Treatment of Paper and Pulp Mill Effluent using Sequential Batch Reactor
The manufacture of paper generates significant quantities of waste water; which can have deleterious effects on the receiving waters; therefore there is a need to find a treatment process which can minimize these effects considerably. The raw wastewater from paper and board mills can be potentially very polluting. This paper reveals the results of laboratory experiments using a sequential batch...
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 کاملBiodegradation of pulp and paper mill effluent using anaerobic followed by aerobic digestion.
An experimental study was carried to find out the degradability of black liquor of pulp and paper mill wastewater for biomethanogenesis in continuous stirred tank reactor (CSTR) and followed by activated sludge process (ASP). Continuous stirred tank reactor was used in present study for anaerobic digestion of black liquor, while completely mixed activated sludge system was used for aerobic dige...
متن کاملColiform bacteria and nitrogen fixation in pulp and paper mill effluent treatment systems.
The majority of pulp and paper mills now biotreat their combined effluents using activated sludge. On the assumption that their wood-based effluents have negligible fixed N, and that activated-sludge microorganisms will not fix significant N, these mills routinely spend large amounts adding ammonia or urea to their aeration tanks (bioreactors) to permit normal biomass growth. N(2) fixation in s...
