing the satisfaction of various sectors. However, pollutant impurities that impedeadequate supply of water have a detrimental effect on the quality and harmful for livingorganisms including aquatic life. For the reduction of water pollution level, variouschemical and biological treatments are available but the emergence of an amazingtechnology of a multiculture of anaerobic and aerobic beneficial microorganisms ispresently gaining popularity due to its environmentally friendly nature. This effectivemicroorganism (EM) technology uses naturally occurring microorganisms which are ableto purify and revive nature. Applications of EM using the formula known as effectivemicroorganism activated solution (EMAS) have been experimented in several rivers inMalaysia depending on the scale, location, physical and geographical conditions with theprincipal objective of enhancing and improving the water quality. One of the significantcontributions of EM based rehabilitation of polluted and degraded water bodies is to restoreaquatic habitats and ecosystems. Existing results of projects via EM technology in solvingwater quality related problems, and the nationwide campaigns in Malaysia are dulypresented. The role of EM-based water restoration approach for sustainability of waterresources and prospects of modeling are also discussed. Results clearly demonstrated theeffectiveness of this technique for restoration of water quality of degraded/polluted riverbasin. Valuable lines for further research and acceptance of EM technology for the futureare thus suggested as it is believed to be the key to sustained environmental improvementand offers a real opportunity for eco-innovation.
