Spacer Tube RO/NF STRO / STNF
STRO/STNF Membrane Introduction
With the development of membrane technology industry, there are differentiated requirements to the performance of the membrane products, such as lower feed quality requirements, higher pressure to improve concentration ratio, longer cleaning cycle and service life. As a result, the open channel type with high pressure membrane arises at the historic moment.
> Used for sea water desalination and waste water treatment.
> Spacer tube (ST) module is high strength design, from 70bar up to 120 bar operating pressure.
> Open feed spacer with low flow resistance and concentration polarization.
> Spiral wound structure with more membrane area.
Features
High strength design, up to 120 bar operating pressure
Open feed spacer with low flow resistance and concentration polarization
Spiral wound structure with more membrane area
More options for feed spacer
Applications
Industrial wastewater
High salts wastewater
Spiral wound RO/NF concentrates
Open feed spacers
STRO/STNF module
STRO/STNF membrane
High pressure vessel
SUS center link
Inlet and outlet pipe and accessories
Comparison of STRO/STNF Membrane and conventional RO/NF Membrane
Identical
High membrane area
Integrated design
Cross flow filtration
Difference
SUS center link with high strength and stability
Uniform internal water distribution structure
Reduced impact of the membrane module flow, higher cross-flow
Open feed channel

Salt seal installed on the end of the flow, low pressure side / permeate side.
Stable flux, salt rejection based on the following test conditions:
RO1: 2000mg/l NaCl , pressure 15.5bar, recycle rate 15% , temperature 25℃, pH=8.
RO5:32,000 mg/l NaCl , pressure 55bar, recycle rate 8%, temperature 25℃, pH=8.
NF2:2000 mg/l MgSO4, pressure 7barr, recycle rate 15% , temperature 25℃, pH=8.
Note: We can provide any flat sheet membrane to make ST module, for example: STRO4-8035, STRO5-8035, STRO1-8042, STNF1-8042, etc.
