Ratings for Reverse Osmosis Water Systems – Understanding How Reverse Osmosis Works

Clean and potable drinking water is needed by many a reason why a lot are searching the internet about ratings for reverse osmosis water systems. This article will help you know more about reverse osmosis water systems.


An average human body needs water to keep his body system working properly a reason why we need clean and potable drinking water – that’s the job of ratings for reverse osmosis water system. Reverse osmosis water systems filters and purifies water to be safe and secure for human consumption.

What is Reverse Osmosis?

To understand the phrase reverse osmosis then it is best to start understanding what the word osmosis means. You can search for it in any dictionary but the meaning will all be the same. Osmosis is the movement of any liquid or solvent into a semi permeable membrane or wall into a solution with higher concentration in order to balance the concentrations of both solutions on the each side of the membrane.

So reverse osmosis is a process where water is forced to pass through a semi permeable membrane or wall that has very tiny pores or holes. The only thing that passes through the wall or membrane is clean and purified water and impurities and particles that are too big to be able to pass through the membrane will be left behind. So basically that is how ratings for reverse osmosis water systems work.

Is Reverse Osmosis Needed?

You may ask yourself if you need ratings for reverse osmosis water methods in your own household. Now if the drinking water you have in your city or municipality comes from the utility suppliers, there is almost no possibility of having a reverse osmosis machine in your house or facility. The water supplied by utilities is most of the time microbiologically safe and is treated to meet the standards and requirements for aesthetic use of water for public consumption.

However if you obtain water from a private suppliers then you may have to think again. Water from private sources has to be routinely tested to determine if it is safe for consumption. It has to be safe from any microorganisms, unwanted chemicals and any other forms of contamination.

There is no water treatment device that can remove all kinds of unwanted substances that flow together with water. All devices have their own pros and cons but individual households must determine if they need any additional devices for water treatment like – ratings for reverse osmosis systems.

How Does the Reverse Osmosis Systems Work?

If you have read the paragraphs earlier then you understood how ratings for reverse osmosis systems work. Water is forced through a very fine membrane or wall to be purified and have all its impurities left behind on the other side of the membrane. However if the water is from a well or other sources the water has to be disinfected and filtered first before undergoing reverse osmosis process.

In reverse osmosis water is treated in 5 steps. First the initial filtration were well water or tap water by using a pressurized pump, the water passes through a pre-filter or a particle filter to remove sediments like silt, clay and sand particles. Second, the water will then be forced to pass through a filter made from activated carbon to trap certain contaminants and minerals that may harm the membrane and the human health like pesticides, chlorine, copper, mercury and others.

Third, water will then be transferred under pressure to the reverse osmosis module or device allowing potable and clean water to pass through the small holes in the walls of the membrane. Those impurities that are left on the other side of the wall will be flushed. The treated water will be sent to tank for it to be stored. The final stage in ratings for reverse osmosis methods is the further improvement of the water’s taste and its smell by letting it pass through a filter of activated carbon.

What Unit Should I Buy?

Units of ratings for reverse osmosis processes are rated depending to the amount produced of treated water. One unit can produce 50 liters of water treated every day. Such unit is rated 60 psi of water pressure and with 25 degree Centigrade of water temperature.

Where to Buy One?

Units for reverse osmosis can be bought from any hardware, department stores or any dealers of water equipment. You can look for the companies listed under the word Water or Water Companies in phone directories. Devices like these can be bought from certain websites from the internet as long as you are patient enough to look for one.

How Much Dose One Cost?

The prices of reverse osmosis devices are varying. A portable one will cost at least $400 while a larger one will be priced from $2,500 or higher. Pre-filter replacements are priced from $100 to $200 each.

What are the Benefits?

The reverse osmosis procedure removes the dissolve solids, minerals and salts in that water which in turn improves the taste of water. The treated water will not produce any lime scales in coffee makers and kettles. Reverse osmosis units can remove harmful contaminants like pesticides and heavy metals like mercury and lead.

Is it Safe?

Yes it is safe, since there are no additives in the water and it undergoes a safe and secure systematic water treatment that will result to a clean and potable drinking water.

Does it need any Maintenance?

Units of ratings for reverse osmosis processes must be maintained according to the recommendations of the manufacturer. Generally you have to be changed annually the sediment pre-filter and the pre-filters made from activated carbon. But if the water that’s is entering the unit contains many amount of chlorine, sand and any other substances then you have to change these filters twice a year or every 6 months. The membrane of the unit can last for several years but it has to be replaced according to the timeline dictated by the manufacturer.


The main reason why reverse osmosis systems or hyper filtration was invented, it is because humanity needs access to clean and potable water that is suitable for anybody’s use. Ratings for reverse osmosis waters systems will always be one of the best way in treating and making sure that our water will always be clean and safe for consumption.
