The primary treatment of sewage water involves
- A sludge digestion
- B aerobic bacterial activity
- C anerobic bacterial activity
- D filtration and sedimentation
Answer & Solution
Correct Answer
(D) filtration and sedimentation
Step-by-step Solution
Detailed explanation
(D) filtration and sedimentation,
Primary sewage water treatment entails filtration is sedimentation of solid waste inside the water. The purpose of primary treatment is to settle material by gravity, removing floatable objects and reducing the pollution to ease secondary treatment.
