Hello Anvar,

It is not conservative to consider dual or single media filter as the first pretreatment stage for sea water source containing 100 ppm suspended solids. A flocculation/clarification stage is recommended on upstream. If the source is potential to be attacked be algae bloom, DAF system is needed after coagulation. However, a jar test is recommended before design stage. If the size of plant is large, considering a pilot study is reasonable.

I hope it can help you.
