Businesses need reliable access to good-quality drinking water. But choosing the right filtration system can be difficult when different technologies remove different types of impurities.
Reverse osmosis (RO) is one option for facilities that want more extensive water treatment than basic filtration. It removes impurities by applying pressure to force water through a semi-permeable membrane, leaving many dissolved particles behind before it reaches your point of dispensation.
The benefits of reverse osmosis water can include reduced dissolved solids, improved taste, and less dependence on bottled water. However, RO has factors worth considering, including water efficiency, maintenance, and system capacity.
So, what does RO actually offer, and when does it make sense for a commercial facility? This blog explores the reasons why.
What Is Reverse Osmosis Water?
Reverse osmosis water is water that has passed through a reverse osmosis membrane during purification. The membrane lets water pass through while blocking many dissolved substances.
In a typical RO process, incoming water first passes through pre-filtration stages. It then reaches the RO membrane, where pressure separates treated water from a concentrated reject stream. Additional filtration or treatment may follow before the water is dispensed.
The exact performance depends on the system, membrane, source-water conditions, and certified reduction claims. NSF/ANSI 58 includes testing requirements for RO systems, including TDS reduction, efficiency, recovery, and specific contaminant-reduction claims.
This is why businesses should look beyond the term “RO” when comparing systems. The important questions are what the system is certified to reduce, how much water it can produce, and whether its capacity matches the facility’s demand.
What Are the Benefits of Reverse Osmosis Water?
The main advantages of reverse osmosis water come from the membrane’s ability to reduce many dissolved substances that simpler filtration methods may not address to the same extent.
1. Reduces Dissolved Contaminants
RO can reduce a wide range of dissolved substances, depending on the specific system and its verified performance.
NSF/ANSI 58 includes optional testing for claims involving contaminants such as lead, arsenic, nitrate/nitrite, fluoride, copper, VOCs, and others. A system should only be credited with a specific contaminant-reduction claim when that performance has been verified for the product.
For a business, this can provide a more targeted approach to water treatment when source-water quality is a concern.
2. Improves Taste and Odor
RO systems often work alongside carbon filtration, which can reduce substances that affect taste and odor.
Removing or reducing certain dissolved substances can make water taste cleaner. This can also matter in offices where employees use filtered water for coffee, tea, and other beverages throughout the day.
3. Reduces Total Dissolved Solids
TDS, or total dissolved solids, refers to the combined concentration of dissolved substances in water.
RO membranes are designed to reduce TDS. In fact, TDS reduction is one of the performance areas addressed under NSF/ANSI 58.
Lower TDS does not automatically mean water is safer or better for every application. The right treatment depends on what is present in the source water and what the facility needs the water to do.
4. Reduces Dependence on Bottled Water
A bottleless system connected to an existing water supply can reduce the need for bottled water.
Instead of ordering, storing, lifting, and replacing large water containers, employees can access treated water directly from a dispenser. This can simplify workplace hydration and reduce the operational work associated with bottled deliveries.
Premium Pure Water connects its commercial systems directly to a building’s municipal water supply, providing purified water on demand without bottle storage or delivery management.
5. Supports Beverage and Food-Service Applications
Treated water can be useful anywhere water quality affects the drinking or beverage experience.
Offices may use it for coffee and tea. Hotels, cafeterias, and other hospitality environments may also use treated water as part of their beverage service.
The suitability of RO depends on the application. Businesses should consider source-water quality, equipment requirements, and whether the system’s treatment level matches the intended use.
6. Can Reduce Plastic Waste
A bottleless RO system can reduce the need for single-use bottled water because it treats and dispenses water at the point of use.
The environmental picture is more complicated when looking at RO itself. RO creates a reject-water stream during treatment. The EPA notes that typical point-of-use RO systems can send five gallons or more of reject water down the drain for every gallon of treated water produced, although more efficient systems can perform better.
For businesses, the better approach is to consider whether the selected system provides the needed treatment while using water efficiently.
How Does Reverse Osmosis Water Compare With Standard Water Filtration?
RO and carbon filtration do different jobs. Carbon filtration is commonly used to improve taste and odor and reduce certain contaminants. RO adds membrane-based treatment that can reduce many dissolved substances and TDS.
| Factor | Reverse Osmosis | Standard Carbon Filtration |
| Main process | Semi-permeable membrane | Adsorption through carbon |
| TDS reduction | Yes | Generally limited |
| Chlorine reduction | Can be part of the treatment system | Common application |
| Dissolved salts | Can reduce many | Generally limited |
| Mineral reduction | Can reduce minerals | Generally retains many minerals |
| Reject water | Yes | Typically no RO reject stream |
| Best suited for | Broader dissolved-contaminant reduction | Taste, odor, and targeted filtration |
Neither technology is automatically right for every facility. A detailed comparison of reverse osmosis vs. carbon filtration will help you understand what better suits your facility’s needs.
A business should start with its source-water quality and treatment goals. Premium Pure Water also offers both reverse osmosis water filtration and carbon filtration configurations, allowing the treatment approach to be matched to the facility’s needs.
Is Reverse Osmosis Water Good for Offices?
It can be a practical choice for offices that want more extensive water treatment and convenient access to purified drinking water.
A reverse osmosis water system in an office can be particularly useful when:
- Employees regularly use the dispenser throughout the day.
- The facility wants to reduce reliance on bottled water.
- Water taste or dissolved substances are a concern.
- The office needs a point-of-use treatment system.
- The business wants to combine filtration with hot, cold, or ambient dispensing.
- The facility has enough water demand to justify a commercial system.
The system should also match the size of the workplace. A small office with moderate demand has different requirements from a large corporate facility with hundreds of employees.
For example, Premium Pure Water’s WL30 Water Dispenser can be configured with five-stage RO or four-stage micro-filtration and is designed for up to 35 users.
This illustrates why capacity matters. A system should be selected based on expected usage, available space, dispensing needs, and water-treatment requirements rather than the filtration technology alone.
Are There Any Disadvantages of Reverse Osmosis?
Yes. Understanding the limitations is an important part of choosing a commercial system.
Wastewater During the RO Process
RO creates a concentrated reject stream as part of purification. The amount varies by system design and operating conditions.
The EPA recommends considering water efficiency when selecting an RO system and notes that WaterSense-labeled systems meet defined performance and efficiency criteria.
Reduction of Naturally Occurring Minerals
RO can reduce minerals such as calcium and magnesium along with other dissolved substances.
This may affect taste for some users. Some systems address this with remineralization technology. Premium Pure Water offers systems with mineral add-back technology designed to restore calcium and magnesium after RO treatment.
Ongoing Maintenance Requirements
Filters, membranes, and other components need appropriate servicing to maintain performance.
Commercial systems also need maintenance plans that match their usage levels. High-traffic facilities may have different service requirements from small offices.
Not Every Business Needs RO
RO is a treatment option, not a universal answer.
The right solution depends on incoming water quality, contaminants of concern, daily demand, available plumbing, space, dispensing requirements, and operating priorities.
How Do You Choose a Commercial Reverse Osmosis Water System?
Choosing a commercial RO system requires more than comparing filter counts. Start by understanding what your facility needs from its water system.
1. Evaluate the Source Water
Know what is in your incoming water. Water testing can help identify contaminants or dissolved substances that need attention.
2. Estimate Daily and Peak Demand
Consider the number of employees, guests, customers, or other users.
Also think about peak periods. An office may have moderate demand throughout the day, while a hotel, airport, manufacturing facility, or cafeteria can experience sudden increases in usage.
3. Check Available Space
Commercial dispensers come in different formats.
A countertop unit may work well where floor space is limited. A freestanding system may be more appropriate for a larger breakroom or high-traffic area.
4. Compare Filtration and Performance Claims
Look beyond general statements such as “advanced filtration.”
Check:
- What contaminants has the system been tested to reduce?
- What is its production capacity?
- What is its recovery or efficiency?
- What maintenance does it require?
- Does it have relevant certifications?
NSF/ANSI 58 is a useful reference when evaluating certified RO performance because it addresses TDS reduction, efficiency, recovery, and specific contaminant-reduction claims.
5. Consider Dispensing Needs
Think about whether your facility needs:
- Cold water
- Hot water
- Ambient water
- Ice
- Sparkling water
- Touchless dispensing
Premium Pure Water offers several commercial configurations. Its i14 Combination Ice & Water Dispenser, for example, combines hot, cold, and ambient water with ice and reverse osmosis support, and it’s designed for up to 50 users.
Why Choose a Bottleless RO Water Dispenser?
A bottleless RO dispenser combines water treatment with point-of-use access. That can make sense for businesses that want purified water without managing recurring bottle deliveries.
The biggest practical difference is the way the water reaches the user.
With bottled water, a business has to manage:
- Deliveries
- Bottle storage
- Empty containers
- Manual handling
- Inventory
A bottleless system connects directly to the building’s water supply and treats water as it is needed.
For smaller workplaces, a compact RO-enabled dispenser such as the WL30 can provide a practical solution. Higher-demand facilities can consider larger systems such as the WL50 Commercial Water Dispenser or XL1Touchscreen Water Dispenser, depending on their water demand and configuration.
This approach can also support purified water for offices without dedicating storage space to bottled water.
For businesses, the goal is to select a system that balances water quality, capacity, convenience, maintenance, and water efficiency.
Making the Right Choice for Better-Treated Water
The benefits of reverse osmosis water go beyond removing dissolved substances. For commercial facilities, RO can provide a practical way to improve water treatment while supporting convenient, bottleless access to drinking water.
However, choosing an RO system requires a closer look at source-water quality, capacity, efficiency, maintenance, and dispensing needs. A well-matched system can provide reliable treated water without adding the storage and delivery work associated with bottled water.
Premium Pure Water offers commercial bottleless dispensers with RO configurations for different workplace requirements, from smaller offices to high-demand facilities. The right setup depends on your users, water quality, available space, and daily demand.
Understanding these factors can help you make a more informed decision about the benefits of reverse osmosis water and whether a bottleless RO solution fits your facility.
