A Study on the Reduction of Chlorinated Organics in Bleach Plant Effluent by Oxidation with Oxygen
The removal of chlorinated organics from the E, effluent by oxygen oxidation treatment was studied. It was found that the reduction of TOCI and colour from the fraction of highmolecular-weight chlorolignins is vitally important to the overall reduction of TOCI and colour from the El effluent. Three pathways are potentially involved in the removal of TOCI and colour from the E, effluent: degrada...
متن کاملTreatability studies on bleach effluent of pulp and paper industry by ultraviolet/hydrogen peroxide process with titanium dioxide as catalyst
The treatment of bleach effluent from pulp and paper Industry for COD, colour and AOX removal was investigated using Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide. The Ultra violet / Titanium dioxide process was able to remove 48% and 37% of COD and colour. The Ultra violet / Hydrogen peroxide process was able to remove 52% and 59% of COD and colour. The combined pro...
متن کاملStudies on the Removal of AOX from Bleached Kraft Mill Effluent with Bark Boiler Ash
A laboratory study was carried out to determine the effect of bark boiler ash on AOX concentration in bleach plant effluent. The removal of A O X was found not to be significant at typical daily discharge rates of boiler ash. To remove significant amounts of AOX, extremely large quantities of ash were required. When incremental quantities of ash were added to the bleach plant effluent, an incre...
متن کاملRemoval of contaminants in a paper mill effluent by Azolla caroliniana
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...
متن کاملTreatment of rayon grade pulp drain effluent by upflow anaerobic fixed packed bed reactor (UAFPBR).
The Rayon grade pulp (RGP) drain effluent of pulp and paper mill was studied to find out pollutant loading and its control measures by low cost and efficient treatment method. Upflow anaerobic fixed packed bed reactor (UAFPBR) with brick ballasts as packing material was used for this purpose. This was compared with conventional anaerobic treatment method. The digested slurry was taken as inocul...
