Abstract

In this paper, we solve the water purification equation in a reverse osmosis system of salt water. We shall predict the concentration of salt solution at a given position and time in the process of reverse osmosis. We use the two-dimensional advection-diffusion equation as the governing equation, which is a partial differential equation. The partial differential equation is converted into ordinary differential equations with a transformation method. Furthermore, in searching for solutions, an analytical approach is used. This approach is successful in computing the concentration of salt in the reverse osmosis process.

Keywords: : advection-diffusion equation reverse osmosis water distillation
