Alternative Processes

Chlorophenols (CPs) are toxic nonbiodegradable pollutants. In recent decades, several alternative processes for the treatment of these compounds have been investigated. Advanced Oxidation Processes (AOPs) are some of the most promising technologies. Among them, the UV-based AOPs [O3+Fe(II)+UV, photo-Fenton, UV+Fe(III), UV+H2O2, photocatalysis and photolysis] have previously been studied for the degradation of 2,4-dichlorophenol (DCP) in an aqueous solution at laboratory scale. In this paper, these techniques are compared and kinetic constants and pseudoquantum yields are estimated. O3−+Fe(II)+UV and photo-Fenton seem to be the most effective. To study scale-up of these processes from the laboratory to a pilot plant operating with sunlight, equivalent photocatalytic experiments were carried out in such installations. The results are promising and show trends similar to those obtained in the laboratory with lamps. The data obtained have been used to calculate some scale-up factors, which have been employed to make a rough estimation of the amount of waste water that can be treated by the solar AOPs studied. The results obtained are encouraging and prove the feasibility of this type of technology.

Coagulation Process

Tar water acquired in the process of biomass gasification has been pre-treated in the process of the standard coagulation. The influence of the dose of chosen coagulants and pH of the running process on the effectiveness of waste water treatment has been specified. The most purified samples underwent a secondary treatment in the process of advanced oxidation with the Fenton's reagent, in order to evaluate its abilities and desirability of this method in the process of a coagulation. The analysis of the process' conditions influence on its effectiveness has been conducted. What is more, the evaluation of the validity of combining the coagulation process with the advanced oxidation in the treatment of tar water coming from the biomass gasification has been made.

Recent Developments

Soil pollution has become a substantial environmental problem which is amplified by overpopulation in different regions. In this review, the state of the art regarding the use of Advanced Oxidation Processes (AOPs) for soil remediation is presented. This review aims to provide an outline of recent technologies developed for the decontamination of polluted soils by using AOPs. Depending on the decontamination process, these techniques have been presented in three categories: the Fenton process, sulfate radicals process, and coupled processes. The review presents the achievements of, and includes some reflections on, the status of these emerging technologies, the mechanisms, and influential factors. At the present, more investigation and development actions are still desirable to bring them to real full-scale implementation.
