This study concerned with the leaching Alum(LA) from surface water treatment solid waste using different concentration of sulfuric acid. Surface water treatment solid waste samples was collected from representative samples from a certain station as usual in all stations ,the factors affecting on productivity of leached Alum (Al2O3 ) such as the sulfuric acid concentration, pH, flow rate of H2SO4, and reaction time were studied , the obtained Alum is used in drinking water treatment and sewage waste water treatment from one side and to get rid of water waste from the other side. The experimental results revealed that there are no significant variations in water quality between treatment with LA from solid waste and commercial Alum (CA) running coagulant and all comply with regulations, the removal percentage of sewage waste water pollutants TSS, COD and BOD reached 100, 82, and 79% respectively using LA respectively, while the removal percentage of sewage waste water pollutants TSS, COD and BOD reached 85,81 and 100% respectively using CA. Finally, the prepared Alum from solid waste should be used as low cost coagulant in water treatment for its quality in coagulation beside its uses in an environment protection.
