Research ArticleOpen accessEvery word in the titleTreatment of Organic Compounds of Landfill Leachate in Vietnam by Combining Coagulation and Ozonation ProcessVan Huu Tap, Trinh Van TuyenLandfill leachate is a problematic pollution that should be solved in Viet Nam. This study presents some experimental results of removals of COD and color from landfill leachate by using coagulation and ozonation processes to determine the optimal reaction conditions. In pre-treatment stage by coagulation, the results showed that the removals obtained from three types of coagulants showed a maximum … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 23 Jan 2014 · 7,118 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAerobic Biodegradation of Per-Treated Methyl Tert-Butyl Ether By Ozonation in an Up-Flow-Fixed-Bed ReactorM. Sadeghi, M. Arbabi, A. Nikpey, G. MardaniProblem Statement: MTBE is a common pollution of environmental and has become an issue of considerable concern in recent years. It is not readily amenable to remove MTBE by conventional techniques in water treatment. In the present study, the feasibility of the continuous aerobic biodegradation of MTBE, was evaluated in an Up- Flow Fixed Bed Reactor (UFBR). Approach: The UFBR … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,620 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleApplication of the Ozonation Pre-treatment for Biodegradation of Aqueous Solutions of Methyltert-Butyl EtherM. Sadeghi, A. Mesdaghinia, A. Badkoubi et al.The effectiveness of ozone treatment for improving the biodegradability of recalcitrant pollutants has been proved by investigating the ozonation reaction of Methyl tert-butyl ether (MTBE) a bioresistant gasoline oxygenate. Laboratory scale experiments have been carried out, at room temperature, by bubbling, for 120 min, ozonated air (3.4 ppm min-1 ) into 3 liter of an alkaline (pH=11.5) aqueous solution (100 … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,463 accessesView PDF Cite
