Potassium Ferrate

The potential implementation of Envifer®, a commercial product containing potassium ferrate (40.1% K2FeO4), for the purification of highly contaminated tannery wastewater from leather dyeing processes was proposed. The employment of the Taguchi method for optimization of experiments allowed the discoloration (98.4%), chemical oxygen demand (77.2%), total organic carbon (75.7%), and suspended solids (96.9%) values to be lowered using 1.200 g/L K2FeO4 at pH 3 within 9 min. The application of the central composite design (CCD) and the response surface methodology (RSM) with the use of 1.400 g/L K2FeO4 at pH 4.5 diminished the discoloration, the chemical oxygen demand, the total organic carbon, and suspended solids within 9 min. The Taguchi method is suitable for the initial implementation, while the RSM is superior for the extended optimization of wastewater treatment processes.

Removal Of Contaminants

In the present study a consortium of four naturally isolated bacterial strains was evaluated as remediation tool for simultaneous removal ofphenol and Cr (VI) from tannery effluent. Application of bacterial consortia to effluent (pH 4.6) resulted in 100 and 78% removal of initial 47mg L-1 phenol and 16 mg L-1 Cr (VI), respectively at 96 h of treatment. The consortium was also active in removal of contaminants with lowerremoval rate in presence of extraneous higher concentrations of both phenol and Cr (VI). Treatment in static mode also resulted in removal ofpollutants, however with increase in agitation speed simultaneous reduction of contaminants becomes faster. Overall it can be inferred fromthe study that the above formulated bacterial consortium could effectively be used for treatment of phenol and Cr (VI) laden tannery and otherindustrial effluents.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11889   Int J Appl Sci Biotechnol, Vol. 3(1): 50-55
