Reverse osmosis is a type of water purification system that is used to get rid of impurities in water. It is a straightforward and simple system that doesn’t require a lot of technology or manpower. Purification of water is achieved by putting pressure on water to pass through a semipermeable membrane so that it can remove impurities. This process can be used to get rid of dissolved substances such as salts and other dangerous contaminants like bacteria and fungi.
Impurities Removed By Reverse Osmosis:
Where Do Contaminants Go?
When water passes through the system, the reverse osmosis members and other additional filters, filter out the impurities. The impurities are then flushed down the drain leaving only clean and ready to drink water. Many Reverse Osmosis units have a 4 stage process to ensure that water is pure and clean to drink.
Components Of A Reverse Osmosis System
● Cold Water Line Valve: This is a valve that is fitted on the cold water line valve. It has a tube that connects to the inlet side of the reverse osmosis system pre-filter. It is the prime water source of the reverse osmosis system
● Pre-Filter: Cold water from the valve gets into the reverse osmosis pre-filter first. A system can have more than one pre-filter and it all depends on the preferences of the user. Pre-filter can be a carbon or sediment filter as they are the most popular. The filters protect the reverse osmosis membrane by filtering out sand and other debris from the water.
● Reverse Osmosis Membrane: this is the heart of the system, it contains the semi-permeable membrane that has been designed to remove contaminants. The contaminants are then flushed down the drain to avoid re-contamination. After it has gone through the membranes, the water is stored in a pressurized storage tank.
● Post Filter: when the water leaves the storage tank, it passes through one last filter. The filter is called the post-filter and it is mainly a carbon filter. It is used to remove any unwarranted tastes and odors.
● Automatic Shut Off Valve: this is installed as a way of conserving water. The reverse osmosis system has an automatic shut off valve, it closes when the storage tank is full. When it closes, it stops any water from flowing through the system. When the tank is drained, even a little, the valve opens to let in water flow through the system and fill the tank.
