“…Nonylphenol polyethoxylates are oxidised to NPs under anaerobic conditions (i.e. in sewer system, sediments and during anaerobic processes at WWTP), they are known to be unstable and toxic in water environments, and exhibit estrogenic activities 3 . Nonylphenol polyethoxylates are transformed by microorganisms to more toxic compounds, e.g.…”

The results of the study of removal of nonylphenol, octylphenol and their ethoxylates from real industrial and municipal wastewater are presented. Industrial wastewater was pre-treated by coagulation with FeCl 3 and adsorption on zeolite, before discharging into municipal sewer system. Their removal efficiencies in primary sedimentation tank of municipal WWTP were very low. From the practical point of view, the highest and the most significant removal efficiencies within the whole WWTP were observed for nonylphenol and nonylphenol ethoxylates. Dominancy of abiotic mechanisms of alkylphenols removal follows from adsorption measurements. Activated sludge cultivated in lab-scale extended aeration tank accounted for relatively high adsorption affinity to these substances. Activated sludge sampled from municipal wastewater treatment plant (MWWTP) receiving industrial wastewater containing alkylphenols accounted for very low adsorption affinity to these pollutants. Significantly higher removal efficiency of octylphenol ethoxylates was observed with the O 3 /granular active carbon (GAC) process compared to the ozonation process alone. Lower toxicity impact of intermediates and products of ozonation treatment on Vibrio fischeri was measured in comparison to the O 3 /GAC process. Actually, the municipal WWTP effluent discharge concentration values complies with EQS values, including nonylphenols.

“…[4,5,6]. These compounds enter the aquatic environment from industrial and municipal effluents [7] because the existing wastewater treatment plants (WWTPs) were designed to remove mainly inorganic substances, nutrients and pathogens, not trace levels of organic refractory compounds [8]. Therefore, more efficient water treatment methods and sustainable water reuse technologies are needed.…”

Preparation of Novel Fe Catalysts from Industrial By-Products: Catalytic Wet Peroxide Oxidation of Bisphenol A

et al. 2017

Biomass-based carbon residue (CR) was used as a support material for iron catalysts to degrade bisphenol A (BPA) in catalytic wet peroxide oxidation (CWPO). According to the results, CR and Fe/CR catalysts are suitable materials for CWPO. The Fe catalysts were prepared by either incipient wet impregnation or wet impregnation methods with an iron chloride solution. The specific surface area of the prepared catalysts was 17-91 m g , and it remained the same after the oxidation experiments. The CWPO experiments were carried out batch-wise at c (

“…Currently, the available conventional treatment technologies have inherent challenges and shortcomings with respect to applications, design, effectiveness, and economics (Gultekin and Ince 2007;Tsai et al 2009). Biological treatment, for instance, does not produce satisfactory result especially when treating industrial waste-water.…”

Water pollution through natural and anthropogenic activities has become a global problem causing short-and long-term impact on human and ecosystems. Substantial quantity of individual or mixtures of organic pollutants enter the surface water via point and nonpoint sources and thus affect the quality of freshwater. These pollutants are known to be toxic and difficult to remove by mere biological treatment. To date, most researches on the removal of organic pollutants from wastewater were based on the exploitation of individual treatment process. This single-treatment technology has inherent challenges and shortcomings with respect to efficiency and economics. Thus, application of two advanced treatment technologies characterized with high efficiency with respect to removal of primary and disinfection byproducts in wastewater is desirable. This review article focuses on the application of integrated technologies such as electrohydraulic discharge with heterogeneous photocatalysts or sonophotocatalysis to remove target pollutants. The information gathered from more than 100 published articles, mostly laboratories studies, shows that process integration effectively remove and degrade recalcitrant toxic contaminants in wastewater better than singletechnology processing. This review recommends an improvement on this technology (integrated electrohydraulic discharge with heterogeneous photocatalysts) viz-a-vis cost reduction in order to make it accessible and available in the rural and semi-urban settlement. Further recommendation includes development of an economic model to establish the cost implications of the combined technology. Proper monitoring, enforcement of the existing environmental regulations, and upgrading of current wastewater treatment plants with additional treatment steps such as photocatalysis and ozonation will greatly assist in the removal of environmental toxicants.
