Secondary procedures mostly remove suspended and dissolved organics. Tertiary strategies realize nutrient removal and even more sprucing of wastewater. Disinfection, the final action, destroys remaining pathogens. The squander sludge generated through treatment is individually stabilized, dewatered, and despatched to landfills or Employed in land apps.
