landfill leachate treatment in jet-loop membrane bioreactor operated under different organic loading rates
نویسندگان
چکیده
since treatment of landfill leachate is quite complicated, there is a need to develop a system thatis capable of providing high treatment efficiencies. in this study, the treatment performance of a jet - loopmembrane bioreactor (jlmb) operated at different organic loading rates was investigated by observing thechanges in chemical oxygen demand (cod), total kjehldahl nitrogen (tkn) and total ammonia (nh3)concentrations. the same cod removal rates (83%) were observed at all the studied loading rates, and itshould be noted that the biodegradable part of the leachate was removed completely. it was also observed that the nh4 – n / tkn ratios, which were found to be approximately 0.9, did not change throughout the study. however, further treatment technologies, such as reverse osmosis, nanofiltration or ion - exchange, should be employed for the complete removal of inert cod and nh3 in order to meet related discharge limits.

متن کاملReview on Membrane Bioreactor, Ion Exchange and adsorption Methods for Landfill Leachate Treatment
Urban landfill leachate is a high strength wastewater characterized by high concentrations of recalcitrant organic compounds, ammonia and, increasingly, arsenic. The aims of this study were the review on membrane bioreactor, ion exchange and adsorption method for landfill leachate treatment. Membrane bioreactor (MBR) can be used for wastewater and landfill leachate treatment. The most important...
متن کاملAn Autopsy of Nanofiltration Membrane Used for Landfill Leachate Treatment
Komurcuoda leachate treatment plant, Istanbul, which consists of membrane bioreactor (MBR) and nanofiltration (NF) system, faced rapid flux decline in membranes after 3-year successful operation. To compensate rapid flux decline in membranes, the fouled membranes were renewed but replacement of the membranes did not solve the problem. To find the reasons and make a comprehensive analysis, membr...
متن کاملLandfill Leachate Treatment through Electro-Fenton Oxidation
Advanced Oxidation Processes (AOPs) have been employed to degrade biorefractory organic matters. This study investigates the combination of classical Fenton reaction with electrochemical oxidation, the electro-Fenton process, for the treatment of semi aerobic landfill leachate, collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. The investigation has been carried out in batch re...
متن کاملPolluting potential of post-Fenton products in landfill leachate treatment
Fenton process, as one of the most conventional advanced oxidation processes, is widely used in the treatment of specific wastewaters, especially landfill leachate. In current study, the main target was to evaluate some neglected aspects of Fenton process in operational applications. Thus, three novel responses were introduced. Mass removal efficiency evaluates overall recalcitrant destruction ...
