"HOLLOSEP®" high-pressure type HB Series and HJ are based on a hollow fiber configuration module that builds on the proven reliability of conventional Our RO module using cross-wound arrangement of CTA hollow fiber.
The outer diameter of the hollow fiber is reduced and this allows a greater pressure resistance and a higher packing density that leads to increase in membrane area/unit volume as compared with conventional fiber dimension and allows greater production of water. Improved pressure resistance allows the modules to operate at higher recovery condition for seawater desalination.
HJ and one of HB Series(HB10255FI) also builds on a new technology based on both open-ended(B.O.E.) hollow fiber structure vs. single open-ended hollow fiber structure. The both open-ended hollow fiber membrane structure allows reduction of pressure drop along hollow fiber bore that leads to greater product water flow.
HB9155 element and HJ9155 module are specially designed for the replacement of the DuPont B10-Model series. Their high chlorine tolerance provides excellent resistance to fouling matter and allows easy control and maintenance in operation.

*1:
The product flow rate and the salt rejection indicate values obtained under the test conditions two hours after putting the module into initial operation.
*2:
The salt rejection defines the product quality and is indicated in the following formula.
(1 - salt concentration in product water / salt concentration in feed water) x 100[%]
  Test Conditions : 5.39MPa,35,000mg/L NaCl,25 deg.C and 30% Recovery
   
 
  "HOLLOSEP®" HB10255 and HB10255FI is provided with 2 hollow fiber type elements in the pressure vessel similar to HM series. Since product water of each RO element in the module can be taken to measure the conductivity, both operation and control are also easy.
   
  Dupont B10 Compatibility
   
  The HB9155 element and HJ9155 module are specially designed for the replacement of the DuPont B10-Model series. Especially, the HB9155 element is a "drop-in" replacement for the Dupont single element pressure vessels,DuPont,Models 6840TA and 6845T.
The HJ9155 module is the same length and port design as the DuPont,Model 6880T B10-Twin.
In addition, the both HB9155 and HJ9155 have excellent chlorine tolerance similar to the conventional "HOLLOSEP®" modules. This unique tolerance allows effective chlorine injection into the RO module as the most superior disinfectant to prevent biofouling. Then, it enable RO module operation to be stable easily.
