Industrial RO Membrane
RT-2540HF
1. Product Spec
HF, HR series are Industrial grade polyamide composite membranes, they are suitable for salt rejection treatment of surface water, groundwater, tap water and municipal water. Features of HF and HR series membrane are low-pressure operation, high water production and good performance of salt-rejection.
HF and HR series membrane mainly used for industrial water supply systems, including all kinds of sizes of industry pure water supply, power plants, and boiler feed water etc. They can also be used for treatment of brackish water such as wastewater of high concentration of salt, or wastewater of drink water manufacturing industry, etc. In addition, it has a very high performance of removing soluble salts, especially suitable for the preparation of supreme-pure water for electronic, electrical industry.
SW series of membrane are design for treatment of seawater and high concentration brackish water. It can be used for desalination of seawater and high concentration brackish water; Various industrial water treatment, such as power plants, boiler feed water, etc. It can also be used for wastewater re-use or variety of high value-added matter condensed and recycling applications, e.g. food and drugs industry.

3.Related Information
①For the recommended design range, if the user did not strictly follow the operating conditions provided by us, we will not bear all the consequences arising therefrom.
② The produced water amount listed in the table is an average value, compare with the standard value, the difference of the minimum amount of water produced by a single membrane does not exceed ± 15%.
③ All wet membrane undergo rigorous factory inspection, and use specific protective solution and vacuum-packed, then stored in strong cartons. In order to prevent growth of microorganisms during short-term storage, transport and the system standby, we recommend preparation protective solution by RO membrane produced water, then immerse membrane.
④ When new membranes run, the produced water of at least the first hour has to be discharged out.
