“…(COD) concentration is 35 mg/L. The previous proposed reclaimed water standards were used by Ahmed Rashed (2016) [29] within the Lake Manzala engineered wetland project to cultivate tomato, eggplant, and chilli pepper on rice bale media placed on an extremely saline sodic soil in the Lake Manzala area using treated drainage water. Irrigation water quality parameters were (EC) 5.45 dS/m -1 , (pH) 7.95, dissolved oxygen (DO) 5.3 mg/L, (BOD) 6.17 mg/L, (TN) 5.22 mg/L, (TP) 1.82 mg/L, and Facle coliform (FC) 230 FCU/100 mL the yields produced per hectare were 30.0 ton for Tomato, 23.3 ton for Eggplant and 6.67 ton for Chilli Pepper.…”

The subjects of wastewater treatment and the reuse of reclaimed water are of excessive significance, especially in the regions where the lack of conventional resources is an essential problem as the situation in Egypt. This paper examines the present status for the reuse of reclaimed water in Egypt and future national water plan for reclaimed water reuse. In addition, to review the reclaimed water reuse standards for indirect irrigation in Egypt, organizations (World Health Organization (WHO) and United States Environmental Protection Agency (USEPA)) and countries (Spain, Italy and Cyprus) that have been modified reclaimed water reuse standards. In addition, the study proposing standards for reclaimed water reuse in irrigation purposes aimed to maximize environmental outcomes. The proposed standards were in terms of salinity, nutrients, turbidity, total suspended solids (TSS), pathogens, trace elements, biochemical oxygen demand (BOD) and chemical oxygen demand (COD). The proposed turbidity in (NTU) for cooking vegetables up to 10, (TSS) for cooking vegetables ≤10 mg/L and for cooking crops for human consumption ≤35 mg/L. (BOD) concentration for cooking crops for human consumption and for cooking vegetables were ≤35 and ≤15 mg/L respectively. (COD) concentration ≤ 35 mg/L. The proposed standards concentrations for Aluminium (Al), Cobalt (Co), Beryllium (Be), Lithium (Li) and Vanadium (V) that not detected in the Egyptian local Decree 92/2013 were added as 0.5, 0.05, 0.02, 0.5 and 0.05 mg/L respectively. Egyptian local Decree put high levels of Molybdenum (Mb) (0.07 mg/L) and the study proposes a concentration of 0.01 mg/L. Finally, (USEPA) standards for pathogens were proposed in this study. This study is expected to encourage reclaimed water reuse in Egypt in irrigation practices.

“…The United States Geological Survey (USGS) defines brackish waters as having a dissolved-solids concentration between 1000 and 10,000 mg/L, which is greater than that of freshwater (> 1000 mg/L), but less than that of seawater (35,000 mg/L) [ 71 ]. In the semi-arid and arid regions of the United States and other countries, brackish water use has been largely restricted to relatively salt tolerant crops including cotton, sugar beets, barley, wheat, safflower, sorghum, soybeans and tomatoes [ 29 , 32 , 57 , 58 , 64 ]. The effects of salt stress on plants when irrigated with brackish water are well described in the literature [ 27 , 70 ], and multiple mitigation strategies are being explored to enable these water sources to be suitable for irrigation purposes [ 32 , 57 , 58 , 64 ].…”

Nontraditional irrigation water sources (e.g., recycled water, brackish water) may harbor human pathogens, including Vibrio spp., that could be present in a viable-but-nonculturable (VBNC) state, stymieing current culture-based detection methods. To overcome this challenge, we coupled 5-bromo-2′-deoxyuridine (BrdU) labeling, enrichment techniques, and 16S rRNA sequencing to identify metabolically-active Vibrio spp. in nontraditional irrigation water (recycled water, pond water, non-tidal freshwater, and tidal brackish water). Our coupled BrdU-labeling and sequencing approach revealed the presence of metabolically-active Vibrio spp. at all sampling sites. Whereas, the culture-based method only detected vibrios at three of the four sites. We observed the presence of V. cholerae, V. vulnificus, and V. parahaemolyticus using both methods, while V. aesturianus and V. shilonii were detected only through our labeling/sequencing approach. Multiple other pathogens of concern to human health were also identified through our labeling/sequencing approach including P. shigelloides, B. cereus and E. cloacae. Most importantly, 16S rRNA sequencing of BrdU-labeled samples resulted in Vibrio spp. detection even when our culture-based methods resulted in negative detection. This suggests that our novel approach can effectively detect metabolically-active Vibrio spp. that may have been present in a VBNC state, refining our understanding of the prevalence of vibrios in nontraditional irrigation waters.

“…To this goal, 2 different approaches were applied for the ICW and for the CFL. For the first technology, on the basis of the encouraging results obtained by the National Water Research Council of Egypt in previous pilot‐scale tests of DCW treatment by means of constructed wetlands (Rashed 2016; Rashed and El Gammal 2018), an actual tertiary drainage canal—the Edfina drainage canal (DC) in the western Nile Delta—was upgraded to an ICW and the resulting water treatment performances were monitored for 18 mo. The model‐based design of the ICW used for the LCA and CBA was thus performed on the basis of the results obtained in the experimental full‐scale ICW.…”
