Evaluation of the Coagulation and Flocculation Process Using Plantago major L. Seed Extract as a Natural Coagulant in Treating Paper and Paperboard Industry Wastewater
Introduction: Paper and paperboard industry wastewater has potentially damaging effects on the ecosystem of the receiving environments due to the presence of toxic compounds. As a result, the treatment of such wastewater is necessary prior to discharge into the environment. In this study, the potential of Plantago major L. seed extract as a natural coagulant in treating paper and paperboar...
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...
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 کاملOptimization of Coagulation and Flocculation Process in Wastewater Treatment of the Food Industry: A Laboratory Study
Background and Objectives: Food industry wastewater has a high pollution load, which is due to water consumption at various stages. In the absence of adequate wastewater management and supervision of the food industry, this wastewater can be considered as a source of environmental pollution. This study aimed to optimize the coagulation and flocculation process for the treatment of food industry...
متن کاملWastewater from wood and pulp industry treated by combination of coagulation, adsorption on modified clinoptilolite tuff and membrane processes.
Wastewater from the wood and pulp industry is of environmental concern. It contains high concentrations of organic and inorganic matter. In this work a combined method of coagulation, adsorption and nanofiltration/reverse osmosis (NF/RO) was investigated in the purification of biologically treated wastewater from wood processing. Coagulation with 0.8 g dm(-3) AlCl3 x 6H2O and adsorption on 2.5 ...
