Seawater Desalination Plant
Raw water with a TDS of up to 40.000 ppm serves as a raw water source for the desali- nation plant. For prevention of accumu- lation, suspended solids on the membrane surface the raw water is filtered over a fine filter. This pretreatment measure guarantees that no solids interfere with the desalination process.
Reverse osmoses is a reliable technology for desalination. Therefore the required intake water quality to the reverse osmoses is essential. It is known that, most of the operation problems of an reverse osmoses system is linked with poor quality of intake water to the reverse osmoses.
It ́s very important to take proper pretreat- ment technology in order to optimize the lifetime of membrane, chemical dosing duration, operation cost, project construc- tion space, project capital investment, and so on. Therefore, an efficient pretreatment has to be established by the client to guarantee the system running.
The desalination equipment is installed in one container, which is completely prefabri- cated.
