Potassium Aluminum Sulfate Water Purification
On the method of alum water purification
The purification of water is related to people's livelihood. Although there are no complicated equipment in ancient times, there are also wonderful methods of water purification, and alum water purification is one of them.
Alum, the chemical name is aluminum potassium sulfate, which has a significant effect on the way of water purification. It dissolves water and melts in contact with water. When cast alum in muddy water, its ions disperse quickly. Aluminum ions hydrolyze, and aluminum hydroxide colloid gradually emerges. This colloid is very magical, with a huge specific surface area, and can absorb all kinds of impurities in water, such as mud dust, leaf rot, and bacteria and viruses. Impurities adhere to the colloid, then condense into large particles and slowly settle. The upper layer of water gradually clarifies.
In the past, the people mostly took water from rivers, lakes and wells, and the water was often turbid. Some wise people threw alum into it, and with a little bit of water, the water became clear, ready to drink and cook. In daily water, such as washing rice, washing vegetables, and laundry, water purified by alum is more beneficial to the situation. And in the tank and urn of water storage, put an appropriate amount of alum, which can keep the water for a long time and less deterioration.
Looking at the ancient methods of purifying water, or filtering it with sand or stones, or waiting for natural precipitation, but the filtration of sand and stones is time-consuming and difficult to remove tiny impurities, and it is difficult to remove subtle things from natural precipitation. Alum purifying water alone is simple and easy to implement, and the effect is obvious. With a small amount of alum, it can make turbid water clear, which is the crystallization of the wisdom of the ancients and adds a treasure to the method of purifying water.
