Methods Of Removing Heavy Metals From Water

What Is RO?

The RO system has many best characteristics. The great-quality features make this system the best one. Does reverse osmosis remove heavy metals? It is a perfect solution for the removal of contaminants like heavy metals. The system makes water pure and safe for drinking. 

It is a process of filtration that uses water pressure. This pressure forces the moving of tap water through a membrane. This membrane contains a large number of tiny holes. These only allow water molecules to pass. They eliminate all large molecules of contaminants such as heavy metals. The size of heavy molecules is larger as compared to water molecules. 

What do Reverse Osmosis filters remove?

RO filters enable the removal of all kinds of heavy metals. It includes sulfates, fluoride, arsenic, and many others. On the other hand, it removes some of the healthy minerals from water. For instance, it eliminates calcium, potassium, etc. 

The RO system depends on the RO filters. Every system has different filters. The RO filters vary due to water pressure. The industrial RO filters are with the quality of high pressure. So then, they are more effective in the removal of heavy metals. As compared to these filers, the low-cost house filters are less effective. 

The RO system is not a water softener. So,it does not produce soft water. Therefore, activated carbon is necessary for the more removal of hard contaminants. The activated carbon in the RO system removes 70 percent more harmful pollutants. In addition to it, it also enables the removal of pesticides. 

Do I need a RO filter to get clean water without heavy metals?

The working of RO filters with activated carbon makes it the best combination. With this combination, the drinking water becomes cleaner. For the last 10-15 years, it is one of the famous and suitable solutions for filtration. It is an excellent option for the household use of drinking water. 

Before purchasing the RO system, check the condition of the water. After that, purchase the specific system of RO which fulfills your needs. 

Working of RO system that removes the heavy metals

Reverse osmosis removes the pollutants and heavy metals from the water. The semi-permeable membrane is the central part of the system. The water pressure moves the water through the membrane. After that, it removes heavy metals. It is a form of cross-flow filtration method. It is a very effective method. The RO system has a longer lifespan. In its all life, it ensures to deliver the excellent performance of it.

Do all RO Systems Require Chemical Cleaning?

Yes, the proper functioning of Reverse osmosis needs chemical cleaning. The main reason for cleaning is that every time RO systems ensure the removal of heavy metals. The membranes of the system are an essential component and require chemical cleaning. This system comes with a cleaning skid for the more straightforward process of cleaning. Different types of chemical agents are present in the market.

After using of the system, the minerals deposit on the filter. Over time the functioning of the system may affect. The chemical agents clean the system and remove the mineral deposits. After the removal of mineral deposits, the system again works like a new one. Thus, you will enable to always get clean and pure water. If you maintain the system, it will more remove heavy metals.

Disadvantages of RO

As we told the great benefits of using it, it also has some disadvantages. It wastes water after the production of cleaned and filtered water. This system requires professional maintenance. Hence, the systems work great. The filters of this system need to change after 3 to 6 months. The removal of heavy metals also removes healthy minerals.

Otherwise, the system has not any significant faults. The use of it is easier. You can comfortably use it and gain pure filtered water. The resulting clean water is free from chemicals and heavy metals.

Is demineralized water without heavy metals produced by RO good for you?

The reverse osmosis produces contaminants-free water. But this demineralized water is also without many essential minerals. The necessary and healthy minerals are necessary for the development of the body. This system eliminates heavy metals as well as beneficial minerals.

In reality, this water is not harmful to health. It is safe for health and body. On the negative side, this water also does not provide significant benefits to the body. The lack of healthy minerals may change the taste of the water.

Alternatives to RO for the removal of heavy metals

Most of the tap water is potable. It means that this water is ready for drinking. For example, Europe and North America provide safe drinking tap water. Thereby, the top priority should reduce harmful contaminants like heavy metals. In addition to it, the taste of water should better. The best alternative to RO is using the activated carbon filter.

There are numerous benefits of using carbon activated filter. Likewise RO filters, it is also great in their performance. The carbon-activated filters are the best for removing heavy metals. With the removal of contaminants, they will never eliminate healthy minerals. They can easily install in the house and also low in cost.

There are numerous alternatives to RO. With all alternatives, you can eliminate harmful contaminants. It includes iron exchange and UV purifier methods. Besides, you can also use the ozone and distillation process. At last, the resulting water is free from contaminants.


Reverse osmosis is a unique, innovative technology for the cleaning of water. It provides fresh water in the whole world. Fresh and pure water is free from harmful chemicals and heavy metals. Many industries use the RO system for water cleaning. Further, it is also an excellent system for household use.With this article, you will know about does reverse osmosis remove heavy metals. Municipal water may be safe, but they also contain heavy metals. So, the purification of water is necessary. The RO system removes all different types of heavy metals.
