(#8616) Can MBBR STPs which use UV lamps instead of hypochlorite for disinfection be considered chemical free STPs?


Kindly guide us on whether MBBR STPs can be considered as chemical free STPs if they do not use hypochlorite and instead use UV lamps for disinfection.


Chemical free Sewage Treatment Plant(s) (STPs) refers to systems which rely on natural processes for wastewater treatment. The MBBR system as a whole does not fall under this category.
