摘要

The brilliant performance of Phanna sector in India on one side has established it as a trustworthy destination for manufacturers but at the same time has raised concerns over the catastrophic depletion of safe environmental conditions in the country. Whilst they have brought prosperity, employment And • global recognition, in the hind sight t hey have also given very large side-effects. Chemicals that are discharged from these industries have been found to be in volumes that are manifolds higher than the safe guidelines. Many companies strictly adhere to the safe discharge norms but majority of them have facilities which have tremendous scope for Improvement. In such cases flzuncials dictate the extent to which the treatment plants are deployed. Cost effective techniques, smaller treatment plants and alternative treatment methods have been introduced. However the use of nature's own creation in cleaning the contaminants from water is not a new practice. Since ancient times many trees and herbs have been used for this purpose, prominent of which are Drumstick (Moringa oftlferal, Peepal (Fiats reilgiosa) and Neem (AzhadfrachfaIca). They have the ability to bring down the pH, TDS & TSS thereby increasing the usability of water. The exact feasibility of Drumstick trees is being evaluated.
