“…The comparison of water quality physico-chemical parameters and major dissolved ions in this study and those of previous studies in Bahr El-Baqar drain, Lake Manzala and the River Nile are reported in Table 3. It is concluded that the average value of pH (7.48) in this study is higher than (6.6-7.35) previously reported in the water of Bahr El-Bagar and Kitchener drains [12,18,20], while it is lower than those of [1,5,7,11,16,25,[27][28][29][30][31]33] (Table 3). The average TDS (1685.8 mg/L) in the drain water is higher than (2.8-1485 mg/L) repored before [5,12,[29][30]33], however, it is below those of [1,16,[27][28] (Table 3).…”

“…Bahr El-Baqar drain is one of the most polluted drains in Egypt [6]. The drain is located in the eastern part of the Nile Delta with a length of about 170 Km starting from north Cairo, where Belbeis (east) and Qalubiya (west) secondary drains meet together near Zagazig, Sharqiya Governate and ending into Lake Manzala south of Port Said city [1,11] (Fig. 1).…”

This study assessed the seasonal and spatial variation of the water quality physicochemical parameters, major dissolved ions, and the bacteriological indicators of sewage pollution in Bahr El-Baqar drain, Eastern Nile Delta, Egypt, in the summer and winter seasons of 2018. Results showed that the drain water contained higher values of the physicochemical parameters: pH, Total dissolved salts (TDS), Electrical conductivity (EC), Dissolved oxygen (DO), Biological oxygen demand (BOD), and Chemical oxygen demand (COD), which are typical for domestic and industrial wastewater. The concentrations of dissolved salts (mg/L) in the drain water followed the decreasing order: Cl − (743.5) > NO 3 − (30.26) > NH 4 + (18.22) > PO 4 3-(2.63). Additionally, the bacteriological indicators; Total Viable Bacteria (TVC), and Total Coliform (TC) groups in the investigated drain water samples. Results of TVC, which counted by standard plate method (SPC) and the TC showed high seasonal levels of sewage pollution in the water of the Bahr El-Baqar drain, particularly in the summer samples. The TVC ranged from 3.8 × 10 4 (winter) to 6.4 × 10 5 CFU/ml (summer), which highly exceeds (≤ 1000 CFU/ml) the recommended limit set by Egyptian Law No. 48/1982 for protection of the River Nile and waterways from pollution. Similarly, the TC ranged from 1.3 × 10 6 (winter) to 9.3 ×10 7 CFU/ml (summer), which highly exceeds the World Health Organization (WHO) safe limit (≤1000 CFU/100 ml) for wastewater use in irrigation. This study provides the current pollution status of Bahr El-Baqar drain to find sustainable solutions for the national water vulnerability crisis.

“…Manzala Lake constructed wetland is intended to treat 25,000 m 3 of wastewater per day from Bahr El-Baqr, before it reaches Lake Manzala. In the constructed wetland, a ve-stage treatment will be taken into account beginning with a pumping station lifting water from the Bahr El-Baqr drain that will be kept in the sedimentation basin for two days [15]. The study was carried out between May 2018 and June 2019.…”

In areas with limited water resources, the reuse of treated drainage water for non-potable purposes is increasingly recognised as a valuable and sustainable water resource. Numerous pathogenic bacteria found in drainage water have a detrimental impact on public health. The emergence of antibiotic-resistant bacteria and the current worldwide delay in the production of new antibiotics may make the issue of this microbial water pollution even more challenging. This challenge aided the resumption of phage treatment to address this alarming issue. In this study, strains of Escherichia coli and Pseudomonas aeruginosa and their phages were isolated from drainage and surface water from Bahr El-Baqar and El-Manzala Lake in Damietta governorate, Egypt. Bacterial strains were identified by microscopical and biochemical examinations which were confirmed by 16S rDNA gene sequencing. The susceptibility of these bacteria to several antibiotics revealed that most of the isolates had multiple antibiotic resistances (MAR). The calculated MAR index values (> 0.25) categorized study sites as potentially hazardous to health. Lytic bacteriophages against these multidrug resistant strains of E. coli and P. aeruginosa were isolated and characterized. The isolated phages were found to be pH and heat stable and were all members of the Caudovirales order as recognized by electron microscope. They infect 88.9% of E. coli strains and 100% of P. aeruginosa strains examined. Under laboratory conditions, the use of a phage cocktail resulted in a considerable reduction in bacterial growth. The removal efficiency (%) for E. coli and P. aeruginosa colonies increased with time and maximized at 24 hr revealing nearly 100% reduction after incubation with the phage mixture. The study candidates new phages for detecting and control other bacterial pathogens of public health concern to limit water pollution and maintain adequate hygiene.

A green technique that emerged as a promise in the degradation of numerous organic contaminants is photocatalysis. The aim of this study concerns photocatalytic degradation of organic using titanium dioxide nano particles (TiO2 NPs) which syntheses from ilmenite by different leaching methods using different ingredients such as HCl, HNO3 and Aqua Regia. The affecting factors such as rate of addition, reaction time, ilmenite grain size, acid to ilmenite ratio and reaction temperature were conducted. Comprehensive physicochemical characterization of Ilmenite and TiO2 NPs were conducted using different analytical techniques such as XRD, XRF, SEM, TEM and FTIR. Photocatalytic degradation of organics is confirmed by studies of affecting factors on the effectiveness of TiO2 NPs such as dose, agitation forces, light intensity, initial concentration, pH, time, and temperature. The removal percentages of TSS, COD, BOD and TN of organics were explored. From the results the maximum removal percentage of TSS were 97.3 and 96.9% before and after secondary treatment conducted using ferric chloride (FC). The maximum removal percentage of TKN, BOD, and COD before secondary treatment were conducted using mixture of TiO2 NPs, FC, and chitosan, which reached 44.2, 44 and 46.3%, respectively. The maximum removal percentage of TKN, BOD, and COD after secondary treatment were conducted using mixture of TiO2 NPs, FC, and chitosan, which reached 94.9, 99.7 and 99.6%, respectively. Overall, the results derived from this investigation suggest that the TiO2 NPs/UV holds significant advanced treatment of sewage water, making it a viable choice for water reuse applications.
