Background and purpose: Pulp and paper industries produce large quantities of effluent that release various pollutants daily. Among various methods for treating such effluents, anaerobic biosorption process is of interest because of lower need to mechanical energy, boigasses production, high organic loading rate (OLR), low sludge production, and resistant system. OLR is one of the most importan...
This study investigates oxidative stress and bioindicators of reproductive function in wild white sucker (Catostomus commersoni) collected from environments receiving pulp and paper mill effluent discharges in northern Ontario. Samples were collected over an eight-year period adjacent to three pulp and paper mills using a variety of processing and bleaching techniques. Fish collected downstream...
Pulp and paper mill effluent is posing a serious threat to the water and soil components of the environment due to its brown colour and high level of toxicity. Fungal treatment is one of the efficient methods for treating pulp and paper mill effluent. In the present study, for the treatment of from pulp and paper industry, nine efficient fungal strains including Phanerochaete chrysosporium, ded...
The experiments were carried out in an electro coagulation reactor with aluminum as sacrificial electrodes. The influence of electrolysis time, current density, pH, NaCl concentration, rotational speed of the stirrer and electrode distance on reduction of color, COD and BOD were studied in detail. From the experimental results, 25mA/cm2 current density, pH of 7, 1 g/l NaCl, 100 rpm, 28 ◦C tempe...
