What is your preference in terms of seawater pretreatment for reverse osmosis membrane desalination?

thanks for information.

Conventional if tight budget. Also consider either UF or as Nikolay mentioned Dissolved air flotation if Algal blooms, high SDI are common place.

In my opinion, it depends on the money that you can afford for the pretreatment, if you want to propose a low cost solution, maybe an usual fitration is enough, with fine or absolut filters, if the budget for this project is high, i recommend using a Ultrafiltration.

The selection will also depend on the quality of the source water. If the source water is experiencing algal blooms most membrane pretreatment systems break algal cells and release easily biodegradable organics which foul not only them but also the downstream RO membranes.
