Study on synergies in the removal of organic micropollutants using combined iron electrocoagulation and irradiation

This study analyses the removal of organic micropollutants (OMPs) through iron electrocoagulation in the presence of solar radiation. Methylene Blue (MB) dye has been considered as a contaminant which is removed by the action of highly reactive oxygen species (ROS) formed as intermediates during electrocoagulation (charge dosage, CD = 30 C/L and...

Ozone-Based Regeneration of Granular Zeolites Loaded with Organic Micropollutants

The removal of organic micropollutants (OMPs) in the aquatic environment is crucial to avoid health hazards. Zeolites have been confirmed as a selective adsorbent and can effectively remove target OMPs. To achieve sustainable application of adsorbents, regeneration of zeolites is required. <br/>The objective of this study was to investigate the...

On-site Regeneration of Acetaminophen Loaded Zeolite Granules by Applying Gaseous Ozone Based Oxidation Process

The wide application of pesticides, pharmaceuticals and personal care products cause an increasing contamination of aquatic systems. Adsorption by zeolites is a promising process to remove target organic micro-pollutants (OMPs) selectively from water bodies. In order to have a sustainable adsorption process, restoring the adsorption capacity of...

Improving Organic Micropollutant Removal of Activated Carbon by Pre-treatment with Zeolite Adsorbent

Activated carbon (AC) is commonly used in drinking water treatment plants (DWTPs) to remove organic micro-pollutants (OMPs), and it is effective in adsorbing a wide range of OMPs. However, its adsorption efficiency can be affected by natural organic matter (NOM). NOM is a complex matrix and widely exists in water bodies. During the drinking...

The Freshwater Factory: removing organic micro-pollutants with ozonation

Removing organic micro-pollutants (OMPs) can enable wastewater reuse to alleviate pressure on fresh water sources. This research aims on the prediction of OMP removal efficiencies by ozonation and biofiltration based on experimental data sets and/or modelling. Comparison of experimental data on average OMP removal of three different studies from...

Organic Micropollutant Treatment by Pre-Ozonation and Activated Carbon

Inadequate treatment of wastewater effluent is one of the major point sources of pollution of organic micropollutants (OMPs) into aquatic environments. Wastewater treatment plants need to be upgraded to reduce OMP contamination. Recently, the combination of pre-ozonation and granular activated carbon (GAC) filtration has been proposed as a...
