Stage 3
– Pre Carbon filter
The Pre Carbon filter uses carbon block with high adsorbtion capacity which reduces
harmful chemicals including pesticides, volatile organic compounds, residual chlorine
etc., from water. It also adsorbs bad taste and odour causing organic compounds
from water.
Stage 4
– 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
disease causing microorganisms like bacteria, virus, protozoa and cysts.
Stage 5
– MIN-TECH (Mineraliser Technology)
The MIN-TECH contains Calcium and Magnesium minerals which helps to improve
the taste and quality of water. It adds the required essential minerals back to water
and balances the pH of water.
Stage 6
– Silver Activated Post Carbon
Water is passed through Silver Activated Post Carbon which acts as polisher and
enhances the taste of water.
Stage 7
– SCMT (Silver Charged Membrane Technology) filter In the final stage
water is passed through SCMT filter which ensures double purification of water
making it Pure & Sure for drinking.
A. O. Smith water purifier uses one of the latest technologies that is used in water
purification process. A. O. Smith 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.
Introduction
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 water purifier removes excessive TDS (Total Dissolved Solids) in water by
more than 95%. A. O. Smith water purifier reduces heavy metals, removes pathogens
and balances the pH value. By this, it ensures you safe and great tasting water.
A. O. Smith 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 Sediment filter.
Stage 2
– Sediment filter
The Sediment filter is used to remove fine and coarse physical contaminants present
in the water. This improves life of the Pre Carbon filter and ensures efficient working
of RO membrane.
