Does reverse osmosis really filter the water systems?

22 May 2024

In a world where clean drinking water is essential for good health, reverse osmosis water filters have become a popular choice. You may be surprised to learn that nearly 80% of Indian households understand the importance of purified water and have implemented systems to ensure they have access to the highest-quality supply around the clock.

Whenever you travel, you’re often advised to buy mineral water instead of regular water to safeguard your health. The process behind ‘mineral water’ is carried out by reverse osmosis filter systems. But do they really filter the water systems as efficiently as claimed? Let’s unravel the science and benefits behind reverse osmosis (RO) and see if it’s the right solution for your home.

What is reverse osmosis?

Reverse osmosis (RO) is a process that uses a semipermeable membrane to remove impurities and contaminants from water. It works by applying pressure to the contaminated water, forcing it through the membrane while leaving behind larger molecules and particles. This results in clean, purified water on one side of the membrane, and concentrated waste on the other.

The semipermeable membrane used in RO filters has tiny pores that only allow pure water molecules to pass through, effectively blocking out impurities and contaminants like bacteria, viruses, dissolved solids, and chemicals. This makes reverse osmosis one of the most effective methods for purifying water.

How does reverse osmosis work?

To understand reverse osmosis, it’s crucial to first grasp the concept of osmosis. Osmosis is a natural process where water molecules move from a region of lower solute concentration to a region of higher solute concentration, aiming to balance solute levels on both sides of a membrane.

Osmosis

Osmosis is fundamental to many biological processes. For instance, it helps plants absorb water from the soil and allows cells in our body to maintain proper hydration. In osmosis, the solvent (water) naturally flows to equalize concentrations, but this process can be reversed with external pressure.

Reverse Osmosis

In reverse osmosis, external pressure is applied to counteract the natural osmotic pressure, forcing water molecules through a semipermeable membrane. This membrane allows only water molecules to pass through while blocking contaminants such as salts, bacteria, and other impurities.

Why RO system is beneficial?

Reverse osmosis systems offer numerous benefits that make them an attractive option for those seeking clean and safe drinking water. Here are some of the key advantages: 

  • Effective Contaminant Removal: RO systems can remove up to 99% of contaminants, including heavy metals, pathogens, and chemicals. 
  • Improved Taste and Odor: By eliminating impurities, RO systems enhance the taste and odor of drinking water. 
  • Eco-Friendly: RO water reduces the need for bottled water, lowering plastic waste and environmental impact. 
  • RO plant produces a healthy, fresh, and enormous water supply 
  • RO technology is fully automated 
  • RO water systems are cost-effective for any end-user 
  • Reverse osmosis water Plants do not use electricity or require a power source and are easy to maintain 
  • RO water plant mitigates additional water delivery service or purchasing of water bottles 
  • Reverse Osmosis filter system is relatively easy to install 

How does RO water filter system work?

An RO water filter system utilizes a multi-stage filtration process to ensure thorough purification. Each stage targets specific types of contaminants, resulting in clean and safe drinking water.

This advanced technology has helped the usual water treatment process change lives with its easy installation and implementation. The RO water plant’s history dates to the late 1970s by the municipalities, and today, they have made their name and are here to stay in every household, with new upgrades each passing day.

The 4-stage process of Reverse Osmosis water purification

Beyond our naked eye, we can unfortunately not see minute organisms that can harm our health by floating in the water. Hence, the RO system involves the form of filters and an RO membrane, such as sediment or carbon filters, where the impurities are filtered and let the way to flow out and go down the drain, leaving us clean, pure water to be consumed or used for other daily chores.  

  1. Sediment Filter 
    The first stage involves a sediment filter that removes larger particles such as dirt, rust, and silt. This step is crucial in protecting the subsequent filters and the RO membrane from clogging and damage. 
  2. Carbon Filter 
    Next, the water passes through a carbon filter that targets chlorine, volatile organic compounds (VOCs), and other chemicals. This stage not only improves the water’s taste and odor but also protects the RO membrane from chlorine damage. 
  3. Reverse Osmosis Membrane 
    At the heart of the system lies the reverse osmosis membrane. Under high pressure, water molecules are forced through this semipermeable membrane, which effectively blocks most contaminants, including heavy metals, bacteria, and viruses. 
  4. Polishing Filter 
    Finally, a polishing filter (often another carbon filter) provides the last touch of purification, ensuring any remaining impurities are removed and the water is crisp and clean. 

How to maintain a longer expectancy of a RO plant?

Maintaining an RO system is essential for its longevity and efficiency. Regular upkeep ensures the system continues to deliver high-quality water. Here are some maintenance tips: 

  • Regular Filter Replacement: Filters should be replaced as per manufacturer recommendations to prevent clogging and ensure optimal performance. 
  • Sanitize the System: Periodic sanitation helps eliminate any microbial buildup within the system. 
  • Check for Leaks: Regularly inspect the system for leaks or damages to avoid water wastage and potential system failure. 

What impurities does RO Water Plant eradicate?

RO system can remove up to 99 per cent of 65 different contaminants. 

  • Dissolved salts like sodium, potassium, calcium, magnesium, chloride, and sulphates.
  • Chemicals include chlorine and chloramines, fluoride, pesticides and herbicides, and volatile organic compounds (e.g., benzene and toluene).
  • Heavy metals, including lead, chromium, and copper.
  • Biological contaminants, such as bacteria, viruses, and protozoa.
  • Particulate matter like sediment, silt, and other suspended solids.
  • Pharmaceuticals such as hormones and antibiotics.
  • Radiological elements such as radium and uranium.

Key takeaways

Reverse osmosis is a powerful and efficient method for purifying water, making it an ideal choice for households looking to ensure their water is free from contaminants. By understanding how reverse osmosis works and the benefits it offers, you can make an informed decision about whether an RO system is right for you. 

For those considering an RO system, remember that regular maintenance is key to its longevity and effectiveness. With proper care, an RO system can provide clean, safe, and great-tasting water for years to come.
