Production of Sulphuric Acid has come to be accepted throughout the world as a reliable barometer of industrial activity. It is used in the process industries from very dilute concentrations for Ph control of saline solutions to strong fuming acids used in the dye, bleaching, explosives, and pharmaceutical industries.

Sulphuric acid is not a one-grade product. It is produced and supplied in grades of exacting purity for the storage battery, rayon, dye, tannery, water purification and in grades of less exacting specifications for use in the steel, heavy chemical and super phosphate & zinc sulphate industries. Sulphuric acid is used to produce ferrous sulphate, alum etc which are consumable in ETP plants. Lead acid batteries are used to run automobiles, ships, aroplanes, UPS, IPS in addition to store DC Current where a large amount of sulphuric acid is consumed. Additionally, the world is in crisis of power generation. Solar source is pointed out to cover the crisis. In remote area, solar source is now come to popular. A large amount of Lead Acid Batteries made of sulphuric acid are used in preserving such solar energy. Indeed it is so practical to say that the future of world will be on solar power. Bangladesh is also towards this for its rural/remote areas.
