How to deal with low pH and hardness levels in drinking water that fall below the standards

2009-02-19View Original

Thread Content

In my branch office, the pH level of the drinking water has been around 6.5 in recent years, with a hardness of 15 mg/L. Such low levels of pH and hardness pose a certain threat to human health.   Based on the experience outlined in the book, the pH level should generally be maintained between 6.5 and 8.5 (according to national standards). Medical research shows that a value of around 7.45 is optimal, as it is slightly alkaline and similar to the pH level of human blood, making it the most easily absorbable.   The hardness generally ranges from 30 to 450 mg/L, with a level below 450 mg/L being the **standard**, while a level above 30 mg/L representing the optimal indicator for healthy drinking water.   I am starting this thread to seek advice from experts, scholars, and experienced individuals. Please let me know how to carry out the necessary processing, that is, how to increase the pH value and water hardness.   Thank you.

        The establishment of pH value standards takes into account the influence of pipelines, which serves as the basis for these standards. In fact, the pH value does not have a significant direct impact on human health. The current EU standard is 6.5–9.5; any value within this range is considered acceptable, with no effect on human health. If the pH level is too low or too high, it can have an impact on the pipes; a too-low pH can cause corrosion of the pipes, while a too-high pH can lead to scaling.         Based on existing information, hard water does not have any adverse effects on human health within certain limits. It’s just that the water is hard, giving it an unpleasant taste and making it uncomfortable to drink. The treatment of this indicator varies depending on the situation; currently, it is also mandatory to implement it in our country. Like other countries, such as the United States, they treat such indicators as non-mandatory. Currently, the hardness standard we have set is 450 milligrams per liter; this concentration is acceptable for ordinary consumers and has no impact on health. The World Health Organization sets a limit for this indicator at 500 milligrams per liter for hard water.         If the water is too soft, it will corrode the pipes. After the pipes corrode, the corrosive substances end up in the water that people drink, thus having an indirect impact on health. In terms of water supply, it is necessary to control so that the water is not too soft. The above information is from the Internet.

The pH value of drinking water is generally inversely proportional to its hardness; in other words, the lower the pH, the higher the hardness; The higher the pH, the lower the hardness. Your company’s pH and hardness levels are low, which may be related to the source of the water.

A pH level that is too low in drinking water is incompatible with the microenvironment of the human body; obviously, a too-high pH level is even worse. Therefore, countries adopt a range of values rather than a single critical value, which means that pH has not particularly significant effects on the human body. Total hardness has a significant impact on the human body; high levels can lead to the formation of stones in the body, and hard water makes people crave fatty foods such as fatty meat, which can also cause discomfort. Low levels are equally problematic, as they can result in bone softening. If both the pH value and total hardness are slightly low, the water can be appropriately concentrated. Generally, concentrating water leads to an increase in total hardness; at the same time, the alkalinity also rises, which in turn raises the pH value. Isn’t industrial circulating water just like that?

Your question is similar to the debate between purified water and mineral water – a debate that has raged on for years with no resolution yet. As for the issue of nutrition: The proponents of purified water argue that it contains no minerals and is therefore nutritionless. Purified water, which has gone through multiple treatment processes, contains very few minerals; while toxic elements are significantly reduced, calcium, magnesium, and other beneficial trace elements are also greatly diminished. Children in growth stages, pregnant women, athletes, obese individuals, people with cardiovascular diseases, and those with weakened immune systems should not consume pure water for extended periods or as their only source of water. Opposition: Mineral nutrients are not obtained from drinking water. Drinking water is not meant to provide nutrients; the minerals that the human body absorbs mainly come from animals and plants. The minerals found in surface water, well water, and mountain spring water are inorganic minerals, which the human body cannot absorb directly. Eating more beef, more vegetables, and drinking more milk provides levels of calcium and iron that are several hundred to several thousand times higher than those found in mineral water. Pro: Healthy water is slightly alkaline water. The pH level of the body’s internal environment should be between 7.35 and 7.45; in other words, our body fluids need to be slightly alkaline in order to maintain normal physiological functions. The pH value of pure water is generally between 5.0 and 7.0, indicating a slightly acidic nature. And the pH value of most mineral waters is higher than that of purified water, which is more acidic. Experts therefore recommend that consumers choose slightly alkaline water, which helps maintain the acid-base balance of body fluids. Opposition: There is no inherent connection between water pH and human health. There is no scientific evidence showing that there is a necessary link between water pH and human health. The pH level of stomach acid is around 3, and the human body has a robust acid-base balance mechanism; water with a pH level between 5 and 9 has no effect on the human body. As for the pH value in drinking water standards, it was determined during design taking into account that either too high or too low acidity can affect the lifespan of water pipes, without considering health factors. Debate on diseases: Pro side: Excessive consumption of mineral water leads to kidney stones. Patients with severe coronary heart disease, a tendency to have cerebral hemorrhages, or heart failure may see their condition worsen or even die if they drink too much carbonated mineral water. Patients with kidney stones that are over 1 centimeter in size and that have caused mechanical obstruction in the urinary system or led to hydronephrosis should avoid drinking large amounts of mineral water, as this can make the stones larger and increase the amount of fluid accumulation. Anti-mineral water does not cause kidney stones; long-term insufficient calcium intake does. Opposing side: It can instead lead to hyperthyroidism, cause a decrease in bone calcium, and an increase in blood calcium levels as well as calcium content in soft tissues. High blood calcium can lead to arteriosclerosis, high blood pressure, as well as stones, osteoporosis, and bone hyperplasia. The calcium needed by the human body mainly comes from food in the diet, with a relatively small amount obtained from water or mineral water. Drinking mineral water cannot cause kidney stones.

The world is truly amazing – there’s such good water, yet people are still looking for ways to manage it. Go and test the water in luxury hotels; it’s all of this quality. Even lower in hardness. Washing clothes in this way saves detergent; over time they don’t turn yellow, and the skin stays smooth after bathing without any itching. All benefits. Hehe. Rejoice in secret. In response to the **** call, please stop causing trouble. I’m so jealous.
