Granular activated carbon (GAC) is extensively used as a purifying material for water treatment globally as of 2026. From purifying industrial wastewater to municipal drinking water, GAC can provide a much higher quality of water than would otherwise be feasible.<\/p>\n\n\n\n
Through this article, our experts at Austro Carbon thought of guiding you through the fundamentals of GAC and its applications. This will help you make an informed decision as to why you should consider it in your water treatment, too.<\/p>\n\n\n\n
Think of this as a multi-purpose workhorse within the activated carbon network. It is presented as granules that are hard and irregularly shaped. It ranges from approximately 0.2 to 5 mm in diameter, very much like coarse grains you can visually and physically see and touch. This particular type of activated carbon is created from high-quality raw materials such as wood, coconut shells, etc., that are then carbonized and activated, forming uncountable microscopic pores.<\/p>\n\n\n\n
Unlike Powdered Activated Carbon (PAC), which is a fine powder under 0.18 mm that disperses in liquids, GAC maintains its structure. You pack it into columns or beds for fixed operations, making it ideal for your continuous processes rather than one-off batch treatments.<\/p>\n\n\n\n
This particular type of carbon is the best choice if you require a filter medium that can endure extremely harsh conditions. It has a particularly high surface area compared to other bulk materials, with excellent adhesion properties to adhere strongly to organic compounds, chlorine, pesticides, and heavy metals like mercury. <\/strong><\/p>\n\n\n\n In\u00a0addition,\u00a0it\u00a0is\u00a0also\u00a0very\u00a0strong\u00a0mechanically\u00a0and\u00a0is\u00a0able\u00a0to\u00a0resist\u00a0deterioration\u00a0when\u00a0exposed\u00a0to\u00a0high\u00a0flow\u00a0rates;\u00a0therefore,\u00a0it\u00a0is\u00a0going\u00a0to\u00a0give\u00a0you\u00a0a\u00a0long\u00a0life\u00a0for\u00a0your filter media\u00a0and also produce\u00a0less dust\u00a0than other products.
