"HOLLOSEP®" high-pressure type HR/HM Series is an outstanding module that has succeeded first in the world in seawater desalination using a single stage design operated at a high recovery.
The HR Series employs a compact, single element.
The HR Series is especially suitable for a fresh water generator for emergency and fresh water for small vessels since the recovery rate per one element is high, and a compact device can be manufactured.
The HM Series is a double element type that contains two elements inside the pressure vessel.
The HM Series contains elements high in volumetric efficiency in order to reduce the installation volume and makes this unit best suited for an intermediate to super-large seawater desalination plant.
Membrane chemistry based on CTA is compatible with chlorine disinfectant during routine operation and disinfectant can be easily charged for safe storage. These two strong features easily eliminate bio-fouling problems, the greatest concern in seawater desalination.

*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
