This session focuses on innovations and experiences related to the treatment of challenging wastewaters. Such wastewaters are considered particularly difficult to manage due to their high fouling potential, the presence of hard-to-remove components such as persistent micropollutants, or unconventional pH and salinity levels.

Wetsus: Challenging Water

Xiao Zhang is a PhD researcher at Wetsus and University of Twente. Her research focuses on developing stable polyelectrolyte multilayer nanofiltration membranes, which are designed to perform effectively under harsh process conditions, such as high salinity and extreme pH. These advanced membranes aim to provide solutions for the efficient treatment of various industrial streams.

I am a molecular biologist-microbiologist with an interest in applying microorganisms to environmental and industrial processes. During my PhD research, I have focused on aerobic granular sludge, a biofilm used in biological wastewater treatment. I studied the microbial activity and composition of the biofilm and the conversions of organic macromolecules during the wastewater treatment process. I am interested in combining advanced techniques to study mixed microbial communities and their in situ behavior. With a little help from microorganisms, I hope to contribute to transitioning to a sustainable society.

From my role as Permitting Lead with HyCC, we are applying for the necessary permits for future green hydrogen production sites in the Netherlands. This is entirely in line with my personal motivations, including my desire to contribute to the energy transition. The energy transition will not succeed through the success of a single company but through the partnership of various parties within the Netherlands. We also aim to limit water consumption, for example, by exploring the possibility of using RWZI effluent in the production process when permissible.

Mohamed Mokhlef's journey into the water industry wasn’t a straightforward one. As a young man, he dreamed of a career in media, believing it held the power to influence minds and drive change. But a conversation with his father changed everything. He learned that billions of people worldwide lack access to clean water and proper wastewater services—a silent crisis with far-reaching consequences. That realization shifted his perspective and set him on a path he never imagined.
Today, Mohamed leads IWTE, a company founded by his father in 1992. What started as a small family business has grown into a regional leader in water treatment under his leadership. Since 2021, he has focused on transforming IWTE into a modern, forward-thinking organization, opening its first international branch in Saudi Arabia, working on ISO certifications, and preparing to publish its first ESG report.
Alongside IWTE, Mohamed founded Meyahh, a startup designed to empower small contractors, support local manufacturers, and bring more investment into the water industry. He believes collaboration and innovation are key to solving the region’s water challenges.
Mohamed’s journey has taken him to over 15 countries and 96 cities, where he’s met hundreds of experts and seen firsthand the issues that need solving. His focus is clear: to turn challenges into opportunities and to help create a more sustainable future for the Middle East and Africa.

Autobiography of Oleg Dubov
My name is Oleg Dubov, and I was born on August 11, 1982, in Saint Petersburg, Russia. Throughout my career, I have dedicated myself to scientific research and technological development in water treatment, plasma applications, and chemical engineering. My academic background and extensive professional experience have led me to a fulfilling career in both academia and the private sector.
Education and Academic Achievements I hold a PhD in Nanoscience, Materials, and Chemical Engineering from the Universitat Rovira i Virgili in Catalonia, Spain. My doctoral research focused on the development of innovative materials and technologies for water treatment, including electrochemical processes and advanced oxidation methods. Prior to that, I earned a Master’s degree in Global Management of Innovation and Technology from Lappeenranta University of Technology, Finland, where my thesis explored the profitability of recycling small electronic devices for the recovery of critical materials. I also hold a Bachelor’s degree in Chemistry from Saint Petersburg State University, where I specialized in physical chemistry and membrane methods for water treatment.
Professional Experience Currently, I serve as a co-founder and Chief Technical Officer at FIDCHEM S.L., a company based in Spain that specializes in the application of cold pulsed corona discharge plasma for water treatment. Our primary focus is on the removal of persistent organic pollutants such as PFAS (per- and polyfluoroalkyl substances) and polychlorinated pollutants, as well as disinfection of water. Simultaneously, I work as a postdoctoral researcher at the Universitat Rovira i Virgili, where I continue my research on PFAS removal using advanced plasma-based technologies.
Previously, I held the position of Advanced Researcher at Eurecat, the Catalonian Technology Centre. In this role, I was responsible for public and private projects related to chemical and electrochemical advanced oxidation of water contaminants, as well as the development of electrochemical sensors for water impurities.
From 2011 to 2018, I served as the Head of the R&D Department at the BTP Group of Companies, which operates in the field of water and wastewater treatment. During my time there, I led innovative projects focused on advanced oxidation processes, zero liquid discharge technologies, heavy metal removal, and the adaptation of various treatment methods to industrial wastewater challenges. My responsibilities included project management, technical analysis, data modeling, and collaboration with research institutions for joint projects.
My earlier professional experience includes working as a research chemist and research technician at Aquaphor Corporation, one of Russia’s leading producers of household water treatment systems. I contributed to the development of new antiseptic materials and methods for water sterilization, as well as the synthesis of fiber-selective ion exchange materials for heavy metal removal.
Research Interests and Contributions My research interests lie in the field of chemical and electrochemical water treatment, with a particular focus on plasma applications for the removal of persistent organic pollutants. Over the years, I have conducted numerous R&D projects related to membrane technologies, advanced oxidation processes, and electrochemical sensing. My work has resulted in several patents, including methods for producing nitrogen-rich carbon nitride coatings, mobile water purification stations, and devices for backwash water treatment.
Throughout my career, I have presented my research at international conferences, published in peer-reviewed journals, and collaborated with industrial partners and academic institutions. I am passionate about bridging the gap between fundamental research and practical industrial applications, especially in the field of water treatment technologies.
Skills and Expertise I possess a broad range of skills, including project management, process optimization, and hands-on laboratory work. My expertise spans various chemical analysis techniques, such as HPLC, gas chromatography, and FTIR spectroscopy, as well as electrochemical methods and surface analysis. I am proficient in programming languages like Python for data analysis and automation and have experience with microcontroller platforms such as Arduino and Raspberry Pi.
In addition to my technical skills, I am fluent in English and have a strong command of Spanish. My native language is Russian.
Personal Motivation My professional journey has been driven by a deep interest in addressing global environmental challenges, particularly in the realm of water treatment. I am committed to developing sustainable solutions that can help mitigate the impact of industrial pollutants on water resources. My work at FIDCHEM S.L. and my ongoing research at Universitat Rovira i Virgili are testaments to my dedication to this cause.
In conclusion, my career has been shaped by a combination of scientific curiosity, practical problem-solving, and a commitment to making a positive impact on the environment. I continue to seek new opportunities to advance my knowledge and contribute to innovative solutions in the field of water treatment and environmental sustainability.
