Flocculation is often used in solid-liquid separation processes to ensure removal of fines. Average packing density in sediments and degree of clarification are easily accessible by optical detection with light. For a more comprehensive understanding of separation process and packing behaviour of sediments more detailed information on local particle concentration, i.e. concentration profiles are necessary. To this end measurement of X-ray transmission profiles can be used.
The paper presents examples of flocculation of mineral suspensions (quartz, clays). Settling and dewatering behaviour at gravity and in centrifugal field as function of acceleration was characterized by STEP-technology measuring light transmission...
