Abstract: Bioremediation in Wetlands attaches to itself the aesthetic as well as the
ecological value. It briefly explains the importance of wetlands and how they act
as a source of natural life in its environment. The work done widely involves
treatment of water samples taken from Sanjay Van Wetland area near the
Mehrauli ridge which is a notified reserved area under the WWN-DDA. The
concern is establishing a startup of incorporating this natural lake system in the
TERI university premises in the form of aquariums. The point of research here is
how the objectives that are taken can be incorporated so that someday it can be
implemented on field on a larger scale, after taking in account the literature
reviews and the methodologies that have been developed over time for this
decentralized technology to become cost effective. To accomplish the objectives
the plants and microalgae are cultured in the university and then different
concentrations of wastewater is exposed to five different species of plants and to
17 strains of bacteria in a single bacterium consortium and one species of
microalgae within a set time duration of 3 months to check selected
physiochemical parameters of this waste water including DO, BOD, TDS, pH,
conductance, TSS, biomass estimation and the rate of evaporation. The
experimental analysis was found to successful and there was ample amount of
decrease visible in the BOD parameter of the water sample taken enhancing it
further for applications that can be drawn as a benefit to humans.
