Description 89-93
Water has become a limited resource in the modem scenario. The scarcity of potable water is not limited to India but
it is an increasing problem throughout the globe. Adequate and appropriate management of water is essential. It is
said that if there would be·the 3rd World War then it would be for water and not anything else. In view of acute
shortage of potable water there is vital need to conserve water and use it appropriately. Polyelectrolytes are boon
for treatment of domestic and industrial effluents. Polyelectrolytes are generally synthetic chemicals and may be
ionic or non-ionic. Polyelectrolyte has a wide range of molecular weight and charge density. Beside use in water
treatment, polyelectrolyte is also used in oil recovery, color removal, paper industry, mining etc. There are many
institutes engaged in the manufacture of polyelectrolyte. Sometime the chemical present in polyelectrolyte may
adversely affect public health, thus it is important to assess its toxicity and suitability at intended usage dose prior
to its application in water treatment. Many regulatory agencies are engaged in safety evaluation, framing or updating
of guidelines periodically and specified use of polyelectrolyte as per IS 15573:2005 and OECD etc. The facility for
safety evaluation exists at Indian Institute of Toxicology Research, Sriram Institute for Industrial Research and
several other organizations of repute.
