Mathematical model for phytoremediation of pulp and paper industry wastewater

A mathematical model for studying the phytoremediation potential of water hyacinth (Eichhornia crassipes) against pulp and paper industry effluent is developed and analyzed. Initially, phytoremediation potential increased for short time and then leveled off, resulting into consequent pollutant removal, which enabled to calculate logistic differential equation for developing uninhibited growth model. The model developed is applied to some important physico-chemical parameters (pH, EC, BOD, COD, TSS, TDS, Na and K) of the effluent treated using cost effective phytoremediation technology.
