Wastewater Treatment Chemicals Industrial Grade Brown Granules Polyaluminum Chloride PAC​ ​

Polyaluminum chloride is a new water purification material, inorganic polymer coagulant, referred to as polyaluminum, abbreviated as PAC (poly aluminum chloride), which is a kind of between AlCI3 and Al(OH)3. Water-soluble inorganic high molecular polymer.
The raw materials of tan polyaluminum chloride are calcium aluminate powder, hydrochloric acid, bauxite and iron powder. The production process adopts the drum drying method, which is generally mainly used for sewage treatment. Because iron powder is added, the color is tan. The more iron powder is added, the darker the color. Known as polyaluminum ferric chloride, it has excellent results in sewage treatment.

Polyaluminum Chloride for Sewage Treatment
Sewage contains colloidal particles (the colloidal particles formed by water, such as dust, humus, cellulose, etc. in water), which cannot be removed by natural precipitation. Some chemicals (flocculants) must be added to decoagulate, aggregate, and flocculate the colloidal particles that are difficult to precipitate in water to precipitate into larger particles.
In order to determine the process parameters of the water flocculation process, such as the type and dosage of flocculants, the pH value of water, the temperature and the dosing sequence of various chemicals, simulation experiments are generally performed. Under the conditions of a certain water temperature and control of appropriate stirring intensity and time, use different flocculants and dosages to adjust the pH value of different color water experiments to see the flocculation effect.
