- make sure G¿ is high enough for entire system (minimum of 20,000)
- make sure G is not so big it is going to break up flocs (flocs will be smallest in this tank though, and small flocs are harder to break)
- perhaps it would be best to use multiple baffle spacings
- The space above a down baffle should be 1.5b under a condition of no headloss
- The first baffle should be an underflow
- try to maintain a design that will allow 3 baffles to be cut from 1 12 ft sheet of polycarbonate
Constraints:
- width of tank (w): 98 cm
- flow rate (Q): 500 gpm
- K: 3
- Height at end of flocculator(h0): 140 cm (this is a bit confusing because of the sloped floor. The height at the end of the tank is actually 155 cm, but at the beginning the tank is only 145 cm. I set the water height to be 140 cm at the end after headloss, this ensures that the water level at the beginning of the tank will be less than 145cm)
- Headroom (hroom): 5 cm
- Ratio between baffle spacing and the height of the horizontal channel (hratio): 1.5
