During the Spring 2015 Semester, the Fabrication sub-team is addressing four separate projects. The first is the development is the testing of the weir system, which is oriented towards use in the plant as a way to adjust flow rate through the plant. The development of the weir system and the creation of a scale model were the biggest accomplishments of last semester's Fabrication team. Along with this project, the Fabrication is designing a large-float valve to be used to join and regulate flow from the storage tank to the first main tank in the Aguaclara plant. In addition, the team is looking to create a DOM sensor and a floc hopper probe to be used in Aguaclara plants.
The DOM sensor may measure absorbance of a long wavelength (perhaps red) and a short wavelength (blue or UV). The absorbance of the long wavelength light will be a measure of the absorbance due to suspended solids. The absorbance of the short wavelength light will be a measure of the absorbance due to suspended solids plus DOM. The absorbance due to DOM can thus be obtained by subtracting the absorbance of the long wavelength from the absorbance of the short wavelength.
