Week Two Completed Tasks
Preparing for Filter Construction
We put nails in a salt water bath on this day and began researching optimal sizes and quantities for the final water filter design.
4/17 Final sizes confirmed, suppliers found - filter housing will be 3' long by 1" diameter clear aquarium tubing with an outer sheath to keep it stabilized and shielded from light. About 2 quarts of fiberglass will be needed, weight unknown, we'll use fiberglass insulation. Hydraulic loading rate for testing is 2 m/h, meaning a flow rate of ~900 ml/h, feeding is to be 1% of this and constant (outflow tube opening will be constricted to achieve this). Final quantity of nails unknown.
4/19 First signs of rust on test nails, larger quantity soaked for use in final design. Final quantity still unknown.
4/22 Water container obtained for sample collection on Thursday, 4/25. One gallon to be used by group
