The massive amount of industrial sludge produced annually poses an environmental concern, and improper sludge disposal may harm the environment. To address this issue, sludge has been converted into a cost-effective adsorbent for treating wastewater containing dyes. This study aims to modify the coffee sludge-based adsorbent using various treatment...

The extensive use of water in the textile industry results in the production of significant volumes of effluent-containing dyes, posing both economic and environmental concerns due to their harmful impact. Hence, the removal of dye from wastewater is very important for environmental protection and other aspects of well-being. Solvent extraction eme...

Dyes containing waste streams are the most common pollutants found in wastewater, posing a severe threat to both the ecosystem and the environment. Adsorption emerges as one of the most effective and widely applied treatments for removing dyes due to its simple operation, high efficiency, and low cost. Sodium alginate, as a biopolymer, is one of th...

Electrocoagulation was demonstrated for the effective removal of organic dyes, waxes, and sodium silicate from batik wastewater. For the first time, the reuse of an electrocoagulated batik sludge (EBS) by converting it into an adsorbent for Acid Red 18 (AR18) dye removal is reported. The EBS sample was dried in an oven to produce the raw EBS (REBS)...

Solid wastes are one of the major environmental problems and creative utilization could hold the key to the solution. An attempt was made in this study to transform waste from steel containers (WSC) into efficient electrodes for the removal of Acid Red 18 dye from water through an elec-trocoagulation (EC) process. A 1.1 L batch monopolar EC cell wi...

Batik wastewater contains organic dyes, waxes, silicate, etc. that are environmentally problematic. Two plain waste aluminum cans were used as electrodes in a batch electrocoagulation (EC) process to remove color, chemical oxygen demand (COD), and silica from batik wastewater. Response surface methodology based on the central composite design was u...

This work compares commercial aluminium electrode for use in the treatment of wastewater by electrocoagulation process against waste aluminium cans electrode. The applicability of the waste aluminium cans electrode was tested for decolorization of Acid Red 18 dye as a model pollutant. The batch electrocoagulation process using both types of electro...

Semiconductor processing facilities regularly emit wastewater with fluoride concentrations exceeding 100 mg/L which can cause major health issues in the local population. This research aims to address this issue by optimising an electrocoagulation-adsorption (EC-AD) process using two aluminium electrodes and activated carbon. The applied voltage (5...

This study investigated the effect of Coconut Pulp (CP) fiber on the mechanical properties of Ethylene Propylene Diene Monomer (EPDM). CP filled EPDM composites were prepared by using a mixer and hot press. There are four types of the composition of CP, 10, 20, 30 and 40%. In this study, the tensile strength, modulus of elasticity, elongation at br...

In modern application in automotive and aerospace engineering especially in defense vehicle, underwater vehicle and aircraft used Metal and Polymer Composites as the main materials in their invention parts. The joining strength may increase if the contacted surface area between two materials is also increase, in this case, the relationship of adhes...

Bagasse (sugar cane fibre) was used as organic filler in polypropylene (PP) composites. In this study, it focused on the improvement of mechanical properties and swelling behaviour of polypropylene (PP) filled bagasse (sugar cane fibre) composites by creating more adherent bonding between bagasse filler/PP matrix using acrylic acid as surface modif...
