“…Such a loosely packed sponge-like structure is commonly found in the CHFM derived from waste ash due to large particle sizes [11,33]. Generally, the waste ash can exhibit the particle sizes of larger than 10 µm, whereas the sizes of pure metal oxide particles are much ner (usually about 1 µm) [5,18,34,35]. The particle size distribution curve in Fig.…”

Low-cost green ceramic hollow fiber membranes (CHFM) were successfully designed and fabricated from the industrial waste ash, palm oil fuel ash (POFA) via phase inversion-based extrusion/sintering techniques for water filter application. The extrusion process parameters such as suspension viscosity, air gap distance, and bore fluid flow rate were systematically explored to produce the membrane with the desired morphology. A high suspension viscosity would result in a small macro-voids structure. Moreover, a high air gap distance would induce fiber with long macro-voids structure, while a low bore fluid flow rate would lead to the formation of distorted lumen structure. The effect of sintering temperature towards CHFM was also studied in detail. An increase in sintering temperature improved the membrane bending strength, but also adversely affected the pure water flux due to lower porosity and higher tortuosity. The developed membranes achieved excellent bending strengths of > 75 MPa at relatively low sintering temperatures than the alternative ceramic counterparts, due to its high potassium oxide, K2O content, which acted as the low melting point sintering aid. The relatively low sintering temperature of POFA-derived CHFMs could reduce the energy consumption and sintering duration, which could be more economically attractive, as compared to their ceramic counterparts, thus benefiting industrial users.

“…When the wettability behavior occurs on a rough solid surface, the Wenzel model, the Cassie model, and the Wenzel and Cassie transient model are usually applied for determining the contact angle. When the liquid fully contacts with the rough surface and without any gap in the interface, the contact angle (

) calculates by using the following equation according to the Wenzel model [ 22 ] ( Figure 2 c):

where the roughness factor (R) is the ratio of the actual rough surface area to the geometrically projected area. Since the real area of rough surface is always larger than the projected area ( R > 1), the contact angle on a rough surface is typically larger than that on a smooth surface.…”

Oil spill on sea surfaces, which mainly produced by the oil leakage accident happened on tankers, offshore platforms, drilling rigs and wells, has bring irreversible damage to marine environments and ecosystems. Among various spill oil handling methods, using sorbents to absorb and recover spill oils is a perspective method because they are cost-effective and enable a high recovery and without secondary pollution to the ecosystem. Currently, sorbents based on biomass materials have aroused extensively attention thanks to their features of inexpensive, abundant, biodegradable, and sustainable. Herein, we comprehensively review the state-of-the-art development of biomass-based sorbents for spill oil cleanup in the recent five years. After briefly introducing the background, the basic theory and material characteristics for the separation of oil from water and the adsorption of oils is also presented. Various modification methods for biomass materials are summarized in section three. Section four discusses the recent progress of biomass as oil sorbents for oil spill cleanup, in which the emphasis is placed on the oil sorption capacity and the separation efficiency. Finally, the challenge and future development directions is outlined.

Generally, the waste ash can exhibit particle sizes of larger than 10 μm, whereas the sizes of pure metal oxide particles are much finer (usually about 1 μm) [5,18,34,35]. The particle size distribution curve in Figure 3 shows that the majority of the POFA particles exhibited sizes ranging from 2.8 μm to 25.8 μm with a mean size of 8.0 μm.…”
