Biological Treatment for Industrial Wastewater using Eichhornia Crassipes (Water Hyacinth)

Abstract

One of the major problems faced by mankind today is of water pollution. There are various methods available for treatment of waste water. The conventional and mechanical methods of treatment of industrial waste water quite expensive and are thus uneconomical for industries of lower turnover rate.  The search is for economical and efficient methods. Use of vascular plants for pollution abatement is recent trend. The present work is directed towards the use of aquatic plant Eichhornia crassipes i.e., Water hyacinth for treatment of industrial waste and the objectives of work are to study feasibility of treatment, number of days required for the treatment, effect of operating tank depth, effect of pre-treatment and effect of Nutrients by observing change in various physical, chemical and biological parameters.
