The water supplied for refills and bottling is purified through reverse osmosis purification, ozonation and deionization processes and offers the cleanest, healthiest solution to drinking water.
Darling's 11 Step Purification Process:
STEP 1: AG Pre-Filtration – cartridge type, removes particulate matter down to 20 microns.
STEP 2: Carbon – an activated carbon cartridge filter that removes chlorine, chloramine, solvents, lead, insecticides, gasses, and other harmful contaminants. Works as a water softener, without the use of salt and drawing hardness particles together and crystallizing them. Includes an automatic backwashing system.
STEP 3: 5 Micron Pre-Filter – removes particles, sediments, and algae.
STEP 4: R.O. Pump – high pressure, stainless steel pump to boot water pressure to 160 lbs. for maximum membrane efficiency.
STEP 5: Reverse Osmosis Membrane – water is forced through a semi permeable, .0002 micron membrane, allowing only pure water molecules to pass.
STEP 6: Storage – water is stored in FDA approved tanks.
STEP 7: Repressure System – 12 GPM pressure pump assures constant water supply from storage tanks to post carbon filter, ultraviolet sterilizer, and faucets.
STEP 8: Pressure Tank – 32 gallon pressure tank assures a constant flow of water to the filler and prolongs pump life.
STEP 9: Post Carbon Filtration – water travels through a 4.5in x 20in coconut shell carbon block filter, polishing it for an exceptionally smooth taste.
STEP 10: Ultraviolet Sterilizer – stainless steel sterilizer eliminates up to 99.9% of all bacteria.
STEP 11: Ozone – Ozone may be added to water storage tanks to prevent future bacterial growth.
