eGuide to Culligan Bottled Water Purification Process


We all need to drink lots of water every day. But water that looks bad (cloudy water, or water that has a yellow, white or rusty tinge to it), does not look very inviting. It’s even worse when your water has a bad odor or poor taste. If you have problem water – that’s a big deal! Fortunately, Culligan Bottled Water’s purification process can solve 100% of your drinking-water problems. Water Filtration and Purification Process: Water is a solvent, meaning it has the ability to dissolve other substances – which is great in certain circumstances, like when you need to add detergent to a load of laundry to wash your clothes. But this trait can lead to problems in your drinking water when you consider the long journey your water takes before ever reaching your home’s faucet. Before making it to your tap, your water is collected from a natural source where it’s been flowing through the earth, and is diverted into

a water treatment center where it is processed before being distributed to your home. Along its journey, your water can absorb dirt, chemicals, and other contaminants that lead to a disagreeable appearance, poor taste, and unpleasant odor. The process of water filtration and purification takes problem water and turns it into cleaner water that’s free of those offensive appearances and tastes, as well as sediments and other contaminants. Water purification and filtration works in one of two ways – physical filtration and chemical filtration. With physical filtration, water is strained, often through a gauze-like membrane, to remove larger particles. With chemical filtration, water is treated with patented smart technology to remove impurities.

So how does Culligan Bottled Water do it? Culligan delivers bottled water that’s free of unwanted minerals, chemicals and organic compounds, by using a process called reverse osmosis filtration. Reverse osmosis is a multistep solution - it uses five stages of purification to clean the water. Culligan Bottled Water Explained As water enters Culligan’s water purification facility, it immediately passes through two parallel carbon filters that remove chlorine and total dissolved solids. The water is then softened to remove hardwater-causing minerals, like calcium and magnesium, to prevent scaling inside the cooler. The softener will also remove aluminum, copper, and other trace metals, while a secondary polishing softener keeps the water equipment free of residue.

At this point, the water is ready for primary filtration – this is where reverse osmosis comes in. The RO filtration removes any remaining contaminants down to the size of a micron. In case you’re wondering how big a micron is - it’s really tiny. For example, a micron is 1/60th the size of a grain of salt. In the final step of Culligan’s water filtration process, the water passes through ozone and ultraviolet filtration to ensure the water is free of microorganisms. Culligan’s Water Bottles are Recycled and Reused Culligan water bottles are reusable – in fact, the average Culligan water bottle is reused 60 times. When your Culligan Man picks up your empty water bottles, he brings them back to the water bottling plant to be disinfected and reused.

Culligan Water Quality Standards

Ozone Filtration vs. Chlorine in Water

Culligan goes above and beyond to make safe drinking water that is a healthy choice for our customers.

Culligan uses ozone filtration, instead of putting chlorine in water, in the final step of bottled water production. Ozone (chemical formula O3) is a compound of oxygen that is bubbled through the water just before it goes into a clean and sanitized water bottle. Within a few hours of being filled and capped, the ozone dissipates and converts back to the same oxygen found in the air, O2.

Water Quality Standards • •

The Food and Drug Administration (FDA) establishes water quality standards for bottled water. The Environmental Protection Agency (EPA) regulates tap water provided by water utilities (EPA standards) to ensure safe drinking water. The FDA Standards of Quality (SOQs) for bottled water must be as protective of public health as EPA standards - known as Maximum Contaminant Levels - for safe drinking water. Culligan’s bottled water meets or exceeds all federal and state health water regulations.

Ozone Filtration Ozone filtration, also known as ozonation, is the process of putting ozone in water to destroy bacteria. Unlike chlorine, ozonation leaves no residual chemicals and does not cause a bad water taste or an unpleasant water smell. Cleaner Water, Pure and Simple It is a basic human right to be able to drink clean healthy water. Culligan has more than 80 years of experience purifying and filtering water. While Culligan’s water purification process may sound complex, the result is better water. Pure and simple.
