A. O. Smith Advantages

Introduction

O. Smith Z8/Z9 RO Water Purifier uses one of the latest technologies used in the water purification process. A. O. Smith Z8/Z9 RO Water Purifier works under the principle of RO (Reverse Osmosis) technology which is found to be one of the most effective processes. In this process water under pressure is passed through a semipermeable 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 urbanization 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.

• t TDS (Total Dissolved Solids) like Nitrates, Chlorides, Sulphates etc.
• Pesticides and VOC (Volatile Organic Compounds).
• Heavy metals like Mercury, Arsenic, Lead, Chromium, Cadmium, etc., have imbalanced pH.
• Microorganisms such as pathogenic bacteria, viruses, protozoa, and cysts.

A. O. Smith Z8/Z9 RO Water Purifier removes excessive TDS (Total Dissolved Solids) in water by more than 95%. A. O. Smith Z8/Z9 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 the A. O. Smith Z8/Z9 RO Water Purifier work?
A.O. Smith Z8/Z9 RO Water Purifier has 8 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 in-built storage tank.

• Stage 1 – Pre-filter
  The Pre-filter is used to remove physical contaminants such as dirt, dust, soil particles, and 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 the life of the ART™ MAX.
• Stage 3 – ART^TM MAX (Advance Recovery Technology™)
  The ART™ MAX (Advance Recovery Technology™) is a scale control media that conditions the water to reduce scaling potential in water.
• Stage 4 – SCB filter®
  The SCB filter® uses carbon block which reduces harmful chemicals including pesticides, volatile organic compounds, residual chlorine, etc. It also adsorbs bad taste and odor-causing organic compounds from water.
• Stage 5 – RO (Reverse Osmosis) membrane
  RO membrane contains a 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, viruses, protozoa, and cysts.
• Stage 6 – MIN-TECH (Mineraliser Technology)
  The MIN-TECH contains Calcium and Magnesium minerals which help to improve the taste and quality of water. It adds the required essential minerals back to water and balances the pH of water.
• Stage 7 and Stage 8 – ZX Double Protection Dual filter®^É
  This is a dual filter where water is passed through an activated carbon block which acts as a polisher and enhances the taste of water. In the final stage, water is passed through the SCMT (Silver Charged Membrane Technology) filter which ensures double water purification, making it Safe and Healthy for drinking.
