Water is a fundamental part of our daily lives, and having clean water is essential for our health and well-being.

In this article, we'll break down everything you need to know about reverse osmosis filtration.

We'll cover the benefits and drawbacks, when it's the best option, when it might not be, and why Glow Logic's water filters are a much more practical and affordable alternative. Let's get into it!

So, What is Reverse Osmosis?

Reverse osmosis is a water purification process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. The contaminants are left behind, resulting in highly purified water.

A reverse osmosis system typically includes several stages of filtration, including pre-filters, the reverse osmosis membrane, and post-filters, to ensure thorough purification.

Reverse osmosis is known for its ability to remove a wide range of impurities, making it one of the most effective water filtration methods available. However, it's important to understand the full picture before deciding if it's the right choice for your home.

How Does Reverse Osmosis Filter Work?

To get a better grasp of the process, let's break down the key stages of reverse osmosis water system:

1. Pre-Filtration: Water first passes through a pre-filter, which removes larger particles like sediment and chlorine that could damage the reverse osmosis membrane.
2. Reverse Osmosis Membrane: The water then moves through the semipermeable membrane, which filters out the majority of dissolved contaminants, leaving only purified water.
3. Post-Filtration: After passing through the reverse osmosis membrane, the water goes through a post-filter to remove any remaining impurities and enhance the taste.

Positives of Reverse Osmosis Filtration

Reverse osmosis filtration has some clear benefits:

1. Contaminant Removal: It effectively removes a wide range of contaminants, including chlorine, heavy metals, nitrates, fluoride, and more. This makes the water safe for drinking and other uses.
   
   
2. Improved Taste and Odor: By removing impurities, reverse osmosis system water often tastes and smells better than unfiltered water, making it more enjoyable to drink and use in cooking.
   
   
3. Suitable for Various Applications: Reverse osmosis systems can be used for residential, commercial, and industrial purposes where high-purity water is needed. This versatility is one of the reasons why it's so popular.

Negatives of Reverse Osmosis Filtration

Despite its benefits, there are several downsides to consider:

1. Waste Water:

High Waste Ratio: Reverse osmosis systems produce a significant amount of wastewater. For every litre of purified water, several litres can be wasted. This is not only inefficient but also environmentally unfriendly.

Environmental Impact: The large volume of wastewater can put a strain on local water resources and contribute to water scarcity, especially in areas already facing water shortages.

2. Removes Essential Minerals:

Loss of Beneficial Minerals: While reverse osmosis removes harmful contaminants, it also strips away beneficial minerals like calcium and magnesium. These minerals are essential for maintaining good health and contribute to the taste of water.

Health Concerns: The lack of essential minerals in reverse osmosis water can lead to mineral deficiencies if it is the primary source of drinking water. Some health experts recommend remineralising reverse osmosis water before consumption.

3. High Cost:

Initial Investment: Reverse osmosis systems are expensive to purchase and install, with costs ranging from a few hundred to several thousand dollars, depending on the system's capacity and features.

Ongoing Maintenance: Regular maintenance, including filter and membrane replacements, can be costly. These components need to be replaced periodically to maintain the system's efficiency and effectiveness. Annual filter changes can easily be the better part of one thousand dollars per year when you factor in labour.

4. Water Pressure Requirements:

Need for High Pressure: Reverse osmosis systems require high water pressure to function effectively. If your home's water pressure is low, you might need to install a booster pump, adding to the system's complexity and cost.

High Potential for Reduced Flow: In homes with fluctuating water pressure, the reverse osmosis system's performance can be inconsistent, leading to reduced water flow and longer filtration times.

5. Slow Filtration Process:

Time-Consuming: The process of reverse osmosis is relatively slow compared to other filtration methods. Producing a litre of purified water can take several hours, which can be inconvenient for daily use.

Storage Needs: Due to the slow filtration rate, many reverse osmosis systems come with a storage tank to ensure a steady supply of purified water. This tank can take up valuable space under your sink or in your utility area.

6. Complex Installation and Maintenance:

Professional Installation: Reverse osmosis systems can be complicated to install, often requiring professional assistance. This adds to the initial cost as most of us aren't trained to deal with the complexity.

Regular Maintenance: Proper maintenance is crucial for reverse osmosis unit to function effectively. This includes periodic cleaning, filter replacements, and membrane checks, which can be time-consuming and require technical knowledge.

7. Potential for Contaminant Build-Up:

Membrane Fouling: If not maintained properly, contaminants can build up on the reverse osmosis membrane, reducing its efficiency and potentially contaminating the water. This can lead to higher maintenance costs and more frequent membrane replacements.

System Downtime: When the membrane becomes fouled, the system may need to be shut down for cleaning or replacement, leading to periods where purified water is unavailable.

8. Flat Taste:

Lack of Minerals: Some people find that reverse osmosis water tastes flat because it lacks natural minerals that enhance the taste of water. This can make it less appealing to drink.

Remineralisation Needs: To improve the taste, some users choose to add remineralisation filters to their reverse osmosis systems, which add back essential minerals. This, however, adds to the system's complexity and cost.

9. High Water Usage for Showers:

Enormous Water Bills: Because reverse osmosis systems waste a lot of water in the purification process, using reverse osmosis filtered water for showers can result in extremely expensive water bills. This high water usage makes it impractical for everyday activities like showering.

10. Impractical for Everyday Use Beyond Drinking:

High Water Volume Needs: Most household water use is for bathing and washing clothes. A shower can consume 200-500 litres of water. Because the reverse osmosis filtration process is so slow, trying to use reverse osmosis filtered water for showers would require a large storage tank and a re-pressurisation system to accumulate enough water. This setup would only provide cold water, as hot water tanks are not compatible with reverse osmosis water due to the high potential for corrosion issues.

Space and Cost Concerns: Installing an reverse osmosis system for shower use would require significant space for the equipment and a high installation cost. Ideally, it should also be installed on a new house build, otherwise the walls and floor will need to be cut into to add the required plumbing, which will significantly add to the overall expense. Given these factors, it’s impractical to use reverse osmosis water for showers and other high-volume applications.

When is Reverse Osmosis Recommended?

Reverse osmosis filtration is recommended in situations with:

High Levels of Contamination: Areas with less than ideal water quality benefit from reverse osmosis systems due to their high contaminant removal efficiency.

Poor Water Quality: If the water supply is known to have issues with pollutants, reverse osmosis can provide a much-needed solution. However, reverse osmosis is not a treatment process, and instead is termed as a polishing process. This means it can only make decent water better, not completely transform terrible water into something good.

Specific Health Concerns: Individuals who have specific health concerns or sensitivities may find reverse osmosis systems beneficial for providing pure water. In such cases, installing a reverse osmosis filter system in your home makes complete sense. 

Industrial or Commercial Applications: Reverse osmosis systems are often used in industries where high-purity water is essential, such as in pharmaceuticals or food and beverage production.

When is Reverse Osmosis Not Recommended?

Reverse osmosis filtration may not be suitable for:

Areas with Low Water Pressure: Reverse osmosis systems need high water pressure to function effectively, which can be a limiting factor in some homes.

Situations Where Water Conservation is a Priority: Due to the significant amount of wastewater produced, reverse osmosis is not ideal for areas where water conservation is important.

Homes with Relatively Good Water Quality: In areas where the water quality is already good, the high cost and maintenance of reverse osmosis systems is hard to justify, especially when you can get such good results from conventional water filters (like ours).

Households Looking for Cost-Effective Solutions: For many households, the high initial and ongoing costs of reverse osmosis systems make them less attractive compared to other filtration options.

Reverse Osmosis Filtration is Not Environmentally Friendly

One of the significant concerns with reverse osmosis is its environmental impact:

Large Amounts of Wastewater Production: The large volume of wastewater generated during the filtration process can be a significant drawback, especially in areas where water conservation is essential. For every litre of purified water, several litres of wastewater are produced.

High Energy Consumption: The high energy consumption required for reverse osmosis systems can contribute to a larger carbon footprint. This is especially true for systems that require booster pumps to maintain adequate water pressure.

Huge Demand on Water Supplies: The increased demand for water to operate reverse osmosis systems can put a strain on local water resources, exacerbating issues in regions with limited water availability.
