It does this through adsorption. Adsorption means contaminants stick to the surface of activated carbon. There are two main ways this happens: physical adsorption and chemical adsorption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >How Adsorption Works<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Activated carbon attracts pollutants like a magnet. The surface has many pores and special groups. These features help catch different molecules. Pollutants stick to the surface and stay there.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" >Adsor\u00e7\u00e3o f\u00edsica<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Physical adsorption uses natural forces between molecules. No chemical reaction is needed. The pores give activated carbon a big surface area. Small molecules stick to the surface by van der Waals forces. This works best for dissolved organic compounds and gases.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p><a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/heycarbons.com\/activated-carbon-liquid-phase-adsorption\/\">Micropores trap small molecules<\/a>.<\/p><\/li><li><p>Mesopores let medium molecules reach inside.<\/p><\/li><li><p>Macropores help large molecules move in.<\/p><\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Physical adsorption removes many pollutants. It is simple and works well for lots of contaminants.<\/p><\/blockquote>\n\n\n\n<h4 class=\"wp-block-heading\" >Chemical Adsorption<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Chemical adsorption uses chemical bonds to hold pollutants. Activated carbon reacts with certain contaminants. The surface has functional groups that form bonds with metals or complex organic compounds. This process is stronger than physical adsorption. It removes pollutants that are hard to catch.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>Chemical adsorption works for metals like chromium and lead.<\/p><\/li><li><p>Functional groups help form strong bonds.<\/p><\/li><li><p>The process can change the pollutant, like reducing Cr(VI) to Cr(III).<\/p><\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<colgroup><col style=\"min-width: 25px;\"\/><col style=\"min-width: 25px;\"\/><\/colgroup><tbody><tr><th colspan=\"1\" rowspan=\"1\"><p>Mechanism\/Factor<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>Descri\u00e7\u00e3o<\/p><\/th><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p><a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9925964\/\">Electrostatic interactions<\/a><\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Activated carbon attracts negative ions at low pH.

You do not have to throw away so much used activated carbon. Regeneration also helps the environment by keeping waste out of landfills. Choosing to regenerate makes your wastewater treatment more sustainable and keeps things running smoothly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Regeneration Methods<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There are different ways to regenerate activated carbon. Each way works best for certain pollutants and situations. <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/heycarbons.com\/activated-carbon-regeneration-guide\/\">The table below lists the most common methods<\/a>:<\/p>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<colgroup><col style=\"min-width: 25px;\"\/><col style=\"min-width: 25px;\"\/><col style=\"min-width: 25px;\"\/><\/colgroup><tbody><tr><th colspan=\"1\" rowspan=\"1\"><p>M\u00e9todo<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>Descri\u00e7\u00e3o<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>Application<\/p><\/th><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Water washing<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Uses water flow to remove water-soluble organic matter.<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Granular and columnar activated carbon for less contaminated water treatments.<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Thermal regeneration<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>High-temperature removal of organic pollutants.<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Deep regeneration in industrial waste gas and wastewater treatment.<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Chemical regeneration<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Uses acid-base solutions for desorption of pollutants.<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Activated carbon used for adsorption of specific pollutants.<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>Biological regeneration<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Microbial decomposition of organic pollutants.<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>Suitable for long-term operation in wastewater treatment.<\/p><\/td><\/tr><\/tbody>\n<\/table>\n<\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" >Thermal<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Thermal regeneration uses very high heat, between 700\u00b0C and 900\u00b0C. You put the used activated carbon in a special furnace. The heat burns away the trapped pollutants. This brings back most of the carbon\u2019s cleaning power. It is good for tough pollutants in factory wastewater. But it uses a lot of energy and may not remove all chemicals, like PFAS.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" >Qu\u00edmica<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Chemical regeneration uses acids or bases to wash out pollutants. This method is good for certain contaminants that react with chemicals. It does not use as much energy as thermal regeneration. But you must be careful with the chemicals to stay safe and protect the environment.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" >Biological<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Biological regeneration uses helpful microbes to break down pollutants inside the activated carbon. This method is good for long-term use and saves energy. It is also better for the environment. You need to take care of the microbes so the process works well.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Lifespan and Limitations<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">How long activated carbon lasts <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.waterandwastewater.com\/activated-carbon-in-wastewater-treatment\/\">depends on water quality and your goals<\/a>. You should test it often to know when to regenerate or replace it. Most activated carbon can be regenerated a few times, but not forever.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Regeneration is one of the biggest challenges for cost and the environment. Thermal regeneration uses a lot of energy and may not destroy all PFAS. Sometimes, harmful byproducts are made. After regeneration, activated carbon usually gets back only 70-85% of its original power. This means you will need to replace it sometimes.<\/p><\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">There are some limits to regenerating activated carbon:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>Carbon loss: <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/eureka.patsnap.com\/report-activated-carbon-adsorption-pfas-trace-organics-removal-selectivity-and-regeneration\">You lose 5\u201310% of the material each time<\/a> because of breakage, dust, or gas.<\/p><\/li><li><p>Contaminant restrictions: Regeneration does not work for some things, like mercury and lead.<\/p><\/li><li><p>Energy and resources: Thermal regeneration needs high heat. Chemical and biological methods need careful handling or good microbe management.<\/p><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">You need to think about these problems when you choose to regenerate. Knowing the limits helps you plan the best way to use activated carbon in your wastewater treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" >Advantages of Activated Carbon in Treatment<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" >Alta efici\u00eancia<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Activated carbon can take out many pollutants that other methods miss. It works well for dissolved contaminants that biological treatments cannot remove. For example, biologically activated carbon can get rid of <a target=\"_blank\" href=\"https:\/\/tankecarbon.com\/pt\/water-treatment-activated-carbon\/wastewater-treatment-activated-carbon\/\">over 90%<\/a> of some medicines and personal care products. Sand filters only remove some of these substances. Activated carbon gives better results when water has tough chemicals.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Activated carbon is a good choice for cleaning water very well.<\/p><\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, ozonation removes more pollutants than activated carbon. But activated carbon is still important for removing many harmful substances. It helps lower the total amount of particles in water. This makes water safer to use and release.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Versatilidade<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Activated carbon works for many kinds of wastewater and pollutants. It <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.huameicarbon.com\/it\/application-of-activated-carbon-in-wastewater-treatment\/\">removes organics, pigments, heavy metals, and odorants<\/a>. Its large surface area and special pores help trap different molecules. You can pick <a target=\"_blank\" href=\"https:\/\/tankecarbon.com\/pt\/granular-activated-carbon\/\">carv\u00e3o ativado granular<\/a> or powdered activated carbon. Granular activated carbon works for many pollutants. Powdered activated carbon works fast for certain problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here are some pollutants you can remove with activated carbon:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>Organic pollutants<\/p><\/li><li><p>Metais pesados<\/p><\/li><li><p>Colorants<\/p><\/li><li><p>Odores<\/p><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This means you can use activated carbon in city and factory wastewater treatment. You can change the process to meet your water quality goals.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Compatibility with Other Methods<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can use activated carbon with other treatment methods for better results. In Powdered Activated Carbon Treatment, you add carbon to biological systems. The carbon grabs compounds that are hard to break down. This <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/en.wikipedia.org\/wiki\/Powdered_activated_carbon_treatment\">lowers chemical oxygen demand<\/a> and reduces toxic effects. Using both biological and carbon adsorption makes the treatment stronger.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1385894799001096\">Biological Activated Carbon process<\/a> removes non-biodegradable substances and oxidizes biodegradable ones in the same reactor.
