Benefits of Reverse Osmosis Water Filtration System
Undoubtedly, reverse osmosis water filtration systems are becoming widely popular to obtain household pure drinking water. The reason is quite obvious- they constitute one of the most effective methods to purify daily usage water. Some of its major advantages are:-
- Reverse Osmosis technology is one of the best means of getting pure water due to its capability of eliminating 95-99% of total dissolved solids i.e. TDS.
- A good R.O system has obvious health advantages on the perspective that it can remove the health hazardous heavy metals like lead, mercury, arsenic etc which have drastic health consequences. Lead is known to lead to increased blood pressure, causing fertility problems, development of nerve and muscle damage and even causing brain damage and severe anemia in children.
- Since RO process can eliminate all harmful micro-organisms and tiny germs that often cause infections, the purified water is especially considered safe for cancer patients especially under radiotherapy or undergoing chemotherapy. Their weakened immunity systems make the body extremely fragile and susceptible to infections and complications from these germs.
- According to a report of CDC, reverse osmosis filtration successfully eliminates the parasite, cryptosporidium which is often present in contaminated water. The parasite, if ingested can harm the small intestine and cause stomach cramps, diarrhea and fever. In children, it can cause dehydration and malnutrition.
- The taste of purified water is rated as the best or one of the best by many experts who compare the purified water obtained from various other filtration processes.
- Compared to other systems, the RO membrane lasts for a much longer period. The replacement or change span of water filtration units for other types of filtration is quite small in comparison to this.
- RO units are quite eco-friendly as they do not produce any new chemicals due to the filtration process running inside it.
- These systems are relatively quite small in size, thereby making them a perfect choice to install in modern homes.
- While it may look like that the production cost of water is quite high but it is actually quite cheap with pennies per gallon.
Selecting the Right RO Water Filtration System
With the technology being the top choice for most, it’s natural that the market would be filled with various brands showcasing different designs, makes and models of water filtration systems. Even though the basic technology is same, the output and quality of water differs according to the specifications and the quality of tap water fed into it. With it, it is best that the following factors should be considered before actually purchasing a RO water filtration system.
- Understand the tap water well
Before one even looks into any filtration system, it is important to get the tap water analyzed. This helps gain insights into the type of contaminants and their concentration in the water which needs to be purified. This helps in getting the RO with the right membrane as well as with right stages of filtration systems to eliminate every last bit of contaminants. An unsuitable filter would leave the contaminants inside the water and defeat the purpose of purchasing a water filter. For getting the tap water analysis, its best to get a water quality test done and a report prepared by the local water authorities. Few companies also get this test done free of cost to ensure that a right choice is made on the filter.
- Keep in mind the required gallons per day
We already know that part water is purified and part water is used to wash away contaminants. Different systems require different gallons to give a specific amount of purified water. Systems may use anything between 3-10 gallons of tap water to produce a gallon of water. Hence keeping in mind you’re the family size, the amount of gallons of water required per day and of course the larger water bill has to be borne in mind. The right filter must meet all your personal requirements and needs as well as should be within his pocket’s means.
- Overall Price
While delving into the RO systems and purchasing one, it is important to understand that it is not exclusively the cost of the RO system alone. The cost and frequency of replacing cartridges and membranes, the maintenance costs, the water bills, and any other expense should give you a cumulative figure which must be what you consider when deciding to purchase. Without this analysis done, there is a high chance that a so called cheap system in the initial stages actually turns out to be a costly affair.
- The Membrane and its quality
We understand the RO systems generally have two types of membranes. Depending on the contaminants and specifically the chlorine content in the water, the right selection of the membrane needs to be made. Again they come in varying qualities depending on their leaves. Keeping your budget and all other considerations you can select anything from the base threshold requirements for your house.
- The Pre-filters
The pre-filters installed in the system should be able to adequately provide protection to the membrane and block contaminants that may rupture it or cause fouling or clogging. A top notch quality of pre-filter should be used at all times. Opting for a multiple pre-filters system is always a top recommendation for enhanced longetivity of the membrane. Generally every pre-filter requires a change anytime after six months while a membrane normally requires replacement after 2-3 years.
- Opt for 4-stage or above RO filters
Regarding RO filters, a four stage filter is the bare minimum criteria for good and standard purified water. The systems with fewer filter stages have proven to be less reliable and stable and often require frequent filter changes which can be as less as 4 or 5 months. Not only this causes a lot of inconvenience but it also proves costlier in the long run. A four stage or above filter provides a much thorough filtration apart from the filter lasting a minimum of 9 months or above. The quality of water is also much better with enhanced taste. Thus while the initial investment may be trifle higher, it proves cheaper in the long run.
- The Post filters
While most people look into pre-filters, post filters are often ignored. Predominant systems come with one post-filter but it is always recommended to opt for units with two post filters as it really gives out good quality water with essential minerals loaded back into it.
- Opt for solid ‘carbon block’ filter
Two types of carbon block filters are mostly used in RO systems. One is the ‘carbon block’ and the other is the granular activated carbon (GAC) filters. While the GAC filters tend to leak carbon powder, it often blocks the RO system and makes the membrane highly susceptible to getting ruptured on account of chlorine getting leaked through. In contrast the carbon block filters are not prone to leaking fines and thus last longer.
- Easy replaceable components
For future maintenance and ease of use, it is recommended to opt for units whose parts can be easily repaired, replaced or serviced for maintenance. The filters would require special attention here as they are the ones which need a change on an average, every six months. Their replacement should be an easy hassle-free affair. If you are able to change them yourself, then nothing beats it since it can really save on your service bill.
- Delve into components quality
Always go for a system with superb quality components. Ideally, it should be certified by bodies like BBU and other approving bodies for not only good quality but good craftsmanship as well like clean neat line connections and system fitting perfectly into a sturdy frame. These minor details go a long way in effective and long-lasting RO water drinking filter system.
- Check out the customer’s review
Customer’s reviews can give you a true insight in the pros and cons of a unit since they have actually used it or are using the product. Checking their comments online or even interacting with a live customer can present the true picture of the product.
- Always purchase from a reliable supplier
While the product authenticity and credentials are important; equally important is the reliability and the trustworthiness of the store or supplier from whom the unit is purchased. Remember to look into the supplier’s technical and parts support credentials along with the 24-hour and accommodating customer service. Again, reviews here are a big source of help.
- Check out the warranty status
Most systems come with a one or two year of warranty. Hence its best not be fooled by excessive length of warranties. The fine prints of the warranties must be read carefully and well understood before purchasing the best reverse osmosis system for your home.
Some Frequently Asked queries on Reverse Osmosis (RO) Water Filtration Systems Answered
In spite of the RO water filtration systems being a top choice for most households, the awareness about the system is extremely low. Consequently a lot of myths surround the system. Let’s answer some of the most frequently asked questions about it and dispel some myths surrounding it.
Q1. How do an industrial and a home reverse osmosis filtration system differ?
Ans. There is no difference in the technology and the process in both environments. The only difference is that the units and the materials used are of industrial strengths to meet the requirements of the bigger institutions adequately.
Q2. Is it true that RO systems waste a lot of water?
Ans. This depends on the definition of waste. A part of water is used to wash the RO system itself and to eliminate the impurities separated from the tap water. A similar comparison can be drawn to using water for various purposes like washing clothes, dishes cars etc or even to flush toilets. While the system does use more water for its operation in comparison to the purified water output, it is not so high that it makes a marked difference in the water bills. As soon as the storage tank gets full, the unit shuts down its operation and no water drains out. The drained out water can typically be equivalent to two or three extra toilet flushes per day.
Q3. Do RO systems remove the health minerals required by the body?
Ans. Most think that RO system strips away all essential minerals. However, very few realize that the minerals content in tap water is too negligible to have any health impact. Comparatively, a glass of orange juice would load your body with more minerals than a bathtub of water. Moreover, water contains inorganic minerals which cannot be readily absorbed by the body like they can be absorbed from various foods. RO systems remove these inorganic minerals and lend you the most pure, healthiest and natural drinking water.
Q4. Should a water softener system be installed before the RO system?
Ans. The hardness of the water comes from calcium and magnesium content which are the toughest challenge for the delicate RO membrane. A water softener removes these lime scale and replaces them with sodium ion which is much easier to remove by any RO system. Thus for areas having very hard water, a water softener system installation is recommended before the RO system. This can significantly increase the life of the membrane.
Q5. Does a RO system unit require electricity or energy?
Ans. Ideally, the system does not require any energy and runs on water pressure. It requires electricity only if one adds an electric pressure-boost pump or similar device to it which may be required in areas where water pressure fluctuates. Otherwise, no electricity is required.
Q6. Is RO system like a distiller?
Ans. Both processes are different though both effectively remove the ‘dissolved solids’ contents of impure water. Again both systems effectively use carbon filtration help to remove quite a few chemicals. Each system has its own utility.
Q7. Does RO filtration produce acidic water will low pH?
Ans. RO filtration may or may not affect the pH of the water as it removes the contaminants. Water pH is quite complicated and depends on varied factors. The human body itself can regulate the pH for balance and equilibrium. Thus it has no effect on the quality of water produced by the RO system. Even soft drinks and sports drink have an acidic pH.
