Zero liquid discharge (ZLD) is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle. It ensures that there will be no discharge of industrial wastewater into the environment with zero liquid waste.

Hospital sewage contain a large variety of substances like pharmaceuticals residues, pathogens, chemical reagents, radionuclide, and other harmful matter. As it is very complicated effluent it must be treated like industrial effluent.

Many Communities and Industries across the world are intensely exploring natural bioremediation tool as an important source to clean up waste water. Bioremediation mainly uses naturally occurring microorganisms and other aspects of the natural environment to treat the wastewater of its nutrients.
