“…We note that the progressive addition of this coagulant to wastewater resulted in a pH decrease from 8.19 to 7.6.at optimum dose 150mg/L. This decrease of pH explained due able of alum in released of H + ions when dissolution in water [25], and can be interpret the decrease in pH result the reaction of natural alkalinity found in water in water with aluminum [24].…”

The goal of this study was to investigate the performance of coagulation-flocculation, and sedimentation tests to reduce contaminant concentrations in domestic wastewater to ecologically acceptable levels. The tests were performed at the (ONEE) laboratory using a jar test apparatus (GPB FLCDidatec, France) for enhancing the primary treatment of domestic wastewater effluent from the wastewater plant of Ain Aouda City, Rabat, Morocco. Aluminum sulphate Al2(SO4)3.18H2O (termed alum) was employed as a coagulant in the study. The impact of coagulant doses and pH at optimum dosage on the process of coagulation was studied and conditions were optimized to obtain the best removal of studied pollutants. The evolution of physico-chemical parameters pre-and post-treatment was monitored to determine the efficacy of the process. The turbidity and total suspended solids (TSS) were the best indicators of the treatment’s efficacy of coagulant concentration (150mg/L) within the pH optimum of 7. Laboratory tests have shown 98.4% of turbidity, and 97% total suspended solids removal at initial concentrations of 121 NTU, 220 mg/L respectively. Also, it has shown good removal efficiency for COD, BOD5 of the order 83%, 77% at initial concentrations of 340 mg/L, 150 mg/L respectively. Following the coagulation tests, the examination of the main parameters studied revealed that the degree of contamination had decreased. This is confirmed that Aluminium sulphate as a coagulant has proven its effectiveness in the treatment of domestic wastewater in this study.

“…Essentially, inadequate dose or overdosing would result in low flocculation results. As a result, determining the optimal dose is significant to reduce cost of dosing, sludge formation, and also, simultaneously achieving the best treatment results [24].…”

“…Simulations can be carried out in both steady state and dynamic mode. For example, Mabrouki J et al 2020 carried out steady-state simulations of a set of urban wastewater fractionations from the Moroccan city and the coefficients acquired were validated in dynamic regime [18,34]. In each regime, it is possible to make calibrations, adjustments, sensitivity analyses and process customization.…”

“…Many studies have focused on the measurement of membrane fouling, using monitoring of fouling resistance during reactor operation, or in parallel [18]. The study authors also often relate the filtration behavior of the sludge to its biochemical composition and in particular to the amount of extracellular polymers present in the flocs and in the surface supernatant [19][20][21][22][23][24].…”

Membrane-based systems (MBR) used in wastewater treatment have many advantages over conventional activated sludge processes. They have proven to be very effective in removing organic and inorganic contaminants as well as biological entities from water. The objective of this work is to propose an optimal operation of the bioreactor after having detailed in the relationships between the nature of the sludge, its conditions is obtaining the performance of the membrane using a simulation software (GPS-X). The effects of organic and hydraulic shock loads on the MBR system were also studied. The GPS-X simulation program was used in this study to simulate the membrane bioreactor setup. The BOD removal system we used was 78%. In addition, the MBR system has a significant capacity due to the hydraulic shock load of the operation and the process efficiency for the MBR installation due to this shock load based on BOD removal was reduced up to 65%. The MBR system has a good ability to handle the organic shock loads of the operation with no significant loss in treatment efficiency. The treatment efficiency of the MBR system, due to organic shock loads based on BOD removal, decreased slightly to 80%, however, it is shown how their properties determine the extent of sludge fouling in the membrane. Based on these results, operational conditions favoring a reduction of fouling are proposed.
