Opis:: Oued Nfifikh is among the least studied Moroccan rivers. Thus, the primary aim of this study was to shed light on the quality of this undervalued stream. Its downstream part is affected by one of the most crucial environmental issues. It receives the discharges of wastewater evacuated precariously without prior treatment, which might lead to the degradation of the overall ecological status of this fluvial hydrosystem. This research work aimed to study the physicochemical water quality downstream the river Nfifikh through a monthly monitoring of the physicochemical parameters’ indicator of pollution, from August 2018 to July 2019. The results obtained show that the stream is exposed to high pollution which is mainly organic. Consequently, the wastewater represents a major cause of water quality degradation of this receiving environment: ecological and health impacts are therefore to be expected.

Opis:: The surface treatment industry generates effluents with a high load of highly toxic chemicals which must be treated under increasingly stringent regulation. The aim of this study was to treat the effluents of surface treatment unit of an aeronautical industry by the electrocoagulation process using aluminium electrodes. This process is used to study the performance to remove colloidal load, significant amount of oxidizable material and high levels of various metal elements (Cr, Fe, Zn, Cu and Al) from these effluents, under optimum conditions of pH 7, 8.6A of current intensity and 60 min of application. The electrocoagulation process was found to be effective in reducing turbidity (97.12%), COD (97.5%), SS (97.84%) and conductivity (96.82%), hexavalent chromium (99.99%), Zn (96.82%), Cu (94.3%), Iron (99.9%), Al (91.96%). The treated effluent conformed to the Moroccan standards of surface treatment discharge.

Opis:: The sewage sludge recycling as an agricultural land resource has received a great deal of attention worldwide. This practice has highly increased because of ever-increasing municipal wastewater production and the awareness of its fertilizing potential as amendment resources. However, there is a concern about land spreading linked mainly to health associated risks due to the presence of diverse pollutants. Thus, sewage spreading management is a key factor the guarantees benefits and avoids risks. The present work aimed to investigate the benefits and risks of sewage sludge (SS) application on agricultural land. To this end, physicochemical main parameters and bacteriological indicators, fecal coliform (FC) and fecal streptococcus (FS), of the sewage sludge generated form WWTP of Skhirat, Morocco, were performed during the period 2018–2019. The obtained results of physicochemical parameters reveal high concentration of organic matter in SS, which reach 96.3 mg/l, and in nutrients. Indeed, total Kjeldahl nitrogen TKN reaches a maximum of 3791 mg/l, potassium K+ reaches 58.71 mg/l. In addition, the average content of FC and FS are around 5.40 CFU/ml and 5.85 CFU/ml, respectively, whereas total phosphorus reaches 508.25 mg/l. In addition, concentrations of micronutrients such as Cl-, SO42-, Ca2+, Mg2+, and Na+ were high, which is interesting and could benefit for both soils and plant. Furthermore, this sewage sludge contains high concentration of heavy metals, mainly zinc and copper which could limit reuse in land spreading. The obtained results were compared to the applied standards and directives established within the framework of the agricultural spreading.
