COAGULATION AND FLOCCULATION

Conventional plants separate coagulation (or rapidmix) stage from flocculation (or slowmix) stage. These stages are followed by sedimentation, and then filtration. Plants designed for direct filtration route water directly from flocculation to filtration. These systems typically have a higher rawwater quality. Conventional plants can have adjustable mixing speeds in both the rapid .
