WHAT IS A DESALINATION PLANT?
A desalination plant converts salt water into potable water. Reverse osmosis is the most often used method for the process, which involves applying external pressure to force solvents through a membrane from a high-solute concentration portion to a low-solute concentration area. The membranes’ small holes allow water molecules to pass through while leaving salt and most other contaminants behind, resulting in clean water being released on the other side. The majority of these plants are located in places with access to sea water.
OPERATION PROCESS
The plant uses reverse osmosis (RO) technology to desalinate sea water, which contains up to 6.4 ppm aluminium and 50 NTU of turbidity. By recovering kinetic energy from the brine solution and transferring it to the desalinated water that has gone through the osmotic membrane, energy recovery units help to improve the system’s efficiency.
Coagulation-flocculation, gravity, and pressure filtration are all used to pre-treat raw sea water. The filtered water is then pumped to the facility, where it is subjected to a series of pre-treatments before passing through the RO trains. The water is then pumped at high pressure through the RO membranes.
