Analytical study of use of corn-cob as an adsorbent for treating textile waste-water

The current research deals with the filtration of waste water using corncobs as low cost water filtration systems which are generally used as fuel which creates air pollution and global warming. Corn cobs are one of the most plentiful and important agricultural wastes in maize cultivation. As they are porous, they can be used as water filtrates. As we know before disposing of waste water from industry, the industrial water has to undergo various chemical process which uses large amount of money, which can be reduced to a large extent when replaced by these filters at the source where industrial waste water is produced. With the increasing industrialization, amount of waste water generated is increasing at alarming rate, so with the help of this cost efficient technology, the waste water generated in the industries can be decreased to a large extent at the source itself. The Corn cob is the least utilized part of the maize plant. Having high mechanical strength, rigidity and porosity, corn cob is a suitable absorbent. This enables contaminants like oxides of salts, detergent, suspended particles, colored dyes, oil, grease and some heavy metals to be absorbed on the surface of the corn cobs. Chemical and physical examinations are necessary to make a marketable product out of corn cob and its charcoal to adsorb contaminants from the domestic and industrial effluents.
