Biological removal of pulp and paper mill TDS.

摘要

Pulp and paper mill is a major pollution generating industry. The aim of this research paper is to isolate autochthonous bacteria from the selected sites which can more effectively remove the TDS (Total Dissolved Solids) from the pulp and paper waste water. Treatment efficiency of combination of isolates was evaluated, followed by study of individual isolates comprising the consortium showing best result. Different consortia of isolated bacteria were able to reduce the TDS of pulp mill effluent in the range of 5.4%-12%, after 5 days of incubation. The individual bacteria comprising of the three best consortia (C3, C4 & C5) were screened individually. Among these, the isolate B11 (MTCC accession number 5098) showed the best TDS reduction of 12.2% after 48h of incubation.
