EXAMPLE: Waterworks of a town treat 35 x 106 litres/day. The water is treated by coagulation-sedimentation tanks. The quantity of filter alum is consumed at 20 mg/litres of water. If the alkalinity of the raw water is equivalent to 4.5 mg/litre of CaCO3, determine the quantity of filter alum and the quick lime (containing 80% of CaO) required per month by the water works. Molecular weights are given as [Ca = 40, C = 12, S = 32, O = 16, Al = 27 and H=1]

Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.
