MATERIALS
metal wire —>rusting?
-will stainless steel not rust? We’re not sure, but think it would, has it been used in the past in wastewater systems or supported biofilm growth?
-thin vs thick plastic
--type of plastic? polyethylene may be cheapest/easiest
-rubber
-silicone? —> may resist biofilm growth
-fiberglass
Ideas about our initial test:
we will want to test how much volume of water is on the string at a given moment
volume=flow rate*(time water droplet spends on string)
just use pump to get water flowing down a single string, think about volume as a place to start. Eventually, we will want to test how close the system could be to a PFR (plug flow reactor) so that each string is an equally valid path and we avoid preferential flow.
