Abstract

Soil pollution is one of the concern issues in the Asia region. Soil acts as a shelter for underground microorganisms and provides nutrients for plants. Most of the organic contaminants are sourced from agriculture and industrial areas. Organic contaminants which are volatilized and immiscible lead to air and water pollution. Electrokinetic remediation is a technology that has been developed for soil remediation since a few decades ago. It is not fully developed and is still under investigation. Electrokinetic remediation is being applied to improve the removal efficiency of organic contaminants which exist in low hydraulic conductivity of soil or fine-grained soil.  Generally, a low direct current, 1DCV/cm is applied. Facilitating agents including surfactant and co-solvent combined with electrokinetic remediation eliminated more organic contaminants compared with electrokinetic remediation alone. Electrokinetic remediation with the addition of bioremediation or phytoremediation process manipulates the transportation of organic contaminants in soil to increase the efficiency of remediation technologies. Electrokinetic remediation is recommended due to its flexibility, cost-effectiveness, and safety. One of the drawbacks is low effectiveness in removing non-polar organic pollutants due to weak desorption capacity and poor solubility in water. Co-solvents and surfactants can be introduced as alternatives to enhancing the solubility of non-polar pollutants and reducing surface tension, which improves their mobility within the soil matrix. These facilitating agents help improve the overall effectiveness of electrokinetic remediation, particularly for challenging contaminants.

Abstract

In engineering education, experiential learning is essential as it allowed students to connect theoretical knowledge with real-world applications. This study explored the impact of industrial visits, a form of experiential learning, on engineering students’ comprehension, critical thinking, and overall educational experience. We employed a mixed-methods approach, integrating questionnaire surveys, reflective writing exercises, and qualitative analyses to assess the learning outcomes and pedagogical implications of these site visits. Our findings demonstrated that industrial visits significantly enhanced students’ understanding of engineering concepts by providing real-world context to theoretical knowledge. Through reflective exercises, students integrated their field trip experiences with classroom learning, fostering critical thinking abilities and a deeper comprehension of the subject matter. This study underscored the importance of curriculum integration. To nurture students as adept problem solvers and critical thinkers in both academic and practical engineering fields, fostering dynamic interactions between theoretical instruction and practical experiences was crucial. Our study encouraged further exploration of how experiential learning could enrich the educational journey, equipping students to tackle complex challenges in our ever-evolving environment as engineering education advanced.

Abstract

This study aimed to determine the efficiency of media pollutant removal from municipal wastewater with high concentrations of ammonia and phosphorus in constructed wetlands  (CWs). The study utilized secondary data from previous studies that were published in credible sources. The removal efficiencies of the five media used in the constructed wetland, namely, peat-cattails, cattails, peat, Viteveria zizanioides, and Phragmite karka, were compared. The results showed that CWs with Viteveria zizaniode exhibited the best performance on average, removing 84% nitrogen and 86% phosphorus. Peat was also effective in attenuating pH. Humic and fulvic acids in peat moss can be released quickly in an aqueous environment under alkaline conditions, effectively lowering the pH value. The combination of Viteveria zizaniode and peat significantly improved pollutant removal efficiency in municipal wastewater with high concentrations of ammonia and phosphorus.

Abstract

While environmental engineering helps to solve major world challenges, it still struggles with diversity, equity and inclusion (DEI). This study seeks to understand the current progress of DEI in environmental engineering education at the university level and for professionals. It analyzes studies related to DEI to discover difficulties that hinder its integration and considers proposed solutions for promoting an inclusive environment. Some main obstacles are the low number of minorities, insufficient DEI information in courses and opposition to reform within institutions. Various promising ways such as making changes to the curriculum, inclusive teaching, student mentorship schemes, instructor development and community involvement are covered. Even so, these different approaches often miss proper support and coordination which reduces their usefulness over time. The review points out flaws in how assessment is done and suggests incorporating DEI concepts throughout education policies, teaching activities and professional life. In the end, it recommends ways that teachers, schools and policy groups can promote DEI by staying committed and joining forces.

Abstract

Clean water awareness through STEM (Science, Technology, Engineering, and Mathematics) activities has become increasingly relevant, especially in rural areas where issues like water pollution and limited access to clean water persist. This paper described an outreach program with the aim of boosting both STEM understanding and health awareness among primary school students in a rural Malaysian community. The sessions were conducted hands-on, involving simple experiments and water filtration demonstrations using readily available materials. These activities highlighted experiential and inclusive learning, aligning with the goals outlined in the Malaysia Education Blueprint 2013–2025. During the program, students explored the science behind water contamination and its health impacts, followed by building their basic water filters. Students responded well during quizzes and interactive tasks, which helped track their learning progress. Notably, their awareness of waterborne diseases and confidence in applying basic filtration methods increased significantly from 15% before the program to full participation and understanding afterwards. Besides gaining knowledge, the activities seemed to shift their attitudes. Many students started asking questions about their household water sources, showing a level of curiosity that was not there before. This kind of learning rooted in real-life context demonstrated that STEM outreach does teach science as well as allows young learners to care about their environment and health. The model used in this program has strong potential to be adapted for other communities where resources may be limited but the need for awareness is in need.

Abstract

Heavy metal (loids) in wastewater persists as a contagious and non-biodegradable environmental pollutant. With the ever rising of nanotechnologies in various field, there is a mass flux of heavy metal (loid)s being transmitted in many water sediments includes wastewater and rivers in which difficult to eliminate through conventional treatment processes. The introduction and development of nanomaterials have been increasingly utilized. Their high absorption capacity and unique properties in eliminating heavy metal pollutants and other nano pollutants have been extensively used in the remediation of inorganic pollutants. This review study illustrates the different types of nanomaterials that are utilized in various treatment process such as nano zero-valent iron (nZVI), carbon nanotubes and titanium dioxide nanoparticles (TiO2NPs). The mechanism of each nanomaterial and also its advantages and disadvantages are being portrayed. The identified factors affecting their efficiency in eliminating heavy metal and other inorganic pollutants are briefly described.
