-Setup Design Review with Steve/Don

Bio-Experimentation:

Reduction of E. Coli with Moringa Oleifera 10/12/06

Pasted from <http://clearwater-aid.editme.com/biological>

Mark:

Same levels, no concurrent

Flocculation

E.coli still prevalent in the dishes and water

The goal was to see of the Moringa Seeds would deflocculate 

• Notes:
• Increase Turbidity
• Add more samples
• Add SOIL
• Figure Turbidity before experiment

ME Thickness Experiments:

• 3/8 Thickness would just shatter
• Graphical representation of thickness
• Optimize the thickness for flow/per hour
• Using the hydraulic conductivity (h) assumed by former team
• Match with water safety levels and come up with an optimum section of thickness to match water safety standards overlay.
• Fire up more….
• Confirm/disconfirm SEM

Kali/Whitney:

• Achiea: natural wood filter
• Cats tails?: is there any available
• Could a cylinder work?
• Possibility
• Increase Pressure head !

Diana:

• Mineral that can eliminate almost 99% of bacteria (ie Silver)
• Iron-Oxy-hydoxide
• Geohitite
• Can be layered in the filter
• That charge would attract the bacteria and viruses
• Mixing Cow manure in filter?
• Another company:
• Already made this filter, its just more expensive

G:

• Lions Club Meeting
• Oct 31 at 1145pm
• Whitney, Kali, Mark, Nick
• Rehearse presentation

Stuff to do:

• Write at least one "Reflective" practice tool
