Note:
(1) The parameters listed are measured after 30 minutes of stable system operation;
(2) Water production rate has a deviation range of ±15%;
(3) Chemical cleaning recommended at temperatures ≤30°C, above which cleaning solution pH shall not exceed 2.0-12.0;
(4) In multi-element housings, the maximum pressure drop from inlet to outlet should be controlled within 0.25MPa, not exceeding 0.3MPa in extreme cases;
(5) RBW-HR and RBW-LE may also use the 440 high-flow and 4040 commercial membrane elements.
The data presented herein have been tested and are reliable, but variability may occur due to different testing methods and operating conditions.
