Adsorption of organic micropollutants by zeolite granules and subsequent ozone-based regeneration

Organic micropollutants (OMPs) that occur in the aquatic environment at trace levels are emerging concerns to society. Domestic wastewater is an important source. OMPs end up in surface water and groundwater via conventional municipal wastewater treatment plants (WWTPs), penetrating drinking water. Comprising pharmaceuticals, personal care...

Removal of organic micropollutants from wastewater effluent: Selective adsorption by a fixed-bed granular zeolite filter followed by in-situ ozone-based regeneration

Organic micropollutants (OMPs) that occur in the aquatic environment are an emerging concern. Adsorption by granular zeolites and regenerating exhausted zeolites by gaseous ozone is an innovative and advanced treatment technology for removing OMPs from wastewater treatment plant (WWTP) effluent. In this study, WWTP effluent spiked with eleven...

Removal of organic micropollutants by well-tailored granular zeolites and subsequent ozone-based regeneration

Advanced technologies to remove organic micropollutants (OMPs) from municipal wastewater have gained much attention over the last decades. Adsorption by zeolites is one of these technologies. In this study, the regeneration performance of well-tailored granular zeolites loaded with OMPs was evaluated. The selected OMPs were categorized into...

Ozone-based regeneration of granular zeolites loaded with acetaminophen

Removal of contaminants of emerging concern (CECs) from municipal wastewater is becoming more and more important. On-site regeneration of exhausted adsorbents can be the key to practical applications. In this study, ozone-based regeneration of granular zeolites loaded with acetaminophen (ACE) was investigated. The adsorption capacity of ACE was...

Simultaneous removal of ammonium ions and sulfamethoxazole by ozone regenerated high silica zeolites

Continuous development of industry and civilization has led to changes in composition, texture and toxicity of waste water due to the wide range of pollutants being present. Considering that the conventional wastewater treatment methods are insufficient for removing micropollutants and nutrients to a high level, other, alternative, treatment...
