|Advances in Membrane Technologies for Water Industry Applications|
|1.00pm||The pathway of developing and commercializing a technology inspired by mother nature: Forward Osmosis.||
Reverse Osmosis (RO) has been widely applied for seawater desalination to secure affordable and sustainable water supply in Singapore. In contrary to RO, Forward osmosis (FO) is an emerging separation process that has received huge attention in academic and industrial development, however, the lack of optimized FO membrane impeded its practical application. The talk covers how the NTU team analyses of desired characteristics of FO membrane, fabrication of hollow fiber membrane with optimized structure as well as scaling-up modules from laboratory into industrial size. Scaling-up membranes from basic research is by no means a trivial matter, its success relies not just on engineering alone, but on many times going back to the drawing board to come up with solutions based on strong fundamental sciences.
FO was initially deemed to be a low-energy process for desalination as opposed to RO, it is now believed that FO alone will not be able to turn saline water into fresh water without secondary processing to harvest clean water from diluted draw solution. NTU team, however, ideates a new use case that regarded concentrated liquids as the product, instead of the water extracted by draw solutions. By departing from the original goal of potable water extraction, an extensive range of possible use cases unraveled leads to the setup of Aromatec in 2018 by Prof Wang and Dr Shi as co-founders. Apart from their present focus on the concentration of high-value liquid products in F&B, Aromatec is also exploring FO application in fragrances and pharmaceuticals.
|Towards efficient and fouling-resistant membranes for water treatment: Chemical, physical and machine learning pathways.||Permeability, selectivity and fouling resistance are three major properties of membranes for water treatment. Many efforts have been made over decades to enhance membrane performances from the three perspectives, which ultimately contribute to higher process efficiency. In this talk, I’ll introduce our recent work in this area via chemical, physical and machine learning approaches, in particular for nanofiltration and reverse osmosis membranes. Our progress in bringing highly permeable RO membranes from lab to pilot (4-inch) scale will be highlighted, biomimic patterned membranes and their impact on fouling will be discussed, and machine learning guided membrane development will be introduced.|

|De Nora AOP Solution|
|2.20pm||De Nora AOP Solutions||
Learn about De Nora Water Technologies Advanced oxidation Process (AOP) solutions and how they can be applied to water reuse and other challenging applications. De Nora offers Ozone and UV based AOP solutions as well as multi-barrier process solutions which include biologically active filters (BAF). The AOP process produces hydroxyl radicals, a very strong oxidants, which are used to break down large organic molecules. When further treatment is needed, a BAF will biologically oxidize the remaining organic molecules thereby lowering overall Total Organic Carbon (TOC). Learn how these technologies can be used to remove contaminants of emerging concern (CEC’s) as well as reduce harmful disinfection byproducts (BDP’s) in your treatment system.
