Addition of Magnesium to Desalinated water

Do you think that desalinated seawater should be supplemented with magnesium? As WHO and other drinking water regulators are considering introduction of compulsory requirement for addition of magnesium to desalinated water because some studies shows that low level of magnesium in human diet may have negative impact on health.

   1. Thank you Tanvi: Hopefully you would find the book useful - it provides additional engineering information on the issue of magensium addition to desalinated water. Kind Regards, Nikolay

2. I am in support of supplementing desalinated water with magnesium an I do believe magnesium addition will be beneficial for human health. Magnesium in desalinated water is usually quite low - typically less than 2 mg/L. WHO is considering recommendation to add at least 5 to 10 mg/L of magnesium to desalinated water as a supplement enhancing cardiovascular health. Besides human health, another important factor in favor of magnesium supplementation is that this is a critical compound for many agricultural crops and ornamental plants. The level of magnesium needed for desalinated water application for agricultural purposes is relatively high - 15 to 20 mg/L. In any case, addition of magnesium is not expected to increase water production by more than 5 US cents per cubic meter and is certainly worthwhile. Nikolay Voutchkov, Water Globe Consulting
