“…The amount of ash depends on the raw material used. According to the laboratory records of the author and supported by the literature [7,9], typical values are 2-3% by weight for coconut-shell-based activated carbon, 5% by weight for wood-based activated carbon and 8-15% by weight for carbon-based activated carbon.…”

“…The determination is carried out using a pycnometric method with pore-penetrating gases or liquids whose molecules are small enough to completely penetrate the micropores. The pycnometer is a measuring device for determining the density of solids or liquids by weighing [9].…”

“…The measurement with helium is more accurate because it penetrates deeper into the pores. The true densities of commercially available activated carbon are around 2.0-2.1 g/m 3 [9].…”

“…Basic data for the design are summarized in Table 4. The recommended filtration speeds (m/h) for common liquids are as follows: drinking water (5-15; sometimes up to 20), municipal wastewater (5)(6)(7)(8)(9)(10)(11)(12), landfill leachate (0.3-2), process water (10-20) and industrial wastewater (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Indicative values for empty pipe residence times (minutes) are as follows: drinking water (5-20; sometimes up to 30), municipal wastewater (15-40), landfill leachate (40-60), process water (5-40) and industrial wastewater (10-60).…”

Activated carbon has many potential applications in both the liquid and gas phases. How activated carbon can help practitioners in industry is explained. This practical teaching article introduces the first part of the special issue on Recent Advances in Applied Activated Carbon Research by providing a handbook explaining the basic applications, technologies, processes, methods and material characteristics to readers from different backgrounds. The aim is to improve the knowledge and understanding of the subject of activated carbon for non-adsorption experts such as professionals in industry. Therefore, it is written in a comprehensible manner and dispenses with detailed explanations to complex processes and many background references. This handbook does not claim to be complete and concentrates only on the areas that are of practical relevance for most activated carbon applications. Activated carbon and its activation and reactivation are initially explained. Adsorption and relevant processes are outlined. The mechanical, chemical and adsorption properties of activated carbon are explained. The heart of the handbook outlines key application technologies. Other carbonaceous adsorbents are only introduced briefly. The content of the second part of the special issue is highlighted at the end.
