Week 8 Prototype Update

This week we began to take a more serious look at the math behind our device. Specifically, we are trying to discover (1) if the chlorine dosing is in fact linearly related to the flow rate of the water through … Continue reading

Week 8 Update

So far this week, we tested our three current prototypes to see which one allowed the most consistent dosing of our water supply.  Continuing our simplified testing setup from last week, we measured the ratio of water to chlorine taken … Continue reading

Week 8

This week we continued to test our three prototypes to evaluate the consistency and dosing of each. We are also working to define a mathematical model that describes the dosing of our device. We are interested in better understanding what … Continue reading

Week 7 Prototype Update

This week the prototype team made a new prototype and began the pump corrosion test. We made a new “T” prototype ready for testing. This prototype has the same set up as the venturi based device, but the difference is … Continue reading

Week 7

This week we simplified our testing setup to better understand dosing. Our plan is to fill the IV tube and straighten it on a plank. We then pump a number of times and mark the level of Cl dosed per … Continue reading

Week 7 Update

Our latest development (largely thanks to Kara) has been a simplified testing approach for evaluating how consistently our device doses a given volume of water flowing past it.  We assume that the volume of chlorine entering our water supply is … Continue reading

Week 6 Prototype Update

This week the we helped out with testing the new set up with non return valves on each side of the device. From this we discovered that a significant amount of back-flow actually came from leaking between the pump and pipe connection. … Continue reading
