Test condition
(A) Feed water pressure 1.55 MPa, Feed water concentration 2,000 mg/L as NaCl, Feed water temperature 25 deg.C, Recovery rate 15%
(B) Feed water pressure 1.03 MPa, Feed water concentration 1,500 mg/L as NaCl, Feed water temperature 25 deg.C, Recovery rate 15%
*1: 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+ salt concentration in brine water)/2)) x 100 [%]
