Vedclass · Answer

(D) Assertion $(A)$ is correct because $STP$s are designed to treat wastewater by removing contaminants through physical,chemical,and biological processes.Reason $(R)$ is incorrect because,at the end of the $STP$ process (specifically after secondary treatment),the water is treated to remove flocs (masses of bacteria associated with fungal filaments). The treated effluent,which is released into water bodies,is largely free of these flocs. Therefore,the water does not 'possess' flocs at the end of the process; rather,flocs are removed during the sedimentation phase.

$A$ - $STP$ (Sewage Treatment Plants) purify sewage.
$R$ - In the end of $STP$,the water possesses flocs.
