HSRO Membrane
HSRO Membrane
The HSRO-8040 elements are mainly used in the depth desalination treatment of water in the biomedical field. It is able to withstand the disinfection treatment of hot water at 85 oC, which can fully meet the requirements of making pure water in the important processes, such as raw material production, separation and purification, end product preparation, washing process, cleaning process and disinfection process. The HSRO-8040 elements with ultra low electric charge have many characteristics, such as high fouling resistance, strong ability of recovery after cleaning and so on. The HSRO elements can be widely used in desalination of drinking water, purified water, high purity water and the water for injection.

Important Operation Information:
HSRO element should be handled with thermal stabilization by hot water at first use as follows.
- Under the conditions of low pressure and flow, flushing for 30mins by certainly RO produced water, Max. Pressure＜0.3MPa，and differential pressure between elements is below 0.17MPa.
- Under ultra low pressure, circulating with hot water for 45mins, temperature ≤ 45 oC, Max. Pressure < 0.3MPa, and differential pressure between elements is below 0.17MPa, back pressure is below 0.035MPa
- Adopting the way of circulation by gradually increasing the temperature until it is at 80 oC, heating rate < 3 oC/min. Max. Delivery pressure ≤ 0.3MPa and differential pressure between elements is below 0.17MPa. Back pressure is below 0.035MPa. Finally, making the reverse flow temperature reach to 80 oC, and ensuring the feed water of element inlet max. temperature ≤ 85 oC.
- Keeping the heat over 60mins.
- Adopting the way of circulation by gradually decreasing the temperature to below 45oC, cooling rate < 5 oC/min.
- When the water temperature is determined to be below 45oC, flushing by certainly RO produced water under ultra low pressure. Max. Pressure < 0.3MPa, and differential pressure between elements is below 0.17MPa.
- The thermal stabilization step of HSRO membrane element has been done. Please pay attention to this step should be finished as soon as possible once the RO system starts normally to avoid influencing the performance of element.
