The suggested Gt value for design of a flocculation tank is given as $$1.08 \times 10^5$$ with an average velocity gradient of 30 per second. What should be the volume of flocculation tank required to treat 30,000 m$$^3$$/d of water?

A

850 $$m^3$$

B

1000 $$m^3$$

C

1125 $$m^3$$

D

1250 $$m^3$$
