Étude de la Performance du Dispositif de Traitement des Eaux UsÉes par Boues ActivÉes de la ville d’Al- Hoceima, Maroc

Morocco has taken over the desire to ensure sustainable development and to promote the treatment of domestic and industrial wastewater. In this context, several sewage treatment plants were created, in order to protect the environment from direct discharges of wastewater, and to hope for the reuse of treated wastewater. The use of Activated sludge process in treating the wastewater has been the solution to many problems. In order to evaluate the performance of wastewater treatment plant of the city of Al-Hoceima (North of Morocco). We studied the physico-chemical and bacteriological parameters; we carried out a series of measures such as: temperature, pH and conductivity, the biochemical oxygen demand BOD5, the chemical oxygen demands COD, fecal coliforms (FC) and total coliforms (TC). Measurement of the BOD5, COD and TSS yields values give respectively 96%, 95% and 85%. The tests showed that the treated water can be obtained with a quality complying with the agricultural reuse

Groundwater Quality Monitoring in Response to Marine Intrusion: A Case Study in Northern Morocco

Water stress, resulting from a demand for water exceeding the available quantity, is a major global challenge. Groundwater usage is a commonly adopted strategy to address this situation, but it often leads to marine intrusion, threatening the quality of water in coastal aquifers. This phenomenon typically stems from overexploitation of aquifers, declining water table levels, and rising sea levels due to climate change. Our study aims to monitor the quality of groundwater intended for human consumption and provide a detailed assessment of its current state. We identified several physicochemical parameters, such as temperature, pH, and bicarbonates, with maximum electrical conductivity values reaching 2810 µs/cm, a total hardness of 21 meq/L, sulfate levels of 689 mg/L, and chloride levels of 628 mg/L, from six boreholes and one well located along the coastal area of the Al Hoceima region. These samples were also subjected to Principal component analysis (PCA) of the chemical parameters, revealing two factors that represent approximately 62.15% of the total variance in the groundwater quality dataset. Simulation results indicate signs of seawater intrusion in several areas, particularly near the coast, emphasizing the urgency of protecting groundwater resources and developing sustainable management strategies to ensure a safe and reliable supply of drinking water in the region

Green Insulation Revolution: A Bibliometric Analysis of Cannabis-Based Composite Materials in Building Construction

Powdered activated carbon was used in different studies for evaluation in micropollutants removal. In this study, powdered activated carbon was tested to evaluate its removal efficiency for about 46 micropollutants. A total of 33 compounds were found in raw wastewater.

Electrocoagulation as a Possible Treatment for Wastewater Contaminated with Microplastics - A Review

Microplastics (MPs) have arisen as an omnipresent pollutant that damages the aquatic ecosystem, raising serious concerns. It has become a massive challenge since MPs have the ability to biomagnify and thereby harm human health, biodiversity, aquatic species, and the environment. Therefore, innovative technologies are needed to efficiently remove MPs. Membrane technologies can be quite effective in the removal of MPs. Furthermore, hybrid membrane techniques such as advanced oxidation processes (AOPs), membrane fouling, electrochemical processes, and adsorption processes can be used to improve efficiency. Electrocoagulation is considered an effective wastewater treatment technique for MPs removal, with the advantages of low cost, independence of chemicals, and ease of operation. The main aim of this work is to demonstrate the potential of electrocoagulation to remove MPs from wastewater and provide an overview of the sources and toxicity of MPs found in wastewater. This study also evaluates various physical, chemical, and biological treatment methods for removing MPs from wastewater

Comparative assessment of groundwater quality challenges confronting Mediterranean coastal aquifers: A synoptic review

Coastal aquifers, essential for agriculture, domestic, and industrial water supply, face significant sustainability challenges, particularly in Mediterranean regions, due to the adverse effects of human activities, climatic threats, and natural geological conditions causing salinization. This paper synthesizes findings from studies on three Mediterranean coastal aquifers— the Pleistocene aquifer in the Gaza Strip, the karstic aquifer in Bokkoya, and the MioPlio-Quaternary aquifer in Djeffara of Medenine—highlighting the escalating deterioration due to over-exploitation and arid conditions. It compares the methodologies used in these studies, such as statistical analysis, geostatistical modeling, and groundwater quality indices, to assess groundwater quality and address salinization challenges. This review aims to identify methodological limitations and propose strategies to fill research gaps, particularly in combating seawater intrusion, to enhance the sustainable management of these critical water resources

Impact Des Facteurs De Pollution Sur La Qualite Des Eaux De La Zone Aval De La Vallee De L’oued Nekor (Al-Hoceima, Maroc)

Water is a precious and essential natural resource for multiple uses. Its use for food or hygiene requires excellent physicochemical and microbiological quality. To assess the quality of well water for human consumption in the Al Hoceima region which is located in North of Morocco, a physico-chemical and bacteriological control was carried out on the basis of 10 water samples from wells in this area. The analyzes were performed on these samples by measuring the following physic-chemical parameters: temperature, pH, electric conductivity (EC), chloride (Cl -),dissolved oxygen, nitrate (NO3 -), and possibly seeking unwanted bacteria (total bacteria, total coliforms, fecal coliforms, fecal streptococci). The samples were analyzed systematically to measure all the physicochemical indicators of pollution. Correlation between pollution parameters were conducted to give a reponse element on the main causes pollution. The results performed analysis, revealed a pollution of an agricultural origin. This is confirmed by the maximum levels of chlorides, which exceed 2640 mg/l, thereby explaining the high conductivity levels (4800μs/cm). In addition 14% of analyzed wells have nitre levels 50mg/l nitrate pollution a not alarming. However, if a pollution of agricultural origin is mentioned, the lithological contribution can not be neglected on the results obtained
