This study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by Azolla caroliniana.  The experimental investigations have been carried out using Azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). Th...

To eliminate hazardous hexavalent chromium from a brass wire-mill waste, hydrogen peroxide was examined In place of chromic acid for pickling, first in bench-scale tests and then in plant tests. Nthough the elimination of chromic acid requires more rigid control of the ~ wastewater treatment operation and increases the zinc content of the waste-treatment effluent, the economic benefit of substi...
