Reverse Osmosis System (RO) :

 

With the rapid improvement in the materials and manufacturing of RO membranes, RO has gained increasing acceptance in the ultrapure water industry over the past decade. Nowadays, RO is the most wildly used technology in the production of ultrapure water.

RO, in combination with other water treatment technologies such Deionization, Electro-deionization, Ultrafiltration, TOC Reduction, Degasification and UV Sterilization has been able meet the requirements of the most demanding user, such as micro-chip and LCD manufacturers with the purest water.


Properly designed RO systems are capable of removing over 99% of ions, bacteria, particles and 98% of organics and silica. Thanks to its high salt rejection, ionic loads of downstream DI systems are greatly reduced. The removal of organics by the RO process also prevents the DI systems from pre-mature organic fouling thus significantly improves their performance and service life

 

Applications:

  • As rough demineralization before DI systems.
  • As a final polishing process before ultrapure water are sent to the points of use.
  • As a water desalination process turning brackish or sea water to potable water.
  • As a water recycling process, e.g., removal of organic and heavy metal from the process water and re-use it.
  • As a precious metal reclamation process, e.g., concentration of the precious metal from the process stream for sales or re-use.

 

Standard Features :

  • PVC SCH 80 piping for RO permeate.
  • Stainless steel piping for RO feed and reject.
  • FRP pressure vessels.
  • Conductivity meter for RO permeate.
  • Permeate and reject rotameters.
  • Pressure gauges for feed, reject and each array.
  • Permeate sampling ports per each pressure vessel.
  • Programmed automatic fast flush before system shut down.
  • High flux and high rejection RO membranes such as Hydranautics and FilmTec.
  • Fully automatic operation.

 

Optional Features :

  • Electronic flow meter
  • Conductivity meter for RO feed and percentage rejection
