...e, calcium hypochlorite (bleaching powder), Virkon®S and Peraclean®. The purpose from using the Egyptian H5N1 viruses in the evaluation was to achieve maximum simulation of Egyptian field reality as the two viruses represent the two main subclades currently co-circulating in Egypt. The disinfectants were tested individually for effectiveness against HPAI H5N1 for 5, 10, 15 and 30 minutes contact time. Numerical method and neutraliza...

TREATMENT FEASIBILITY OF THE BLEACHING EFFLUENT OBTAINED FROM NSSC PULP AND PAPER MILL IN A UASB REACTOR

...atability of actual bleaching effluent obtained from NSSC pulp and paper mill at mesophilic temperature and neutral pH. Methanol as a source of an easily biodegradable substance along with an activated carbon of effective size 1.5-2.5mm was added to the reactor R-I to evaluate its efficiency. It was observed that corresponding to an OLR of 2.14kg-COD/m3-day the overall COD removal efficiency of the reactors R-I and R-II was 83% and 64%...

...DE). The β-carotene bleaching inhibition of 87.44 ± 1.20% was computed for 60% ethanolic leaf extract being statistically non-significant from BHA (89.41 ± 2.45%). The in-vitro anti-obesity attribute of extracts was assessed by measuring the inhibition of enzymatic activity of pancreatic lipase. The 60% ethanolic leaf extract exhibited maximum pancreatic lipase inhibition of 54.55 ± 0.72% but lower than standard drug orlistat (66.65 &...

... screening, three stages bleaching of pulp was carried out by chlorination, alkali extraction and hypochlorite bleach. Facilities for the fourth stage were not available and therefore, a low pulp brightness of 750 GE was attained. The bleached supphate pulp was evaluated in the form of mixed furnish for the manufacture of different grades of paper and paperboard and its quality was compared with imported long fibre pulp used for the same purpose. The strengt...
