In terms of activated carbon materials, R&D personnel have improved the specific surface area, porosity, and adsorption performance of activated carbon by improving production processes and formulas. For example, the use of new activators and activation methods can prepare activated carbon materials with higher adsorption capacity and faster adsorption speed, which greatly improves the purification effect of activated carbon filters. At the same time, for different pollutants, activated carbon materials with specific adsorption properties have been developed, such as activated carbon specifically for removing heavy metal ions, activated carbon specifically for adsorbing volatile organic compounds, etc., making the application of activated carbon filters more accurate and efficient.

In terms of filter structure, designers continue to optimize the structure of activated carbon filters to improve their filtration efficiency and service life. For example, a multi-layer filtration structure is used to combine different types of activated carbon materials, which can remove multiple pollutants in water at the same time; a new filter element structure is used to increase the contact area between activated carbon and water or air, and improve the adsorption efficiency; an automated control system is used to monitor the operating status of the filter in real time, realize intelligent backwashing and filter element replacement, and extend the service life of the filter.

In terms of filtration technology, innovative filtration processes continue to emerge, such as dynamic filtration, countercurrent filtration, and the combination of membrane filtration and activated carbon filtration. These new processes not only improve the purification effect of activated carbon filters, but also reduce operating costs and energy consumption. For example, the process of combining membrane filtration with activated carbon filtration can first remove macromolecular substances and suspended solids in the water through membrane filtration, and then remove small molecular organic matter and residual chlorine in the water through activated carbon filtration, which not only improves the purification effect, but also prolongs the service life of the activated carbon filter element.

Wide application cases highlight the excellent performance of activated carbon filters

Urban drinking water purification project: In some cities in Europe, due to the aging of urban water supply pipelines and other reasons, there are a certain degree of residual chlorine, organic matter, heavy metal ions and other pollutants in drinking water. In order to improve the quality of drinking water, the local government uses large activated carbon filters to purify urban drinking water. After being treated with activated carbon filters, the pollutants in drinking water have been effectively removed, the water quality has been significantly improved, and residents can drink safe and healthy water with confidence.

Pharmaceutical factory wastewater treatment: The pharmaceutical industry is a highly polluting industry, and its production process produces a large amount of wastewater containing pollutants such as organic matter, antibiotics, and heavy metal ions. A pharmaceutical factory in the United States uses activated carbon filters to treat its wastewater. First, the suspended matter and macromolecular organic matter in the wastewater are removed through a pretreatment process, and then the wastewater is deeply treated through an activated carbon filter. After the treatment, the concentration of pollutants in the wastewater is greatly reduced, meeting the environmental emission standards. At the same time, the recycled water resources can also be used in other links in the production process, realizing the recycling of water resources.
