Freundlich Equation

The adsorption removal of benzalkonium chloride disinfectant by granular activated carbon is discussed. The adsorption isotherm of benzalkonium chloride was expressed by the Freundlich equation. A significant correlation was found between the amount of benzalkonium chloride adsorbed in less than 1000 ppm of equilibrium concentration and the micropore volume of activated carbon. As for the adsorption rate, a change in intraparticle diffusiveness was found with increasing adsorption ratio. No significant correlation between the values of intraparticle diffusiveness and the properties of activated carbon was found. It was concluded that the micropore volume of activated carbon was the dominant factor in the adsorption removal of benzalkonium chloride by granular activated carbon.

Activated carbon, also known as activated charcoal, which is crude form of graphite, substance which is used lead pencils. Activated carbon is widely used in dye removal and also has other applications. Activated carbon has high surface area, adsorption capacity, and high adsorption rates from the gas or liquid phases. Activated carbon is also used in air purification, chromatography, energy storage, electrode materials for li-ion batteries biosensors, hydrogen storage, immobilizing the biomolecules. Therefore, activated carbon has wide applications. It is used in gas separation, solvents recovery and as catalyst. It is also used in waste-water treatment plants to remove the organic pollutants from the drinking water. For most of these applications, activated carbon is prepared from many resources by implementation of different chemical methods. The Activated carbon can also be prepared by different raw carbon resources like lignite, peat, unburnt coal and biomass wastes such as wood, sawdust, sugar cane bagasse, coconut shell, coffee beans, oil-palm stone, and Rice husk. Ligno-cellulosic waste materials, paulownia wood, pomegranate seeds, cattail, olive-tree, jatropha hull, bamboo, orange peel, thevetia peruviana, ramie, grape stalk, pine apple waste biomass, and almond shell. Activated carbon is also produced by pyrolysis of physic nut waste. Activated Carbon, prepared from all these sources, have high surface area, adsorption capacity, high adsorption rates for liquid gas separation, adsorption. Activated Carbon is widely used in waste water treatment to remove the pollutants. This review explores some of methods to prepare the activated carbon from different local sources reported by many researchers in recent years.

The efficiency of two possible intensification methods of activated sludge waste water treatment (pure oxygen activation and activated carbon addition) were compared. Experiments were carried out in laboratory scale equipment with variable reactor volume (maximum capacity 20,0 dm3, settling tank vol. 15 dm3). In order to detect even minor differences, we operated completely identical units in parallel runs, with one representing a traditional system as reference. A model sewage of industrial character, diluted milk, was used as influent and in the course of activated carbon intensification experiments an anion-active detergent was added as a poorly biodegradable model material to be removed mainly by adsorption. Reactor loads were gradually increased - from low values to overloading - by decreasing the dilution of milk or by reducing reactor volume. The effects of different intensification methods on the effluent pollution level (COD value and anion-active detergent content) and on the settling properties of sludge were examined as a function of loading. The efficiency of both intensification methods was found to be increasing with increasing loading. Comparison of the two systems showed activated carbon intensification to be more efficient in the removal of soluble COD and extremely useful in the elimination of a poorly biodegradable material.
