Open intakes are located above the seafloor and are the most common type of intakefor large (> mgd, or >, m3/d, production) plantsSeabed intakes are buried pipes and/or wells dug beneath the shoreline or oceanfloor, The subsurface geology typically limits capacity and performance Seawater intake wells have proven to be quite economical for desalination plants with acapacity smaller than mgd (production)
Seabed for decreasing pollution and therefore decrease the treatment phase
Intake facilities for seawater desalination project are basically classified into the above three types, including beach well intake, subsurface water intake and open sea water intake. Good-quality raw water can be delivered by beach well intake, thereby it reduces investment and the operating cost of the pre-treatment equipment, nevertheless it should be taken marine geological structure, hydrology water quality and water quality unstable factors when operating into consideration, and confirmed after looking into in-depth investigation. Subsurface water intake is capable of delivering quite good water, but this kind of intake is probably less adopted because of its large investment and complicated construction. Open sea water intake-a kind of more popular intake method, can be used for different seawater desalination projects.
Open Intakes are more suitables for large plants.
the best for intake seawater system is Seabed!
Seabed in order to minimise the pretreatment phase
