What is Reverse Osmosis?

Reverse Osmosis, often abbreviated as RO, is a crucial water purification process that merits a comprehensive understanding. It is a highly effective method for eliminating various impurities, including organic substances and dissolved solids, from water sources. A standard reverse osmosis system typically comprises three distinct filtration stages: a pre-filter, a semi-permeable membrane (the pivotal filter), and a post-filter.

The process unfolds as follows: Initially, the pre-filter plays a vital role in eliminating contaminants such as sand, dirt, silt, and chlorine. This initial filtration not only enhances water quality but also safeguards the integrity of the semi-permeable membrane. Subsequently, the semi-permeable membrane serves as the central element of the RO system, allowing only water molecules to permeate while blocking out undesirable contaminants such as heavy metals and chemicals, effectively segregating them on the opposing side of the membrane.

This core process of reverse osmosis sets it apart from other types of water filtration methods, as it efficiently eliminates major water impurities. The waste water, now laden with separated contaminants, is directed to the sewer, while the purified water is stored in a dedicated water tank linked to your countertop faucet. Upon opening the faucet, the stored, filtered water flows out for your use. Prior to reaching your glass, the post-filter undertakes the final purification step, ensuring the removal of any remaining odors and sediments.

The critical component of an RO system is the membrane. It holds the key to determining which contaminants are filtered from the water. Commercial RO systems predominantly employ membranes constructed from materials such as polyamide, acetate, and polysulfonate. These membranes consist of a support layer measuring 100 microns in thickness and a 0.25-micron thin skin. This arrangement permits only water molecules to traverse the skin, effectively excluding all other substances.

In water, dissolved solids are a constant presence, manifesting as a specific concentration in the feed water. For instance, if the Total Dissolved Solids (TDS) measure 400 parts per million (ppm), the purified water produced by an RO system may contain as little as 20 ppm or 40 ppm. This translates to reverse osmosis being capable of removing a remarkable 90% to 95% of dissolved solids from the feed water. The design of most RO systems is guided by the TDS level of the feed water, with lower ppm values in the purified water being indicative of superior performance.

Reverse Osmosis F.A.Qs

More and more people have realized that their water needs to be purified before drinking and cooking. And many of them buy reverse osmosis systems to purify the water from water companies. However, there are also some people don’t know something about reverse osmosis. Therefore, here, these F.A.Qs may help you quick know something about reverse osmosis.

What’s the definition of Reverse Osmosis?

Reverse osmosis use a semi-permeable membrane to separate minerals as well as other contaminants from water. This is because this semi-permeable membrane only allows water to pass through. If pressure is applied to the water that needs to purified. Only water molecules are allowed to pass through the membrane. And all the contaminants are left in its original side. On the other side, RO water is available and clean, safe for consumption.

What is the Difference between commercial and household reverse osmosis systems?

Actually, the basic procedure is no different from each other. The only difference is that most commercial or industrial RO systems use many other components to make the RO systems much stronger. For example, pumps are usually used to make them much stronger. And spiral wound membranes are also used to increase the surface area. In a word, commercial RO systems are much stronger but much costly at the same time.

Is Pretreatment Necessary?

Of course, the pretreatment is necessary. In a RO system, the pre-filter is used to remove chorine as well as silt that may make the membrane plugged up or damaged easily. Total Dissolved Solids (TDS) are also got rid of by pre-filter.

How much pressure is needed to conduct reverse osmosis?

The pressure applied depends on the salt and sediment concentration in the feed water. If the concentration is high, the more pressure is needed.

How Pure is the RO Water?

Purity of RO water depends on 2 factors. The first is the rejection ratio of the membrane which is normally between 92% and 99.5%, and the second factor is the types of TDS in the original water which makes the membranes become weak, thus affecting the purity of RO water.

How to clean the RO system?

First, you need to disengage the RO tank, and then clean the tank, and then at last wrap up Reverse Osmosis Tank Cleaning. Learn more about this.

What Is The Extent of Maintenance to Expect ?

In order to protect the ro system, the pre-treatment filter is needed to clean every month and the whole process only costs about 1 hour. If your feed water contains much dirt, you need to check the prefilters every week to notice if they are blocked.

How much does run a RO water filter?

Once you have installed your RO system, to keep it running normally, the maintenance cost is needed. The cost depends on several factors; the purity of the feed water, the cost of replacement filters and labor. If the feed water contains too much amount of pollutants, the membranes are prone to be weakened very soon, so you need to change its filters on a short time basis. If the replacement filters are expensive, this also will increase your cost when you need to change them. If you need to hire some to maintain your system, this will also be a big budget. You’d better change them yourself and the process is pretty easy.

Does It Remove Bacteria?

Bacteria are get rid of by the membranes and while at the storage tank, the system use UV sterilization system to kill the bacteria when water is passed through. This process will happen during the cleaning process. Therefore, it is highly recommended to choose an opaque tank or paint your tank black, so that algae cannot grow in it.

When or How Long to Change the filters?

Although RO membranes are designed to last several years, the time they last depends on many factors. If you notice a high ion levels in your RO water. This is a sign that you need to change it. Generally, manufacturers recommend to change the filters every 6 to 12 months. Most systems have indicators that can remind you when you need to change them.


Because of the obvious benefits of reverse osmosis, the RO system has become one of the most important and useful technological breakthroughs in the world. It can effectively offer plenty of clean, safe and healthy water at a reasonable price.
