Reverse osmosis (RO) is widely regarded as one of the most successful water filtering processes, producing clean, flavourful water. RO water purifier systems are utilized for a variety of purposes, including filtration for the whole household, faucets, aquariums and restaurants.

Whatever type of water you receive at your home, there is a Pureit water purifier - the best water purifier for every home that will meet your demands. You'll learn what reverse osmosis systems are, how they work, and what they're used for in the sections below along with the list of the top reverse osmosis systems available.

Reverse Osmosis - Definition

Reverse osmosis (RO) is a water purification technique that employs a semi-permeable membrane to eliminate impurities from water. This process is highly efficient in purifying drinking water, effectively eliminating dissolved salts, heavy metals, minerals, bacteria, viruses, and other harmful substances.

The reverse osmosis process involves applying pressure to propel water through a semi-permeable membrane with extremely small pores. These pores permit the passage of water molecules while capturing larger particles and impurities. Consequently, the purified water is separated from the impurities, resulting in the production of clean and safe drinking water.

Reverse osmosis finds extensive use in both residential and commercial applications. Many households opt for reverse osmosis to ensure access to clean and healthy drinking water, particularly in areas with subpar water quality or concerns regarding contaminants. Industries such as food and beverage processing, pharmaceutical manufacturing, and seawater desalination also widely employ RO systems.

What are osmosis and reverse osmosis?

Osmosis is a phenomenon where liquid water moves through a semipermeable membrane from a less concentrated solution to a more concentrated solution. Reverse osmosis, on the other hand, refers to the process of the solvent moving through a semipermeable membrane from a solution to the pure solvent, achieved by exerting excess pressure on the solution side.

How does RO or Reverse Osmosis work?

When pressure forces unfiltered water or feed water across a semipermeable membrane, reverse osmosis eliminates impurities. The position of small pores in a semipermeable membrane restricts pollutants while allowing water molecules to pass through. As water travels across the membrane via osmosis, it becomes more concentrated to achieve equilibrium on both sides. Reverse osmosis, on the other hand, prevents pollutants from entering the membrane's less concentrated side.

With high pressure, only the pure water can pass through the RO membrane in reverse osmosis purifiers leaving the impurities stuck in the RO membrane

Is reverse osmosis water beneficial to your health?

A reverse osmosis water system filters out dissolved impurities that are invisible to the naked eye but are capable of making us sick. Reverse Osmosis water removes heavy metals in water making it 100% safe for consumption. Drinking pure water from an RO water purifier helps in increasing the metabolism rate, improving the digestion process, and assisting in weight loss. Although it may eliminate few important minerals like calcium and magnesium from water, the RO water purifier’s water is still safe to drink.

 

Our bodies are 70% to 80% water, which keeps us hydrated, lubricates joints, and helps organs function properly. Minerals aren't required for those tasks. For your body to absorb enough mineral content to make a major effect, you'd have to drink a lot of water. Hence, it is important to buy an ideal water purifier for your home.

Is reverse osmosis environmentally friendly?

Most of the best water purifiers for homes are eco-friendly. Consumable water should be free from chemicals and other impurities. Utilizing RO is a more environmentally friendly option than using toxic chemicals. Pressure and specially constructed membrane systems remove dangerous contaminants, allowing water to safely re-enter the water cycle or even be reused in manufacturing. 

 

What is RO Water Purifier and how does it work?

To answer the question what is RO water purifier we first explained the process of RO in above paragraph, now coming to RO water purifier and its working system a major role is played by reverse osmosis process. 

So in short RO water purifier or reverse osmosis water purifier is India's most widely populated water purifier. RO purifier uses osmosis method in reverse to purify dissolved solids and other mineral waste from drinking water to make it safe for consumption. This is the most simplest answer to the question what is RO water purifier.

Bottled water vs RO water purifier

Despite the countless marketing initiatives that huge brands participate in, bottled water's main disadvantage is not only its source, but also that it is delivered in plastic bottles. Plastic is not biodegradable on its own, and when exposed to sunshine, it begins to mix with the water it contains.

 

This has serious health consequences. In terms of water filtration, a RO water purifier is quite effective. Because of its expanding popularity, some mineral water makers adopt this technology as well. Pureit’s RO + Mineral purifiers not only remove dangerous impurities from water, but also replace missing nutrients that our bodies require. Incase, you are wondering which water purifier is the best for your home, then it is the Pureit water filter series.

Stages of RO+UV water purifiers

A reverse osmosis system is centered on the RO membrane, along with additional types of filtration. All the best water purifiers for homes have three, four, or even six stages of filtration. A sediment filter and a carbon filter are the major filtration stages in the pre-RO water purification stage. Depending on whether water travels through them before or after passing through the membrane, the filters are referred to as prefilters or post-filters.

Pre-RO Filtration

A Sediment Filter and a Carbon Filter are commonly used in the Pre-RO filtration step. This is the first step in the RO water purifier process.

 

Sediment Filter (SF) – A sediment filter removes suspended particles such as dirt, dust, sand, and rust from your water supply. It improves the life of the Carbon Filter by removing fine and coarse particle pollutants.

 

Carbon Filter - The carbon filter, which is the second stage of the filtration process, removes dissolved chlorine, oil, colour, and odour. Organic contaminants, such as hazardous pesticides, are also removed by the filter. It also absorbs organic chemicals that give water a foul taste and odour.

 

Pureit incorporates a Mesh Filter to provide an additional layer of purification before the water is transferred onto the RO membrane. This filtration ensures that any leftover particle contaminants are removed.

 

The RO membrane is the heart of a RO water purifier.

Water is pushed through a RO membrane after passing through the above stages of pre-filtration. The RO membrane is a thin, semipermeable membrane with extremely small pores. The RO membrane's narrow size ensures that only filtered water flows through it, while all contaminants are rejected. The pump pressurizes the water to provide the appropriate pressure level for the RO membrane to filter it.

 

Being the best water purifier for home, Pureit ensures only purified water is pushed through the membrane with the aid of high water pressure, leaving dissolved salts, heavy metals, chemicals, pesticides, and microbiological pollutants on the membrane surface.

UV light

A UV light is incorporated with the RO water purifier, which supports the sterilization of microbes in the water by annihilating all dangerous microorganisms present. The high-powered UV radiation kills disease-causing germs by damaging their genetic core, preventing them from reproducing. The ultimate goal of a UV light is to eradicate 99.99 percent of hazardous germs from water, making it safe to drink.

 

Prefiltration is performed on the water before it enters a RO system. To remove sediment and chlorine that could clog or harm the RO membrane, prefiltration usually includes a carbon filter and a sediment filter. The water next passes over a reverse osmosis membrane, removing dissolved particles that are too tiny to be detected with an electron microscope.


Water goes from the filtration framework to the capacity tank, where it is stored until it is required. A RO framework channels water until the capacity tank is full, so, all things considered, it turns down. When you turn on your drinking water faucet, water from the storage tank passes through another postfilter, polishing the water before it reaches your faucet.

 

Post-RO filtration

 

The water flows through the post-carbon filter before being pumped into the storage tank. The filter removes any remaining impurities that pass through the membrane, making the water fully pure and safe to drink. Along with these filters, the Pureit water purifiers have a TDS controller, which aids in the retention of all-natural minerals in the purified water. Pureit Eco Range of RO water purifiers come with Eco Recovery Technology which also helps reduce the water wastage.

 

The method allows for the recovery of over 60% of water as purified water, resulting in less water waste. Furthermore, RO wastewater can be used for a variety of residential applications, including watering plants.

 

Ultra-violet Filter: A purification layer is added by an Ultraviolet filter after the water is passed through the RO membrane.Microorganisms such as bacteria, viruses, and parasites that may have survived RO filtration are inactivated by UV filtration.

 

Post RO Carbon Filter: This is usually the final stage of purification. It serves as the last filter, polisher, and enhancer of purified water's flavour.

 

A Micro-Filtration Membrane, which is a post-RO and UV stage, is included in Pureit water purifiers, ensuring that water is filtered not once, but three times.

 

Are you wondering which water purifier is best for a home that also has a detailed filtration process? Then, the answer is Pureit. Pureit's Advanced 7 stage RO+UV+MF purification system combines these steps to ensure that your drinking water is 100 percent safe and free of pollutants.

What type of water contaminants will be removed by reverse osmosis?

Reverse osmosis can remove 99 percent or more of dissolved salts (ions), particles, colloids, organics, microorganisms, and pyrogens from the feed water. Contaminants are rejected by a RO membrane based on their size and charge. Similarly, the higher the contaminant's ionic charge, the less probable it is to flow through the RO membrane, some of which are:

 

  • Lead
  • Mercury
  • Nitrates
  • Pesticides
  • Sediment
  • Sodium
  • Sulfates
  • Arsenic
  • Calcium
  • Chlorine
  • Dyes
  • Fluoride

Advantages of Reverse Osmosis

Reverse osmosis has a number of advantages as a water treatment method, including:

 

Total dissolved solids reduction: Reverse osmosis is one of the few water treatment methods that can claim to reduce total dissolved solids. RO water purifiers ensure that reverse osmosis is done more frequently than the few other treatment technologies that have this capability.

 

Alkalinity: The best RO water purifier for home ensures that the reverse osmosis eradicates the calcium and magnesium ions that contribute to hard water, and the carbonate ions that contribute to undesired alkalinity, from the water.
