[Technical Information] Aluminium sulphate – 200 Mesh Polysol Industries Plot no.-C1B-106/1 to 106/4, G.I.D.C, Sarigam(Gujarat)-INDIA Tel-091-0260-2431587, E-mail: [email protected] Aluminium sulfate is mainly use as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. It is widely use in the concrete technology as accelerating agent. Nature: Aluminium sulfate, is a chemical compound with the formula Al2(SO4)3 14-18H2O CAS Number 7784-31-8 Specification: Form : Powder Appearance : White fine free flowing Powder pH value (1:10) : Min. 2.0 Solubility : Completely soluble in hot water. Al as Al2O3 : Min. 15 % Insoluble matter : Max. 0.8 % (In water) Iron content as Fe : Below 50 ppm Particle size (Retention on) 100 Mesh sieve : Max 2.0 % 200 Mesh sieve : Max 35.0 % 300 Mesh sieve : Max 95.0 % Properties: Aluminium sulfate, alternatively spelt either aluminum or sulphate, is a chemical compound with the formula Al2(SO4)3. Aluminium sulfate is sometimes referred to as a type of alum. Application: Sizing paper, lakes, mordent for drying, foaming agent in fire foams for leather and clarifying agent for fat and oil. Aluminium sulfate is used in water purification 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 container or more easily filtered. This process is called coagulation or flocculation.When dissolved in a large amount of neutral or slightly alkaline water, aluminium sulfate produces a gelatinous precipitate of aluminium hydroxide, Al(OH)3. In dyeing and printing cloth, the gelatinous precipitate helps the dye adhere to the clothing fibers by rendering the pigment insoluble.
