Reverse osmosis System in Pakistan
What is Reverse Osmosis?
A water treatment process that removes undesirable materials from water by using pressure to force the water molecules through a semipermeable membrane. This process is called reverse osmosis because the pressure forces the water to flow in the reverse direction (from the concentrated solution to the dilute solution) to the flow direction (from the dilute to the concentrated) in the process of natural osmosis.
What does a Reverse Osmosis Water Filter Remove?
Reverse osmosis water filtration systems can remove 90% of total dissolved solids (TDS) from water and can provide the purest water available for your home. RO water filters remove a wide range of contaminants and minerals from your drinking water, including sand, chlorine, fluoride, cryptosporidium, and hexavalent chromium.
Producing Drinking Water Using Reverse Osmosis
Although Reverse Osmosis seems like a complex system it is really a simple and straightforward water filtration process. And it’s not a new process. High-pressure (pump driven) reverse osmosis systems have been used for years to desalinate* water – to convert brackish or seawater to drinking water. Having a better understanding of how a reverse osmosis system works will eliminate the mystery and confusion you may feel when you look at a reverse osmosis system with its many-colored tubes and multitude of filters. Read on to enhance your knowledge of residential reverse osmosis systems.
The most important points to remember:
- All RO Systems work the same way.
- Most RO (Reverse Osmosis) systems look alike.
- All RO Systems have the same basic components.
- The real difference is the quality of the filters and membranes inside the RO.

How the Reverse Osmosis System Works?
Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. These impurities and contaminates are flushed down the drain.
Ultimately, the factors that affect the performance of a Reverse Osmosis System are:
- Incoming water pressure
- Water Temperature
- Type and number of total dissolved solids (TDS) in the tap water
- The quality of the filters and membranes used in the RO System (see operating specs)
