Bacillus pumilus and Paenibacillus sp. were applied on the paper mill effluent to investigate the colour remotion. Inocula were individually applied in effluent at pH 7.0, 9.0 and 11.0. The real colour and COD remotion after 48h at pH 9.0 were, respectively, 41.87% and 22.08% for B. pumilus treatment and 42.30% and 22.89% for Paenibacillus sp. Gel permeation chromatography was used to verify th...

this study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by azolla caroliniana.  the experimental investigations have been carried out using azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), ph (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). the maximum removal ...

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) proce...

The Rayon grade pulp (RGP) drain effluent of pulp and paper mill was studied to find out pollutant loading and its control measures by low cost and efficient treatment method. Upflow anaerobic fixed packed bed reactor (UAFPBR) with brick ballasts as packing material was used for this purpose. This was compared with conventional anaerobic treatment method. The digested slurry was taken as inocul...

In the present study sequential anaerobic and aerobic treatment in two step bioreactor was performed for removal of colour in the pulp and paper mill effluent. In anaerobic treatment, colour 50%, lignin 62%, COD 29%, absordable organic halides (AOX) 25% and phenol 29% were reduced in eight days. The anaerobically treated effluent was separately applied in bioreactor in presence of fungal strain...

normal 0 false false false en-us x-none fa background: nowadays wastewater is one of the important sources of environmental pollutions and   one of the aims of wastewater treatment is to maintain a healthy environment. nonstandard wastewater discharges and their use in agriculture or discharge to surface water will follow environmental and health hazards. the aim of this study was to compare th...
