Introduction
A. O. Smith RO Water Purifier uses one of the latest technologies that is used in
water purification process. A. O. Smith RO Water Purifier works under the principle
of RO (Reverse Osmosis) technology which is found to be one of the most effective
process. In this process, water under pressure is passed through a semi-permeable
membrane. Purified water is collected for drinking in a storage tank and impurities in
the water are flushed to the drain.
Why water purification is important?
Water purification, today is essential due to the presence of harmful contaminants
present in the water supply. Rapid urbanisation and speedy industrial growth have led to
significant pollutants and contaminants being found in the water supply. Below is a list
of some of the harmful contaminants found today in the water supply which if
consumed in excess can be detrimental to human health.
• TDS (Total Dissolved Solids) like Nitrates, Chlorides, Sulphates etc.
• Pesticides and VOC (Volatile Organic Compounds).
• Heavy metals like Mercury, Arsenic, Lead, Chromium, Cadmium etc., imbalanced pH.
• Microorganisms such as pathogenic bacteria, virus, protozoa and cysts.
A. O. Smith RO Water Purifier removes excessive TDS (Total Dissolved Solids) in water
by more than 95%. A. O. Smith RO Water Purifier reduces heavy metals, removes
pathogens and balances the pH value. By this, it ensures you safe and great tasting
water.
How does A. O. Smith RO Water Purifier work?
A. O. Smith RO Water Purifier has 7 stages of purification system, wherein the water
is passed through the various stages and progressively filtered to get purified water
which is stored in the inbuilt storage tank.
Stage 1 – Pre-filter
The Pre-filter is used to remove physical contaminants such as dirt, dust, soil
particles, turbidity present in the water. This improves the life of the SCB filter
TM
Stage 2 and Stage 3 – SCB filter
This is a dual filter (Sediment and Carbon Block) where Sediment filter first removes
fine and coarse physical contaminants present in the water. Then water is passed
through Carbon Block, which reduces harmful chemicals like pesticides, volatile
organic compounds, residual chlorine etc. It also adsorbs bad taste and odour
causing organic compounds from water.
TM
Stage 4 – ART
(Advance Recovery Technology)
The ART is scale control media which conditions the water to reduce scaling
potential in water.

Stage 5 – RO (Reverse Osmosis) membrane
RO membrane contains semi-permeable membrane wherein the water is passed
through the semi-permeable membrane to remove TDS (Total Dissolved Solids) and
heavy metals like mercury, arsenic, lead, chromium, cadmium etc. It also removes
microorganisms like bacteria, virus, protozoa and cysts.
Stage 6 and Stage 7 – SCM-TECH
™ (Silver Activated Post Carbon and MIN-TECH)
This filter is the combination of Silver Activated Post Carbon and MIN-TECH
(Mineraliser Technology). Silver Activated Post Carbon acts as polisher and enhances
the taste of water. MIN-TECH contains Calcium and Magnesium minerals which helps
to improve the taste and quality of water. It also adds the required essential minerals
back to water and balances the pH of water.
