The moisture content of municipal solid waste (MSW) and local precipitation events lead to the leachate generation from MSW land lls. The high concentration of organic pollutants in land ll leachate makes it hazardous, requiring treatment before disposal into the environment. Land ll Leachate is most commonly treated by reverse osmosis (RO), which generates large volumes of wastewater termed as RO reject. This investigation aims to stabilize the RO reject through an inexpensive and effective bioremediation strategy. A bench-scale aerobic suspended growth reactor study was conducted using three commercial conversion agents, namely EM.1, Bokashi powder, and coir pith powder. Overall benchscale e cacy of 63% was achieved in this study. The onsite studies were conducted in 7.5 kL arti cial ponds with 46% e cacy amid atmospheric in uences and constraints. In contrast, the control pond with no conversion agents showed an increase in pollution concentration over the 100 days of retention time.The ndings revealed that the investigated technology had a marginally lower evaporation rate and performed relatively well compared to traditional solar evaporation ponds. Moreover, the technology can be easily scaled-up and readily applied for RO reject treatment in MSW land lls.

Overall bench-scale efficacy of 63% was achieved in this study. The onsite studies were conducted in 7.5 kL artificial ponds with 46% efficacy amid atmospheric influences and constraints. In contrast, the control pond with no conversion agents showed an increase in pollution concentration over the 100 days of retention time. The findings revealed that the investigated technology had a marginally lower evaporation rate and performed relatively well compared to traditional solar evaporation ponds. Moreover, the technology can be easily scaled-up and readily applied for RO reject treatment in MSW landfills.

Hybrid Phytoremediation: an Ultimate Bio-Solution for Leachate

Abstract: 60%. Thus, it's quite evident to claim the feasibility of the present study towards the bio-remediation of the enormous quantity of leachate generation associated with the handling of solid waste which is otherwise, a costly affair.
