RO Water Purifier – Reason Why You Buy Reverse Osmosis
Reverse Osmosis is a very popular way of water purification. There is a semi-permeable membrane with this system. The main task of the membrane is to remove bigger particles, ions, and molecules from water.
External pressure is used to remove particles from water. Pour solvent is stored on the one side of the membrane. On the other side of the membrane, pollutants become stored up.
The system ensures drinkable water by removing pollutants from water. The membrane can’t remove ions and big molecules from water. It can easily pass the smaller molecule through the membrane easily.
In normal Reverse Osmosis system, the solvent moves from low solute concentration from high solute concentration by a membrane.
Here reduction of free energy is working as a driving force. Apply an outer pressure for the normal flow of the RO system.
The method is same as the other membrane technology applications. The predominant gives up the system is size exclusion or straining. Therefore the system gets top efficiency for the concentration and solution’s pressure.
Reverse Osmosis makes the system dependent on force, flow rate and other situations. It involves diffusion also. The system is a very popular water purifier system for all people. It purifies water from the sea, removes the salt and other sewage materials from water molecules.
How Reverse Osmosis Filtration Works
At the time of using the RO system, you need to follow some processes to purify drinking water.
When you look at an RO system, you will notice 3 cylindrical canisters on a manifold. Among them on is the membrane and other two are carbon filters. Now let us closely notice what every one of those cartridges does.
Step 1: Pre-filtration
The 1st step of purifying water of the RO is meant to save the membrane. It eliminates big sediments and aids to remove chlorine.
The first cartridge is known as the carbon block filter and the sediment filter. It conserves the membrane that gets clogged by more sediment. The membrane may damage by exposing more chlorine. Chlorine is normally found in municipal water.
If you begin with water, you will get the excellent performance of the RO system. The water you get has great taste. It is wise not to use an RO system unless hard water goes under 10 grains per gallon. If you have very hard water, you need no turn your head for other water treatment solutions.
Setting up a water softener is good before installing the RO system. Sometimes scale build-up can destroy the RO system. It also damages the other appliances in your home. Read the related articles to know more about hard water that destroys your RO system. Take proper care of the unit and get pure water.
Step 2: The Reverse Osmosis Membrane
Follow preliminary filtration appears the true art of Reverse Osmosis system.
The membrane is made of synthetic plastic mater. Water moves through this membrane. At the time of passing water, it needs more pressure no doubt. The force compels molecules to pass through the membrane.
But calcium, sodium, and magnesium remain in the water. There are some other things remain with water namely virus, glucose, urea and bacteria.
We have a reverse osmosis system that is tested as well as certified for the reduction of:
- Chromium (hexavalent & trivalent)
- Nitrates and nitrites
- Total dissolved solids (TDS)
- Cyst (cryptosporidium)
Water Right utilizes thin film composite membranes with the Impression series RO and the eclipse RO system. This membrane can resist bacteria break down. The rejection rate is 95% to 97% on an average. The TFC membranes aren’t chlorine resistant. For this reason, people like to use carbon prefilter.
Steps 3 & 4: Post Filtration and Final Polish
Water goes through a second carbon filter before you get it ready for drinking. This stage removes the rest of pollutants come from the past membrane.
Keep this water in a storage tank. Here water waits until you consume it.
Lastly, there stays line activated carbon filter that gives final polish of water. The flow is of water is coming from the faucet. It is used to eliminate remaining flavors and odors that come from the holding tank or the system hoses.
The polish is a step that ensures the drinking water is unbelievably fresh.
Advantages of RO water purifier
- RO or reverse osmosis purifier is a welcoming solution for hard water.
- Suppose, PUreit Marvella is slim RO of RO water purifier.
- Reverse Osmosis eliminates mercury, lead, arsenic, fluoride, and chlorine. These things are responsible for the illness of the body. Lead metal is responsible for anemia and brain damage.
- RO filter is greatly used to remove usually found a lake, Cryptosporidium in the river, lake, and public deliver water.
Disadvantages of RO water purifier
- Removes essential minerals: The main demerit of this purifier is that it removes natural minerals from water. As a result, the taste is greatly affected. Moreover, these natural minerals are very much essential for our body. There is a report that it removes iron, calcium, sodium and magnesium from water.
- The main problem of the RO water purifier is that it fails to destroy bacteria and viruses from water. Microorganisms may pass through the filtration system. So there is health risk of consuming such type of water. For this cause, it is suggested to use RO through the UV radiation as it can destroy virus and bacteria from water.
- Water taste altered: The taste of water little bit change here. The cause is that it removes natural mineral from the water. As a result, the taste is greatly affected in this filtration process.
How often do RO filters need to be changed?
Routine maintenance is the precondition to get the optimal efficiency of the Reverse Osmosis systems.
As a procedure of thumb, the Reverse Osmosis system has 3, 4, 5 filter stages. We aren’t discussing the details of each stage. Here we outline some main maintenance procedures that are essential for the most of the RO system.
First: At first you have to pass water through a pre-filter. The prefilter removes dirt, sand, sediment and other pollutants from water. You should change the filter after using six months otherwise it can clog. The flow rate of water will be less and you must change the filter.
Second: The following statement is a carbon filter that is made to eliminate odor and chlorine taste. It is very much essential as chlorine may destroy the RO membrane. You have to replace the filter after every six to nine months.
Third: In the third stage of filtration process the unit uses pressure to move water through the membrane. Lastly, you may get pure water on one side. The dirt remains on the other side of the membrane. This is the most popular method.
This is called the normal process of the RO system. Here pressure is not essential. In this stage, solvent moves from low solute to the high solute concentration.
Water goes inside the RO membrane at normally 35 pounds/ square inch. It means two drops per second. The membrane pipes down the rejected pollutants. One needs to replace the RO membrane after every two to three years.
Fourth: To the end of the cycling process, one has to add carbon filter stage to get polish water. This level eliminates the remaining odors and taste to make water fit for drinking. One must replace the carbon filter following every six to nine months.
What if I forget to change the filters?
The system starts to produce less amount of water gradually after using for a long time. The performance of the filter wouldn’t be better. Decreasing the product of water is a good sign to change the membrane or filter of the purifier.
Therefore it’s a fine idea to adjust a reminder. You should better change the membrane and reminder in schedule time.
How Can I Purchase an RO System?
You may have some question regarding the RO technology or system. Make contact with the local dealer. Besides you can contact the water supply management team who can show you the right path to choose the purifier.
