“…McConnell et al [82] tried to answer the question how single treatment stages in two tertiary WWTPs influenced the elimination (copies/mL) and relative plenty of ARGs (copies/copies 16S rRNA genes). Nine ARG markers, exemplifying resistance to frequently employed antibiotics, as well as one integron gene (intl1) to evaluate ARG mobility capacity, were measured utilizing quantitative real-time PCR (qPCR).…”

Developed control of chemical disinfection techniques is beginning to be progressively significant in order to equilibrate under-treatment (minimal pathogen demobilization) and over-treatment (immoderate consumption of disinfectant and disinfection by-products generation) that way giving great ecological and economic advantages. This work reviews the most recent and pertinent researches in this field of eliminating Antibiotic-resistant Bacteria (ARB) carrying genes (ARGs) during wastewater treatment especially disinfection. Traditional disinfection techniques may not be efficient in demobilizing ARB and the simultaneous liberation of ARB and antibiotics at sub-lethal concentrations into municipal wastewater treatment plant effluent may promote the development of resistance among bacteria in receiving water. The pathway of the influences of diverse disinfection techniques in water and wastewater (chlorination, UV irradiation, Fenton reaction, ozonation, and photocatalytic oxidation) deserves more attention. The impacts of constructed wetlands and nanotechnology on ARB and ARG have to be more explored. As the best available technology, membranes processes should be widely adopted through the world for removing ARB and ARGs from the perspective of reusing treated wastewater as drinking water. These safe barriers against pollutants diffusion in nature merit more technical and economic expansion for their larger industrial application especially in developing countries.

“…The ever-increasing population, the pollution of underground and surface waters, the uneven distribution of water resources and periodical drought, has forced water supplying organizations to look for new resources of water. Utilizing the treated wastewater that is discharged from sewage treatment plants into the environment, has gained more attention as a reliable source (McConnell et al, 2018). Today in many countries the use of treated wastewater and reusing water is an important point in managing water resources.…”

The available research was managed to monitor the physicochemical and microbiological features of treatment plants. The wastewater treatment herb sewage is a straight pollution input source for anthropogenic pollution. The sediment information ideas to an urban drainage trench as a secondary point pollution source while the organotins information highlights the presence of other spread sources, special to this material. wastewater re-use in urban has increased in many realms. The consequences of the study display that among the offered treatments, the best for asepsis and reducing microbial pollution of urban outlet effluent is that of the plus 0.25 weight percent Permanganate filter. Due to the amount of demand and need for the use of wastewater and circulated waters in agriculture, now most of wastewater treatment plants in the IRAN are designed and administered with the goal of reusing the wastewater produced in agriculture. Using wastewater increases the functioning of plants and does not have negative effects on the properties of the soil and its permeability. At the time in numerous cities of the IRAN the urban sewage and surface runoff which leave the cities, are used in farms downstream. The best option for the microbial disinfecting of the outlet wastewater in urban wastewater treatment plants among the treatments presented belonged to the plus 0.25 weight percent of potassium permanganate powder filter treatment. So that the percentage of the elimination of microbial pollution reached more than 99.99% Using this treatment in urban wastewater treatment plants can increase the microbial quality of wastewater to very high values, which can be utilized in farms, nutrition of groundwater resources, entrance to surface waters, Irrigating the green space, use in car-washes, etc.

“…Recently, some of developed countries such as the United States, England, Germany, and Italy have started to examine the negative effects of these pollutants on the environment. Drugs essentially have very strong biological activity, which affects the living organisms (1). In addition, they are highly resistant to biological degradation and are not degraded under normal conditions but require specific reactions under special conditions.…”

Finally, drug compounds enter water resources, and affect the environment (1). Among different drug compounds, antibiotics are the most important group of drugs because these compounds are extensively used for the treatment of various diseases (2).…”

Background: Drugs, especially antibiotics, are one of the serious problems of modern life and the main pollution sources of the environment, especially in the last decade, which are harmful to human health and environment. The aim of this study was to investigate the removal of penicillin G from aqueous solutions using single-walled and multi-walled carbon nanotubes. Methods: In this study, the effect of different parameters including pH (3, 5, 7, 9, and 11), initial concentration of pollutant (50, 100, 150, and 200 mg/l), absorbent dose (0.25, 0.5, 0.75, and 1 g/L), mixing speed (0, 100, 200, and 300 rpm), and temperature (10, 15, 25, 35, 45°C) were investigated. The Langmuir, Freundlich, Temkin, BET, Dubinin-Radushkevich isotherms and adsorption kinetics of the first-and second-order equations were determined. Results: The results showed that the efficiency of single-walled and multi-walled carbon nanotubes in the removal of penicillin G was 68.25% and 56.37%, respectively, and adsorption capacity of the nanotubes was 141 mg/g and 119 mg/g at initial concentration of 50 mg/l and pH=5 with adsorption dose of 0.8 g/L for 105 minutes at 300 rpm and temperature of 10°C from aqueous solutions. Also, it was revealed that the adsorption process had the highest correlation with the Langmuir model and secondorder kinetics, and the maximum adsorption capacity based on Langmuir model was 373.80 mg/g. Conclusion: According to the results, it was found that single-walled and multi-walled carbon nanotubes can be used as effective absorbents in the removal of penicillin G from aqueous solutions.
