5. Phosphate Compounds These chemicals, particularly orthophosphate, are used to control corrosion in water distribution systems. Adding phosphates can reduce the leaching of lead and other metals from pipes, thereby enhancing the safety of drinking water.
One of the initial steps in water purification is coagulation, which involves the addition of chemicals called coagulants. The most commonly used coagulant is aluminum sulfate, often referred to as alum. When added to water, alum reacts with the impurities, causing them to clump together into larger particles (flocs). This process enhances sedimentation, allowing the flocs to settle at the bottom of the treatment tank more easily. Other coagulants, such as ferric sulfate and polyaluminum chloride, are also used based on the specific characteristics of the water being treated.
So where can individuals find Vitamin PQQ? While it is present in small amounts in some foods, such as green tea, kiwi, and fermented soy products like natto, supplementation may be a more effective way to achieve therapeutic levels of this vitamin. PQQ supplements are widely available, and many people take them to harness their potential health benefits.
