Percentage Removal

This study demonstrates the phytoremediation prospective of Typha latifolia (TL) and water Hyacinth (WH) in industrial wastewater treatment. A comparative study was done to evaluate the percentage removal of turbidity (Tu), electrical conductivity (EC), color (Col), iron (Fe), copper (Cu) and zinc (Zn) from industrial wastewater by using Typha latifolia and water Hyacinth with respect to uptake time and with different concentrations of industrial wastewater. The experimental results showed that Typha latifolia has performed extremely well in removing the 90.03% Tu, 82.31% EC, 95.98% Col, 92.01% Fe, 87.78% Cu and 75.81% Zn from 20% industrial wastewater during 16 days of experimental period. Results also showed that the maximum percentage removal of selected heavy metals by Typha latifolia follow the order Fe > Cu > Zn from 20 % industrial wastewater at 16-day experiment. Water Hyacinth showed best result for removing 64.15% Tu, 62.19% EC, 50.29% Col, 54.15% Fe and 70.17% Cu from 15% industrial wastewater during 12 days experiment but it has performed extremely well in removing the 85.97% Zn from 20% industrial wastewater after 16 days of experimental period.

Simultaneous Nutrient Removal

More stringent effluent criteria will be required in the near future for the so-called priority substances listed in the Annex of the European Water Framework Directive (WFD) 2000/60/EC. This includes heavy metals, volatile and semi-volatile organic substances, pesticides and polychlorinated biphenyls. The Fraunhofer Institute suggested FHI values for these substances in water. National Dutch legislation, the Vierde Nota WaterHuishouding (NWH) introduced in 1998 ‘maximum tolerable risk concentrations’ (MTR). These include requirements for nutrients: Ptot<0.15 mg/l and Ntot<2.2 mg/l. The MTR values are being used until the FHI values become effective. Investigation into possible effluent polishing techniques is required in order to reach these objectives. During pilot research with tertiary denitrifying multi-media and biological activated carbon filtration at the WWTP Utrecht in the Netherlands, simultaneous nutrient removal to MTR quality was observed. Furthermore, simultaneous removal of heavy metals, 17β-estradiol, bisphenol A and nonylphenols to extreme low concentrations by denitrifying activated carbon filtrated is achieved.
