Abstract:
This project deals with the filtration of waste water using corncobs 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. Thus, a matter of primary concern is the economical and efficient utilization of these corn cobs for a purpose. As they are porous, they can be used as water filtrates. This project discusses about a low cost water filtration system which uses corncobs as filter materials in its various forms. 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.
