Aluminium Sulphate Flakes


Aluminium sulfate (Aluminum sulphate) is a chemical compound with the formula Al2(SO4)3. It is soluble in water and is mainly used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing and as a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate which are removed as the particulate settles to the bottom of the clarifier or more easily filtered. This process is called coagulation or flocculation. A coagulant is therefore usually the first chemical that is added in water clarification processes. After adding a coagulant, pin sized flocc particles are formed. To help make the flocc grow larger in size so that it will separate more easily from the water, a second chemical is added and this is usually a polymer. The polymer helps to collect the pin sized particles together to create bigger floccs that either sink faster or are more easily floated in a DAF system. Aluminium sulphate is used in paper industries after the waste water management. It works for the treatment of various problems as it works as flocculant, emulsion breaker coagulant and precipitant. These are easily soluble and can be filtered easily.
