Discover how reverse osmosis works, what it removes from drinking water, and why Hydro Balance restores minerals after purification.
Introduction
Every time you turn on the faucet, you trust that your water is clean enough to drink. But have you ever stopped to wonder what’s actually in your water?
Depending on where you live, your drinking water may contain dissolved minerals, chlorine, sediment, heavy metals, agricultural runoff, industrial chemicals, and even microscopic plastic particles. Municipal water treatment does an excellent job of making water safe to drink, but it doesn’t remove everything, and the taste can vary significantly from one community to another.
That’s why more homeowners and businesses are turning to reverse osmosis (RO), one of the most advanced water purification technologies available.
At Hydro Balance, reverse osmosis is at the heart of our purification process. We start by removing unwanted contaminants, then carefully restore naturally derived minerals to create clean, refreshing water with a balanced taste.
In this guide, we’ll explain how reverse osmosis works, what it removes, what it doesn’t remove, and why mineral restoration is an important final step.
What Is Reverse Osmosis?
Reverse osmosis (RO) is a water purification process that uses pressure to push water through a semipermeable membrane.
The membrane contains microscopic openings approximately 0.0001 microns in size.
To put that into perspective:
- A human hair is about 70 microns wide.
- Most bacteria are about 1 micron.
- Many viruses are much smaller than bacteria.
- An RO membrane is designed to reject many dissolved contaminants while allowing water molecules to pass through.
As water passes through the membrane, unwanted contaminants are separated and flushed away, leaving highly purified water behind.
This technology is trusted in:
- Hospitals
- Pharmaceutical manufacturing
- Food and beverage production
- Aquariums
- Laboratories
- Residential water systems
- Premium bottled water facilities
Why Do We Need Reverse Osmosis?
Although municipal water is regulated and treated to meet safety standards, it can still contain substances that affect taste, odor, or overall water quality.
These may include:
- Chlorine
- Chloramine
- Heavy metals
- Dissolved salts
- Agricultural runoff
- Industrial pollutants
- PFAS (“forever chemicals”)
- Sediment
- Rust from aging pipes
- Excess minerals that cause hard water
Reverse osmosis provides an additional layer of purification beyond traditional municipal treatment.
What Does Reverse Osmosis Remove?
One of the biggest advantages of reverse osmosis is its ability to remove a wide range of dissolved contaminants.
Heavy Metals
RO membranes are highly effective at reducing many heavy metals, including:
- Lead
- Mercury
- Arsenic
- Cadmium
- Chromium
- Copper
- Barium
These contaminants may enter water supplies through old plumbing, industrial activities, mining, or naturally occurring geological deposits.
PFAS (Forever Chemicals)
PFAS are synthetic chemicals that have been used in products like non-stick cookware, waterproof fabrics, firefighting foam, and industrial manufacturing.
Because they persist in the environment, they’re often referred to as “forever chemicals.”
Reverse osmosis is considered one of the most effective technologies available for reducing many PFAS compounds.
Fluoride
Many public water systems add fluoride to support dental health.
A reverse osmosis system can typically remove 90–99% of fluoride, depending on the water chemistry and system design.
Nitrates
Nitrates often originate from:
- Fertilizers
- Animal agriculture
- Septic systems
- Stormwater runoff
High nitrate concentrations can be particularly concerning for infants and young children.
RO systems are highly effective at reducing nitrates.
Sodium
Many people are surprised to learn that sodium is naturally present in many water supplies.
Reverse osmosis significantly reduces sodium levels, making it a popular option for those looking to reduce sodium in drinking water.
Dissolved Salts
Reverse osmosis removes many dissolved salts that contribute to high Total Dissolved Solids (TDS), including:
- Calcium
- Magnesium
- Potassium
- Sulfates
- Chlorides
Most systems reduce TDS by 95–99%.
Microplastics
Research has found microscopic plastic particles in rivers, lakes, bottled water, and tap water around the world.
Because of its extremely fine membrane, reverse osmosis effectively removes microplastics from drinking water.
Sediment
RO systems also remove:
- Sand
- Dirt
- Rust particles
- Silt
- Scale
These particles can affect both taste and appearance.
Many Bacteria and Viruses
When operating correctly, an intact RO membrane rejects many bacteria and viruses because they are larger than the membrane’s microscopic pores.
For added protection, many commercial systems pair reverse osmosis with UV disinfection, ozone treatment, or other sanitation methods.
What Doesn’t Reverse Osmosis Remove?
Although RO is one of the most comprehensive purification methods available, the membrane isn’t designed to remove every type of contaminant on its own.
A complete RO system typically includes pre-filters and post-filters to improve overall performance.
Activated Carbon Removes:
- Chlorine
- Chloramine (depending on the carbon media used)
- Many volatile organic compounds (VOCs)
- Unpleasant tastes
- Unpleasant odors
Carbon filtration also protects the RO membrane from chlorine damage.
Sediment Filters Remove:
- Dirt
- Sand
- Rust
- Larger particles
These filters help extend the life of the RO membrane.
Why Reverse Osmosis Removes Minerals Too
One common question is:
“If reverse osmosis removes contaminants, does it also remove beneficial minerals?”
Yes.
Because the membrane is so effective, it removes most dissolved minerals—including:
- Calcium
- Magnesium
- Potassium
This results in exceptionally pure water with a very low TDS.
While this water is safe to drink in low amount, some people notice that it tastes “flat” because the naturally occurring minerals that contribute to flavor have been removed.
Why Hydro Balance Restores Minerals
At Hydro Balance, we believe the best drinking water combines purity with balance.
That’s why we don’t stop after reverse osmosis.
After purification, we restore carefully selected, naturally derived minerals to create water that is:
- Crisp
- Refreshing
- Consistent
- Great tasting
This mineral restoration provides a balanced water profile while preserving the benefits of advanced purification.
Why Does Mineral Water Taste Better?
Think about your favorite spring water.
Its distinctive taste comes largely from the minerals it naturally picks up while traveling through underground rock formations.
Ultra-pure water lacks those dissolved minerals, which can make it taste bland.
Restoring minerals creates a smoother, fresher taste that many people prefer.
Why Hydro Balance Uses Reverse Osmosis
Every gallon of Hydro Balance water goes through a carefully controlled purification process.
Our system is designed to:
- Remove unwanted contaminants.
- Produce consistently high-quality water.
- Restore naturally derived minerals.
- Deliver fresh, great-tasting water every time.
Rather than relying on the natural variations found in untreated water sources, we create consistency in every refill.
Frequently Asked Questions
