Abstract
Paper industries play an important role in the world’s economy. The paper industry generates a huge amount of effluent and contains a high strength of organic and inorganic pollutants load. Different types of chemicals like sodium hydroxide, sodium carbonate, and chlorine compounds have been used during the paper-making process. These chemicals are highly responsible for high amounts of biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), and total suspended solids (TSS), etc. Floating treatment wetlands (FTWs) technology proven as cost-efficient and aesthetically pleasant technology to treat different types of industrial effluents. The current study deals with the remediation of paper mill effluent by the combined used of macrophytes and bacterial consortium. Two bacterial strains SZ1 and LGW-6 inoculated as consortium to Typha domingensis (southren cattail) in FTWs to evaluate their capacity to detoxify the paper mill effluent. In green house experiment, the reduction in the BOD (87%), COD (93%), and TDS (94%) were observed in T2 where T. domingensis and bacterial consortium were applied in FTWs. Moreover, .highest biomass production, root and shoot length was observed in T2. We concluded that FTWs is the effective and reliable approach for the remediation paper mill effluen
