Vedclass · Answer

(D) In Sewage Treatment Plants $(STPs)$,the term 'effluent' refers to the treated wastewater that is released into natural water bodies (like rivers or streams) after the completion of both primary and secondary treatment processes. $1$. Primary treatment involves physical removal of particles through filtration and sedimentation,resulting in 'primary effluent'. $2$. Secondary treatment (biological treatment) involves the growth of flocs (bacteria and fungal filaments). $3$. After secondary treatment,the mixture is passed into a settling tank where the flocs are allowed to sediment. The sediment is called 'activated sludge',and the remaining clear water is the final effluent,which is safe to be released into water bodies.
