Biological Treatment Technology for Landfill Leachate

Abstract

Biological process for environmental preservation and treatment is not a new technology. It was used a decade ago until now. The most important tools in biological processes are the microorganism and upstream instruments (bioreactor, pond and others) to run the process. Furthermore, the efficiency of the process depends on many factors such as temperature, pH, type of microorganism, conditions, and other nutrients. To understand the factors that will affect the process, mechanisms of microorganisms to treat or protect the environment must be considered. For leachate treatment, biological process is one of the most widely used techniques for low cost and environmentally friendly.

“…Although both physical and chemical methods have been successfully applied to treat the landfill leachate within a short duration, these techniques are usually expensive and may lead to the unexpected secondary pollution of the environment [8][9][10]. Therefore, the biological methods are widely considered to be more appropriate for long term treatment of the landfill leachate [44]. However, biological processes often deal with system instability and deterioration of its performance under different stresses [13].…”
