New techniques in water treatment.
By Dr. J.N. Kardile |

| Introduction: |
| Hundreds of filter plants are under design and construction, particularly in the developing countries for the supply of filtered water in cities and villages. As the conventional filter plants are fairly costly in their construction and maintenance. An intensive research is going on all over the world for the development of cheaper filter plants with the use of improved pretreatment methods including the use of coagulant aids and higher rates of filtration through dual and multimedia filters. In addition to this extensive automation for the various controls in the filter plants are under development in the developed countries to reduce the operational cost. Due to high cost of construction and maintenance in adopting the conventional filter plants, many towns and villages particularly in the developing countries cannot afford to adopt the same for their water supply schemes. Thus the design and construction of simple and cheap high rate water treatment plants is a challenging problem before the Engineers in the world. |
