Simultaneous Waste Water Purification via Photocatalysis and Seed Germination
ABSTRACT
Preliminary results of our study related to simultaneous waste water purification by photocatalytic degradation of organic impurity (Methylene Blue dye) and its effects on seed germination are presented here. It is interesting and important to know that complete degradation of the dye occurs within 2 hours and does not adversely affect the seed germination process. It is concluded that waste water purification by photocatalysis and seed germination (agriculture) can be carried out simultaneously, opening a way for advanced agriculture.
