The term "very low sodium water" may seem like an oxymoron. After all, water is naturally composed of hydrogen and oxygen, not sodium. However, in the context of environmental and water treatment, this phrase refers to a specific category of bottled water designed for individuals with restricted sodium diets, particularly those suffering from medical conditions like high blood pressure or heart disease.
Defining Very Low Sodium Water:
Bottled water labeled as "very low sodium" typically contains 35 mg or less of sodium per serving, which is significantly lower than the sodium content found in many other bottled waters and even tap water. This low sodium content makes it an essential option for individuals needing to restrict their sodium intake.
Importance in Water Treatment:
While naturally occurring water sources may contain varying levels of dissolved minerals, including sodium, the presence of high sodium levels can be detrimental. Here's where water treatment processes come into play:
Benefits of Very Low Sodium Water:
The Future of Very Low Sodium Water:
As awareness of sodium's impact on health grows, the demand for very low sodium water is expected to increase. This trend will drive innovation in water treatment technologies and encourage the development of more sustainable methods for producing very low sodium water.
Conclusion:
Very low sodium water is a valuable resource for individuals seeking to manage their sodium intake. The water treatment industry plays a vital role in providing access to this crucial water source, contributing to the health and well-being of those who need it most. As our understanding of sodium's impact on health continues to evolve, the role of very low sodium water in promoting a healthier lifestyle is likely to become even more prominent.

Scenario: You are a water treatment plant operator tasked with providing water that meets the requirements for "very low sodium" water. Your current source water has 50 mg/L of sodium. You have access to a reverse osmosis (RO) system that can remove 90% of dissolved sodium.
Task: Calculate the remaining sodium content in the treated water after passing through the RO system. Is this water suitable for "very low sodium" labeling?
Sodium removal by RO: 50 mg/L * 90% = 45 mg/L Remaining sodium: 50 mg/L - 45 mg/L = 5 mg/L
The treated water would have 5 mg/L of sodium. Since this is less than the 35 mg/L threshold for "very low sodium" water, it would be suitable for labeling.
