Given its merits, why has advanced wastewater
treatment not been widely adopted?
Introduction:
Advanced wastewater treatment has been used for a variety of purposes such as removing the residual nutrients, unsettled microbes, pathogens, and total dissolved solids from the wastewater that is difficult to be done by conventional secondary or biological treatment.
Various strategies have been used to serve the purpose including filtration (suspended solid particles and microorganisms left unsettled), carbon adsorption (removal of refractory organic compounds like micropollutants), phosphorus removal that exists as orthophosphate, polyphosphate, and organic phosphates, and nitrogen control (ammonia removal).
Several methods such as chlorination, ozonation, and ultraviolet radiation have been used as disinfectants for wastewater treatment.
