Products >> Reverse_osmosis_RO_system seawater desalination system
Membrane desalination equipment is a process in which seawater enters the low-pressure side of the membrane through a semi-permeable spiral wound membrane under pressure, and excess salt and minerals in the water are blocked on the high-pressure side and removed with concentrated seawater to obtain fresh water.

Process flow
Sea water → lifting pump → flocculation sedimentation storage tank → raw water booster pump → quartz sand filter → activated carbon filter → primary security filter → precision filter → sea water desalination high pressure pump → sea water desalination reverse osmosis device product water tank → water supply pump
System Supply List
1. Reverse osmosis membrane: adopts American Hydra, Dow or GE seawater membrane
2. Membrane shell: FRP material
3. High pressure pump: Danfoss super duplex steel
4. Energy recovery device: Danfoss super duplex steel or ERI
5. Frame: carbon steel spray paint epoxy zinc-rich primer, intermediate paint, polyurethane top paint 250μm
6. Piping: the high-pressure side pipeline adopts duplex steel or stainless steel pipeline and high-pressure hose, and the low-pressure side pipeline adopts UPVC pipeline
