"HOLLOSEP®" low- & intermediate-pressure type HA Series is best suited for the ultra-pure water making apparatus for the electronic industry and de-mineralized water making equipment for the hospital and medical industry.
This series employs a single element type excellent in compactness. This type is provided with the supply water and concentrated water inlets on one end and the permeate water outlet on the other end. The hollow fiber type reverse osmosis membrane is high in volumetric efficiency and can be contained in a compact pressure vessel, thereby saving space as far as possible.
The design and materials of construction is such that the contact of permeable water with the member is minimum and makes it possible to obtain high-quality permeable water.
By adopting cellulose triacetate chemistry for the membrane high chlorine resistance is achieved and excellent performance of "HOLLOSEP®" is available for a wide range of applications.

*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 L : 0.98MPa,500mg/L NaCl,25 deg.C and 30%Recovery
