Aluminum sulfate for water and wastewater treatment

Aluminum sulfate for water and wastewater treatment

Aluminum sulfate, the first and most important application, is in process of purification of drinking water, industrial water and wastewater. Aluminum sulfate has a very high coagulation property, which has led to the use of about 99% of the excess material in such cases to create sediment and sediment. In fact, by adding aluminum sulfate to untreated water, the impurities in the water stick together. In this case, the so-called impurities are called clots. Over a short period of time, the accumulation of these impurities increases and they form larger particles. In this way, in the water treatment process, impurities are more easily detected. Because multiple filters are placed in the path of the water treatment process, these particles get stuck in the filters and separate from the water. It is important to note that the amount of aluminum sulfate used in water treatment should always be measured so that it does not exceed the standard. Otherwise, it is known as contamination and renders the result of aluminum sulfate ineffective.
