Prototyping a spinning adsorber submerged filter for continuous removal of wastewater contaminants

Adsorption process is widely used for the removal of wastewater contaminants. Classic adsorption units are fixed beds and membrane filtration systems. In this work a novel configuration bench scale spinning adsorber submerged filter proposed. Different prototypes cylindric, truncated cone or prismatic adsorbers were studied using activated carbon different particle sizes GAC (1.5 mm, Granulated), ?GAC (0.475 microGranulated), cPAC (0.237 coarse Powder) as adsorbent, azorubine model adsorbate. High maximum adsorptions per unit mass adsorbent 214, 225 275 mg/g GAC, cPAC, respectively, obtained Langmuir isotherm model. Batch followed pseudo-second order kinetics, adsorbate uptake rate increased with decreasing size. Best was tank equipped rectangular prism prototype all made stainless-steel woven wire 180 mesh Running at 600 rpm filled high concentration (25 g/L), can remove similar rates that use free moving cPAC. Adsorber run in continuous mode works even better where filtered flow exits from central pipe axis. This integrated adsorption-submerged operation offer possibility adding initial dose dosing tank, increasing unit. system also opportunities contaminants materials located separately.
