“…Membrane technology, especially pressure-driven separation operation, requires a membrane with characteristics such as resistance to transmembrane pressure from 1 to 100 bar, temperature resistance, and the ability to recycle the membrane through periodic cleaning [ 1 , 4 ]. Membrane performance is measured as flux water and selectivity.…”

“…Membrane technology is a helpful alternative to separation process (i.e., microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO)), and to specific applications such as heavy metal remediation, seawater desalination, gas purification, pathogen removal, wastewater treatment, juice clarification, high added value compounds recovery, chemical transformations in catalytic membranes, membrane bioreactors, dialysis, drug release, and cell culture [ 1 , 2 , 3 , 4 ]. However, the increase of environmental issues and affections on human health derived from the preparation and use of solid polymeric materials made from fossil sources is nowadays a general concern; some of them are global warming, marine ecotoxicity, human carcinogenic and no carcinogenic toxicity, high energy demand, and land use [ 2 ].…”

Nowadays, membrane technology is an efficient process for separating compounds with minimal structural abrasion; however, the manufacture of membranes still has several drawbacks to being profitable and competitive commercially under an environmentally friendly approach. In this sense, this review focuses on bio-based polymeric membranes as an alternative to solve the environmental concern caused by the use of polymeric materials of fossil origin. The fabrication of bio-based polymeric membranes is explained through a general description of elements such as the selection of bio-based polymers, the preparation methods, the usefulness of additives, the search for green solvents, and the characterization of the membranes. The advantages and disadvantages of bio-based polymeric membranes are discussed, and the application of bio-based membranes to recover organic and inorganic contaminants is also discussed.

Cell separation using microfluidics has become an effective method to isolate biological contaminants from bodily fluids and cell cultures, such as isolating bacteria contaminants from microalgae cultures and isolating bacteria contaminants from white blood cells. In this study, bacterial cells were used as a model contaminant in microalgae culture in a passive microfluidics device, which relies on hydrodynamic forces to demonstrate the separation of microalgae from bacteria contaminants in U and W-shaped cross-section spiral microchannel fabricated by defocusing CO2 laser ablation. At a flow rate of 0.7 ml/min in the presence of glycine as bacteria chemoattractant, the spiral microfluidics devices with U and W-shaped cross-sections were able to isolate microalgae (Desmodesmus sp.) from bacteria (E. coli) with a high separation efficiency of 92% and 96% respectively. At the same flow rate, in the absence of glycine, the separation efficiency of microalgae for U- and W-shaped cross-sections was 91% and 96%, respectively. It was found that the spiral microchannel device with a W-shaped cross-section with a barrier in the center of the channel showed significantly higher separation efficiency. Spiral microchannel chips with U- or W-shaped cross-sections were easy to fabricate and exhibited high throughput. With these advantages, these devices could be widely applicable to other cell separation applications, such as separating circulating tumor cells from blood. Graphical Abstract
