Modeling the desalination of saline water by using bacteria and marsh plants Original Research Article

On the planet earth, large amount of saline water (in seas and some lakes) is present and a concerted effort is needed to desalinate this water by using cheaper methods already existing in nature. Keeping this in view, a non-linear model for desalination of saline water is proposed and analyzed by using bacteria (halophiles) and marsh plants (salt grass). The system is assumed to be governed by four dependent variables namely the salt concentration, the density of halophile bacteria, the biomass density of marsh plants and the concentration of dissolved oxygen. The density of halophiles and biomass density of marsh plants are assumed to follow logistic models and their growth rates and carrying capacities increase due to interactions with salt in water.
