Contribution of Chemistry to Portable Water Industry

CONTRIBUTION OF CHEMISTRY TO PORTABLE WATER INDUSTRY
POSITIVE CONTRIBUTIONS
Of all the inputs of industry, the most critical is the RAW-MATERIAL because it plays a significant role in the nature, quality and quantity of the other four factors namely: technology, capital, labour and management. It is on this most crucial factor that chemistry plays its role.   The truth of this assertion is clearly evident by merely taking a careful look at Chart 1.

The role of chemistry if the conversion of matter from one form into another.   Since this also is the aim of industry, chemistry has come to be regarded as the KING of Industry because of its utilitarian value to industry in which it platys a “primus inter pares” role and in some cases its role is “sine qua non” for industries.   A few examples will drive home these assertions.

      Portable Water Industry: Food, which is the most basic of all the needs of man, can be subdivided into air, water and food (per se).   Although air and water are divine provision, the impact of life (plats, animals and human) has produced some adverse effects on the quality of these needs, especially water.   The quality of water can be examined within four sub-sections; physical, chemical, bacteriological and biological.   The main physical characteristics for which water is examined are: appearance, colour turbidity, odour and taste (and at times temperature).   In fact these are the only important characteristics to a villager.
      The neglect of the other parameters led to (and still accounts for) the deaths of thousands of human beings. Today, science has led us into the appreciation of these other factors.   Thus, chemistry has revealed the deleterious effects of toxic chemicals in water and how to remove them.
      A few examples are:
      (i) Nitrates (If present in concentrations greater than 45mg/L) present a health hazard to infants, because, after reduction to nitrites, they may give rise to methaemoglobinaemia.   Also...
