The high nutrient concentration in domestic wastewater effluent can endanger the aquatic life via eutrophication. Thus, research have been carried out to prevent harm life. In regard biofilm reactors successful by far with few limitations. Bio-carrier fabrication of desired shape is one Recently, invention additive manufacturing (AM) object made it feasible fabricate shape. this study manufactured bio‒carrier (AMB) was printed using AM technique, surface area volume ratio as well density...

The Gaza coastal aquifer (GCA) is the only source of water for about two million citizens living in Strip, Palestine. groundwater quality GCA has deteriorated rapidly due to many factors. most crucial factor excess pumping high population density. objective this article was evaluate influence on GCA’s salinity using 10-year predicted future scenarios based artificial neural networks (ANNs). ANN-based model generated predict three that were designed different rates. results showed when rate...

Response surface methodology was used to optimize the Fenton treatment of amoxicillin and cloxacillin antibiotic aqueous solution. Under optimum operating conditions (hydrogen peroxide (H2O2)/chemical oxygen demand (COD) molar ratio 2, H2O2/Fe2+ 76, reaction time 90 min at pH 3), 78.98, 72.96, 81.18% removal COD, total organic carbon, ammonia–nitrogen, respectively were achieved. Experimental efficiency model prediction in close agreement (<0.4% error). Fourier transform infrared spectra...

The study examined the effectiveness of modified photo-Fenton (UV-vis/ferrioxalate/H2O2) process in treatment an antibiotic aqueous solution. optimum operating conditions for a 300 mg/L solution (150 amoxicillin and 150 cloxacillin) were obtained by using central composite design response surface methodology. Under (H2O2/chemical oxygen demand (COD) molar ratio 2.75, H2O2/Fe3+ 75, H2O2/C2H2O4 37.5, reaction time 90 min pH 3), 78.37, 45.94, 52.30% removal COD, NH3–N, TOC, respectively,...

This study examined the degradation of pesticide aqueous solution containing chlorpyrifos, cypermethrin and chlorothalonil by FeGAC/H2O2 process. Under operating conditions (FeGAC 5 g/L, H2O2 concentration 100 mg/L pH 3), chemical oxygen demand (COD) total organic carbon removal were 96.2 79.2%, respectively, biodegradability (BOD5/COD ratio) increased from 0 to 0.40 after 60 min reaction. Complete pesticides active ingredients occurred in 1 min. Kinetic models such as pseudo-first-order,...
