Rapid Mix
The rapid mix research project's goal is to determine if inadequate mixing in the rapid mix unit is responsible for the residual turbidity at the end of the AguaClara treatment process. This can be accomplished by adding some additional turbidity after the rapid mix process to see if those colloids have a significant effect on the settled water turbidity. If a large fraction of the colloids that didn't go through the rapid mix end up in the effluent, then it suggests that colloids that aren't properly exposed to aluminum hydroxide in the rapid mix process could also end up in the effluent. The next phase of this research would be to experiment with different rapid mix designs.
- energy dissipation rates
- residence times
- sequence of mixing units where each mixing unit has an alum feed
