This study aimed to assess the water quality of the Nile River at the Damietta Branch. Water samples were collected from the Damietta branch, the physico-chemical parameters and some heavy metals were analyzed which includes; temperature, pH, Turbidity, EC, TDS, alkalinity, total hardness, Ca +2 and Mg +2 hardness, chlorides, sulfates, and aluminum, ammonia, nitrite, nitrate, iron, manganese, and silica. The results indicated that, the turbidity value was 7.81 NTU, while temperature, pH, EC, and TDS were 23ºC, 8.03, 403.75 µmohs/cm, and 266.25 mg/l, respectively. The concentrations of alkalinity, total hardness, Ca +2 and Mg +2 hardness were 142, 131.5, 82.5, and 49 mg/l, respectively. While chlorides, sulfates, and aluminum concentrations were 27, 34.25, and 0.063 mg/l, respectively; ammonia, nitrite, and nitrate concentrations were 0.13, 0.083, and 0.59 mg/l, respectively. Iron, manganese, and silica concentrations were 0.058, 0.05, and 1.3 mg/l, respectively. Results from Water Quality Index (WQI) reveal that Nile River waters were generally categorized as poor quality or unfit for drinking purposes leading to presence of high pollution in the river. Water sample with Pollution Index observed that heavy metals concentrations had moderately affected except Cu +2 , Co +2 , and Zn +2 were not detected in raw Nile River water. Perhaps, new recent trends of treatment have to be designed so as to decrease the pollution load of the rivers..","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74950569","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}

Current study for Nile water treatment revealed that the optimum dose was 10 mg/L and 4.6 mg/L for ozone and chlorine, respectively. The concentration of ozone and chlorine were under permissible limits according to the Egyptian standards for drinking water. The current work was shown to monitor TBC, TCs, FCs, and non-FCs by removal percentage reaching to 99.87, 99.97, 99.96, and 99.02% for each, respectively, for chlorine. While with ozone the removal percentage reaching to 99.9, 99.95, 99.93, and 98.92%, respectively. Microbiological examinations include: Total plate count, total coliform, total algal count, and microscopic examination. The ozone Algal counting analysis revealed that, total algae, green algae, blue- green algae, and diatoms with removal efficiencies of 91.07, 90.24, 100, and 88.24%, respectively, chlorine counting analysis show removal efficiencies of 94.42, 95.08, 100, and 91.62%, respectively. It’s concluded that using ozone is one of the future ways to meet the environmental water standards and supply the water requirements of the growing population.","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89005356","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, these areas are the most vulnerable to climate change. In this study, we look into climate change consequences and the potential regional adaptation methods to them, with an emphasis on coastal risks. We evaluated their efficacy in terms of both the coastal management methods for which they were designed as well as the climate change in the long term. Because the assessment is not reliant on the local environment only, it is applicable to most coastal locations. We undertook a literature analysis to identify measures that may be applied to the coastal area of Damietta. The EMA (Egyptian Meteorological Authority), the Egyptian Environmental Affairs Agency (EEAA), the Climate Change Performance Index (CCPI), and the Intergovernmental Panel on Climate Change's (IPCC) classification of adaptation measures based on institutional characteristics, socioeconomic characteristics, or physical-environmental characteristics are used to categorize these metrics in these two integrated methodologies. Parallel to this, a number of standards were developed to evaluate the measure's present and potential efficacy, regardless of the context. At last, this strategy enabled objective and straightforward comparisons between measurements by assessing the adaptation strategies according to these standards and predictions of the challenges we will face in the future. The study proposed several extension strategies to raise awareness about the expected consequences of climate change.","PeriodicalId":21655,"journal":{"name":"Scientific Journal for Damietta Faculty of Science","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87816388","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}
