Water Desalination

Vincent D. Reynolds, MBA, PE

The earth’s surface is replete with water with the majority of this water located in our oceans. The water in our oceans (seawater) has a salinity of approximately 3.4% and is not considered potable for human consumption in large quantities. In order to make seawater fit for human consumption it has be desalinized. Water desalination is used to remove salt and other solids from brackish and seawater to produce potable water supplies. Several variables are involved in deciding the most suitable location for a water desalination plant as well as which type of desalination will be utilized.

This course will discuss the various desalination processes including various chemical and mechanical pretreatment and post treatment processes that are used to make the water safe and pleasant to drink. Maintenance and disposal issues associated with the different types of desalination processes will be discussed. Design examples will be presented to aid in understanding the course material.

The student will be directed to study the document “Water Desalination,” published by the army corps of engineers which also serves as a document for the Unified Facilities Criteria (UFC).

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
