Dissolved Organic Matter Sensor, Spring 2015

Andres Larraza

Abstract

The Fabrication Subteam was created to address problem that arose in the AguaClara plants that are in operation. The Dissolved Organic Matter (DOM) sensor is a project that was created because in the plants in Honduras. DOM is a contaminant in the water that is present naturally due to leaves and other matter in the rivers being decomposed. The DOM in the water was affecting the required amount of coagulant needed to properly flocculate particulates in raw water by requiring more coagulant. The problem was that there was DOM present and we could not measure it properly. This semester, the objectives for the team are to have a working model that can use the RGB(red, green, and blue) values detected by the Arduino board to calculate the concentration of DOM in the water.. This is a first attempt that AguaClara is conducting
