Introduction

Puritee RO water purifier uses one of the latest technology system that is used in water purification process. Puritee RO water purifier works under the principle of RO (Reverse

Osmosis) technology which is found to be one of the most effective process in the world. 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 vivid and 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. This 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)

• VOC (Volatile Organic Compounds)

• Heavy metals like Iron, Mercury, Arsenic, Copper, Lead etc., Pesticides,

Imbalanced pH.

• Micro organisms such as pathogenic bacteria, virus, protozoa and cysts

Puritee RO water purifier removes excessive TDS (Total Dissolved Solids) like Calcium,

Magnesium, Sodium, Bicarbonates, Chlorides and Sulphates in water by 90%. This restores the natural taste of water and removes bacteria and viruses. Puritee RO water purifier also reduces heavy metals like Arsenic, Fluoride and Lead. It balances the pH value and it also removes bacteria and viruses. By this, it ensures you safe and great tasting water.

How does Puritee RO water purifier work?

Puritee RO water purifier has 5 stages of purification system, wherein the water is passed through the various stages & progressively filtered to get purified water which is stored in the inbuilt storage tank.



Stage 1 – Pre-PP (Poly propylene) filter

The Pre-PP filter is used to remove physical contaminants such as dirt, dust, soil particles, turbidity present in the water. This improves the life of the Advanced PP filter.



Stage 2 – Advanced PP (Poly propylene) filter

The Advanced PP filter is used to remove fine and coarse physical contaminants present in the water. This improves life of the CB filter and ensures efficient working of RO membrane.

Stage 3 – Pre-CB (Carbon Block) filter

The CB filter uses carbon block with high adsorption 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, Copper, Lead etc. It also removes micro organisms like bacteria, virus, protozoa and cysts.



Stage 5 – PAC (Post Activated Carbon) filter

After the RO membrane water is passed through post activated carbon which acts as polisher and enhances the taste of water.



Stage 3 – Pre-CB (Carbon Block) filter

The CB filter uses carbon block with high adsorption 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, Copper, Lead etc. It also removes micro organisms like bacteria, virus, protozoa and cysts.

Stage 5 – PAC (Post Activated Carbon) filter

After the RO membrane water is passed through post activated carbon which acts as polisher and enhances the taste of water.
