Bottled water can be defined as any potable water intended for human consumption
Types of Bottled Water
Spring water: This comes from an underground formation and must flow naturally to the earth surface.
Mineral water: Typically from a spring, contains dissolved solid like Ca2+,Mg2+ ,Na+,K+,Si & CO3-3 .
Purified drinking water: Water has been processed to remove Cl-,Mg2+,Ca2+.
Sterile water: Water from any source, But free from all microbes
Water table well
Artesian well, well from which water flows under natural pressure without pumping. It is dug or drilled wherever a gently dipping, permeable rock layer receives water along its outcrop at a level higher than the level of the surface of the ground at the well site
Water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be conveniently visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity.
Spring is a component of the hydrosphere. Specifically, it is any natural situation where water flows to the surface of the earth from underground. Thus, a spring is a site where the aquifer surface meets the ground surface.
Surface water is water on the surface poof the planet such as in a stream, river, lake, wetland, or ocean. It can be contrasted with groundwater and atmospheric water.
Ozonation is a water treatment process that destroys bacteria and other microorganisms through an infusion of ozone, a gas produced by subjecting oxygen molecules to high electrical voltage.
Ultraviolet(UV) Radiation can be an effective viricide and bactericide. Disinfection using UV radiation is commonly used in wastewater treatment applications and is finding an increased usage in drinking water treatment. Many bottlers of spring water use UV disinfection equipment to sterilize their water. Solar water disinfection is the process of using PET bottles and sunlight to disinfect water. Ultraviolet germicidal irradiation is the generic process to inactivate microorganisms in water, air, medical environments etc.
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane. This membrane-technology is not properly a filtration method. In RO, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential, a thermodynamic parameter.
Micron Filtration, a Filter system used to clean dust particles as small as one micron in size.
