Chemical activation is achieved by degradation or dehydration of the raw material structure (mostly wood-based). The carbon within a carbon filter needs to be periodically changed to maintain optimum filtration, and to avoid moisture and particle build up clogging the system. It is important to understand the volume of air being filtered, and how this will affect carbon replacement. According to DESOTEC, an activated carbon manufacturer, “Activated carboncan be manufactured from a wide variety of raw materials such as coal, coconut, and wood. The production processes of activated carbon may be divided into chemical and thermal processes, both at elevated temperatures.”

Activated carbon filters are safe in every way. An activated carbon filter is used for medical, environmental, cosmetic, residential, and agricultural applications. An activated carbon filter is safely used for water purification, air purification, gas purification, and life support systems. What are Activated Carbon Filters Used for? Activated carbon filters are made up of small bits of carbon that have been processed to be extremely porous. In fact, activated carbon is so permeable that 1 gram of this substance can have a total surface area of 500m 2 (5,400 sq. ft.) or more.

Odour Control and VOC Abatement for Sewage & Wastewater Treatment

Depending upon the application and the adsorbed contaminants' nature, AKS series filter sheets may be regenerated by rinsing with clean water in the forward direction. However, the achievable regeneration efficiency must be determined by monitoring filtrate quality. Medical Applications: Activated carbon is used in medical applications to treat overdoses and poisoning as well as alleviate problems like indigestion and diarrhea. In regards to what does an activated carbon filter do exactly, it removes gases, chemical vapors, and volatile organic compounds (VOCs) from indoor air so it’s healthier to breathe and smells fresher. Mercury Removal: When activated carbon is infused with halogens or sulfur, it can trap mercury gas and remove it from the air. You can think of it like this: adsorption is best used for air filtration while absorption is better for liquids.

Activated carbon powder has been used in filter sheets for many years, primarily for colour removal from low grade sugar syrups and for chlorine removal from water to be used in soft drinks production. Analytical Chemistry Applications: Activated carbon is often used to purify solutions of organic molecules and chemicals. Seitz Filter Sheets have a long-lasting tradition of more than 130 years in the depth filtration market and play a key role within the Pall depth filter portfolio. The invention of Seitz filter sheets at the beginning of the 19th century and the market introduction of the Seitz-EK Sheet by Theobald Friedrich and Georg Seitz was one of the most important pioneering achievements in the "cold-sterile" bottling of beverages without the necessity of heat treatment without noteworthy quality losses. No need for use of secondary filters and filter aids to remove activated carbon from the process fluid

Granular Activated Carbon (GAC):This consists of large pieces of activated carbon but has a smaller external surface area than other types of activated carbon.
