“…The pseudo-first-order and pseudo-second-order models were selected to characterize, and the results are shown in Figure 5 and Table 1 . The pseudo-first-order [ 28 ] and pseudo-second-order kinetic models [ 29 ] are worked out in Equations (3) and (4), respectively.

where q e (mg g − 1 ) is the amount of dye adsorbed at equilibrium, q t (mg g − 1 ) denotes the amount of dye adsorbed at time t (min) and K 1 (min − 1 ) is the rate constant of the pseudo-first-order model, K 2 (g mg − 1 min − 1 ) is the rate constant of the pseudo-second-order model.…”

As an edible oil, palm oil is also safe and reliable in dyeing, and the residual palm oil after dyeing can be recycled and used continuously, which is green and environmentally friendly and has great research prospects. In this research, raw ramie yarn, used for traditional grass cloth, was dyed in a palm oil medium using Reactive Blue 194. Studying the adsorption and diffusion behaviour in the dyeing process is necessary. Additionally, the kinetics and isotherm model of dyeing raw ramie yarn with Reactive Blue 194 in palm oil is studied, and the adsorption behaviour between them is discussed. For a better understanding, the raw ramie yarn dyeing adsorption behaviour was also carried out in a water medium. It was found that the dyeing rates in palm oil are distinctly faster than in water. Kinetics data suggested that the pseudo-second-order model fitted for both dyeing mediums (palm oil and water) of the adsorption of the Reactive Blue 194 dye onto raw ramie yarn. Afterward, the adsorption isotherms’ results denote that the Langmuir model was suitable for palm oil dyeing medium while the Freundlich model was suited for water medium. Overall, this study has demonstrated that raw ramie yarn dyeing in a palm oil medium could be a sustainable colouration route for textile fibres with a greater dye exhaustion percentage.

“…The latest generation of membranes is known as electrospun nanofiber membranes (diameter usually less than 100 nm) and have the potential to offer an advancement in the treatment of water and wastewater. In electrospinning, the electrostatic forces help create thinner fibers whereby a high voltage is delivered to a syringe containing a polymer solution or melt that assist in collecting the fibers on a ground plate [109,110]. The produced nanofiber membrane has a significant water permeability and flexibility, as well as high porosity, a large surface area to volume ratio, and high-water absorption.…”

Water is needed for food processing facilities to carry out a number of tasks, including moving goods, washing, processing, and cleaning operations. This causes them to produce wastewater effluent, and they are typically undesirable since it contains a high volume of suspended solids, bacteria, dyestuffs, salts, oils, fats, chemical oxygen demand and biological oxygen demand. Therefore, treatment of food industry wastewater effluent is critical in improving process conditions, socio-economic benefits and our environmental. This short review summarizes the role of available membrane technologies that have been employed for food wastewater treatment and analyse their performance. Particularly, electrospun nanofiber membrane technology is revealed as an emerging membrane science and technology area producing materials of increasing performance and effectiveness in treating wastewater. This review reveals the challenges and perspectives that will assist in treating the food industry wastewater by developing novel membrane technologies.

“…Textile dyeing and nishing industries are considered one of the greatest industrial polluters because they discharge a large amount of wastewater containing harmful dyes affecting the environment and human life. 1,2 In this regard, over the past several years, technologies such as adsorption, 3,4 Fenton catalytic systems, 5,6 and membranes [7][8][9] have been applied to treat these complex wastewater effluents; however, these methods are still questionable in terms of sustainable development in the textile industry. Therefore, waterless dyeings, such as dyeing in supercritical uid, [10][11][12] silicone oil, [13][14][15][16][17] liquid paraffin oil, [18][19][20] plant oil, 21,22 and ethanol, 23,24 have been studied as an example of a cleaner dyeing method to reduce water pollution.…”
