Reverse Osmosis Membrane (RO)

Purifying water through pressure-driven separation.

Proven, reliable, high-performance water purification

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:

In normal operation, the membrane surface in RO elements can become fouled by mineral scale, biological matter, colloidal particles and insoluble organic constituents. Deposits build up on the membrane surfaces during operation until they cause loss in normalized permeate flow and/or loss of normalized salt rejection.
Elements should be cleaned whenever any of the following conditions occur:

· the normalized permeate flow drops by >=10%
· the normalized salt passage increases by >=10%
· the normalized differential pressure (feed pressure minus concentrate pressure) increases by >= 15% from the reference condition established during the first 48 h of operation.

If cleaning is delayed, system performance recovery may be less effective.  

To improve the efficiency of reverse osmosis systems, methods such as optimizing pre-treatment processes to reduce suspended matter and particle content in the source water and minimize membrane fouling; adjusting operational parameters like pressure, flow rate, and temperature to achieve optimal filtration results; regularly cleaning and replacing filters and membrane elements to keep the equipment in good condition; and selecting high-performance reverse osmosis membrane materials to enhance membrane permeability and anti-fouling capabilities can be adopted.

The service life of a reverse osmosis membrane depends on several factors, including water quality, pressure, temperature, and usage frequency. Generally speaking, the lifespan of residential reverse osmosis membranes is about 3-5 years, while industrial membranes may require more frequent replacement and maintenance.

Reverse osmosis systems need regular filter replacement and membrane element cleaning to maintain their good filtration performance. Additionally, it is important to ensure that the system’s pressure and flow are within the design requirements to avoid damage due to improper operation.
