This paper reports on the development of hybrid water treatment technologies that take advantage of the attributes of activated carbon adsorption and Fenton oxidation through the development of novel hybrid process schemes: i) a continuous Powdered Activated Carbon (PAC) – Fenton process using a dilute suspension of PAC in a well-mixed reactor vessel connected to a submerged ultrafiltration (UF...

Biological treatment, due to the formation of hazardous chemicals remove organic compounds such as dimethyl sulfoxide (DMSO) and N, N-dimethylacetamide (DMAC), has limited potential. Advanced oxidation processes (AOPs) are regarded a viable alternative for treating molecules containing carbon-hydrogen bonds that cannot be broken down by traditional physico-chemical methods. In this investigatio...

Micropollutants have emerged as a new challenge to the scientific community over the past decade. This chapter discusses the occurrence of various micropollutants in landfill leachate. Phthalic acid esters (PAEs) are one of the most investigated compounds in landfill leachate and are therefore given special focus in this chapter. The potential treatment options for these micropollutants are dis...

The use of AOPs (Advanced Oxidation Processes) for the treatment of industrial wastewaters has increased during the last years. The process efficiency depends on the treatment conditions (temperature, pH, reagent dosage etc.) and it is very difficult to predict it because the reaction mechanisms are strongly affected by the mutual relationship among these parameters and the wastewater compositi...

The effects of the Fenton reagent on recycled unbleached pulp in the absence and presence of a model chemical contaminant, the p-hydroxybenzoic acid (HBA), were studied. In the absence of HBA, the Fenton system clearly modified the chemical and papermaking properties of the pulp. The kappa number was reduced and the specific light absorption coefficient was increased, indicating lignin modifica...

This research was focused on the investigation of the efficacy of advanced oxidation processes (Fenton, ozonation and UV/H2O2) for decolorization of reactive azo dye (Blue CL-BR) using bleach wastewater as possible source of H202. All the experiments were performed on the laboratory scale set-up. The results showed that colour removal efficiencies by UV or bleach (H2O2) alone were not so effici...
