Revolutionary membrane tech separates 97% oil from water with 99.9% purity | Researchers in China have unveiled a new, highly effective technique for separating oil and water mixtures.
Zhejiang University researchers have developed a new membrane-based technology called the Janus Channel of Membranes (JCM).
The confined space between the membranes amplifies the separation process, leading to high recovery rates of up to 97% for oil and 75% for water, with minimal impurities. “Guo et al. stacked a hydrophilic and a hydrophobic membrane one in front of the other to form a square channel between them, with a size that can be varied between 4 and 125 millimeters,” noted the study paper. While conventional separation technologies typically isolate oil or water from an emulsion, this innovative method enables the recovery of both components.
