Treatment of pulp and paper mill wastewaters with poly

Poly aluminium chloride (PAC) Pulp and paper mill effluents 1. Introduction Paper industry consumes large amount of water (about 250¨C300 m 3 /t of paper produced) and generates almost an equal amount of wastewater having high biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity and colour.

Treatment of pulp and paper mill wastewaters with poly

The present study deals with the use of poly aluminium chloride (PAC) as a coagulant and bagasse fly ash (BFA), which is generated in sugar mills, as an adsorbent for the removal of chemical oxygen demand (COD) and colour of pulp and paper mill effluents.

Treatment of wastewater effluents from paper-recycling plants

In the present study, a coagulation process was used to treat paper-recycling wastewater with alum coupled with poly aluminum chloride (PACl) as coagulants. The effect of each four factors, viz. the dosages of alum and PACl, pH and chemical oxygen demand (COD), on the treatment efficiency was investigated.

Impacts of poly-aluminum chloride addition on activated

As a common and low-cost coagulant, poly-aluminum chloride (PAC) may be widely used for wastewater treatment. In this article, the impacts of PAC on activated sludge and the treatment efficiency of sequencing batch reactor were investigated over 100 d for domestic wastewater treatment.

Cost-effective removal of COD in the pre-treatment

Under the optimal operational conditions (pH = 7.5, T = 18 ¡ãC) the treatment of wastewater from paper industries by coagulation has led to a reduction of 70% COD for wastewater discharged. In terms of the investigated paper industry wastewater, polyaluminium chloride appears to be most suitable for treatment of high COD concentration.

Irfan et al. reported that aluminum chloride was exceptionally better at reducing the color of pulp and paper mill wastewater than ferric chloride, ferrous sulphate, and poly aluminum chloride. Studies on the organic matter characteristics of effluent from different papermaking processes help determine the treatment strategy of RPPW (Wang and

ABSTRACTThis study evaluates the effectiveness of polyaluminium chloride (PAC) as a coagulant for the treatment of pulp and paper mill wastewater. The wastewater was characterized for different chloro-organic compounds, i.e. adsorbable organic halides (AOX), chlorophenolics, and chlorinated resin and fatty acids (cRFA).
