Introduction
A. O. Smith / Water Puri er uses one of the latest technologies that is used
in water puri cation process. A. O. Smith / Water Puri er works under the
principle of RO (Reverse Osmosis) technology which is found to be one of the
most e ective process. In this process water under pressure is passed through a
semipermeable membrane. Puri ed water is collected for drinking in a storage
tank and impurities in the water are ushed to the drain
Why Water Puri cation is important?
Water puri cation, today is essential due to the presence of harmful
contaminants present in the water supply. Rapid urbanisation and speedy
industrial growth have led to signi cant 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 Puri er removes excessive TDS (Total Dissolved Solids)
in water by more than 95%. A. O. Smith / Water Puri er 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 / Water Puri er work?
A. O. Smith / RO Water Puri er has 6 stages of puri cation system, wherein
the water is passed through the various stages and progressively ltered to get
puri ed water which is stored in the inbuilt storage tank.
• Stage 1 – Sediment lter
The Sediment lter 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.
• Stage 2 and Stage 3 – SCB filter (Sediment and Carbon Block)
This is a dual filter (Sediment and Carbon Block) where Sediment filter
removes ne 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.
• 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.
