Distillation is a water purification process that uses a heat source to vaporize water and separate it from contaminants and other undesirable elements commonly found in ground and surface water. The prolonged boiling process kills virtually all types of microorganisms, including bacteria, viruses and parasites.
Distillation heats raw (untreated – for example tap water) water until the water reaches its boiling point and begins to vaporize. The heat is then kept at a constant temperature to maintain water vaporization while prohibiting other undesirable elements from vaporizing. Water has a lower boiling point than salt and other mineral sediments. This process also separates the water molecules from microscopic, disease-causing organisms.
Once all of the water has vaporized, the vapour is led into a condenser, where, upon cooling, the water reverts to the liquid form and runs into a receiving container. The remaining elements, whose boiling point was too high to permit vaporization, remain in the original container and constitute the sediment. Additionally, a system with activated carbon filtration and venting is effective in removing volatile organic compounds (VOCs).
Distillation provides consistent purity, litre after litre, year in and year out.
