Product Description

We are a renowned manufacturer of the best quality Spiral Wound RO Membrane. Extensively used in wastewater treatment applications, it is a submerged backwashable spiral membrane. This membrane implements washing flow from the permeate carrier side with certain pressure. In addition, this Spiral Wound RO Membrane is also used in RO pre- treatment, landfill leachate pre- treatment and recycled water. We offer these membranes to clients in different specifications at competitive prices.

Features:

  • Allows frequent back-washing
  • Minimizes the deposition of pollutants on membrane surface
  • Durable quality

  • Salt seal installed on the end of the flow, low pressure side / permeate side.

  • Stable flux, salt rejection based on the following test conditions: RO: 32,000 mg/l NaCI, pressure 55bar, recycle rate 8%,temperature 20°C
  • pH=8. NF: 30,000 mg/I MgSO4 , pressure 45bar,recycle rate 8%,temperature 20°C ,pH=8.
  • There will be a minor difference of permeate due to the feed quality.
