Abstract
Methods and systems are disclosed for optimization of coagulation and/or flocculation in a water treatment process. According to exemplary embodiments, samples are taken from an aqueous liquid and the samples are monitored with an imaging device to capture visual data of particles dispersed or suspended in the liquid. The particles are classified into particle types based on the visual data and a particle size distribution indication is computed for each classified particle type. The particle size distribution indication is then compared to a predetermined particle size distribution value, and in response to a difference detected, dosage of at least one coagulation and/or flocculation agent in the water treatment process can be adjusted.
