“…It is obvious that the performance of the regenerated TiO 2 /porous glass-H is repeatable and comparable to that of the original TiO 2 /porous glass-H. Compared with other studies using acetonitrile to extract sulde, 57,58 the heat treatment method for TiO 2 /porous glass-H can effectively avoid the use of toxic materials, which can be a very promising method for industrial applications with reduced cost and increased recyclability.…”

“…3e. The length of the mixing coil of 160 to 200 cm provides an additional period to mix the solvent with the crude oil which increases the process efficiency [Aghaei et al, 2020]. Moreover, the time parameter increases the efficiency of the sulfur removal process positively.…”

Sour crude oil is the crude oil that contains a high level of sulfur impurity. It can be toxic and corrosive. Before this lower-quality crude can be processed into other crude oil derivatives, the sulfur content must be reduced, raising the processing cost. A homemade semi-automated multipumping flow analysis system was constructed, consisting of several parts available on the local markets and at low economic costs to decrease the sulfur content of crude oil samples collected. The central composite design (CCD) and response surface methodology (RSM) have been used for modeling and optimization. The effects of the operational parameters, including polar and nonpolar solvent types, solvent flow rates (10-40 ml/min), mixing coil lengths (120-200 min), temperature (30-60 °C), and solvent entry time to the system (0-60 sec) were studied. Experimental and theoretical applications were made to determine the optimal sulfur content, which came out to be 1.438 and 1.395 wt.%, respectively. This system evaluated the effectiveness of the sulfur removal content for actual heavy crude oil by experimentally and theoretically to be 65.73 and 66.75% respectively. The semi-automated system was applied successfully to reduce the sulfur content in a highly sensitive and accurate way.

“…[45] Exposure of these solvents to the environment may cause severe problems for aquatic life and public health, and applying them in the fabrication of conventional membranes contradicts the environmental aspects of water and wastewater treatment. [71,72] On the other hand, the fabrication of 3D-printed membranes is a solvent-free process, which could also donate special features to the membranes with the minimal use of modifying chemical additives. The possibility of designing membranes with minimal use of added chemicals and recycling the 3Dprinted materials for the successive cycles shows the high potential of 3D-printed membranes in water and wastewater treatment plants.…”

It is widely acknowledged that three-dimensional (3D) printing or additive manufacturing will revolutionize many industries. However, the broad implications of 3D printing on water treatment membranes are not appreciated. 3D printing will transform the traditional membrane fabrication methods, reducing costs and industrial waste from manufacturing processes, with substantial benefits to treatment performance. In particular, 3D printing provides a high potential for radical decentralization. Remote communities, hospitality resorts, military bases, and oil and gas extraction operations could significantly benefit from the on-site fabrication of membrane units tunable to their specific wastewater challenges. Acute drinking water contamination events, like those associated with toxic by-products from algal blooms, chemical spills, forest fires, and extreme weather, cause adverse health effects on humans and shutdowns of piped water supply. 3D printing of customized membranes provides an opportunity for a fast response to such disastrous events. These membranes could be ready for installation within hours, with the vendor's role more akin to a software company installing a patch than the traditional approach, with major considerations for hardware availability, timeline, and supply chain. Despite these clear and potentially transformative advantages, 3D printing of membranes is not a panacea; countless aspects need to be taken into consideration for the successful implementation of this emerging technology. The full deployment of 3D-printed membranes in water and wastewater treatment can be achieved by extending the variety of printable materials, improving the speed and resolution of printing, creating nanoscale pores, reducing the fabrication costs, and improving the mechanical properties of the resulting membranes.
