A water treatment plant has three identical horizontal shaft flocculation tanks. Each tank is composed of three stages with size of 4 m depth, 14.1 m length and 15 m width. G value of each stage is 40 s-1, 30 s-1 and 20 s-1. Mean water temperature is 15°C (μ = 1.139×10-3). What are the power requirements for flocculation stages in a single flocculation tank. And Is the flocculation tank in an efficient way?

( Plant's average flow rate of 300,000 m3/d, Design criteria: G · t 104 ~ 105, Detention time 20~30 min )

Discuss in detail how coagulation and flocculation are performed at a drinking water treatment plant. Describe how the optimum coagulant dose can be determined to treat fresh surface waters for drinking water supply.

A water treatment plant has 6 settling tanks that operate in parallel (the flow gets split into six equal flow streams), and each tank has a volume of 600m^3. If the flow to the plant is 10mgd, what is the retention time in each of the settling tanks? If, instead, the tanks operated in series (the entire flow goes first through one tank, then the second, and so on), what would be the retention time in each tank?

Two tanks each contain 100 gal of water and tank 2 initially has 50 lbs of salt uniformly dissolved in it. An external flow brings adds 5 gal/min to tank 1 with 5 lbs of salt in it. Tank 1 feeds tank 2 at 10 gal/min, and tank 2 feeds back to tank 1 at 5 gal/min. Finally, an exit stream leaves tank 2 at 5 gal/min. 1) Use Laplace transforms to solve the system of ODEs modeling this system...
