RO water filtration system is one of the most popular methods of filtration of water. The water pressure pushes tap water through a semipermeable membrane to remove impurities from water. These membranes have tiny pores that help in removing impurities and pass pure water.
There are many advantages of opting for RO purifier systems over others; they are:
- It is simple to operate
- It comes with a modular design for the ease of installation
- It does not require hazardous chemicals
How does the RO water filtration system work?
RO water purification system is a continually working treatment technology. As the name itself suggests, it works by reversing the principle of osmosis, the natural tendency of water to flow through a membrane with dissolved salts from lower to higher salt concentration. You can find this process throughout nature. Plants use it to absorb water from the soil, humans and other animals use it to absorb water from the blood.
How to maintain the RO Water Filtration System?
A top quality Reverse Osmosis water filtration system can last for years if maintained well. Here’s what it takes to keep your system running well for years.
Change Filters Regularly
Be aware of the filter change schedule in your RO system’s owner’s manual. RO systems generally have three, four or five filter stages; yours may have any of them. It is your job to know exactly what filters are present in each stage of your system and pay attention as to when each filter is due for replacement.
Water first flows through a pre-filter to protect the delicate RO membrane. This pre-filter is called sediment filter; it is designed to filter out dirt, silt, sand and other sediments from water. The sediment filter must be changed out every 12 months. In case you fail to change this filter on schedule, dirt, sand and silt can reach the RO membranes making them clogged and foul.
The second filter, i.e. the carbon filter, is designed to remove the chlorine and other taste and odour contaminants that affect the performance and life of the RO membrane. This filter too should generally be replaced every 12 months.
Reverse Osmosis Membrane:
The Reverse Osmosis Membrane is semipermeable and is designed to allow water through by filtering out almost all additional contaminants. If you maintain the previous sediment and carbon filters well, the RO membrane will only need replacement every 2-3 years.
Note: The schedule can vary based on the quality of the water of your house, industry or organisation and its usage.
This fourth stage filter is there to make sure you get the great tasting purified drinking water. It is to polish off the water to remove any remaining taste and odour in the water. It can be changed every 12 months.
How to clean and Sanitise your System?
We would recommend you to clean and sanitise your water purifier system once a year, it could be when you are changing out filters. You can hire a professional to do the job, or you can do it all by yourself.
The steps will help you if you are cleaning your water purifier system yourself. You will want to consult your owner’s manual for specifications on how to clean your system, however here are some general terms that may apply to every RO water plant:
- First, you have to shut off the main valve
- Next, dole out all of the water from your RO faucet
- Remove the sediment filter and carbon filter from their housing
- Keep the filters out, screw the housing back in the place
- Pour 1 cup of hydrogen peroxide into first stage housing
- Reattach all connections
- Turn the main valve on
- Let the system run without the filters; the storage tank will refill rapidly
- Let it run through 2 or more cycles
- Shutt the main valve off again
- Install the new filters
- Allow the tank to fill back up and then drain one or two more times
This process cleanses the RO system and allows it to work well for years to come if you repeat the cleansing process annually.
Can RO Water Filtration System address Hard Water?
Hard water has high mineral content. Hard water is formed when water infiltrates through deposits of limestone, chalk or gypsum that are made up of calcium and magnesium. The more magnesium and calcium in the water, the harder the water.
Now, if you have a high level of water hardness, i.e. high level of presence of calcium and magnesium in your water you may have to consider installing a house water softener since RO cannot address the issue of hard water. The minerals like calcium and magnesium are difficult to remove for an RO system, and it can clog and foul the RO system. Therefore, a water softener can address the water hardness issue prior to the water reaching your RO unit to protect it from damage.
With these tips, you can have your RO system running well for years and longer.
