Reverse Osmosis (RO) is one such term that is often used while talking about water purifiers. Let’s check out what is RO and why it is important in your water purifier. First, let’s understand how osmosis work with the example of a raisin.

When raisins are kept in a bowl of water, they start swelling because of osmosis. Basically, osmosis happens when water moves from more concentrated part (water bowl) to the less one (raisin) through a semipermeable membrane (skin of raisin). With reverse osmosis, it is the opposite. The water moves from lower concentration to higher, under pressure.

In a simple filtration process, water is passed through a simple membrane which keeps most of the contaminants out. In case of an RO system, it works with the cleansing of water at a much higher level. Here is a brief guide which explains how an RO purifier works.

  • How does reverse osmosis work? RO filters the water through a membrane-technology method. It removes various types of large molecules and ions from solutions by applying pressure to the water when it is on one side of a selective membrane. The solvent is allowed to pass through the membrane on the other side and that is your filtered water.
  • What RO does to your water? RO filtration improves the taste and appearance of water by removing contaminants. It eliminates many chemicals, such as lead, arsenic, barium, nitrates, etc and carbon pollutants. Also, it has an added advantage of removing aqueous salts from the water. The membrane has a high bacteria rejection rate. It does everything to make your water safe.
  • What are these contaminants? what can they do? The presence of these contaminants is the cause for a wide array of degenerative diseases, such as hardening of the arteries, arthritis, kidney stones, gallstones, glaucoma, cataracts, hearing loss, emphysema, diabetes, and obesity. The minerals available in hard tap water are rejected by cellular tissue in our body. It can cause very possible internal damages. So, it is beneficial to invest in an RO water purifier from a trustworthy brand than buying packaged drinking water every day.
  • What else can RO purifier offer? With technological advancement, today’s RO purifiers come with various indicators alerting about servicing and replacement required by the cartridges. RO purifiers also come with different types of fittings such as under the sink, mounted RO with storage or without storage, etc.
