7 Stage RO Water Filter Technology
Reverse osmosis (RO) is a process of water filtration in which, a thin membrane filters water killing bacteria and blocking ions and other large molecules. This membrane, in combination with water filter cartridges, lowers the Total Dissolved Solutes (TDS) to an agreeable healthy level most recommended by World Health Organization (WHO). RO is suitable for all types of water filtration necessities. Whether you need a unit for your house or your industrial usage (e.g., food and beverages, boilers and mineral water supply for commercial use etc.), RO is the ultimate solution to all your water purification problems.

7 Stage RO Water Filter Process:
7 stage reverse osmosis ( R.O.) water filter with large 4 gallons water storage tank and water faucet. This RO system comes with premium quality, advanced thin film R.O. membrane to ensure highest-quality water production. Our 7 stage RO system offers up to 80 gallons high-quality drinking water per day.
All seven stages of water purification are explained below.

Stage 1:
Polypropylene filter ( PPF ) removes sediments such as, dirt, sand, silt, rust etc.

Stage 2:
Granular Activated Carbon filter ( GAC ) removes odor, chlorine and other alien components from water.

Stage 3:
Chlorine, Taste and Odor are further processed with the help of CTO carbon block filter cartridge.

Stage 4:
Water goes through special RO thin film membrane. Reverse osmosis (RO) is a special type of filtration that uses a semi-permeable, thin membrane with pores small enough to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria. Provides up to 99% reduction rate of bacteria & chemicals.

Stage 5:
Post carbon filter acts as the Polishing filter; it stabilizes the water tasting qualities and further removes any traces of bad tastes and odors.

Stage 6:
The Alkaline filter changes the acidic RO water into a perfect Natural Alkali Calcium Ionized Water. The Alkaline filter simply gives back minerals such as ionized calcium, magnesium, sodium, potassium ion, which were taken away while purifying the water.

Stage 7:
At sixth stage, minerals are added to already purified water. The filter improves the qualities of clean water by adding necessary Minerals for proper human development, such as Calcium, Magnesium, Sodium, Potassium and others readily found in many natural mineral waters.
