If you are looking for a professional ro membrane manufacturer in China, then Shanghai CM can be your first choice. CM has been an expert ro membanes supplier in China since 2009. We can provide you turn key water treatment solutions.
Compared to traditional filtration technologies that rely on a screen or filter to remove particles, reverse osmosis (RO) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration.
Reverse osmosis water treatment provides the finest level of filtration. The RO membrane acts as a barrier to all salts and inorganic molecules, as well as organic molecules with a molecular weight greater than approximately 100. It is therefore a highly effective process for removing contaminants such as:
Professional reverse osmosis membrane solutions for various water treatment applications, from brackish water to ultra-low pressure systems
Brackish water RO membranes are used to treat brackish water, which is water with a TDS level between 1,000 and 10,000 ppm. Brackish water RO membranes are designed to function at pressures over 200 psi and require more energy than tap water RO membranes. The primary difference between brackish water and seawater is the amount of dissolved salts and solids.

The low-pressure (LP) series is an aromatic polyamide composite membrane element used for desalination of medium and low concentration brackish water. It has the characteristics of high desalination rate and large flux. It can be widely used in municipal water supply, surface water reuse, coal chemical industry, thermal power generation boiler supply water, food industry water, textile printing and dyeing, electroplating industry and other fields.

The ultra-low (ULP) pressure series optimizes the membrane manufacturing process and has higher water flux and salt rejection rate than the previous generation, as well as better pollution resistance. This membrane element is suitable for desalination and deep treatment of low-salt raw water such as surface water, underground water, tap water, etc. with a salt content of less than 1000ppm. It can achieve high water production under extremely low operating pressure or small membrane area.
