ABSTRACT
The increased world population and industrialization has caused a surge in the rise of the concentration of pollutants in water resources, which is a rising concern as it poses a serious threat to both aquatic and human health. With limited resources, the emergence of new technologies facilitates the reuse of polluted water for targeted applications before it brings out any problems to the eco-system. Cold plasma is one of the effective oxidative techniques, which is proven to be effective against most pollutants as it contains reactive species, UV components. The effectiveness of treatment varies based on the plasma type, gas composition, power, temperature, and treatment chamber geometry. Hence, it becomes necessary to forecast the treatment outputs with known parameters under a feasible limit to set-up the actual process condition for practical applications. With the kind of growth computational fluid dynamics (CFD) possess in plasma technology, any geometrical (1D, 2D, and 3D) model can be stimulated to study its nature and interaction with the pollutant. As plasma is modeled in a fluidic/kinetic macroscopic approach in CFD, the simulation process can be termed as computational plasma dynamics (CPD). This chapter discusses the plasma modeling approaches for water treatment systems with their result interpretations to understand modeling and its significance.
