Reverse Osmosis F.A.Qs

As one of the most effective ways to purify water, reverse osmosis has become more and more popular. Many homeowners buy reverse osmosis water filtration systems to purify water to get water to drink, cook or even wash. However, some people know less about reverse osmosis. Fortunately, we have compiled this F.A.Qs for those who don’t know much about reverse osmosis.

1.What’s the definition of Reverse Osmosis?

The core part of a RO system is a semi-permeable membranea that only allows water molecules to pass through. When pressure is applied to one side that water needs to be purified, water molecules is forced to pass through the membrane, while other contaminants are still left in that side. The whole process is called reverse osmosis. This process can separate clean water from contaminants.

2. Commercial vs household reverse osmosis systems?

Actually, they are similar to each other, because the basic procedure is same. The only difference is that commercial or industrial reverse osmosis systems tends to be much stronger than a household model. For example, pumps and spiral would membrane are used in commercial systems, making them much stronger and normally, they are huge in size. However, they are also costly.

3. Is Pretreatment necessary?

The answer is yes. It is recommended to use a pre-filter to remove silt and chorine, because this can prevent the membrane from plugging up or being damaged. The life of a RO system depends on the life of membrane.

4. How much pressure is required to conduct reverse osmosis?

Well, this answer depends on the sediment and salt concentration in the source water. The higher the concentration is, the more pressure is required.

5. How pure is the RO water?

The purity depends on 2 factors. Of course, the membrane is the first factor. Generally, the membrane has a rejection from 92% to 99.5%. Of course, the higher rejection means the feed water can be purified better. The second factor that may make the membrane weak is the types of TDS.

6. How to clean a reverse osmosis system

The place needs to be clean is the RO tank. First, you need to disengage it, and then wash it and clean it.

7. What Is the Extent of maintenance to expect?

Actually, membrane is very weak to many large matters. Therefore, to protect the RO membrane, the pre-treatment water filter should be cleaned every month. This clean process may need 1 hour. If the feed water is very dirty, you need to do this frequently. And you need to make your pre-treatment filter not blocked.

8. How much does run a RO water filter?

If you have a RO system in your kitchen, of course, you need to pay for it. This means the maintenance cost is essential. However, the maintenance cost is influenced by several factors, including the purity of your water, the price of the replacement filters, and the labor. If the feed water is very dirty and contains so many contaminants, the membrane tends to be weak and you need to change its filters frequently. If the price of replacement filters are very high, it will become a burden for you when you need to replace it. If you have to hire someone to maintain your RO system, the labor cost is also a good problem. You’d better change its filter yourself and this process is very easy. This can save some money for you.

9. Can it remove bacteria?

Of course, the answer is yes. The membrane will not allow bacteria to pass by. And a UV sterilization system is used at the storage tank to kill bacteria. This process also happens during its self-cleaning process. Therefore, you’d better choose an opaque tank or just paint the tank black, so algae cannot grow in the tank.

10. When to change its filters

Even if RO membranes can last several years, how long they can last depends on several factors. If a high ion level is noticed in the filtered water, this means you need to change it. Many RO systems include an indicator that will tell you when to change its filters. Generally, every 6 months to 1 year, you need to change the filters.

CONCLUSION

For, most of us, we may dislike the bad smell and taste in our tap water. And there are actually many contaminates which may cause serious health issues. A RO system is really a must-have investment on our healthy both for ourselves and our families. We also have responsibilities to protect our environment. We can reduce the use of bottled water. Therefore, we can reduce the pressure we place on the environment. If you are looking for the best reverse osmosis system, our list can help you quickly find the right one according to your needs.
