The scarcity of freshwater resources in many regions the world has contributed to emergence various technologies for treating and recovering wastewater reuse industry, agriculture, households. Deep treatment from oils petroleum products is one difficult tasks that must be solved. Among known technologies, UF membranes have found wide industrial application with high efficiency removing pollutan...

We discuss the influence of surface structure, namely the height and opening angles of nano- and microcones on the surface wettability. We show experimental evidence that the opening angle of the cones is the critical parameter on sample superhydrophobicity, namely static contact angles and roll-off angles. The textured surfaces are fabricated on silicon wafers by using a simple one-step method...

The degree of meat adhesion to different kinds of plastic casings was examined in retort sterilized fish sausages. It was found that the plastic casings of great wettability such as polyvinylidene chloride, polyvinylidene fluoride, polyester and polyamide brought about greater meat adhesion than the ones of low wettability such as polyethylene and polypropylene. If polyethylene casing was modif...

Hydrophilisation of polyester textile materials has been investigated over the last twenty years using low-pressure and atmospheric plasmas. According to these studies, wettability and capillarity of fabrics can be significantly improved depending on the process gas used. In the present study, the effects of low pressure O 2 and NH 3 plasma on the morphology and topometry of fabrics on four dif...

In a recent theoretical study, Li and Firoozabadi showed that if the wettability of porous media can be altered from preferential liquid-wetting to preferential gas-wetting, then gas well deliverability in gas condensate reservoirs can be increased. In this paper, we present the results that the wettability of porous media may indeed be altered from preferential liquid-wetting to preferential g...

The presence of oily wastewater poses a significant threat to both the ecological environment and public health. In order solve this problem, design preparation an efficient oil–water separation membrane is very important. Metal–organic frameworks (MOFs) are currently promising material for due their tunable wettability, adjustable pore size also low density, high porosity, surface area. Theref...

The surface structure and properties of a membrane largely determine its in-service performance during filtration process. Polyvinylidene fluoride (PVDF) hydrophobic is widely used in the separation oily wastewater because mechanical strength, but susceptible to oil fouling, whereas hydrophilic membranes are easily damaged water due their wettability resistant oil. advantages two then combined ...

Chemical agglomeration can reduce the particulates (including PM2.5) concentration emitted from fly ash particulates and the wet flue gas desulfurization (WFGD) system. However, the calcium-based slurries affect the regulation of agglomeration compared to water, in particular, the wettability of the particulates and the viscosity of the calciumbased slurry. The wettability and the viscosity are...

Capillary pressure/saturation data are often difficult and time consuming to measure, particularly for non-water-wetting porous media. Few capillary pressure/saturation predictive models, however, have been developed or verified for the range of wettability conditions that may be encountered in the natural subsurface. This work presents a new two-phase capillary pressure/saturation model for ap...

Graphene as one type of well-known solid lubricants possesses different nanotribological properties, due to the varied surface and structural characteristics caused by different preparation methods or post-processes. Graphene nanosheets with controllable surface wettability and structural defects were achieved by plasma treatment and thermal reduction. The nanotribological properties of graphen...
