The aim of this investigation was to find out how properties of a flocculation agent and flocculation kinetics affect the morphology of fibre flocs and how dewatering of a fibre suspension may be attributed to floc morphology. Fibre flocculation, analysed in terms of floc size, mass fractal dimension, floc strength, and the kinetic constant of flocculation, was measured with a digital image ana...

this research was done in order to determine the basic criteria for “tehran oil refinery effluemt treatmentunit” to prove the feasibility of the application of powdered activated carbon in aeration zone of activated sludge system. the main stages of this research included: determination of qualitative and quantitative characteristics of raw wastewater preparation of two pilot scale units of act...

When an individual experiences a mental health crisis, Virginia law permits that individual to be detained up to 48-hours plus weekends and holidays for evaluation and emergency treatment under a temporary detention order (TDO). After 48-hours, authorities must hold a civil commitment hearing. The four possible hearing outcomes are dismissal of the commitment petition, mandatory outpatient trea...

The effect of impeller type and shear rate on the evolution of floc size and structure during shear-induced flocculation of polystyrene particles with aluminum sulfate is investigated by image analysis. One radial flow (six-blade Rushton turbine) and two axial flow (three-blade fluid foil, four-blade 45° pitch) impeller configurations are examined. The steady state average floc size is show...
