Seawater treatment

Sulzer’s pumps achieve this by delivering sea water to the SRU / SWRO membrane racks. The configuration of the sea water treatment module will determine which pump type is selected. While BB2 pumps are usually designated for this application, multistage BB3 and BB5 pumps are selected if the membrane requires a higher pressure.
