While both have their benefits, understanding the pros and cons of each can help you make the best decision for your facility. In this blog post, we’ll explore the differences between UV and RO water treatment so you can make an informed decision for your business. Stay tuned!
We all know that drinking tap water transported through old and corroded pipes comes from far away. In addition, some minerals and salts that exceed drinking water standards can be present in well water. Furthermore, toxic chemicals and high TDS (total dissolved solids) values are possible in groundwater-dependent regions. As a result, when it comes to your family or business requirements, you’ll need to use the appropriate water purifier.
When it comes to employees’ health, many businesses and multinational organizations use a variety of wellness program methods. They have gyms and free memberships, organize health fairs, and offer flu vaccinations. However, the most important thing any business can do is install a commercial water purifier in their workplace. This will be the greatest benefit for the workers.
Reverse Osmosis Vs UV
RO (reverse osmosis) and UV (ultraviolet) are the most common types of commercial water purifiers on the market. Let’s learn more about Reverse Osmosis Vs UV water treatment systems.
Reverse Osmosis (RO) Water Purifier System
Reverse osmosis removes undesirable elements from water by forcing it through a semi-permeable membrane under pressure. To provide clean drinking water, the higher concentrated side (more pollutants) of the RO membrane pulls water from the less concentrated side (less pollutants). Permeate is the water that results from the separation of salts and minerals. The saline or mineral-rich portion is known as reject or waste.
A semi-permeable membrane has tiny pores that prevent contaminants from passing through but allow water molecules to pass through. When water moves across a membrane in osmosis, it becomes more concentrated on both sides as a result of osmosis. Reverse osmosis, on the other hand, prevents pollutants from entering the less concentrated side of the membrane. When pressure is applied to a quantity of saltwater, for example, only clean water passes through when the salt is left behind.
Advantages of Reverse Osmosis
The most significant characteristic and advantage of commercial RO systems is that they can remove up to 95% TDS. It distinguishes out from the other purification methods because it has EPA certification (Environmental Protection Agency) as one of the most effective treatments for removing dissolved impurities in water that are difficult to filter using conventional filtration technology. The World Health Organization (WHO) has studied the harmful effects of heavy metals on the body. It is possible that arsenic causes skin cancer and a variety of other malignancies as well as skin abnormalities such as pigmentation changes and hyperkeratosis. Cadmium ingestion might result in kidney damage, whereas Lead consumption can induce neurological damage.
All of the previously mentioned heavy metals may be eliminated by a commercial RO water purifier, which improves the water’s flavor by removing all of the dissolved impurities. RO water purifiers transform saltwater into drinkable water by removing pollutants from it in regions that rely on groundwater with high TDS and hardness levels.
Disadvantages of Reverse Osmosis (RO)
Over time, the small pores of a commercial RO membrane can get clogged. As a result, a pre-filter is needed in the purifying system to preserve the membrane. Over time, RO membranes develop a film of microorganisms on them that causes biofouling on the surface. The bacteria that adhere to its surface gnaw into the membrane pores, allowing them to expand in size. The membrane pores become larger, allowing live bacteria on the other side of the barrier to cross over and acquire pure permeate. RO membranes do not remove all organic impurities from drinking water.
Organic contaminants in the RO membrane self-defeat the process of purification, which contaminates the water purified by the RO unit. This is one of the biggest challenges with RO membranes. Endpoint purification necessitates disinfection after removal of the RO membrane to reduce this hazard. In certain situations, UV may be required.
Another significant disadvantage of RO purification systems is the waste of water. The majority of commercial RO purification systems recover only 25% of water, with the remaining amount dissipating into the sink. As a result, deciding when and how to use an RO system becomes a difficult issue.
By removing almost 90% of the TDS in water, RO membranes reduce the TDS content in water by a huge amount. When TDS levels following an RO purification drop below acceptable limits, not only is the water removed of essential minerals, but it may also have a harsh taste. This isn’t beneficial to your health in the long term.
UV Water Purifier System
Commercial UV water purification systems use UV (Ultraviolet) radiation to destroy pathogenic bacteria in water, making it safe for drinking. This technique can destroy dangerous germs and may be boosted by pre-filtering. Because they eliminate all hazardous organisms from the water without altering its flavor, commercial UV water purifiers are health beneficial. The commercial UV water purifier destroys harmful bacteria by exposing them to UV radiation. It employs a UV light source that is set up in a chamber with a closed design such that when water flows through it, UV light penetrates the cells of microorganisms and renders their reproduction capability ineffective.
Advantages of UV Purification
- Stainless Steel purification chamber
- Quartz glass technology for superior UV transmission
- Comes with Advanced Filtration System
- Reliable and consistent UV disinfection efficiency
- High quality and affordability
- The process is quick and simple. Compact units that require minimal room.
- Easily adaptable to varied site conditions.
Disadvantages of a UV Water Purifier
- UV water purifiers destroy germs and viruses, but they do not remove dissolved impurities such as pesticides, rust, arsenic, fluoride, and other pollutants. It does not turn hard water into sweet, soft water.
- Water can no longer be disinfected effectively when suspended impurities are present. When water is muddy, it must first pass through a good filter before going through the UV water purifier.
- To operate a UV system, electricity is required.

Conclusion
So, what’s the verdict? Reverse Osmosis Vs UV for your water treatment system? If you have a high-quality water source with low levels of contaminants, then an RO system may work for you. However, if your water contains higher levels of pollutants or other impurities, then adding a UV disinfection unit can help ensure that your water is safe to drink and meet regulatory standards.
Advantages of Buying Directly from a Manufacturer
In previous times, manufacturers encountered obstacles when it came to directly reaching consumers due to financial limitations. This led to the introduction of distributors, acting as intermediaries between manufacturers and consumers. These middlemen, commonly known
