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 0.25 MPa, not exceeding 0.3 MPa in extreme cases;
The data presented herein are derived from specific tests and are true and reliable. However, differences may exist between test conditions and actual application environments, so actual results may vary. It is recommended that users verify and adjust according to their specific operating conditions and assume relevant responsibilities themselves.
Applications
Shuiyi Cyclean™ Enhanced RO Membranes are widely used in challenging wastewater reuse applications across the steel, coal chemical and petrochemical industries due to their rugged and stable performance.
