Demands for higher environmental quality from society and environmental organizations are being absorbed by public and commercial water and sanitation corporations in emerging nations like India. In these nations, wastewater treatment plants are progressively being installed, resulting in a rise in sludge production. Before financing and/or licensing a wastewater treatment facility, certain nations have recently published land application standards that now demand a workable sludge disposal plan. A relationship chart between influent sewage, treatment technique, sludge generation, and disposal alternatives are shown in Figure 4.
