Kanchipuram is named as silk city due to more number of dying and printing industries
located in and around this place and it is also a traditional industry in Kanchipuram. These dyeing
industries present in Kanchipuram area and the villages surrounding are under the great danger of
subsurface water pollution with the chemicals of dyes, even though it is treated. So it is a necessity to
retreat the effluent disposed by dyeing industry for preventing the contamination of ground water. The
aim of the project work is to understand and analyze the adsorbent ability, the adsorbent being palletized
Pungamia Glabra leaves, for the treatment of the effluent from the dyeing industry. This setup also
includes a trickling bed that is prepared with cut Pungan leaves sieved to a specific size and is introduced
as a secondary treatment by providing a natural green leaf surface. The treated effluent sample of known
quantity is trickled into the bed by means of a perforated pipe. Then the filtered effluent is collected,
analyzed and compared with the Bureau of Indian Standards (BIS).
