Effect 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...
متن کاملBiological Approach for the Treatment of Pulp and Paper Industry Effluent in Sequence Batch Reactor
Pulp and paper industrial effluent is rich in recalcitrant compounds and causes pollution. For the treatment of such compounds activated sludge process is frequently used in which F/M ratio is kept low. This treatment results in effective biochemical oxygen demand removal but other waste water parameters are not reduced effectively due to lack of dissolve oxygen. In the present study sequential...
متن کاملApplication of Trapa bipinosa for the treatment of pulp and paper industry effluent.
The ability of aquatic plants to absorb, translocate and concentrate metals has led to the development of various plant-based treatment systems. The potential to accumulate metals like iron, nickel, manganese and copper by Trapa bipinosa was assessed by subjecting them to different effluent concentrations of pulp and paper industry under laboratory conditions. Trapa showed the ability to accumu...
متن کاملTreatment 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...
