Does Boiling Tap Water Remove all the Contaminants

Bacteria and parasites are all eliminated at boiling temperatures – which are the contaminants found in water that can impose the greatest threat to human health in a short amount of time. Does Boiling Tap Water Make it Pure? While boiling water ensures that no bacteria is present in the water, it does not make the tap water pure.

Pre-treating the feed water is essential to best controlling for corrosion and scale. Heating, adding oxygen scavengers, reducing alkalinity, and softening the make-up/feed water will drastically reduce corrosion and scale build up. We also offer make-up water pre-treatment equipment including filtration, softening, dealkalzing and reverse osmosis.
