RO Water System Parts – how do they Work?

4 stage RO system parts

Reverse osmosis or RO is a water purification technology, which uses a semipermeable membrane to remove a larger particle from drinking water. Reverse osmosis can be applied to many things. To purify drinking water is just one example. Reverse osmosis is also applied for desalination, food industry, maple syrup industry, reef aquariums, window cleaning etc.

How does reverse osmosis work?

Reverse osmosis appears to be a complex process. Actually, it is not. In fact, it is a simple and straightforward. We will tell how you how does reverse osmosis work. We hope after you read the explanation, you will have a better understanding of this process. Before we start, here are some important things to know:

  • All of the reverse osmosis processeswork the same way
  • Most reverse osmosis systems look alike
  • All of the reverse osmosis processes have the same basic components
  • The real difference is not in the process, but the quality of the components. Specifically, thequality of the filters and membranes inside the reverse osmosis

Now, let’s talk about the process.

Reverse osmosis is a process which removes dissolved inorganic solids (for example, salt) from a solution (in this case, water).

How does this accomplished?

Let’s say we have a tank of water. One side is filled with saltwater and the other is filled with pure water. The saltwater and pure water are separated by a semi-permeable membrane. Now, we would apply pressure to the saltwater side. The pressure applied is enough to counteract the natural osmotic pressure from the waterside and push the saltwater through the filter.

This will take about 50 to 60 bars of pressure. Because of the salt molecules size, only the smaller water molecules will make it to the other side. Thus, adding fresh water to the pure water side and leaving the salt on the other.

What are the reverse osmosis machine parts?

Although reverse osmosis machine parts can be different one from another, here are the basic parts that are common in RO systems:

  1. Cold water line valve

It is a valve that fits into the cold water supply line. It has a tube that is attached to the inlet side of the reverse osmosis pre-filter. It is the water source for the reverse osmosis system.

  1. Pre-filter(s)

The number of pre-filter used in a reverse osmosis system differs from one another. Indeed, there may be more than one pre-filter used. The most commonly used pre-filter is the sediment filter. This kind of pre-filter is used to remove dirt, sand silt, and another sediment. Other pre-filter, such as carbon filter, can be used too.

The Waste

Now, it is also important for you to know about reverse osmosis wastewater. When we are trying to produce clean water, we will have to deal with wastewater. This is the truth. It can be said that all reverse osmosis systems produce wastewater.

Some amount of water goes into the drain. However, with properly designed and efficient system, the reverse osmosis wastewater ratio can be set to the lowest point. For example, the ratio of wastewater and purified water is 1:1. It means, one part is wastewater and one part is purified water. With the best system, you even do not have to waste any water that you do not have to.

 

How Does Reverse Osmosis Work and What It Can Be Used For?

Reverse osmosis has allowed us to produce more drinking water especially in a water-scarce region like the African continent. But you might be asking how does reverse osmosis work in all actuality? Well, you probably have heard of the term of osmosis before this. It is a natural occurrence where a liquid with low solute consistency will travel to high solute consistency through a semipermeable membrane. Reverse osmosis does the very exact opposite of it. It allows the liquid to travel from the high solute consistency to the low. In doing so, it will separate the pure water from the minerals, ions, and other molecules such as salt.

The next question on you mind would probably be how does reverse osmosis work to filter water. Reverse osmosis water purification system will use a certain filter technology to turn brackish or saline water into drinking water. The device that is used might varied, but they use the same type of technology. Within each device, there will be different kinds of filter membrane that will separate the bad molecules from the pure water.

reverse osmosis filtration

First, there is the sediment filter, or two, which will remove the bad molecules or materials from the water. After being separated from tangible particles, the water will still be filtered through a carbon filter. While the sediment filter is used to trap non-organic materials, the carbon filter will remove the organic materials such as chlorine. Just like the sediment filter, there will usually be two carbon filters within the device. After that, the water will go through the reverse osmosis water filter. In the final step, the water will be processed with a UV light which will kill the bacteria still in the water.

Other Uses of Reverse Osmosis

 

RO for Home

RO for homeReverse osmosis has so many different functions in life, but one of the best thing about it is that it can be used in our own home. The use of RO for home is varied but mostly to purify water. Reverse osmosis for water treatment at home is very easy to use nowadays. You can even get the device at the store for a rather affordable price. Whether you live in the dry place or water-rich environment, using a reverse osmosis can save you a budget to buy clean water.

The use of reverse osmosis at home is varied. Whether you are using the government water or your own well, RO can be very useful.

Reverse osmosis for well water is typically suitable for those who live in the bad water area. For instance, back then in Haiti after the earthquake, the well water turned muddy and undrinkable. By using the reverse osmosis technology, they were able to turn the dirty well water into a drinking water. This can also be used in a regular well water as a precaution as it will remove bacteria and particles that might be in the water.

Turning Salt Water into Drinking Water

There is another use of this process that will benefit so many people all around the world. The use of reverse osmosis for desalination is one of the most amazing breakthroughs in the history of human being. If you live where the sea water is the only available source of water, you will still be able to survive using the reverse osmosis device. By using the device, you can separate the saline solution from the pure water through the membrane within the RO device itself.

Aquariums Benefits

Reverse osmosis water purification systems are not just used to create more drinking water. There are others benefits outside home use of it. For instance, it can be used for the aquariums. But how does reverse osmosis work for aquariums?

Well, the system is used as a replacement of regular water when filling in the aquarium. That is because the pure water from the RO is cleaner and does not contain things like minerals that can ruin the ecosystem in the aquarium. By using the reverse osmosis system and deionization, you will create a healthy environment and ecosystems for your animals within the aquarium.
