Water purification process is something that has existed even in the past. Just like any other technology, water purification processes have developed from conventional methods to the most modern technologies that are being used to purify water. Water is among one of the most sensitive sectors and everyone is always keen to consume clean, safe and pure water. I am sure most of us have used water purification technologies but might not be aware what they are.
Among the many water purification processes available, reverse osmosis is one of them. Most people think that it is a complicated process which is not true. Reverse osmosis is a very simple and direct water purification process. Majorly, it has been used in the conversion of seawater into drinking water and to desalinate water. For some time, it has been in use and the only way to make things clear is to get to know what reverse osmosis is all about.
Reverse osmosis has proven to be to be very effective, reliable and trustworthy in terms of contaminant removal. In this article, I am going to discuss reverse osmosis in details and I am sure before we are done, you will find all the questions you might been having on reverse osmosis.
Before we define Reverse Osmosis, let’s first get to understand the natural osmosis process. Osmosis is all about balance. If there is a contact between two fluids with different concentrations, they will mix together until a uniform concentration is attained.
Now let us assume that these two fluids are separated by a membrane that will only allow the fluid to pass through leaving the dissolved solids behind. If this be the case, the lower concentration fluid will pass through the membrane into the region of higher concentration under normal circumstances.
After sometime, water level in one side of the membrane will be higher and this difference in height is termed as osmotic pressure. Reverse osmosis occurs now when a pressure higher than the osmotic pressure is applied. This reverses the natural process and leads to reverse osmosis. The fluids in the region of higher concentration will be forced back into the region of lower concentration leaving the dissolved solids back. This principle is the one applied to purify water using reverse osmosis.
The natural osmosis cannot aid in water purification since it will increase the concentration of water instead of minimizing. For the process to work, the water must be pressurized at a higher pessurer as compared to the osmotic pressure. During this process, the region of high concentration will become more concentrated as the water will be forced to pass through the membrane leaving back the dissolved solids.
Reverse Osmosis therefore is the process through which water of high concentration passes through a semi-permeable membrane into a region of low concentration. The semi-permeable membrane utilized must be able to eliminate water contaminants. This membrane has the ability to allow certain molecules to pass through and prevent others from penetrating.
Unlike the natural osmosis process that does not need energy, reverse osmosis uses energy to work. The process allows pure water to come out as output as water with high contaminants concentration is held back by the system.
Reverse Osmosis Water:
Reverse osmosis water is one that is free from any contaminants and minerals. In other words, this is water that is pure. A reverse osmosis is composed of different units. Water with impurities goes through the system and comes out as pure water. The purity level of the water that comes out is determined by the type of membrane installed in that particular system being used.
This is because there are different types of membranes and the type of membrane determines the amount of dissolved solids it is able to remove. This water that has been forced out through a semi-permeable membrane with the ability to eliminate water contaminants is the one now termed as reverse osmosis water.
There are different types of membranes and the type of membrane determines the amount of dissolved solids it is able to remove.
Reverse osmosis is a reliable, trustworthy and effective technology that has proven its ability to eliminate majority of water contaminants to produce high quality, pure, clean and safe drinking water. It is commonly known for its application in drinking water purification.
Reverse osmosis water has many application including both domestic and some industrial applications that need mineral free water. It is highly encouraged that you do prior treatments for your water before allowing it into the system. This protects your membrane and prolongs its life span therefore saving costs from unnecessary repairs.
With the proper management, service and maintenance, your reverse osmosis system will be able to give a quality and a long-lasting service.
