Introduction

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
microorganisms like bacteria, virus, protozoa and cysts.
Stage 5 –
Silver Activated Post Carbon
Water is passed through Silver Activated Post Carbon which acts as polisher and
enhances the taste of water.
A. O. Smith Under Sink RO water purifier uses one of the latest technologies that
is used in water purification process. A. O. Smith Under Sink 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.
• Microorganisms such as pathogenic bacteria, virus, protozoa and cysts.
A. O. Smith Under Sink RO water purifier removes excessive TDS (Total Dissolved
Solids) in water by more than 95%. A. O. Smith Under Sink RO water purifier reduces
heavy metals and removes pathogens. By this, it ensures you safe and great tasting water.
A.O. Smith Under Sink RO water purifier has 5 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.
 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.
