| Abstract | ||||
| This study conducts a critical analysis of iron removal from water and groundwater quality assessment in El-Kharga Oasis, Egypt, using a combination of dolomite treatment and aeration. Groundwater is vital for irrigation in arid regions like El-Kharga but often has high iron content, which risks soil and irrigation system integrity. The research introduces an innovative approach to reduce iron concentrations, with preliminary water quality assessments indicating iron levels above Food and Agriculture Organization (FAO) irrigation standards. Controlled experiments conditions of 2 L aqueous solution containing 25 mg L-1 Fe determined the optimal dolomite dosage and aeration time for effective iron removal. Results showed the treated water’s pH and electrical conductivity were ideal for irrigation, though high turbidity and iron emphasized the need for treatment. Chemical analysis revealed acceptable alkalinity and sodium hazard levels, with essential plant nutrients like calcium and magnesium present. The study concludes that dolomite-aeration treatment significantly improves water quality, offering a sustainable solution for irrigation management in dry regions. Statistical analyses affirm the method's effectiveness, providing a feasible option to enhance agricultural water quality, crucial for the sustenance of desert communities. | ||||
