PARTICLE REMOVAL IN FLOC BLANKET CLARIFIERS VIA INTERNAL FLOW THROUGH POROUS FRACTAL AGGREGATES
… The mechanism of primary particle removal in floc blanket clarifiers was characterized via size-based performance curves obtained from light blocking particle counters that measured the effluent of a laboratory-scale floc blanket clarifier treating synthetic raw water. Particle capture was …

Removal of organic colour from natural surface waters by coagulation and floc blanket clarification, with an investigation of the effects of the addition of Kaolin as a process aid
… coagulation of organic colour, and secondly in floc blanket clarification. The dissertation then presents an investigation of the effect of the addition of clay-kaolin-as a process aid, in floc blanket clarification of South African organically coloured natural surface waters.

Modeling Powdered Activated Carbon Performance in Membrane Filtration Systems
… of the membranes, and the recirculation to a floc blanket reactor after backwash results in significantly lower carbon dose for a given adsorbate removal.

Reduction of odors associated with chlorine dioxide applications to drinking water
… powdered activated carbon (PAC) enmeshed in alum floc in laboratory-constituted water and Po River water. A high level of PAC (50 mg/L) was required to effect good removal. A simulated floc-blanket clarifier effectively removed high levels of chlorite (>5 mg/L) from drinking water for long periods …

The catalytic oxidation of manganese in water treatment clarification processes
… of dissolved manganese in water treatment floc blanket clarifiers has been studied. The removal mechanisms may be broadly classed as adsorption and oxidation. Adsorption of manganese (II) occurs rapidly and is completed in less than five minutes under conditions prevailing in a floe blanket …

Chlorine dioxide by-products in drinking water and their control by powdered activated carbon
… evaluated CI02 removal by PAC enmeshed in a floc blanket in a pulsed-bed, solids-contact clarifier. An average of 27 percent of the CI02 was removed when the PAC dose was 10 mg/L PAC and 57 percent when it was 20 mg/L PAC. Chlorate was not removed by PAC, but the concentrations could be …
