Abstract
Rivers are the lifeline of an ecosystem, since every member of the ecosystem depends directly or indirectly upon them for their sustenance. Changes in the riparian conditions would strongly impact the ecosystem-to-organism interactions and inter-organism interactions. Due to lack of regulations and widespread use of technology for industrial wastewater treatment, most of the industrial discharge ends up in the river. This leads to increased toxicity and river pollution and can be remedied only through restoring the ecological conditions of the river. Eco-restoration of rivers is meaningless without addressing the reason behind river pollution hence feasible industrial wastewater treatment methods are discussed in this study, with emphasis on their practicality and effectiveness.
Highlights
Rivers, by themselves, can be termed small- scale bio diversity hotspots since they sustain and support a lot of ecological communities and inter-species interactions
When the current density increased from 50 to 100 mA/cm2, the results showed that the efficiency of TOC removal increased from 28.5 to 34.42%. (Bener et al, 2019) Distance between the electrodes: For effluents with high electrical conductivity, which are supplied with constant current, distance between the anode and cathode must be increased (Bener et al, 2019) Effect of applied voltage on metal removal: The result at 8 V showed that the maximum removal of metals was found to be 96, 98 and 99.5% for Cr, Cu and Pb, respectively (Bener et al, 2019)
Nano-catalysts: In industrial wastewater treatment, metal oxides and semiconductors are used as electrocatalysts to inprove the performance of the fuel cells and Fenton based catalysts are used for improving chemical oxidation of organic pollutants (Chaturvedi et al, 2012)
