Week 9

This week we evaluated how various pumping speeds affect the dosing. It appears first that the dosing is variable across pumping speeds. For slow speeds, we’ve determined that dosing is fairly inconsistent. For medium and fast speeds, the dosing is fairly consistent, especially for our original non-drilled out Venturi device. Our next approach will be to actually use chlorine to determine the dosing across our devices and then come to a conclusion on which device is best to use moving forward in our pilot tests this summer. Furthermore, we’re hoping to begin using a flow meter because our current classification of pumping speed is highly arbitrary so our data may not be as consistent as  we could be getting.
