Aluminum Sulfate Effects on Water
On the role of alum in water
Those who taste water are also the source of life, but whether it is pure or not is related to people's livelihood. To obtain the method of purifying water, the role of alum in water cannot be ignored.
For alum, it melts when it enters water, and the aluminum ions it contains change in contact with water. Aluminum ions hydrolyze to form an aluminum hydroxide colloid, which has unique properties. Its surface area is large, and its adsorption force is strong. Suspended particles in water, such as sediment, humus, etc., are all adsorbed by this colloid. The particles adhere to the colloid, gradually accumulate and grow, and finally settle to the bottom of the water, and the water is cleared. This is the wonder of alum to clarify water.
And alum in water can affect its acidity and alkalinity. In the process of hydrolysis, hydrogen ions are formed, causing the acidity of water to increase slightly. Although this change is subtle, it may also have a certain impact in specific environments, such as water bodies inhabited by certain organisms.
Furthermore, in the process of water disinfection and purification, alum is also indispensable. It makes impurities in the water settle, paving the way for subsequent disinfection steps. Disinfectants can better play their role, killing bacteria in the water, and ensuring water safety.
However, everything has advantages and disadvantages. Alum is used in the treatment of water. If the dosage is improper, there will be too many aluminum ions remaining in the water, or there may be potential threats to human health. Excessive intake of aluminum can affect the nervous system, bone development, etc.
To sum up, alum in water can not only clarify water quality and help disinfection, but also need to be used with caution to prevent aluminum ion residue. Only by weighing the pros and cons and using it rationally can the purification of water achieve the best effect and ensure the safety of people's water use.
