Treatment 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 کاملFeasibility of Typha and Canna for pulp and paper mill wastewater treatment through small wetlands
The bucket reactors based wetland system were adopted for the treatment of pulp and paper mill wastewater using two macrophytes namely Typha angustifolia and Canna indica. The study was carried out for the treatment of wastewater collected from primary clarifier overflow (E1) and wastewater after the partial aerobic treatment of primary clarifier overflow (E2). Effectiveness of the two macrophy...
متن کاملColor and phenolic compounds reduction of Kraft Pulp Mill effluent by ozonation with some pretreatments
A study on the treatment of Kraft pulp mill effluent by ozonation alone, and by combined treatment of ozonation preceded by chemical coagulation, activated carbon adsorption or membrane filtration has been conducted. Initial effluent pH was a major factor deciding the treatment efficiency. When ozonation was conducted alone, more than 70% reduction of color and phenolic compounds could be achie...
متن کاملBioremediation of paper and pulp mill effluents.
Pulp and paper mill effluents pollute water, air and soil, causing a major threat to the environment. Several methods have been attempted by various researchers throughout the world for the removal of colour from pulp and paper mill effluents. The biological colour removal process uses several classes of microorganisms--bacteria, algae and fungi--to degrade the polymeric lignin derived chromoph...
متن کاملProposed Wastewater Treatment Plant for a Paper Mill
The decline in the availability and alarming pollution of the existing water resources is the major environmental problem of third-world countries. The main reason of water pollution is the disposal of untreated industrial effl uents. This study was designed to evaluate the pollution load caused by a paper mill, and to propose a wastewater treatment plant design, based on the analyses of wastew...
