Econovel Co., Ltd.’s flagship product is the **iPDA-250A Automatic Coagulant Dosing System with Floc Analysis**. Using optical technology, the system analyzes the growth of flocs formed during the water treatment process in real time and automatically optimizes the coagulant dosage by integrating raw water turbidity and sedimentation basin water quality data. It enables stable chemical dosing and water quality management even during periods of rapid changes in raw water quality, such as the rainy and flood seasons. The system also monitors floc formation and issues an alarm when coagulant dosing fails, helping to prevent chemical dosing accidents.
