The influence of velocity gradient on properties and filterability of suspension formed during water treatment
Original language description
This paper deals with the influence of the global velocity gradient G (in the range of 28?307 s-1) on properties of suspension (size and structure) formed during water treatment. Furthermore, it describes the influence of these properties on separation using depth filtration (filtration velocities of 3 and 6 m h-1). The methods of image and fractal analysis were used to determine the aggregate size and structure, respectively. The experiments were conducted in a pilot plant (a mixing tank and a rapid gravity sand filter) with ferric sulphate used as coagulant. The experiments confirmed that with an increasing velocity gradient the aggregate size decreased; the aggregate size distribution narrowed (suspension was more homogenous); the fractal dimensionD2 increased (aggregates were more compact) and the fractal dimension Dpf diminished (aggregates were more regular). The smallest and most compact aggregates (d 60 ?m and D2 = 1.9) formed at G > 200 s-1 displayed the best filterability wi
