Review on Applications of Nanoparticles in Landfill Leachate Treatment

Abstract:

Sanitary landfill is the most common way to eliminate solid waste. However, sanitary landfill generates large quantity of leachate. Leachate can be defined as a liquid that passes through a landfill and extracted dissolved and suspended matter. The presence of large quantity of contaminants in leachate is harmful to human and ecological environment. This can lead to health issues, including gastrointestinal illness, reproductive problems, and neurological disorders. There are several significant techniques have been made to overcome the problem of leachate pollution, including photocatalytic oxidation, adsorption/separation processing and bioremediation. However, the applications have been restricted by many factors, such as processing efficiency, operational method, energy requirements, and economic benefit. This present article provides an overview of research studies and advances concerned with the development of nanoparticles and their potential applications in leachate treatment. Nanoparticles can act as antimicrobial and function as reducing agent and catalyst in detoxification of pollutants in the environment, such as organic, inorganic and heavy metals. NPs have been suggested as efficient, cost-effective and environmental friendly alternative to existing treatment materials and presents a number of potential environmental benefits.
