Seawater entering the desalination plant goes through spin down screens filter to remove suspended solids and debris, then gets injected with oxidants and coagulators to purify sea water as in many parts of the world waste water is dumped into the sea, leading to the contamination of seawater. In this process, chemicals are added to the seawater to make algae, organic materials and particles bond together so they can be removed more easily in the filtration stage that follows.
In the next stage, seawater goes through automatic backwash Sand Filters to catch all the suspended solids, algae and organic materials that has bonded together.
Then Seawater goes through Automatic Backwash Activated Carbon Filters to reduce color and smell, as well adjust pH level of seawater.
Finally the seawater goes through a series of 5 micron Sediment Filters to remove silt and fine particles that may be remaining after the pretreatment process.
