Reliable Safety “Supplying safe water to the world”
MIZUHA Co., Ltd. is working daily to " Supplying safe water to the world". We are pleased to announce that we have obtained new water quality test results.
Water made from air generally does not contain mineral components.
KuSui's drinking water has never been pure water. However, we have developed a new lineup to meet the demand for mineral addition. The new lineup includes a new original water filter for adding minerals, resulting in drinking water with even more mineral content than before.
The results obtained this time (mineral addition water quality test results, total hardness 65.4 mg/L) have been evaluated by experts as not bad.
[Total hardness]
The amount of calcium and magnesium ions in water is converted to the corresponding amount of calcium carbonate (CaCO3), expressed as mg mass contained in 1 liter of water, and the total amount of calcium and magnesium hardness is called total hardness.
Total hardness = calcium hardness + magnesium hardness
Hard water : water with a high total hardness (too hard and it may upset your stomach)
Soft water : water with low total hardness (too low and it will not taste good)
Standard for good tasting water : hardness 10-100 mg/L (around 50 mg/L is preferred by many people)
Water quality standards in Japan : Standard value 300 mg/L or less
Water quality control target set by the Water Supply Law in Japan : Target value of 10 mg/L or more and 100 mg/L or less
MIZUHA will continue to evolve with the mission of “Supplying safe water to the world”.
