With reference to the Paper "Step$-$by$-$step design and calculations for water treatment plant units" on e$-$learning and your class notes, slides and text book, provide a conceptual design and sequence of unit operations and processes for a water treatment plant showing calculations and unit dimensions for coagulation, flocculation, softening and disinfection as a minimum. Following is the water quality profile of the source river water:
