Our Process

Method of our Process

Our spring water is pumped from the storage tanks through an absolute one micron filtering system. The water then passes through a high-intensity, ultra-violet light disinfection system, a series of sanitary piping to yet another series of micron filtration devices before entering the ozonation Process. Generated ozone is pumped into the water through a stone of fine porosity, creating very small bubbles which rise slowly through the water. The slower the bubbles rise through the water, the greater the amount of ozone transferred to the water. Most critical for water quality, ozonation does not add chemicals to the water as does chlorine, chlorine dioxide, permanganate, etc. As the ozone passes through the water, the third unstable atom detaches, attacks and destroys impurities in the water. The residue in the water is pure oxygen, which quickly dissipates in a few minutes. Any excess dissolved ozone which is not needed for treatment reverts to simple oxygen in approximately 20-30 minutes.

The primary effects of ozonation of drinking water are:

-bacterial disinfection and viral inactivation;

-oxidation of inorganic elements such as iron, manganese, organically bound heavy metals, cyanides, sulfides and nitrates; and, oxidation of organics such as detergents, pesticides, herbicides, phenols and other impurities.

Keystone Water Company is committed to protecting and preserving the environment through the education and implementation of activities to promote waste reduction and recycling. We believe it is our responsibility to provide the greatest drinking water to our customers while promoting a sustainable future.
