This is a design model for Multiple-effect distillation with different types of feed configuration. User can select between four types of MED according to the feed flow arrangment. It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto them. Some of the water evaporates, and this steam flows into the tubes of the next stage (effect), heating and evaporating more water. Each stage essentially reuses the energy from the previous stage, with successively lower temperatures and pressures after each one. Additionally, between stages this steam uses some heat to preheat incoming saline water. User can assign the following:
1- Top steam temperature, oC.
2- Inlet feed temperature, oC.
3- Last effect temperature, oC.
4- Performance parameters for the pumps and end condenser unit.
5- Feed and brine salinities ratio.

6- Cost analysis block has been added to the 2nd model version.
