The use of aluminum sulfate in various industries has made this material one of the most important basic materials in papermaking, polymer and water treatment industries. Aluminum sulfate, which is one of the two aluminum alums. Due to the characteristics and reactions it creates, it can be a good option for use in the mentioned industries. In this short article, we will talk about the use of this chemical in water purification.
What is aluminum sulfate?
Aluminum sulfate, which is also known as white alum or alum, is one of the chemical substances obtained from the chemical reaction of sulfuric acid with liquid aluminum hydroxide, and it is usually produced in the form of crystal powder or white liquid.
The production of this material is a process that must be carried out under controlled pressure and temperature and under standard conditions. that have Iran’s national standard certificate to prepare this product . to companies and brands such as Golgah Company For this reason, it is recommended to only refer
This substance is able to absorb suspended particles in water, in which case its acid strength increases and its pH reaches less than 2. The melting temperature of this material is 770 degrees Celsius and it has a density of 2.6 grams per cubic centimeter.
Due to the trivalent nature of its molecules, this powerful ion is able to absorb a large amount of microorganisms in the water, and like a molecular chain that gradually gets heavier and deposits at the end of the chamber. in detail . about the use of aluminum sulfate In the following , we will talk
Application of aluminum sulfate in water purification
More than 50% of aluminum sulfate produced in the world is used in paper and cardboard industries; But after that, the second most important application of this material is in the water purification process. As mentioned, this material with its trivalent molecules is capable of absorbing suspended particles and microorganisms floating in water. For this purpose, this product is used to remove water turbidity.
The best option for this application of aluminum sulfate is that this material is produced with a concentration of 17% and in the form of fine powder. In this case, the surface that can be contacted with water is at its maximum state and dissolution occurs faster. Therefore, the production of this product itself has standards that must be followed.
How to use aluminum sulfate
Another point about this application is the method of using aluminum sulfate. The amount of dosage and the method of adding it to the purification process can be different in different conditions. For example, this material is used to clarify the water of pools and artificial lakes, and this happens before the water passes through the filter. Because when the colloidal particles in the water stick to each other by this substance, they form the heaviest particles that will no longer pass through the filtration filters. In many swimming pools, about 99% of water impurities are removed with this simple method.
Undoubtedly, the use of the same substance in the treatment of wastewater or industrial waste from factories and waste leachates are different in terms of the method of consumption and usable dose. It is better to read and research carefully in this field before you want to start working.
