Treatment of Pulp and Paper Effluent by Electro coagulation
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...
متن کاملTreatment of paper and pulp mill effluent by coagulation.
Pulp and paper mill effluent is highly polluting and is a subject of great environmental concern. In the present research we studied the removal of chemical oxygen demand (COD) and colour from paper mill effluent, using the coagulation process. A batch coagulation study was conducted using various coagulants such as aluminium chloride (AlCl3), polyaluminium chloride (PAC) and copper sulphate (C...

متن کاملEffect of Metal Salt Coagulants on Treatment of Activated Sludge Effluent in Sulfite Mill Pulp and Paper Plant
Pulp and paper effluents are considered as serious environmental hazards and their treatment, because of multiplicity of impurities and complexity of their chemical structures, is one of the most difficult and inconvenient industrial processes. As the most pulp and paper mill work on kraft process, there are few studies in literature on the treatment of neural sulfite semi chemical (NSSC) p...
متن کاملutilization of electrochemical method (ec) for pulp and paper mill industry's effluent treatment
growing the water consuming and shortage of available fresh water resources, make “effluent reuse” an unavoidable issue in industry for supplying a part of needs for required water. on the other hand, increment in the production of paper products from wood and recycling their consumed products which release pollutants to the environment has increased the environmental concerns. thus, in present...
