A TO STUDY OF DIFFERENT RESEARCH METHODOLOGY ON CHARACTERIZATION & REUSE OF DRINKING WATER TREATMENT PLANT (DWTP) WASTE ALUM SLUDGE
Keywords:
Alum sludge, dwtp alum sludge, waste alum sludge, p removal technologyAbstract
In this study, Drinking water treatment plant alum sludge produced at water treatment plants and has long been treated as a waste. Aluminum sulphate is the most widely used coagulant in drinking water treatment. Today, large amounts of alum sludge are being produced from water treatment plants all over the world. Drinking water treatment plant alum sludge from a different Drinking water treatment plants were studied for its capacity for removal of phosphorus (P) from synthetic wastewater. Orthophosphate is used as a model pollutant in synthetic wastewater as well as sewage wastewater. Alum sludge from local treatment plants was collected, dried, and processed before use. Batch experiments were performed to determine PO4-P removal under equilibrium conditions. Sludge dose, contact time, and pH were optimized for synthetic wastewater. Adsorption efficiencies’ of P were determined by using Langmuir and Freundlich adsorption isotherm models.
