What is Reverse Osmosis?

Reverse Osmosis is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane. To understand the purpose and process of Reverse Osmosis you must first understand the naturally occurring process of Osmosis.


Osmosis

Osmosis is a naturally occurring phenomenon and one of the most important processes in nature. It is a process where a weaker saline solution will tend to migrate to a strong saline solution. Examples of osmosis are when plant roots absorb water from the soil and our kidneys absorb water from our blood.


Reverse Osmosis

A semi-permeable membrane is a membrane that will allow some atoms or molecules to pass but not others. A simple example is a screen door. It allows air molecules to pass through but not pests or anything larger than the holes in the screen door.

Reverse Osmosis is the process of Osmosis in reverse. Whereas Osmosis occurs naturally without energy required, to reverse the process of osmosis you need to apply energy to the more saline solution. A reverse osmosis membrane is a semi-permeable membrane that allows the passage of water molecules but not the majority of dissolved salts, organics, bacteria and pyrogens. However, you need to ‘push‘ the water through the reverse osmosis membrane by applying pressure that is greater than the naturally occurring osmotic pressure in order to desalinate (demineralize or deionize) water in the process, allowing pure water through while holding back a majority of contaminants.





Equipment Introduction

A complete one stage RO equipment consists of pre-treatment system, RO host and control system.

Pretreatment system is normally composed of quartz sand filter, activated carbon filter, soften filter and precision filter. The mainly working purpose is to protect the following RO membrane by separating large particle pollutants such as sediments, colloid, suspended solids, 
pesticides, especially residual chlorne and organism from the raw water. And softening equipment is needed to protect the following RO membrane from scaling and block if the raw water is of high Ca2+ or Mg2+ ion content.


RO host is the key part of the whole system as it determines the output water quality. It mainly consists of booster pumps, membrane shell, RO membrane, control circuit and so on. The salinity filtering ability of a single piece of RO membrane can be above 99% and conductivity of one stage RO output water within 10μs/cm(25
) if with reasonable design. So the design reasonability will directly determine the cost-effective and operating performance of the system. And power-saving, operating pressure, desalination rate, saltness of output water and receovery rate should be taken into consideration during design process.

The pre-treated water must not come into the RO system unless the SDI is less than 4. And after RO processing, pure water(desalted water) will come into the storage tank and concentrate water will be discharged.
