ELECTRO COAGULATION TREATMENT ON TANNERY BEAM HOUSE- SOAK LIQUOR BY HYBRID ELECTRODE COMBINATIONS

Waste water released from beam house operation of soaking process contains different kind of pollutants such as protein, lipids, greases and hairs produce high amounts of Chemical Oxygen Demand and Biological Oxygen Demand. Mainly tannery industries in TamilNadu, India follow solar evaporation pans. The waste water coming from soaking process contains high amount of Chemical Oxygen Demand and chloride concentration. The research work focus on soak processing waste water coming out from tannery industry by Electro Coagulation process using different electrodes. The removal efficiency only determined for Chemical Oxygen Demand and compared by different anode/cathode combinations Al/Fe, Fe/Graphite, Pt/Fe and Fe/Zn investigated

Treatability study of liming waste water in tannery by electro coagulation

The liming waste water from tannery industry creates more pollution problem with the environment. Liming waste water contains higher amount of COD (Chemical Oxygen Demand), sulfate, free ammonia and nitrate ion concentration. Lots of treatment methods have been tried by different authors, but the small industries could not give importance to install the treatment methods. So the drawback of liming waste water and the optimum treatment condition for the maximum above 90% removal of COD, TDS (Total Dissolved Solids), sulfate, nitrate, chloride and free ammonia by electro coagulation process with different pH, different electrolysis time and electrode distance with varying current density have been analyzed. Finally, the results discuss about the challenges of liming waste water by electro coagulation method

BIOLOGICAL STUDIES OF 4-AMINO BENZAMIDE DERIVED 1,2,3-TRIAZOLE LINKED CHALCONE AND ITS PYRAZOLINE DERIVATIVES

Objectives: The present work planned to investigate the anti-bacterial, anti-fungal, and anti-oxidant activity against 4-amino benzamide derived 1,2,3-triazole linked chalcone and pyrazoline derivatives. Methods: Anti-microbial activity for pyrazoline derivatives was accomplished by serial dilution method. The test organisms of bacterial strains were (Enterococcus faecalis, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas fluorescence) and the fungal cultures (Aspergillus niger, Aspergillus terreus, and Trichoderma harzanium). The method used in the anti-oxidant activity is 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide scavenging method. Results: All the compounds showed good to moderate anti-bacterial and anti-fungal activities. The results of IC50 values showed lower potent inhibition activity with DPPH and higher potent inhibition activity in nitric oxide scavenging method. Conclusion: All the compounds had exhibited capricious growth inhibitory effect on anti-bacterial, anti-fungal, and anti-oxidant activities

ANTIMICROBIAL ACTIVITY OF ASTRAGALUS MEMBRANACEUS AGAINST DIARRHEAL BACTERIAL PATHOGENS

Astragalus membranaceus (Fabaceae) is commonly used in medicine to treat a wide variety of infections. However, there is a lack of information on the effectiveness of A. membranaceus against microorganisms. The purpose of this study is to determine whether A. membranaceus inhibits bacterial growth in vitro. Methanolic and Ethanolic extracts of Astragalus membranaceus were prepared using dried root and were screened for phytochemical constituents. Tests for alkaloids, Saponins, Terpenoids, Flavonoids and cardiac glycosides were positive in both methanolic and ethanolic extracts. The evaluation of Antimicrobial activity of both the extracts was also carried out. The extracts were tested in disc diffusion assays against Diarrheal bacterial pathogens Escherichia coli, Salmonella enteritidis, Shigella, and Campylobacter. The results of antibacterial activity revealed that all the extract showed good inhibitory activity against all the tested pathogens. The activity of the extract was compared with standard antibiotics
