Bioremediation of Polluted Kamla River Water by Physical, Biological and Ecological Processes

Abstract

The increasing need for remediation of contaminated sites has led to the development of new technologies that emphasize on the biological detoxification anddestructionofthe(organic)contaminants.Bioremediationisamongthesetechnologiesthatdestroyorrenderharmlessvariouscontaminants,usingthebiologicalactivityofcertainmicroorganisms[1].Needlesstosaythatasbioremediationactuallyreliesonthemicrobialgrowthandactivity,itseffectivenessishighlydependentontheappliedenvironmentalparametersthatinfluencethemicrobialgrowthandthedegradationrate.Bioremediationtechnologiescanbeclassifiedintotwogeneralcategories:exsituandinsitu.Theexsitutechniquesarethosethatrequirethe physical removal of the contaminated material and its transportation to another area for further treatment, for example, by bioreactors, landfarming and composting.

Phytoplankton Dynamics and Its Relation to Physicochemical Parameters in the Dry Season of Maninjau Lake, West Sumatra, Indonesia

“…In contrast to M. aeruginosa, S. acus has a beneficial impact on aquatic biota as a food source for young and adult fish. Simultaneously, S.acus is helpful for fisheries and a biological indicator of pollution (Kumar & Jha, 2015). Synedra biomass reaches its maximum during a spring diatom bloom in Lake Paldang, Korea, at higher temperatures and Silicon: TP ratio >20 (Youn et al, 2020).…”
