Cleaning Protocol

After running many sets of experiments, the particles get attached and accumulate in the flocculator tubes, so it's harder to observe what's going on in the tubes and this might contribute to a false effluent turbidity reading. Additionally, if the setup sits too long without any action, particles can build up in horizontal pieces of tubing and any connections.

1. Turn off the Turbidimeter
2. Twist in the plastic stoppers on the tubing before and after the turbidimeter to stop flow from coming into the turbidimeter
3. Follow the directions on the module to open the top
4. Carefully unscrew the vial
5. Leave the top of the turbidimeter vial in a careful place (facing up) while cleaning the vial
6. Rinse out the vial and fill it with clean water
7. Screw the vial back onto the top
8. Wipe the outside of the vial with a Kimwipe to remove all fingerprints and other blemishes
9. Place the top back into the module and into the lock position, unscrew the plastic stoppers on the tubing and turn the turbidimeter on

Remaking the Stock Buckets

The clay and alum stock solutions can get old after no experiments have been running for quite some time. Because of processes like evaporation that we can not control, we can never be sure that the concentrations in the stocks are the same as we made them. If an experiment is going to be started after a long time from the last experiment, than the stocks should be remade in order to make sure that all parameters are the same across all experiments.
