The percentage of suspended solid waste in raw water is removed by coagulation is__________________?
Correct answer: C. 80
- A. 60
- B. 70
- C. 80
- D. 90Hiring An Environmental Sustainability Consultant
Explanation
Coagulation destabilises colloidal particles so they join into larger flocs that settle or are filtered, and conventional treatment removes about 80% of suspended solids at this stage. Students may choose d, 90%, by confusing coagulation alone with the total removal achieved after later sedimentation and filtration.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
