(100a) Monitoring and Classification System for Water Recycling
We demonstrated the CWMS for a variety of wastewater sources including laundry, kitchen, and latrine. We then validated our models with additional samples from other water sources such as wastewater treatment facilities to demonstrate the robustness of the system. After specifying all of the components, we designed a prototype system. Principal component analysis was used to classify water and draw distinctions between surface non-potable water, greywater and blackwater. We were also able to eliminate the need for dedicated COD, BOD5, turbidity and chlorine sensors by processing spectroscopic data with chemometrics.
