“…Residual H2O2 should be removed from treated wastewater before discharge or reuse. To avoid the presence of residual H2O2 in the treated water, two main approaches were implemented, namely the addition of relatively low concentrations of H2O2 (which can be completely consumed during the process) and filtration through activated carbon [38]. The addition of the catalyst MnTACN to H2O2/UV has no negative effect on Vibrio fischeri bacteria.…”

In this work, the treatment efficiency of advanced oxidation processes H2O2/UV enhanced by the addition of a manganese catalyst complex (MnTACN) was investigated on a model dye solution and a real dye-house effluent. The experimental results were evaluated in terms of absorbance (A) and total organic carbon (TOC) reduction. The major degradation products of the model dye solution were identified by high resolution gas chromatography/mass spectrometry analyses. In addition, the toxicity of the final reaction solution after H2O2/UV/MnTACN treatment to Vibrio fischeri bacteria was determined. The results showed that the addition of the H2O2/UV/MnTACN system at in different concentrations of the catalyst solution increased enhance the decolourization rate compared to H2O2/UV for both the model dye solution and real dye-house effluent.

“…In the present study, the hybrid process of sono-electro-Fenton efficiently reduced the toxicity of the effluent after the decomposition of the cefixime under the optimal removal conditions. Results of studies conducted by other researchers have also shown the effective role of advanced oxidation processes in reducing the toxicity of pollutants using different species of organisms (24,25). In a study, Dirany et al evaluated the toxicity of sulfamethoxazole by bioassay using microorganisms and noted that the toxicity of the effluent treated with the electro-Fenton process was reduced by about 75%, compared to the inlet solution (26).…”

The aim of this study was to determine the toxicity of cefixime in the inlet solution and effluent treated with the sono-electro-Fenton process using standard strains of microorganisms. This research was performed as an experimental study, which was conducted on a laboratory scale. The standard strains of Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) were used for bioassay. First, the stock solution of 1000 mg/L containing Cefixime was prepared, and for each bacterium (gram-positive and gram-negative), 5 samples from the inlet solution of the reactor and 5 samples from effluent treated with the sono-electro-Fenton process were collected under optimal conditions. Finally, each sample was transferred to 10 mL of sterile lactose broth, and a loop of E. coli or S. aureus was dissolved in each sample. Toxicity changes were investigated by calculating the percentage of growth inhibition. The results showed that after 10 hours, the growth rate of both bacteria in the control and the effluent samples was higher, while the growth of bacteria in the inlet solution was lower and had higher toxicity. Based on the results of the study, the toxicity rate for E. coli was reduced from 70% in the inlet solution to 9.3% in the effluent (86.7% reduction in toxicity), and in the case of S. aureus, it was diminished from 25.3% in the inlet solution to 7% in the effluent (72.3% reduction in toxicity) after 10 hours. Based on the results of the present study, bioassay using microorganisms is an effective and useful method to study changes in the toxicity of cefixime.

In recent years, the pharmaceutical field has significantly achieved magnificent progress owing to the necessities of human health and life; however, it also led to drastic environmental issues. The existence of pharmaceuticals in water bodies, which could cause adverse effects on human beings and environment, rose up distress worldwide. The pharmaceutical components found in water bodies have mainly two origins: manufacturing procedures in pharmaceutical industry and common usage of pharmaceutics. The essence of pharmaceutical wastewater (PWW) is intricate, including large amount of organic matter, high salt, microbial toxicity, and non-biodegradable. In sight of water scarcity means, it is essential to figure out and expand techniques for pharmaceutics derived wastewater in water management. Nevertheless, numerous treatment methods have been established to serve pharmaceutical wastewater including biological treatments, membrane technologies, hybrid technologies, advanced oxidation processes, absorption methods, etc. Recently, metal organic frameworks (MOFs), metallic ions clusters linked with organic bridging linkers, have been utilized in number of uses such as storage, separation, sensing, catalysis, adsorption, and many others. The viability of MOFs toward wastewater treatment (WWT) for various pollutants is fundamentally because of the extreme porosity, discrete pore structure, and superficial modification. This chapter highlights the origin and treatment of pharmaceutical wastewaters via the utilization of MOFs and their hybrid systems. A brief perception of the future work in the field has also been discussed.
