Abstract:
The Fall 2019 Humic acid subteam seeks explore the relationship between optimal coagulant dosages and effluent absorbance. Past teams have tested optimal concentration for removing HA. Based on previous work, the optimal coagulant concentration appears naround 1.5 mg/L. For this semester, the team plans to test more coagulant concentrations and humic acid concentration and find the optimal dosage to lower the absorbance of the effluence. The AccuView spectrophotometer will be used to measure the effluent absorbance and measure the efficiency of removing color. The concentrations of HA and coagulant is set based on the data collected from water plants.
