How to operate RO water plant?

Reverse osmosis is a method that uses pressure to force water through a semi-permeable membrane in order to remove the vast majority of pollutants from water. Commercial RO plant manufacturers here we will make an effort to lay out the fundamentals simply so that the reader will walk away with a better grasp of reverse osmosis operation in general and its uses in particular.

Learning about Reverse Osmosis

By pushing water through a semi-permeable reverse osmosis membrane, reverse osmosis, often known as RO, removes a significant amount of dissolved particles and other pollutants from water. For better understanding of Reverse osmosis let us first get to know the osmosis process:


You must first comprehend the naturally occurring process of osmosis in order to comprehend the goal and mechanics of reverse osmosis. Commercial RO plant manufacturers osmosis is a phenomena that happens naturally and is one of the most significant natural processes. A weaker salt solution will transition into a stronger salt solution throughout this phase. Examples of osmosis include the water absorption by plant roots from the earth and by human kidneys from the blood.

A membrane that permits certain atoms or molecules to flow through but not others is said to be semi-permeable. A screen door is an easy illustration. It doesn’t let bugs or anything bigger than the screen door’s openings through, only air molecules. Another illustration is Water vapour can pass through the pores, but liquid water cannot because they are too small.

The reverse process of osmosis is known as reverse osmosis. Osmosis occurs naturally without the need for energy, but in order to reverse the process, energy must be added to the more saline fluid. Water molecules can travel through a semi-permeable membrane called a reverse osmosis membrane.

Operation of an RO plant:

A reverse osmosis plant usually has three to five major phases in action. A semipermeable membrane, a carbon filter, and a sediment filter are all components of a three-stage reverse osmosis system. These correspond to phases 1, 2, and 3, accordingly. To remove particles that the first membrane could have missed, a four-stage system adds a second membrane.

The same sediment filter, carbon filter, and semipermeable membranes are used in a five-stage system. Additionally, it includes post-filtration, which involves passing the water through a second carbon filter to get rid of any remaining contaminants. Remineralization is a phase that some five-stage RO systems include as well. It adds useful minerals back to the cleaned water. The fundamental procedures of a reverse osmosis system are as follows:

  • Prefiltration: To remove bigger particles like silt and chlorine, reverse osmosis systems utilise two different types of prefilters. Dirt, dust, and other impurities are initially removed from the water using a sediment prefilter. The water then continues on through a prefilter made of activated carbon, which binds to and eliminates contaminants including chlorine and volatile organic compounds (VOCs).
  • Reverse osmosis: Reverse osmosis is the primary process that happens after prefiltration. The water is now sent across a semipermeable membrane by the pump, trapping smaller, more difficult-to-remove dissolved solid particles. The bulk of the dissolved particles in the water may frequently be removed during this reverse osmosis process.
  • Drainage: After the water has passed through the semipermeable membrane, the contaminants are eliminated by drainage, which flushes them down. Because impurities can accumulate on the membrane and reduce its efficacy, this step is crucial. The RO system’s efficiency is maintained at a high level by draining the accumulated contaminants.
  • Storage: The treated water is kept in storage until it is used, which is the last step. A pressure tank that is big enough to hold the treated water without creating waste is frequently used as the storage container. A second carbon filter that can catch any stray contaminants may be added after the cleansed water has passed through the first one.
