Reverse Osmosis, also known as RO, is a water purification technique that forces water through a fine membrane to remove impurities that cannot be seen by the naked eye. Water purifiers are made up of a number of filters that can be divided into two stages: pre-RO and post-RO.
The Pre RO filtration stage usually consists of a Carbon Filter and Sediment filter
Sediment filter (SF) The Sediment filters remove suspended particles such as dirt, sand, and rust from the water source. It reduces particulate impurities and prolongs the life of your Carbon Filter.
Carbon filter – The second stage of the filtration process removes dissolved oil, chlorine, color, and odor. It also removes organic impurities like harmful pesticides. It can also remove bad taste and odor-causing organic substances from water.
Mesh filters are also included in Pure Blue H2O water purifiers to add an extra layer of purification. This further protects against any particulate impurities.
A RO water purifier’s core is its RO membrane.
RO Membrane After all the pre-filtration steps, water is pumped through an RO membrane. The RO membrane is a semi-permeable and thin membrane with very few pores. RO membrane is very thin and allows only purified water to pass through it. It rejects all impurities.
To get the water filtered through an RO membrane, the pump presses water to create pressure. This high water pressure ensures that only purified water passes through the membrane. It leaves behind chemicals, pesticides, heavy metals, dissolved salts, and other contaminants.
A RO water purifier is recommended for households with high TDS (more than 300ppm). It removes hardness from water and makes it more pleasant to drink. This water purifier technology is most effective in removing heavy metals and chemicals such as lead, mercury, arsenic or fluoride. It can also remove microbial contaminants such as bacteria, protozoa, and cysts, to provide safe drinking water.
Pure Blue H2O water purifiers include a microfilter membrane, which is a post RO stage that ensures water is purified at least twice.
These multiple stages together makes Pure Blue H2O’s Advanced RO Purification, which ensures that your drinking water is safe and free from any impurities.
Our water purifiers can also be used to enrich RO water with essential minerals such as Calcium and Magnesium.
This article should have given you a better understanding of the workings of an RO water purifier. This article should assist you in making an informed decision when choosing the right RO water purifier to fit your needs.
