Effluent quality refers to the characteristics and composition of wastewater or treated water released from an industrial or municipal treatment facility. It is evaluated based on various parameters such as pH, temperature, chemical oxygen demand (COD), biological oxygen demand (BOD), suspended solids, and the presence of contaminants like heavy metals or pathogens. Ensuring high effluent quality is essential for environmental protection, public health, and regulatory compliance, especially when the effluent is discharged into natural water bodies or reused in industrial applications.
Primary treatment of wastewater is the second stage. It comes after preliminary treatment. Primary treatment removes solid materials and organic matter from wastewater. This stage uses processes like Sedimentation Sedimentation uses gravity to separate solids from wastewater. In primary wastewater treatment, it happens in a large tank called a sedimentation tank. Wastewater enters this tank, […]
