Its appearance in drinking water needs prior treatment to dispose of safely. Fenton, Photo-Fenton oxidation processes were carried out to degrade 2-Aminopyridine. Parameters like pH, the dosage of Hydrogen peroxide, and Iron are optimized for the effective degradation of a 2-Aminopyridine compound in water. The effect of the initial concentration (10-80) mg/L of a 2-Aminopyridine pharmaceutical compound on degradation was studied. Drug at initial concentration of 10 mg/L, 40 mg/L and 80 mg/L is 100% degraded in 30 mins,45 mins and 120 mins respectively. Similarly, COD removals of 94.6%, 88.6% and 81% were detected at 10 mg/L, 40 mg/L and 80 mg/L of initial drug dosage. The degradation was enhanced by photo-Fenton oxidation. Both the drug degradation and COD reduction were improved by UV-C-assisted photo-Fenton oxidation processes.","PeriodicalId":51911,"journal":{"name":"Journal of Applied Water Engineering and Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45967418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is to compare the performances of three hydrological models (rational method, EBA4SUB, HEC-HMS) and two hydraulic bidimensional models (HEC-RAS 2D, FLO-2D) by using the Volunteered Geographic Information (VGI) data. The comparison between the observed and simulated flood areas showed satisfactorily performance of the EBA4SUB-FLO-2D approach compared to the other approaches. The analysis of the observed and simulated flood depths showed a good estimate using the approaches EBA4SUB-FLO-2D and EBA4SUB-HEC-RAS 2D. The best estimate of the two flood depth approaches is attributed to the hydrological model EBA4SUB in estimating the peak flow. The results demonstrate that the EBA4SUB-FLO-2D modeling approach can provide reliable data for the management of flood risks in the ungauged watersheds of the southwest region of Algeria.","PeriodicalId":51911,"journal":{"name":"Journal of Applied Water Engineering and Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44119268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The BWRO plant is located at the Libyan Center for Solar Energy Research and Studies (LCSERS) in the city of Tajura. The six proposed power plants, backed-up with/out batteries and diesel generator were modeled and simulated using HOMER software. Optimal design configurations resulting from the simulation were then selected based on levelized cost of energy (LCOE) and net present cost (NPC) appropriate to the operating conditions at the site.

Associated constraints with these methods inspired the design of a sequential hybrid system by which higher treatment efficiency and less energy consumption were acquired compared to a conventional system. The hybrid system consisted of an electro-Fenton and an nZVI slurry system working in sequence. Both sub-systems were first optimized using the Response Surface Methodology (RSM), and the hybrid system was then designed accordingly. 94.06% of COD removal was achieved by the hybrid system in only 47.5 min at its optimum condition (CODinitial = 500 mg/L, [nZVI] = 0.9 g/L, and H2O2/Fe2+ = 3.6). Whereas it took more than 75 min for the single electro-Fenton system to acquire similar efficiency. GC–MS analysis also supported the superiority of the hybrid system over the conventional one.","PeriodicalId":51911,"journal":{"name":"Journal of Applied Water Engineering and Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46343156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has frequently been neglected for various reasons, viz. near-impossible direct measurement, simplification of the model, and non-existence of the hydro-meteorological data. Hence, baseflow is computed for the Ramganga river basin in the present study, for which a scientific assessment had not been done previously. The classified-archived-observed river discharge data are obtained from Central Water Commission (CWC) and are applied in an analytical filter to assess the baseflow index (BFI) at all exiting CWC hydro-meteorological sites in the Ramganga river basin. The average values of BFIs for the CWC sites vary between 27% and 38%. The results are found to be consistent and showed significance with the hydrological characteristics of the basin. The results have also been discussed to account for various possible anthropogenic effects, which are assessed as having no significant impact.","PeriodicalId":51911,"journal":{"name":"Journal of Applied Water Engineering and Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49219046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is neither sufficient information on the wash-off coefficients for other types of pollutant nor a good mathematical interpretation that accounts for the effects of surface features on wash-off processes. This study assesses the standard exponential wash-off function using experimental data on the wash-off of various types of pollutant. In-situ wash-off experiments using simulated rainfalls were conducted in typical urban areas with various landuse. Experimental data from the literature were also analysed to support the examination. Mass balance requirement was always applied as a criterion in the experimental data analysis and wash-off model examination. The experimental results indicate that wash-off processes of organic pollutants (BOD5), nitrate (NO3), total oil and grease (TOG), total petroleum hydrocarbon (TPH) and coliform stochastically comply with the standard exponential function. Highlights In-situ wash-off experiments were conducted for BOD5, NO3, TOG, TPH, coliforms and TSS. Wash-off coefficients of BOD5, NO3, TOG, TPH, coliforms and TSS are identified stochastically. Mass balance requirement is introduced to examine the mathematical interpretations of wash-off models. An improved exponential wash-off function with more input parameters is suggested.","PeriodicalId":51911,"journal":{"name":"Journal of Applied Water Engineering and Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42856378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analyses of extreme events were identified by applying the SPI drought index for multiple-time scales of 1-, 3-, 6-month, for meteorological stations located in the Ceyhan Basin, Turkey. While the homogeneity of the data was analyzed with the Wallis-Moore method, trend analysis was performed with the Mann-Kendall test. In addition, the determination of the change-point year was performed with the Standard Normal Homogeneity Test (SNHT) and Buishand’s Range Test.
