The Mathematical Model

Abstract The mathematical model of postproduction suspension concentration by microfiltration has been developed. This model describes a process conducted in a batch system with membrane washing by reverse flow of permeate. The model considerations concern filtration pseudocycles consisting of the filtration period and the membrane washing period. The balances of continuous phase volume, dispersed phase mass and energy, for each period of pseudocycle respectively, have been presented.

Life On Earth

The planet Earth has an abundant supply of saline water but it requires special treatment to ensure the supply of potable water to sustain life on Earth. Water desalination can be used to achieve this objective. In order to understand this process, research was undertaken on water desalination with a focus on reverse osmosis (RO) in order to develop a simple mathematical model of this process. Mathematical modelling can be used to describe, explain and calculate the solvent and solute fluxes through RO membranes. Such techniques are commonly used by membrane manufacturers to develop proprietary software to study their product’s performance. Two such software packages were used to study the effects of the operating conditions on the performance of RO membrane. Good agreement was achieved between the salt rejection results of the mathematical model and the computer software.
