- Various factors influencing adsorption on powdered activated carbon (PAC) used for the removal of organic compounds from water and wastewater have been investigated. Incomplete utilization of adsorption capacity of PAC observed in current technological applications is caused by too short con-tact times of aqueous solutions with carbon particles and the system configuration (adsorption in volume systems with simultaneous coagulation). A new method has been proposed involving application of PAC into the upper layer of a two-layer filter or a middle layer of a three-layer filter during bed fluidization. The extended contact time between aqueous solutions and PAC increases the amount of adsorbate adsorbed on the surface of activated carbon. A comparative studies conducted on adsorption in both volume and column systems confirmed better utilization of adsorption capacity for PAC applied on a filter bed. Two models of PAC adsorption in transient conditions were developed for volume and column systems. Computer simulations confirmed that the adsorption capacity of PAC may be in-creased by several times in column systems with respect to the commonly used adsorption with coagulation in volume systems.
