Removal of per- and polyfluoroalkyl substances (PFASs) in a,Per- and polyfluoroalkyl substances (PFASs) are persistent and harmful pollutants that can contaminate drinking water sources. This study evaluates the long-term performance of granular activated carbon (GAC) for removing PFASs in a full-scale drinking water treatment plant. It also examines how the flow-rate affects the GAC adsorption capacity and the decline in effectiveness over time. Learn

Activated carbon filters get saturated faster than mechanical filters, though, and require replacement more frequently¡ªevery three months, as opposed to every six to 12 months for mechanical
Microplastic Removal from Drinking Water Using Point-of-Use,Microplastics are tiny plastic particles that can contaminate drinking water and pose potential health risks. This study evaluates the performance of different point-of-use devices, such as activated carbon filters, in removing microplastics from tap water. The results can help consumers and policymakers make informed choices for safe and sustainable water consumption.
Activated Carbon Filter [Carbon Block vs GAC Water Filter
Radial flow GAC carbon filters are designed to work much more like both carbon block and GAC filters. The water flows in a radial direction much like carbon filters. It flows from the exterior of the filter to the inside passing through the bed of activated carbon granules. This means the whole exterior surface of the filter gets in contact
Under-Sink Activated Carbon Water Filters Effectively Remove,Evidence-based solutions are needed to prevent drinking water lead exposure among private well users, but minimal data are available regarding the real-world effectiveness of available interventions like point-of-use water treatment for well water. In this study, under-sink activated carbon block water filters were tested for lead and other

Porous sorbents for the capture of radioactive iodine,Activated carbons impregnated with TEDA. In scientific studies, triethylenediamine (TEDA, C), also known as 1,4-diazabicyclo [2.2.2]octane (DABCO), is the commonest impregnating agent used in activated carbon filters for the capture of radioactive iodine species. TEDA has a melting point and a boiling point of 158 ¡ãC and 174 ¡ãC, respectively
A review on the influence of chemical modification on the
Adsorbents are insoluble porous solids capable of binding liquid or gaseous molecules to their surfaces in a simple and cost-effective method of water treatment. The performance of an adsorbent depends on the chemical and physical properties of the adsorbent surface as well as that of the soluble substances. The chemical modification provides a

The effects of chemical modification on adsorbent performance
The adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface is known as adsorption (Amalina et al., 2022a; Ge et al., 2021).The adsorbate is the substance that is adsorbed, and the adsorbent is a solid on which the substance accumulates (Abdulrahman et al., 2020).

Removal of organic pollutants from produced water by batch
At a PAC adsorbent dose of 0.25 g/100 mL, maximum oil removal efficiencies (99.57, 95.87 and 99.84 percent), COD and total petroleum hydrocarbon (TPH) were identified. Moreover, when zeolite X was used at a concentration of 0.25 g/100 mL, the highest turbidity removal efficiency (99.97%) was achieved.
