Alum is a form of specific chemical compound that has been used for drinking water filtration for long years. Often known as Aluminium Sulfate or Aluminum salt, Alum is white, gelatinous sticky material in nature, which easily traps particles in the water; in combination with lime, soda ash or caustic soda, it ensures that the optimum coagulation (dosed-water) pH is achieved; in addition, it removes unwanted colour and turbidity from the water. After preforming its role of purifying water, it is removed from the tank.
Considered a low cost coagulant, alum is widely available on the Indian market today. Bionics Consortium Pvt. Ltd. is a one of leading alum manufactures in India and supplies it at highly competitive wholesale price all over India and overseas.
