Elimination of micropollutants from municipal wastewater by adsorption on powdered activated carbon and separation by innovative precoat filtration

Spinning Submerged Filter Adsorber versus Packed Bed Adsorber for the Continuous Removal of Antibiotics from Wastewater with Activated Carbon

“…A municipal WWTP running with a hydraulic retention time of 30 min can achieve a target-oriented reduction of trace substances by dosing 30 mg/L of fine PAC particles of 10 µm directly to the wastewater. Dosage into the post-treated wastewater is more effective than into the biological treatment unit [23]. Recently a spinning submerged filter adsorber has been proposed to remove wastewater contaminants that combines the use of adsorbents and filtration, works with small particle size adsorbents under complete mixing conditions, and can operate with particulate matter.…”

Unraveling competition versus adsorbability of dissolved organic matter against organic micropollutants onto activated carbon

“…The existence of organic micropollutants (OMPs) is a major concern for human health and the aquatic environment [1,2]. Adsorption onto activated carbon is widely used for OMP abatement in water purification [3][4][5]. The adsorption affinity of OMPs towards activated carbon depends on a variety of factors, including activated carbon properties (pore structure, surface chemistry), OMP molecular characteristics, and adsorption competition due to dissolved organic matter (DOM) [6][7][8].…”
