Water Purification: How Does Reverse Osmosis Work?

Table of Contents

Do you know what reverse osmosis is and how reverse osmosis works? You’ve definitely heard of famous bottled water companies like Aquafina, Bisleri, etc. who provide clean and safe water to drink. Have you ever thought about how they provide us with this water? These big companies use the latest technology of Reverse Osmosis to provide people with pure purified water. It is a difficult process to know the whole purpose of purification through Reverse Osmosis but we will guide you through the whole process of Reverse Osmosis.

Reverse Osmosis (RO) produces fresh, great-tasting water and is regarded by many as one of the most successful water filtration techniques. Several applications for RO systems exist, such as tap, aquarium, whole-house and restaurant purification. It doesn’t matter what quality of water do you have, there is always a type of RO system that will work for it. Here, we have mentioned the meaning of reverse osmosis, its benefits and where they are used. 

What is a Reverse Osmosis (RO)?

The earlier purification system used carbon water filters such as those found in typical pitcher filters or fridge filters that would go through a long process to clean the waters. On the other hand, Reverse Osmosis (RO) is a thorough water filtration method that can handle several water quality issues. High pressure is used in reverse osmosis (RO) to push water across a membrane to remove impurities and unwanted compounds. This procedure is typically a single phase of a multi-stage filtering procedure used in a standard Filtration System.

Reverse Osmosis Principle

Reverse Osmosis works on a simpler process in which a membrane is present through which massive molecules of the solute cannot pass and instead stay on the side that is under pressure. On the other hand, the membrane does not prevent the pure solvent from passing through. When this occurs, the solute’s atoms begin to gather on one side of the membrane while getting diluted on the other. Additionally, there is some variation in the complexity of solutions. Fundamentally, reverse osmosis occurs when the solvent crosses the membrane across a gradient of concentration. Essentially, it helps to move water from one concentration to another.

How Does Reverse Osmosis Work?

To understand how reverse osmosis works, we must first focus on what is osmosis and how it occurs. Osmosis is a method by which water moves from a solution with a lower concentration into a solution with a greater concentration through a semi-permeable membrane. In other words, the filter equalizes the levels of polluted and pure water, which is not what we want for the water we consume. Such motion creates Osmotic pressure.

In reverse osmosis, pollutants are pushed from high concentrations to low concentrations of water by applying pressure to compensate for the pressure created by osmotic forces. The polluted water attempts to flow into the water that is pure as it gets forced in the opposite direction, but because it has to first go through a filter, the impurities are stopped and just the pure water can pass, giving us the most sterile drinking water imaginable.

Sediment filters, pre-carbon blocks, reverse osmosis membranes, and post-carbon filters are commonly used in reverse osmosis. These all filters have their specific uses as mentioned.

Activated Carbon

Sediment Filter

In order to keep the following filters from being clogged, the sediment filter eliminates the biggest fragments, such as dirt, sand, and rust. 

Pre-Carbon Blocks

In order to block anything bigger than a grain of flour from going through, the pre-carbon filtration uses carbon called activated carbon. It also attracts and bonds with positively charged electrons to block the passage of chemical substances like chlorine and chloramines to the tertiary filter. 

Reverse Osmosis Membrane 

The removal of molecules larger than water, such as sodium, significant amounts of lead, dispersed minerals, and fluoride, is then accomplished by the process known as the reverse osmosis membrane. The water is then polished by post-carbon filtration and sent out for drinking purposes.

Why is Reverse Osmosis Important?

Reverse Osmosis is different from carbon filtering. It is very important to clean and purify the water. Reverse Osmosis can eliminate 99.9% of all impurities and particulates from water, or particles as fine as 0.001 micron. On the other hand, carbon filtration is unable to do so for impurities as small as 1 micron. 

It is always ideal to invest in a reverse osmosis filtering device to ensure that your water is devoid of pollutants because even though the city’s tap water may look clean when it departs from the city’s water plant, it might pick up a variety of substances or have a simply high level of total dissolved solids (TDS) as it flows.

What does a Reverse Osmosis System Remove?

Using the RO membrane, the system of reverse osmosis eliminates dissolved substances like arsenic and fluoride. For an extensive range of elimination, an RO plant also has sediment and chemical filtering. In an RO structure, the sediment filtration and carbon filters each extract different types of impurities from the water. It includes chlorine, unpleasant tastes and odours.

The Reverse osmosis system removes:

  • Fluoride 
  • Salt
  • Chlorine
  • Arsenic
  • Herbicides 
  • Pesticides
  • Organic Compounds
