Description:
FR series products are aromatic polyamide reverse osmosis membrane
element with anti-foulingproperty used in complex influent
condition.
This series membrane adopts special processtechnology to improve
the hydrophilicity, charge characteristic and surface smoothness,
andreduces the growth and adsorption of pollutants and surface
microorganisms in products running.
FR membrane element adopts 34mil wide channel spacer for easy
cleaning, and also helps toreduce fouling and pressure difference
of membrane system and maintain a longer lifespan.
It mainly used for reclaimed water, reused water, waste water,
reverse osmosis concentrated watertreatment, etc.within
salinity<10000mg/L.
The application fields include electricity, metallurgy,
steel,chemical industry, textile and dyeing, municipal sewage etc.
lt has the characteristics of high-desalination, good restorative
after cleaning and low pressure drop (the pressure gap between
thefeedwater and concentrated water ).
Applications:.
● Production wastewater treatment, reclaimed water recycle,sewage
wastewater treatment etc
● Industrial applications for power, steel,
electroplating.petrochemical, coal chemical industry, textile and
dyeing, pulp &papermaking,landfill leachate etc.
● FeedTDS below 10000mg/L
