Week Seven Completed Tasks
Turbidity and Flow Rate Measurements
The turbidity measurements were 16.26 (river water) and 1.69 (filtered river water). In class we also decided that everyone would let their filter run dry and let it remain dry for 12 hours before feeding it again. We also attempted to measure the flow rate.
Flow rate had decreased to nil. I suspect this is due to iron filings fusing together as they rust, forming an impenetrable layer. I broke up this layer by poking it, and flow rate has returned to normal. New flow rate measurement to come.
