“…The result of optimization from tensile strength of the PES-biopolymer pervaporation membrane (with optimum value of tensile strength of 0.242 kgf/cm 2 with the actual result of 0.245 kgf/cm 2 ) shows that the influence of chitosan alginate coating on PES membrane is quite strong although PES membrane is mechanically strong enough. This is due to alginate and chitosan have good adhesiveness, good film formation, biocompatibility, and easy to modify [2]. Compared to the control group, PES membrane, without chitosan alginate coating which has an average value of tensile strength of 0.2114 kgf/cm 2 , is still found to be lower than the tensile strength of PES membrane of 0.245 kgf/cm 2 with 3.247% alginate and chitosan concentration of 2.909%.…”

“…Before it can be used, the process of separating and purifying bioethanol are essential steps that must be passed because bioethanol as biofuel must have a purity of at least 99.5%. The widely used technology at this stage is conventional distillation [2]. Pervaporation (PV) is a separation process using membranes with different pressure from the driving force.…”

Some outstanding features in the use of pervaporation technology are light, low maintenance, low energy consumption, and eco-friendly. The optimization of membrane mechanical properties is vital to determine the strength of the membrane against the force which comes from outside and is unfortunately destructive, one of which is tensile strength. The purpose of this research is to find out the best combination of alginate and chitosan concentration, which produces polyether sulfone-biopolymer based pervaporation membrane with optimal tensile strength. Several membrane compositions have been prepared and varied in a way to obtain optimal membranes. The modeling and optimization method, which was applied by the researcher is the Response Surface Methodology (RSM). In the Central Composite Design (CCD) design, the low level included for both factors is 2% concentration, and the high level is 4% concentration, with a total of 13 experimental designs. The result of the suggested model is a quadratic model. While on the optimization result, the optimum solution result is from a combination of 3.25% alginate and 2.91% chitosan concentration, which yield tensile strength value of 0.24 kgf/cm 2 with a desirability value of 0.84. The validation results are withdrawn from the three test samples resulted in an average tensile strength of 0.25 kgf/cm 2 where this value differed 1.2% from the predicted results. The validation results are considered acceptable because the value is still within the acceptable error threshold or below 5%.

“…[8][9][10] Compared to the traditional separation technology, membrane separation is more energy saving, easier to operate, and does not produce secondary pollution during the efficient separation of pollutant emissions; thus, it has great potential in the separation of water contaminants and water purication. [11][12][13] As a two-dimensional nanomaterial researched widely in membrane separation, graphene oxide (GO) has been considered a strong competitor for liquid separation owing to its monoatomic thickness, lamellar structure, good membraneforming ability, excellent mechanical strength and exibility, and easy mass production characteristics. [14][15][16] However, there is no strong interaction between adjacent GO layers, thus leading to an expanded GO membrane when dispersed in an aqueous solution, which seriously affects the performance of the GO membrane.…”

“…6 In spite of the blessed of 185 billion tons of coal reserves, total coal energy contribution is only 7.89% in the country. [8][9][10][11][12][13][14] Coal that contained high moisture content has the benefit of high volatile matter, low cost of mining, lower sulfur contents, heavy metals, and nitrogen. The conventional coal produces SO 2 , toxic volatile compounds, NO x , and particulate matter that is dangerous; therefore, clean fuels are emerging as alternatives, which can be recovered using different process.…”

Coal-water slurry (CWS) has been targeted as a promising fuel and an alternative to fuel oil. CWS has numerous advantages of low and convenient transportation and high solid content. Pakistan is going through a severe energy crisis and among the top 10 countries facing energy crises reported by the United Nations. Besides, Pakistan has become the top seventh country in coal reserves (i.e., 185 billion tones) after the discovery of huge lignite coal reserves in Thar, Sind province. Previous studies investigated the use of additives to enhance CWS properties at a low shear rate and its utilization accordingly. Particularly, the present work studied the high range of shear rate to improve the properties of CWS for transportation and combustion purposes. This study on the improvement in performance of rheology properties of CWS is conducted to improve the properties by cost-effective additives. The coal concentration varies from 20% to 60%, whereas runs were carried out with and without the costeffective additives. The results demonstrated that the coal slurry showed shearthinning property when viscosity was increased at high concentrations in the absence of additives. The addition of additive changed the rheological behavior from pseudoplastic to dilatant region. The presence of a high fraction of coal increased the apparent viscosity of CWS. The static stability test of all coal samples was performed using rod drop method at concentrations of 40% to 60%. The study found that stability was achieved earlier with a lower concentration of 40% as compared with higher concentrations of 50-60%. It is expected that this research would be helpful for the country facing adverse energy crises that badly affect the economy and other social aspects of human life.
