🌍 New Publication from Kerry McPhedran, the Team Leader in Cyclic Water! 💧 We are thrilled to announce the publication of our latest research in advanced wastewater treatment. This study demonstrates that the Fe(III)/WS2/peroxymonosulfate (PMS) system can achieve an impressive 97% removal rate of cyclohexanecarboxylic acid (CHA) within a short time. This breakthrough has significant implications for the treatment of naphthenic acids (NAs) prevalent in petroleum industrial wastewater. Furthermore, our system demonstrated excellent catalytic performance, reusability, and anti-interference capacity, achieving efficient degradation of commercial NAs mixtures. This advancement paves the way for simple and economical engineering applications in wastewater treatment.

Hydrotropes are an essential ingredient of cleaning and laundry products, serving to reduce excessive thickening of the former and to improve the dirt-removing action of the latter. Hydrotropes are molecules traditionally with a structure of a short hydrocarbon chain, often aromatic, combined with a polar group that in the early days of their development was ionic. Neuberg described the hydrotropes as compounds enhancing the solubility of organic compounds in water and investigated a large number of them. #Chemistry #Cosmetics #Surfactants #Hydrotropes

Very proud to announce the publication of Hydrothermal Destruction and Defluorination of Trifluoroacetic Acid (TFA) in Environmental Science & Technology as of today! 🎉 Congratulations to Conrad Austin, Anmol Purohit, Cody Thomsen, Timothy Strathmann, and Igor Novosselov for conducting an excellent study and once again proving that HALT works exceptionally well to destroy PFAS. 👏 In this work, we demonstrate several crucial aspects of the HALT technology: 1) TFA, the simplest and smallest perfluorocarboxylic acid, can be destroyed under relatively mild HALT conditions (low temperatures and low chemical dosing). This has huge implications for the practical implementation of HALT systems for TFA treatment applications, as the energy and chemical costs can be kept much lower. 2) The alkaline amendment (the "AL" in HALT) is crucial to prevent the production of volatile organofluorine (VOF) gases under hydrothermal conditions. Without an alkaline amendment, TFA is converted into fluoroform, a potent greenhouse gas with >11,000x the global warming potential of CO2. The alkaline conditions of HALT are one of the reasons why we can fully "mineralize" PFAS (convert PFAS to inorganic fluoride) and one of the reasons why HALT, in a PFAS destruction context, is superior to similar technologies such as pyrolysis, gasification, and HTL, which all have the potential to convert PFAS into VOFs. 3) Building on that idea, our ability to mineralize fluoroform, (a.k.a. freon, or R-22) with HALT demonstrates that we can use HALT to mineralize and treat legacy hydrofluorocarbon (HFC) refrigerants at mild conditions. This presents a huge opportunity for a greener HFC disposal option, over the current practice of incineration. Well done team, proud to be part of this effort. #PFAS #endingPFAS #science #environment #refrigerants #cleantech https://lnkd.in/gGKebPSn

Mellifiq Collaborates on German Government-Funded Project This groundbreaking project focuses on the development of a modular air purification unit. This cutting-edge system is designed to address challenging environments such as sewage treatment plants, where sulfur gases and mercaptans are prevalent. Project Overview: The purification process of our new unit occurs in three sophisticated stages: • Desulfurization – Managed by our German partner, this stage targets the removal of sulfur compounds. • Oxidation – Mellifiq’s ozone technology is used to handle any volatile organic compounds (VOCs) that pass through the sulfur filter. • Polishing – Mellifiq’s Nodora gas filters, as the final stage, ensure the thorough elimination of any remaining impurities, providing pristine air quality. Funding and Timeline: This project has received partial funding from a major German governmental research funding agency, highlighting its significance and potential impact. We are set to begin semi-lab scale testing in 2024, progressing to field and full-scale applications by 2025. Aim and Impact: The primary application of this unit will be in settings with high concentrations of sulfur gases. The integrated approach of desulfurization, oxidation, and polishing is specifically tailored to meet upcoming environmental requirements and provide a comprehensive solution that enhances both air quality and operational efficiency. #Mellifiq #Cleantech #AirPurification #Innovation #Desulfurization #Nodora

Our freshly-baked publication on the "Effects of Salinity on Glycerol Conversion and Biological Phosphorus Removal by #Aerobic_Granular_Sludge" in #Water_Research 🔬 📚 In this work, we provided insights into the effect of salt on the operation and stability of the #EBPR and #AGS processes. The findings suggest that maintaining a balanced cation ratio is likely to be more important for operational stability than absolute salt concentrations in these processes. This work would not have been possible without the invaluable contributions of Fleur de Clercq, Martin Pabst, Dimitris Xevgenos, Mark van Loosdrecht, and Mario Pronk as co-authors! https://lnkd.in/esm3fBfw
