Primary Treatment Process

Primary Water Treatment Process

Primary Water Treatment process consists in removing large suspended organic solids. this is usually accomplished by sedimentation in settling basins.
The liquid effluent from primary treatment, often contains a large amount of suspended organic materials, and has a high BOD ( Biological oxygen demand )  ( about 60 % of original)


Sometimes, the preliminary as well as primary water treatments are classified together, under primary water treatment.
The organic solids, which are separated out in the sedimentation tanks ( in primary water treatment) are often stabilized by Anaerobic decomposition in a Digestion Tank or incinerated. the residue is used for land fills or soil conditioners.
