Which solids treatment method removes 100% of the pathogens, water, and organics?

Incineration is the method that effectively removes 100% of pathogens, water, and organics from solids. This process involves burning the waste materials at high temperatures, which not only destroys pathogens but also reduces the volume of solids significantly. The high heat ensures that any organic material is combusted, resulting in ash as the final byproduct, and thus eliminates both pathogens and organic components.

In contrast, aerobic digestion utilizes microorganisms to break down organic matter, but it does not achieve complete removal of all pathogens or solids, leaving some residue. Filtration is a physical separation process that may reduce pathogen levels but does not guarantee their complete elimination. Ponding, which involves holding wastewater in ponds for treatment, may allow for some pathogen reduction through natural processes but is not as effective as incineration in achieving total removal. Therefore, incineration stands out as the definitive method for achieving a complete breakdown of pathogens, organics, and moisture in solids treatment.
