Seaflex
The core of the Seaflex membrane technology is the hydrophilic hollow membrane, composed of a PES/PVP blend. The membranes’ high mechanical and chemical strength makes them extremely durable. The membrane modules are operated inside-out and have proven to be first choice in the pretreatment for sea water reverse osmosis systems (SWRO). By thoroughly removing suspended solids, Seaflex membrane modules protect downstream SWRO systems from fouling.

Features
- Removal of microorganisms
- High membrane packing density: The industry’s smallest free volume in a membrane module
- 100% integrity testing on individual fibers
- Individual fiber repair
- Very good antifouling behavior
- Typical permeate quality:
- SDI < 3
- Turbidity < 0.1NTU
- Excellent chemical resistance with a wide pH range (2 – 12) and high chlorine stability (maximum free chlorine 500 mg/l)
- Typical high permeability: low energy consumption
Functional Description
Seaflex for SWRO pretreatment
The core of the Seaflex membrane technology is the single-fiber, inside-out filtration process that delivers a robust solution. The modules are operated vertically and can be configured in three different ways:
- In the X-line rack
- With standard end caps
- In the vertical high pressure setting
