INNOVATIVE APPROACHES TO WASTEWATER TREATMENT: INTEGRATION OF NANOTECHNOLOGY AND BIOLOGICAL PROCESSES

Abstract

The worsening state of water pollution with industrialisation and urbanisation has informed us that we must have more efficient, longer lasting and better wastewater treatment methods.  The paper examines the possibility of integrating nanotechnology and the biology to create a hybrid system capable of removing more pollutants.  With a complete experiment, it was arranged to determine the effectiveness of nano-bio systems in removing heavy metals, infections, organic and inorganic pollutants, and other contaminants present in various forms of environments.The overall plan resulted in the significant positive changes in the outcome of treatment.  Functionalised nanoparticles such as TiO 2, ZnO, and carbon nanotubes removed over 90 per cent of the material when used in certain cases.  Complex contaminants were broken down due to microbial activity that was optimised by maintaining the temperature and pH to some levels.  A combination of the nano-bio reactors was able to always remove pollutants, and the highest removal rates were 94.42 and more than 90% COD removal.  The kinetics of first order also indicated that the rate of degradation of contaminants is higher and research on bacterial growth indicated that nanoparticles are safe to be used at a given dose.There were 12 different graphs (such as COD reduction trends, pollutant category distributions, cost-efficiency graphs) which proved that the system performed best among others.  A review of the costs and use of energy indicated that the hybrid treatment reduced the cost per m3 whilst increasing the sustainability standards.  These findings demonstrate that nano-bio hybrid systems might assist in resolving some of the issues of modern wastewater processing approaches as they are more efficient, versatile, and cost-effective.  The research discovers that incorporating nanoparticles in the biological treatment system is a revolutionary method of handling the wastewater in an environmentally friendly and scalable manner.
