What is Reverse Osmosis in RO Water Plant?

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. In addition, to removing contaminants and sediments, reverse osmosis can also remove microorganisms – which you certainly do not want to drink. Hence, it gets water clean down to a molecular level, leaving only pure H2O behind.

How Does Reverse Osmosis Work in RO Water Plant?

Before we go into the details of how reverse osmosis works, we should start by explaining how osmosis works. As you may remember from your high school chemistry class, osmosis is the process by which water passes through a semi-permeable membrane (RO Membrane) from a less concentrated solution into a more concentrated one. In other words, the pure water passes through the filter to the contaminated water in order to equalize the concentrations – which is not what we want our drinking water to do. So, this movement generates osmotic pressure.

First of all, in reverse osmosis, an applied pressure is used to overcome the osmotic pressure and push the water from high concentration of contaminants to low concentration of contaminants. So, this means it’s being forced in reverse and the contaminated water is trying to move into the pure water, but because it must pass through a filter first, the contaminants get trapped and only the pure water passes through; resulting in the cleanest possible drinking water – which is exactly what we want!

Why is Reverse Osmosis Beneficial?

Reverse osmosis differs from carbon filtration in that it can rid the water of up to 99.9% of all contaminants and sediments, or particles as small as 0.001 micron, whereas carbon filtration can only remove particles as small as 1 micron accordingly. So, your local tap water could be award-worthy clean when it leaves the municipal plant but as it travels miles from the plant to your glass it could pick up a host of contaminants or it may have a naturally high number of total dissolved solids (TDS) in the water, so it would be best to get a reverse osmosis filtration system to safeguard that your water is contaminant-free.

Factors Affecting RO Water Plant and Process Performance

The performance of a RO system depends on factors such as membrane type, flow control, feed water quality, temperature and pressure accordingly.

Also, only part of the water entering the unit is useable, this is called the % recovery. This is affected by the factors listed above.

For example, the amount of treated water produced can decrease by about 1-2% for every 1 degree Celsius below the optimum temperature.

So, systems must be well maintained to ensure good performance with any fouling requiring cleaning maximizing the output of water.

Meanwhile, Anti-scallant and Anti-fouling chemicals may be needed, and the choice of biocide would depend on the membrane type, alternatively, other filters may be required to remove chlorine from water to protect the life of the membranes.

Finally, a good treatment regime is needed and knowledge of the specific foulants so the optimum cleaning and maintenance chemicals can be chosen for RO Water Plant.

Reverse Osmosis in Desalination

In the late 1960s, reverse osmosis (RO) was developed for desalting saline water supplies. So, this process is based on the principal of osmosis and requires a membrane barrier to separate salts from water. Because reverse osmosis technology required considerably less energy to operate than distillation, so, it was considered to be the technology that would make desalination much more attainable to the world’s water scarce areas. Indeed, RO for water purification has become widely utilized not just for drinking water applications but for high purity industrial process applications such as manufacturing of electronic components, pharmaceuticals, chemicals, boiler feedwater, medical applications and industrial and municipal wastewater recovery systems as well.

RO Water Plant in Desalination

However, in the early days of RO commercialization, historical design and operations information was not available and, as with any new technology, many problems arose. Therefore, in the initial years of RO membrane plant or RO Water Plant application, many owners and operators experienced costly downtime attributable to lack of applications experience by engineers, vendors, etc. As both membranes and applications engineering became more advanced with time, RO systems were installed and operated with greater success. So, today, with the necessary understanding of feedwater source conditions, pretreatment needs and high-quality system engineering, Reverse Osmosis can be applied to almost any ground or surface water desalination/purification application. Hence, advancements in membrane manufacturing and applications engineering have made RO water plant the leading process in the worldwide water desalination market.

Meanwhile, the definition of desalination generally is considered to be the production of fresh water from salt water or seawater. However, the term also is commonly used by engineers to describe desalting of slightly to moderately saline waters normally referred to as brackish. For the remainder of this discussion, we will focus on desalination as defined by seawater desalting.
