The study involved 4-year-old olive trees irrigated according to the water requirement estimated by both the SIM model and the FAO56 method. The results showed that neither agronomic and physiological parameters nor leaves were affected by irrigation with TWW. However, the soil reacted differently as its alkalinity but witnessed a decrease in the fresh water (FW) treatments. The soil solution electrical conductivity was generally higher for TWW than FW. The savings on water and fertilizer costs generated by the TWW and TWW + SIM treatments are 570€ and 585€/ha, respectively, and the adoption of the two innovations generates additional net benefits equal to 45,000€, while to the nozzle with TWW alone, additional net benefits were observed that is 42,000€. A minimum increase in return of only 0.6% is needed to cover investment costs over the 30-year life of the project and the investment could be profitable even with a decrease in return of 48%.","PeriodicalId":34727,"journal":{"name":"Water Reuse","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141922310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed significant reductions (p < 0.05) in heavy metal (manganese, zinc, cadmium, magnesium, chromium, and iron) concentrations, with some showing compliance to Ghana's Environmental Protection Agency and the United Kingdom National Environment Regulation recommended discharge limits. Heavy metal concentrations in effluent samples ranged from as low as 0.00 ± 0.15–0.23 ± 0.06 mg/L. Furthermore, there were significant reductions in Escherichia coli and Salmonella typhi (p < 0.05), which also showed compliance to Ghana's Environmental Protection Agency effluent discharge standards. The effluents from the system at HRT 3 days showed high removal efficiency ranges of 82–90% of bacteria.

In this study, a zero-discharge RO system was adopted to treat the ultrafiltration permeate from a steel plant with the combined multi-wavelength UV-LED/chlorine process, focusing on organic structure modification and membrane fouling control. The results showed that the UV-LED/chlorine process could not only efficiently remove the dissolved organic carbon and the total nitrogen of the RO influent but also alter the organic substances from large molecules to small ones. In addition, the longer wavelength of a 295 nm UV-LED/chlorine process exhibited a greater RO permeate flux of 158 LMH, as compared to the shorter wavelength of 255 nm with the flux of 152 LMH. Moreover, compared to the single-wavelength, the dual-wavelength UV-LED/chlorine process played a more significant role in RO filtration performance, which induced a looser and thinner foulant structure, resulting in an 8% larger permeate flux and recovery at 275 + 295 nm than at 295 nm. This study demonstrated that the combined UV-LED/chlorine process could effectively alleviate RO membrane fouling.

After 120 min of incubation, the adsorbent demonstrated a 27.28 mg g−1 of php adsorption capacity at a pH of 4 with 0.5 g L−1 of adsorbent dosage. The adsorption efficacy and mechanism were defined using isotherm and kinetic models. The study investigated the impact of different factors, including initial concentration, reuse of FeAcC, recirculation flow rate, and hydraulic retention time (HRT), on the efficiency of php removal. The optimum removal efficiency was observed at approximately 95% after 20 min of operation at 1.5 L min−1 recirculation flow rate (batch FBR) and 70 min of HRT (continuous FBR) under a 400 mg h−1 ozonation rate. Experimental parameters were optimized using response surface methodology with central composite design to improve php removal.
