OPTICAL SENSING DEVICE AND METHOD IN A LIQUID TREATMENT SYSTEM

OptikTechnik LLC, Milwau...

1. An optical sensing and control device comprising:a light source emitting a light beam;
an optical component in communication with the light beam to receive the light beam from the light source, the optical component driven by a motor for the optical component to rotate about an axis relative to the light beam;
a control assembly in communication with the motor to rotate the optical component at a selected plurality of revolutions per minute about the axis such that the optical component is configured to move the light beam in a plane, the plane extending into an area such that the light beam interacts with particles in the area producing a scattering of the light beam; and
a photodetector in communication with the particles within the plane, the photodetector configured to generate image data in response to the scattering of the light beam while the optical component is driven about the axis.

AUTOMATED DOSING SYSTEM AND METHOD WITH LIGHT PROFILING FOR WASTEWATER FILTRATION SYSTEM

OptikTechnik LLC, Milwau...

1. 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, the light beam forming a scan line on the compound solution,
a photo-detector capturing an image of at least a portion of the scan line 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 a characteristic of the scan line from 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.
