h2. {toggle-cloak:id=Challenges} Challenges

{cloak:id=Challenges}
* High load of data input could cause computer crash.
* The refraction of light due to the shape of the tube would skew the images captured.
* The 2D images would not do justice on 3D environment of settling tube. Smaller flocs could hide behind bigger flocs and it would be difficult to do trajectory analysis.

h2. {toggle-cloak:id=Promising} Promising Tool!
{cloak:id=Promising}

* Can observe settling velocities of high percentage of particles
* Can filter particles by size and get particle size and velocity distributions
* Should be able to build up statistics that we can relate to flocculation efficiency
* Could complement turbidimeter as method of determining extent of flocculation
