Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIsolation and Identification of a Bioflocculant-Producing Strain and Application in Rice Vinegar ClarificationWeilian Hu, Dehui DaiA bioflocculant-producing bacterium S-3# was isolated from fresh sand bones 40-50 cm underground in the desert region of China’s Ningxia Province. It was identified as Paenibacillus sp. based on 16S rDNA sequence along with its biochemical and morphological characteristics. Chemical analysis found that the bioflocculant from S-3# is mainly composed of extracellular polysaccharide. Researchers observed no noticeable change (above 91%) … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 30 Dec 2020 · 5,924 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTreatment 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
