Abstract: | Boiling of water, for purification, commonly practiced in the world, has many problems associated with it like danger of scalding, scaling in the vessels, removal of useful minerals and blandness of taste etc. Water can be made safe for drinking simply by heating at 65 degrees C for 6 minutes. A colour indicating strip was developed which changes colour from red to purple at 67 degrees C. Use of this strip can help in pasteurizing water without the above problems and with considerable energy saving. |
