| Abstract | ||
| Industrial water systems produce enormous volumes of effluent wastewater. Properly controlled and managed reuse can provide significant additional resources of good quality water for arable agricultural purposes. Evaluation of using treated wastewater for watering were carried out through the study of accumulation of heavy metals in plant. Four treatment methods, (dilution, filtration, chemical, physico-chemical) were used in treated wastewater effluents with adjusted pH value (5.5, 6.5 and 7.5). The concentrations of Zn, Mn, Cu and were determined by Atomic Absorption Spectrometer (AAS) depended on APHA standard Fe method. The result shows methods using (Physico-chemical, chemical using 20 mg/L (Al2(SO4)3 and dilution at 25% ratio methods, with adjusted pH value at 7.5 showed reduction in concentration of heavy metals in seed and fruit planted plants with treated effluents with limited maximum levels residue in fruit depended by World Health Organization The minimum allowable accumulation in plants approved by the World Health Organization (WHO) compared with other treatments. In conclusion treated effluents proud beneficial aspects for ability and potential in using for agricultural purposes. | ||
