Abstract
Water pollution is a burning issue nowadays but this may be overcome by using phytoremediation technique. In order to investigate the potential of phytoremediation of meat processing wastewater, the pot experiment (using Pongamia pinnata) was carried out. The complete randomized block design was setup and pots were irrigated with different concentrations of wastewater i.e. 25% (T1), 50% (T2), 75% (T3), 100% (T4) and control (T0). The plant physiological characteristics revealed positive signs. Plant height, leaf number, fresh weight and dry weight increased by 23%, 30%, 98% and 7.2%, respectively. Maximum photosynthetic rate, stomatal conductance and transpiration rate was observed in T2 which was 46.2, 0.2 and 1.6, respectively. Lower concentrations showed better productivity due to adequate nutrients while in higher concentration growth retarded. This experiment concluded that P. pinnata is efficient specie for phytoremediation of meat processing unit. P. pinnata may serve as a cost effective approach towards wastewater re-use and mitigation of water pollution.
