Automated dosing system and method with light profiling for wastewater filtration system

A flocculation dosing system comprising:

• a mixing chamber configured to receive wastewater and flocculant material, the mixing chamber configured to mix the wastewater and the flocculant material together to form a compound solution;
• a conveyor that receives the compound solution, a liquid content of the compound solution decreasing as the conveyor moves the compound solution from a first end of the conveyor toward a second end of the conveyor;
• and
• a surface sensing assembly in communication with the conveyor, the surface sensing assembly including
• a light source directing a light beam toward the compound solution on the conveyor,
• a photo-detector capturing an image of the light beam interacting with the compound solution, and
• a controller coupled to the light source, the photo-detector, and at least one actuator, the controller configured to determine an indication of surface topography of the compound solution based on the image, the controller also configured to control the at least one actuator to adjust a characteristic of the compound solution based on the indication of surface topography.
