XLP (Extra Low Pressure) series is an extremely low-pressure aromatic polyamide composite membrane element developed by Hangzhou E-MEM Environmental Technology Co., Ltd for surface water and groundwater desalination, which can achieve the same high-water flux and high desalination rate as the conventional low-pressure film under the condition of very low operating Pressure. Its operating pressure is about 1/2 of the operating pressure of conventional low-pressure composite membrane, so as to reduce the investment cost of related pumps, pipelines, containers, and other equipment and the operating cost of reverse osmosis system, and improve economic benefits.
XLP series membrane elements are suitable for the treatment of low-salt water sources with not high requirements for desalination rate, such as surface water, groundwater, tap water, and municipal water with salt content less than 1000ppm. Mainly used in various scales of pure water, boiler feed water, food processing, and other fields.

Matters Needing Attention
- The data and information provided by Hangzhou-MEM Environmental Technology Co., Ltd in this sample are all obtained through long-term experiments, and we are convinced that these data and information are accurate and effective. Customers are requested to use the product in strict accordance with the design, use, and maintenance requirements of the product and keep relevant data records. Hangzhou E-MEM Environmental Technology Co., Ltd shall not bear any consequences arising from customers’ failure to use and maintain the products in accordance with the conditions provided by this sample.
- The permeate flow listed in the table is the average value, and the deviation of a single membrane element of permeate flow is±15%.
- Before products leaving the factory, the dry membrane element has no protective liquid, while the wet membrane element is stored and treated with 1.0% sodium bisulfite (10% glycerin antifreeze added in winter) solution and vacuum-packed.
- Dry membrane elements should always be kept wet after wetting. When wet membrane element is not used for a long time, in order to prevent the growth of microorganisms, it is recommended to soak the membrane element with protective liquid containing 1.0% sodium bisulfite (food grade)(prepared with RO production water).
- For initial use of membrane elements, it is recommended to flush first at low pressure for 15-25 minutes and then at high pressure for 60-90 minutes (water production not less than 50% of the system design).All production and concentrated water shall be discharged within the first hour of membrane element operation.
- It is prohibited to add any chemical agent that has an impact on the membrane element in storage and operation. If such chemical agent is violated, Hangzhou E-MEM Environmental Technology Co., Ltd will not bear all the consequences arising therefrom.
