*Reverse Osmosis Purification System :It is a process wherein water is forced through a semi permeable membrane by applying strong pressure,thereby allowing only fine water molecules to pass through it all contaminants such as bacteria,virus,herbicides heavy metals and chemical poisions are removed.With added special features,pure water i... s then collected in a container,dirty water with impurities discharged separately.
*Granular Activated Carbon(GAC) : It is made from raw organic materials(such as coconut shells or coal) that are high in carbon.Heat,in the absence of oxygen,is used to increase(activate) the surface of area of the carbon;this is why these filters are sometimes referred to as ''charcoal'' filters.The activated carbon removes certain chemicals that are dissolved in water passing through a filte+ More
