Wuxi Ewater Water Treatment Co., Ltd.

Industrial reverse osmosis membrane is the core component of industrial water treatment and membrane separation, used to achieve separation of water quality levels through pressure-driven movement, widely used in pure water preparation, seawater desalination, and brackish water reuse.
Industrial reverse osmosis membrane is a type of human-made composite membrane, under high osmotic pressure, selectivity allows water molecules to pass through, retaining dissolved salts, colloids, organics, microorganisms, etc., achieving water purification, desalination, and concentration.
With the pressure difference as the driving force, reverse osmosis is performed naturally; relying on desalination - expansion and electric field gradient realization high-efficiency separation, and non-single pure substance separation. The membrane surface layer has a thickness of approximately 0.1 nm, accurately retaining dissolved salts and small molecules.

Main flow for the aromatic family concentrated membrane, three-layer structure:
Ultra-thin retention layer: determining desalination and throughput
Multiple support layers: ensuring permeability
Non-woven base: providing mechanical strength

Key performance
Desalination rate: Hardness water membrane **≥99.5%, seawater desalination membrane ≥99.8%**
Applicable pH: 2-11, stable chemical cleaning
Operating pressure: Hardness water 1.0-3.0 MPa, seawater 5.5-8.0 MPa
Features: High flow rate, high retention, stable operation, long service life.
