Seawater Desalination
Seawater desalination has issues that are very different from brackish or wastewater:
- Intake systems need to be designed to avoid entrainment and impingement of sea creatures, plants, and microscopic plankton
- Concentrate discharge mixing is critical to avoid hyper saline plumes, which can harm sedentary sea life.
- Pressures are higher, requiring more energy
- Operating pressure ranges from 800 to 1000 lb/in2
- Seawater is very corrosive.
- Pretreatment system must accommodate periodic algal blooms and high turbidity storm water.
