| Abstract | ||
| The Alum sludge produced from drinking water purification plants represents a burden in its disposal for several reasons, including the quantities and contents, in another track, the influent of wastewater treatment plants with a large organic load that must be reduced to improve treatment and the specifications of the effluent wastewater, BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) and TSS (Total Suspended Solid) are the main organic loads that present in domestic wastewater. This study aims to investigate the efficiency of chemical treatment of wastewater using dried Alum sludge, hence solving these two environmental problems by using dried Alum sludge to treat the effluent of wastewater plants and enhance its quality. Two different wastewater treatment plants were selected to investigate the efficiency of chemical treatment with Alum sludge. Raw wastewater samples were treated with dried slurry at 1050C. The results showed the reduction efficiency in the Ramla and El-Hawamidia wastewater plants ranging from 97% to 81% for different wastewater pollutants. These results confirmed the potentiality of Alum Sludge from water plants for future application in wastewater treatments. | ||
