Abstract: Water hyacinth was obtained from Tirunelveli pond and it was used to remove dye from effluent water. Water hyacinth plant remove the rhodamine dye which was present in the dye water and the quality of treated and purified water was analyzed by APHA method. The present study clearly indicates that the purified water was more suitable for culturing of both plant (pennisetum glaucum) and fish (oreochromis niloticus) by analyzing the survival and the growth rate. Water hyacinth showed better antimicrobial activity against selected pathogens such as Pseudomonas, E.coli, Micrococcus, Proteus vulgaris, Bacillus subtilis; Micrococcus luteus; Escherichia coli. The present study also showed that the test plant (mung bean seeds) was grown well due to the nutrients which are present in the Compost made from water hyacinth than the Control. Protein profile of plant (pennisetum glaucum) and animal (Oreochromis niloticus) grown in this study indicates that there was a similar fraction was observed in test and control. In this present study water hyacinth used as Bio adsorbent, best antimicrobial agent and Natural manure.
