Herbert F.: My employees have been using the new water ionizer in our tax office for a few weeks. I also offer our clients a carafe of water as an alternative to coffee, tea and fruit juice during consultations. The glass carafes now have a milky coating that is particularly deposited on the floor. An employee has already asked me what deposits it is. Between the lines I heard the question of whether the water was really as healthy as I had advertised. For some skeptics in the company, this is grist for their mill to question the well-intentioned action. I would like to answer relevant questions competently. How should the glass carafes be cleaned in order to convey the purity of the water, or are there more suitable containers to present the water in an attractive way?
It is clear that you cannot give each of your clients a seminar about the fundamental importance of calcium in our lives. Therefore, your question about the presentation of the water is completely correct, although unfortunately difficult to answer.
First for your own understanding: The whitish deposits are compounds of calcium with carbonic acid. Nothing harmful, but not particularly useful either. As soon as they occur, the alkaline active water has its effect —> Relaxation time exceeded and should be renewed.
The more air contact there is, for example when stored openly in water carafes, the shorter the relaxation time is because carbon dioxide from the air is drawn into the activated water as carbonic acid and flocculates as calcium carbonate.
It is therefore absolutely preferable to present the water in bottles filled to the brim and sealed airtight. Violet glass is considered the cheapest material, followed by blue glass and brown glass. These bottles extend the relaxation time best.
In addition, Tritan, a new plastic without plasticizers, is also an option, but deposits on it become very obvious if it is not cleaned properly.
Storage containers that have not been descaled promote the shortening of the —>Relaxation time, because they provide crystallization nuclei for the calcium carbonate. They dissipate the negative redox potential almost like a metal bottle – which is forbidden for alkaline active water.
Therefore, always descale all storage containers.
Acidic water from a continuous ionizer is usually not acidic enough to remove a built-up layer of limescale. It's best to use a squeeze bottle with biologically safe citric acid and swirl a squirt in the bottle until the milky deposits are removed.
Then rinse briefly with tap water and you can refill the container. Unfortunately, this is a bit annoying, but there is no other way. It is best to drink alkaline activated water immediately after bottling. Of course, this is not possible in your office.
