Activated Carbon Filters

Activated carbon filters with high porosity are crucial among commonly employed industrial adsorbents for environmental pollution control. Commercially available activated carbons are derived from various sources such as wood, peat, lignite, coal, charcoal, bone, coconut shell, rice husk, nutshell, and oil products through diverse activation processes.

The term “activated carbon” encompasses a range of carbonaceous adsorbents characterized by large crystal structures and extensive internal pore networks. These products are safe for human health, featuring remarkable porosity and internal surface area. The porous structure allows activated carbons to attract molecules and ions from solutions to their inner surfaces, earning them the designation of adsorbents.

The carbon particle surface attracts and adsorbs gas, liquid, and solid substances, forming a thin film layer. Activated carbon is preferred as an adsorbent due to its attractive surface for specific substances and its expansive surface area capable of holding significant amounts of material.

Pore size is a crucial parameter influencing pollution removal effectiveness. Determining pore size aids in understanding carbon properties, with pores varying in shape from cylindrical to conical.

Types of Activated Carbon Filters

Activated Carbon Filters come in various forms, including powdered activated carbons, granulated activated carbons, and activated carbons in pellet form. Chemical activation yields powdered activated carbons, widely employed in contemporary cleaning processes. Granulated and pellet forms, produced through gas activation, find application in gas purification, with notable efficacy in wastewater treatment systems. Both granulated and powdered activated carbons demonstrate excellent performance in eliminating organic and inorganic substances.

These activated carbons have a longstanding history of success in the purification of biologically treated wastewater and wastewater containing organic industrial wastes.
