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.
