Its recognition as an intangible heritage has led its production to bring benefits in economic terms. However, there are environmental problems indicated by its production, and one of which is the water use. It is common to find information regarding the pollution caused by batik production. However, studies on water footprint of batik could bring insight that batik problem in relation to water doesn’t limit solely to pollution, but also to the huge volume of water consumed during batik production. In this understanding, the WF approach, both consumptive and degradative water use, is important. Although studies on batik WF have been conducted, it is still limited. This paper discusses the challenges faced in exploring batik WF based on field experience. An understanding of batik itself and batik SME characteristics are required because they are closely related to the WF of the process. Finally, this paper explains the conceptual and technical challenges that will be faced during the study of batik WF.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140368611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts were made to study the effect of different physico-chemical parameters of the soil sample on the horizontal spread of phenanthrene. The concentration of the hydrocarbon at different points of time was determined by high-performance liquid chromatographic analysis of soxhlet extract of soil samples drawn from different distances from the point of application of the hydrocarbon. Simultaneously, internal samples were also analysed in order to detect the efficiency of the process of extraction and the extent of degradation during the study period. The ambient temperature of the place of the experiment was in the range of 23.6 to 35.5°C, which is suitable for microbial activities. From the internal experiment, it was found that there was a 36% loss of phenanthrene which indicates degradation during these four months of the experiment. It has been found that most of the Phenanthrene molecules move a distance of 15 cm from the point of application in the first 60 days. As such the most probable rate of horizontal spread became 2.89 × 10-8 m s-1.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140371792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, numerous homes have been built on a big scale.

The concern about the sustainability of expansion is raised by the rapid exploitation of such resources, which also leads to environmental imbalance. Numerous thousands of tonnes of waste are produced as a result of the rapid growth, which creates problems with not only disposing off the waste but also with the availability of landfill spaces in urban areas. This project aims to conduct an experimental analysis of the potential use of bagasse ash, rice husk ash, plastic waste powder, and municipal wastewater sludge as clay substitutes in brickmaking. Testing the efficacy of these materials revealed that the bagasse ash brick with plastic waste powder demonstrated a significant increase in compressive strength and less water absorption when compared to a conventional brick. According to the test results, the average compressive strength of the bagasse ash brick created using plastic waste powder is 9.81 N/mm2 and 9.03 N/mm2, respectively, which is higher than the standard necessary construction brick according to our Indian requirements. These bricks can be utilised as first- and second-class bricks. These bricks can be used in both load-bearing and non-load-bearing structures because the average water absorption, according to specifications, was not more than 20%.

The results showed that the maximum wind speed was 4 m/s at 12:00 noon, while the prevailing wind direction for all sites in Iraq was towards the northwest (NW) and the minimum wind speed was 2 m/s at 00:00 AM. By analysing the monthly wind speed and direction for some selected stations, it was found that the highest value of (SW), i.e., 64% was recorded at Rutba station, and the lowest value of (SW) at Basra station was 45%, where the prevailing direction was found to be towards the north-northwest (NNW). The spatial analysis concluded that the wind movement is directed from the north and northwest, explaining that the wind reverses its direction from the mountainous heights to flat lands due to the roughness of the surface in the northern regions above the stations of Iraq. Spearman’s test was carried out between wind speed and surface roughness, and between carbon dioxide and surface roughness. It was found that the correlation strength is weak, and the relationship is inverse between surface roughness and wind speed. This analysis is considered the best way to choose the best wind power plants.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139860736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic nanoparticles have come to light as a viable arsenic remediation technique, providing a fresh and long-lasting water purification method. This study investigates the use of magnetic nanoparticles to remove arsenic by concentrating on their adsorption mechanism, kinetics, potential for adsorption, recovery, and promising use of this method in the future. Due to the extensive surface area and variable surface chemistry of magnetic nanoparticles, they can effectively adsorb arsenic from water sources. Because their magnetic properties simplify separation and regeneration, they may be used again with little to no efficiency loss. As a result, they reduce trash output by providing an ecologically acceptable alternative to traditional adsorbents. The present study also examines the kinetics and adsorption process of magnetic nanoparticles, emphasising their improved selectivity and capacity for adsorption. Due to these characteristics, the authors were able to successfully remove arsenic from wastewater, resulting in better water quality and decreased health hazards after exposure to arsenic. Additionally, the potential applications of magnetic nanoparticles in removing arsenic have been highlighted. It is envisaged that advances in material science and nanotechnology will create unique magnetic nanoparticles with even better performance. Combining hybrid materials and surface alterations can increase their effectiveness in wastewater treatment settings.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139861476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These adsorbents were characterized via different characterisation FESEM, TEM, XRD and EDX to give high confidence of the prepared surface. The adsorption of Clonazepam drug (CLZ) from aqueous solution on the SA/Bn beads was investigated as a function of different factors, including the initial concentration of CLZ, the weight of SA/Bn beads gel, pH solution, temperature of solution and equilibrium time. Adsorption models of Langmuir and Freundlich isotherms were applied and were found to be well described via the isotherm of Freundlich model. The results showed that among the three types of prepared surfaces SA/Bn beads, SA-Bn1 presented the greatest CLZ adsorption capacity. Thermodynamic parameters were calculated including change free of Gibbs energy (ΔG), change entropy (ΔS), and change enthalpy. The change enthalpy of CLZ drug adsorption was found to be positive for the SA/Bn bead and the reaction of adsorption spontaneous and exothermic. After the adsorption proses the SA/Bn beads can easily be regenerated via water and re-used within four cycles.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139799252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
