“…If the EPS can be recycled into a useful submicron fiber for which large lengths are produced per mass of polymer then the economics may be more favorable. The electrospinability of the recycled EPS was demonstrated in a previous paper [1]. The aim of this paper is to present the effects of amount of EPS subµm fibers added to the glass fiber media on the pressure drop and the separation efficiency in liquid-liquid coalescence filter performance.…”

“…In many applications, dispersions of water drop sizes of less than 100 µm are very difficult to separate. Coalescence filtration can be economical and effective for separation of secondary dispersions [1][2][3][4][5]. There are three main steps of the coalescence process.…”

“…One important factor that controls the performance of a filter medium in the separation is the fiber size. Filter media with large fiber contact areas per unit volume generally perform better than media with lesser surface areas [1][2][3][4][5][6][7][8][9][10][11].…”

“…Many attempts have been made to determine the critical velocity at which the effluent concentration of the dispersed phase exceeds a fixed value. Coalescence media with larger fiber contact areas per unit volume generally outperform media with smaller surface areas [24]. Pressure drop is an important hydrodynamic parameter for the design of a packed bed [4].…”

Fibrous-bed coalescers are commonly used to separate oil-in-water emulsions, and some factors significantly affect the separation performance. To achieve a fundamental understanding of the colloidal physical phenomenon and to predict the coalescence efficiency are challenging tasks because of the complex interplay among the governing parameters. Here, two types of commercial oleophilic fibers were employed to study the influence of critical factors on the separation performance, including the packing density, the specific surface area, the bed depth, the superficial velocity, and the inlet oil content. An industrial-scale experiment was also carried out on an offshore platform. The collected industrial data will be useful to further the application of the oleophilic-fiber bed in oily wastewater treatment.

The aim of this article is to provide an overview of nanofibers' properties, functionality enhancement, and applications. In order to achieve this, the significant properties of nanofibers were first demonstrated. Based on this demonstration, it was concluded that nanofibers have potential use for a wide range of applications. Additionally, the functionality enhancements of nanofibers through their physical and chemical modifications were reviewed. This functionality enhancement process helps to effectively apply the nanofibers in the engineering and medical fields. The applications of nanofibers in different hi‐tech engineering and medical fields were described. This article identified various gaps and limitations associated with nanofibers' applications and suggested further research directions. Based on this article, it has been found that nanofibers could be produced with several properties and structures including shape, size, and strength. As a result, nanofibers could be applicable in high‐tech engineering and medical sectors such as tissue engineering, sensors, and enzyme carrier. As nanofiber is a porous media, the applicability of nanofibers could be widened in different fields like protective apparel, lightweight military products, and so on. This article can help polymer engineers to improve and extend the applicability of nanofibers in evolving engineering and medical fields. In turn, this article could help to advance the field of high‐tech engineering and medical field for better human life.
