IMPROVED METHOD OF WASTE WATER TREATMENT THROUGH EICHHORNIA CRASSIPES

摘要

In the present invention, method of removing amount of metal like cadmium, chromium, zinc and lead from waste water using plants of the family Pontederiaceae is disclosed. In order to accomplish this, Eichhornia Crassipes dry mass is utilised o provide adsorbent base. Metal like cadmium, chromium, zinc and lead present in the waste water are allowed to adsorb onto the surface of dry powder of Eichhornia Crassipes thus restricting the presence of heavy metals into the domestic waste water and industry effluent that could harm aquatic lives when released to water resources.
