Aluminum Sulphate for Drinking Water Treatment

There are various ways to add aluminum sulfate in drinking water treatment, with two common methods being static or dynamic addition. Static addition is the process of uniformly pouring a drinking water treatment grade aluminum sulfate solution into the water, and then stirring it thoroughly to make it evenly dispersed. Dynamic dosing is the continuous injection of drinking water grade aluminium sulphate solution into water through pumps and other equipment to ensure uniformity and stability of dosing.

The addition time of aluminium sulfate for drinking water is generally in the early stage of the water treatment process. After adding aluminum sulfate, the water should be thoroughly stirred to promote sufficient contact and mixing of drinking water grade aluminum sulfate with suspended solids, colloidal substances, and organic matter. Normally, the stirring time is 10-30 minutes, depending on the size and water quality of the water treatment system.

During the use of aluminium sulphate in drinking water, the following points should be noted. Firstly, aluminum sulfate is an acidic and corrosive substance. When using it, protective gloves and glasses should be worn to avoid direct contact with the skin and eyes. Secondly, the storage of drinking water grade aluminum sulfate should avoid mixing with other chemicals to avoid chemical reactions. Finally, after adding aluminum sulfate, the containers and equipment used should be cleaned in a timely manner to prevent residual aluminum sulfate.

To sum up, aluminum sulfate plays an important role in water purification as a drinking water treatment agent. The correct usage method can ensure that aluminum sulfate achieves the best treatment effect. The determination of dosage, dissolution process, dosage method, and stirring time all need to be considered to ensure the effectiveness and safety of water treatment. .
