“…In Algeria, a comparison study of two free biomass treatment plants (aerated lagoon and activated sludge) concluded that there is an asymmetric distribution of the pH values in both treatment plants. The aerated lagoon reflects an asymmetric distribution towards low pH concentrations, whereas the activated sludge reflects an asymmetric distribution towards high pH concentration values (Bachi et al, 2020). However, it should be noted that the pH values that are too acidic or too basic could affect the biological treatment processes.…”

“…The same is true for Petala et al, (2006), who managed to achieve a turbidity removal percentage of about 45% after sand filtration, while the activated carbon process increased turbidity removal to more than 60%. The study conducted by Bachi et al, (2020) on the performance comparison of two free biomass treatment systems (aerated lagoon, activated sludge), showed that the SS removal rates were highest in the case of the activated sludge system (96.6%-93.4%) and the lowest in the case of aerated lagoon system (39.2%-67%) with an average difference of more than 43%. These results allow concluding that the combination of the investigated treatment system was successful in removing particulate pollution.…”

In order to use the purified wastewater for the irrigation of a golf course in the Taghazout area (Southwestern of Morocco), this study was conducted to evaluate the physicochemical and bacteriological quality of the treated wastewater in the new Aourir plant (Activated Sludge technology). In order to achieve these objectives, three types of water were analyzed: raw water (RW), biologically treated water (BTW) and water treated by ultraviolet radiation (UV-TW). The physicochemical parameters analyzed were Temperature, pH, Electrical Conductivity (EC), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), five-day Biological Oxygen Demand (BOD 5 ), Total Suspended Solids (SS), Nitrate (NO 3 ), and Orthophosphates (PO 4 ). Otherwise, the analyzed biological parameters are Total Coliforms (TC), Fecal Coliforms (FC), Escherichia coli (E. coli), and Fecal Streptococci (FS). The physicochemical parameters showed that temperature is always lower than 30°C, the pH is close to neutrality and a strong fluctuation of the high electrical conductivity (2700 μS/cm) occurs in UV-TW. At all stages of wastewater treatment, COD, BOD 5 , SS, NO 3 and PO 4 were below the limit values recommended by Moroccan standards. The bacteriological results showed a high level of bacterial contamination in RW and BTW, but in UV-TW the loads did not exceed 3 log10. The average loads of TC, FC, E. coli and FC in UV-TW were 2.13, 1.67, 1.77, and 2 (log10 CFU/100ml) respectively. Activated sludge treatment combined with UV has demonstrated sufficient quality to reuse treated water in irrigation; however, the UV treatment requires control to avoid any effect on the microbiological and physicochemical quality of green spaces and groundwater.

“…It is one of the fastest growing food sectors in the world, which almost contributes to 50% of total fish consumption per capita (Poonkodi, 2014). In addition, in 2014, most of the fish for human consumption came from aquaculture, and this trend must continue to satisfy future demands for global food production (FAO, 2016 andBachi et al, 2020). Besides, aquaculture is a lucrative activity offering better employment and foreign exchange prospects for a nation (Ginson et al, 2017).…”

quality parameters are suitable for the breeding of the fish Oreochromis niloticus. However, the transparency, the conductivity and the recorded phosphate results were not compliant with the standard values , which are respectively between 30 -80 cm, 150-450 µS/cm and 0.5 mg/L. The values of the TDS / EC ratios (0.48 -0.78) and the pollution indices (2.00 -2.66) showed a strong mineralization of the water and a high level of organic pollution in all the structures of the farm which indicate a eutrophic state of the water of the dam and the ponds. So this eutrophication phenomenon can lead to long-term stress and mortality of fish if adequate measures are not taken.
