  • MathCAD Automated Materials List (Adela)
  • Fixing Small MathCAD code issues (Adela & Reiko)
    • Switch programs that refernce nominal diameters to calculate areas, hopper drain, width to depth ratio for sed drain. (Adela)
    • Valve sizes: sludge drain, hopper drain?, floc drain ,(Adela)
  • Flocculator design, after you figure out how many baffles that are ideal for a channel, figure out how many actually fit and put them in uniformly. Ports that go under the walls? Do the engineers care? That affects how the tank is drained (Reiko)  (Reiko)
  • Floc Drain Algorithm (Reiko)
  • Sludge drain width needs to be adjusted (Reiko)
    • Check needs to be added so that the length below the slope is at least 2.5cm
  • Gap between slope plates and wall needs to be calculated (Reiko)
    • Number of ports/plates in sed tank are overestimated (why?) The number of ports/plates were calculated based on the max sed length. Changed to be calculated based on the actual length now.
    • Plates stay at 30cm
  • Slope plate length need to be adjusted so the opposite corner rests against the wall (the length will decrease) Floc Drain Algorithm (Reiko)

AutoCAD

(Heather R, Sara & Heather H)

  • Update Code with MathCAD variable Changes (could be a task spilt between people taking the programs below). (Heather R & Heather H)
  • Check and Debug Flocculator Program(Heather R)
  • Check and Debug Entrance Tank Program (Heather H)
  • Debug basic Sed tank program (just the outer tank walls (exclude the inner pieces)(Sara)
  • Scripts to Draw Drain Valves
  • Drop chimneys
  • Add 15cm false bottom
    • Slopes and the rest of the fill are then drawn as one element
  • Lamella need to be adjusted to incorporate pipe frame

Later Tasks

  • Stream Line Sed tank code into modules
  • Change pipe Drains into Channel Drains
  • Change Drop pipe chimmmeys connecting inlet channel to sed manifolds to rectanglular channels
  • Adjust the sed bays program to build dividing walls and be accurate

Tasks From Honduras

  • Drain to have minimum dimension of 10cm 12cm (OD 4" pipe = 12cm)
    • Exit pipe that connects to valve needs to fit under the drain plate
    • 3" gate valves are used in Honduras
    • Check that 3" or 4" pipe will fit without alteration under the drain
    • Count number of Valves needed
  • Walls between bays are 15cm thick
  • Send drawing of new drain cover
  • Floc Ports are cut in the tops of the channel dividing walls
  • Lamella Pipe Frame Table 1.5" pipe sitting on ledge, possible concrete frame instead
  • Thickness of floc baffles: 4cm
    • Baffle dimensions/area needed to determine thickness (sent to Tamar)
  • For Gracias:
    • AutoCAD drawings for all 3 designs--concrete layout OK
    • Chemical Storage Tank Dimensions
  • For Altima:
    • Send out Design
  • Complete Design for Alquteca (same as 4 communities)
  • Automated Excel Spreadsheet of Plant Details
