“…However, it has been reported that algae may consume large amounts of chlorine and thus reduce the free chlorine available to control bacteria if they continue after treatment (Shen et al, 2011;Mohamed et al, 2020). Moreover, it has been reported that an overdose of oxidizing substances should be avoided because it can cause damage to algal cells and release harmful toxins or offensive taste and odor-related compounds or water-color in case of an overdose (Heng et al, 2008;Shen et al, 2011;Yanxia Zhao et al, 2021).…”

In Egypt, the Nile River is inhabited by various phytoplankton species through the whole period of examination. In all months, diatoms dominated other groups by numbers, Diatoms numbers of Nile water ranged between 1450 and 11880 Unit/ml; this was followed by green algae which ranged between 700 and 1220 Unit/ml, while the lowest number was observed for blue-green algae which ranged between 160 and 703 Unit/ml. Treatment of Nile water using two chemical coagulants, namely, aluminum sulfate (Al2(SO4)3.16H2O) and aluminum oxide (Al2O3) removed algae by about 85% and 90%, respectively, on the addition of a permanganate (KMnO4) dose between 0.4 and 1.0 mg/l to the applied coagulant dose removed algae by about 92.5% and 97.2%, respectively, as well as reduced the chlorine dose and the residual aluminum concentration in the treated water. Also, the addition of a Copper (II) sulfate (CuSO4 instead of permanganate) dose between 0.25 and 1.0 mg/l to the applied coagulant dose removed algae by about 93.8% and 98.1%, respectively. Moringa oleifera seeds present a viable alternative natural coagulant, which raises the removal efficiency for the algal groups, and algal removal achieved between 92% and 97% with a dose between 2 and 8 g/l. Algae have been classified and identified through the comparative morphology of algae in identification keys and the Sedgwick-Rafter counting chamber was used to calculate algal numbers.

“…Furthermore, algae cannot be successfully removed by applying chemical coagulation alone due to low specific gravity and their small size The use of a natural coagulant from MOS in place of conventional coagulants such as aluminum salts has been recognized as an effective and efficient technique to remove undesirable chemicals from contaminated water in both residential and industrial water treatment. The seeds of Moringa oleifera can be used to treat water because they contain coagulation-effective protein components (Delelegn et al, 2018;Zhao et al, 2021;Koul et al, 2022).…”

Clean drinking water must be available to stop the spread of numerous watertransmissible diseases. They can create biological poisons, chemical odors and chemical tastes when exposed to certain environmental circumstances (Abd El-Hady, 2014). In terms of water treatment authority, algae are crucial, particularly those from the cyanobacteria family (Lei et al., 2021). Additionally, they hinder several water treatment procedures, reducing the amount of potable water produced. Due to their silicon frustules, diatoms frequently block filters. (Ahmed, 2016; Abouzied, 2021).Algae have few inhabitants and are scattered throughout lakes and rivers, but when nutrients become more plentiful in surface waters, their population is vulnerable to fast growth (Al-Jadabi et al., 2023). This may cause the amount of oxygen in the atmosphere to decline and the turbidity of the water to increase, and the degradation of the aquatic environment, as demonstrated by Shen et al. (2011) and Wang et al. (2013). Stressful environmental situations

“…In recent years, many methods including adsorption, 6,7 membrane separation, 8,9 microbial treatment, 10,11 coagulation, 12 ozone, 13,14 and Fenton treatment, 15,16 as well as photocatalytic degradation [17][18][19] have been proposed for the treatment of dyeing wastewater. However, there are still some disadvantages of high cost, low efficiency, incomplete removal of pollutants, and generated secondary pollution [20][21][22] with the above solutions.…”

Electrolytic active water was prepared by electrolytic treatment of sodium chloride aqueous solution using a self-made device. In order to investigate the properties of electrolytic active water , the pH value, available chlorine contents and decolorization ability on methylene blue solution were tested and compared with that of sodium hypochlorite aqueous solution. Experimental results showed that the electrolytic active water has higher oxidation capacity and decolorization efficiency for methylene blue compared with sodium hypochlorite solution, implying maybe other reactive oxygen species components besides hypochlorite existed in the electrolytic active water. The electrolytic active water was stable under long-term storage, and mechanical force with oxidation activity did not decrease. In addition, the decolorization kinetics of methylene blue in the electrolytic active water was explored, and it was found that, in general, the decolorization reaction of methylene blue in electrolytic active water was consistent with the first-order reaction kinetics model, but when the pH value of electrolytic active water solution was weakly alkaline or neutral, the decolorization reaction of methylene blue was closer to the second-order reaction kinetics model.
