Water Desalination and Purification Technology Training
Water Desalination and Purification Technology Training covers many aspects of water supply challenges facing the World, and areas of water desalination and purification technologies that may lead to technological solutions to these challenges.
Having access to drinking water is a global problem. In the US, California, Nevada, New Mexico and other desert states are facing sever drought, which makes drinking water scarce and precious. The situation is no better in other countries located in desert areas of the glob such as some parts of Middle East or Africa. Overall, more than 1 billion people in the world do not have access to clean potable water.
Water desalination technology converts the un-drinkable brackish water or seawater into drinkable water. However, it has to be done with minimum cost and energy use in order to be feasible and sustainable.
The water desalination and purification training course is designed to give you sufficient knowledge about desalination and filtration processes. It also teaches you the fundamental thermodynamics and transfer phenomena, which govern the production of water out of brackish or seawater.
The water desalination and purification training course discusses the characteristics of the seawater and brackish water. The course introduces you to thermal technologies, nano-filtration, osmosis, reverse-osmosis, electrodialysis, distillation, and desalination processes.
The water desalination and purification training course also discusses the associated costs of desalination and gives you a good perspective about the techniques and strategies could be applied to reduce the costs.
To sum up, the water desalination and purification training course gives you a good understanding in scientific, engineering, and management aspects of desalination, from the chemistry of water to the process and cost analysis of water purification.
The water desalination and purification training course is suitable for all the individuals willing to gain more detailed understanding of how desalination works and what is the science behind it. It also is useful for the developers and contractors looking for new methods in order to make the existing desalination plants sustainable and cost effective.
