Abstract
To avoid the water resource pollution, this study attentively of preparation, characterization of leached Alum (LA), poly aluminum hydroxy sulphate (PAlHSTM) and poly aluminum hydroxy sulphate silicate (PAlHSSiTM), which prepared from activated silica derived from rice husk ash and Alum derived from solid waste resulted from surface water purification plant, as well as applications of these new materials in water and waste water treatment. Representative samples of solid waste were collected the solid wastes of surface water purification station. The factors affecting the output of leached (Alum) Aluminum sulphate (Al2(SO4)3.X H2O as (Al2O3) such as the sulphuric acid concentration percentage, pH, flux rate of H2SO4, and contact time were studied. The obtained Alum is converted to PAlHSTM and PAlHSSiTM which characterized using FTIR, XRD and SEM, then the two new materials were applied in sewage water treatment. The empirical outcome implied that there are no considerable deviations of dissolved ions in water specification that treated either with PAlHSTM or PAlHSSiTM. Both of them conform to international guidelines. Whereas the elimination proportion of the main sewage water pollutants: total suspended solids (TSS), chemical oxygen demand (COD) and biological oxygen demand (BOD) reached 96, 89, and 90%, respectively using PAlHSTM, while the elimination proportion of the last main sewage water pollutants reached 97, 91, and 92%, respectively using PAlHSSiTM. conclusively, the prepared PAlHSTM  and PAlHSSiTM  and from solid waste of water purification plant should be used as a minimal cost of commercial coagulant in sewage water treatment for its quality in coagulation beside its uses in an  environmental impact reducer.
