Electrodialysis (ED) is a membrane-based separation process that exploits the selective migration of ions under the influence of an electrical driving force. It removes ionized species from liquid solutions using alternating cation- and anion-exchange membranes, arranged between two electrodes. When a direct current is applied, cations move toward the cathode and pass through cation exchange memb
The textile industry generates vast wastewater containing synthetic dyes and polymeric additives like poly(vinyl alcohol) (PVA), which pose serious environmental challenges. Conventional treatment methods struggle to remove these contaminants while enabling resource recovery. PVA, widely used as a textile sizing agent, increases treatment complexity, while reactive dyes like Reactive Yellow 145 ar
IntroductionWater scarcity is a growing problem, with estimates showing that 40% of the world’s population could face water shortages by 2030. This issue is even worse because only 3% of the Earth’s water is freshwater, while 97% is seawater. Finding better ways to save and use water is critical to solving this problem. At the same time, renewable energy is essential for reducing carbon emissions
Stormwater management is essential for preventing urban flooding and protecting water quality in receiving bodies. Traditionally viewed as a nuisance, stormwater is now being re-evaluated as an alternative resource for non-potable uses such as toilet flushing and irrigation through rainwater harvesting systems (RWHS). Within the European Union's Horizon 2020 project REWAISE, pilot studies with cer
Industrial dairy membrane processes require frequent cleaning due to hygienic and regulatory demands and lowered efficiency, caused by fouling. This decreases the membrane life cycle and consumes large volumes of rinsing water and cleaning solution. Therefore, the aim of this project is to increase the understanding of membrane fouling and cleaning and to apply this knowledge to develop more ene
More than 21 million tons of cheese whey are produced annually worldwide, posing an environmental risk if not properly managed. Due to widespread lactose intolerance, cheese whey, which contains lactose, can pose health problems for many individuals. Thus, the management of the cheese whey is necessary to avoid environmental and health problems. This study presents a sustainable approach for whey
Ultrafiltration (UF), a widely utilised membrane-based process used in the dairy industry, is crucial for standardising milk constituents, especially proteins. However, depending on the filtration set-up, the extent of the physicochemical properties of the concentrate can be modulated. This study compares the impacts of two UF configurations, cross-flow (CF-UF) and dead-end (DE-UF), on the mineral
This study explores the potential for stormwater reuse to reduce potable water consumption for toilet flushing and laundry. A pilot project utilizing silicon carbide (SiC) membranes in Lund achieved significant reductions in contaminants, with permeate meeting EU standards for non-potable applications.A permanent (SiC) membrane installation in Malmö demonstrated a 38% reduction in potable water us
Introduction:Fava beans are becoming an increasingly popular and viable crop, offering a nutritious option for innovative plant-based food products. Despite their potential, fava beans remain underutilized in the food industry, with their primary use still being as animal feed [1]. However, fava beans are an interesting base material for producing plant-based milk alternatives. While soy milk curr
Introduction. Fava beans are an increasingly popular and viable crop, and an excellent nutritious choice for novel plant-based food products. Fava beans are industrially underexploited as a food ingredient and are today mainly used as animal feed [1]. However, fava beans are an interesting base material for producing plant-based milk. While soy milk dominates the legume-based beverage segment, the
Introduction. Building block chemicals, such as butanol, can be produced via fermentation and biobased feedstocks as a more sustainable alternative compared to the current petrochemical methods. However, the butanol fermentation is subjected to low product titres (<20 g/L) due to product inhibition of the bacteria [1]. To overcome this continuous fermentation can be applied, as it offers considera
Introduction. Salinity gradient energy (SGE) originates predominantly in estuaries, where freshwater rivers meet seawater. The energy available from the mixing of these solutions results from the difference in concentration between them. While oceanic waters typically maintain similar salt concentrations, those confined within semi-enclosed basins exhibit vari
Introduction.Kraft black liquor is a side-stream produced during the kraft pulping process containing lignin, hemicelluloses and cooking chemicals. The stream is usually evaporated and burned in the recovery boiler to recover the cooking chemicals and generate energy. The mill is, however, often/sometimes limited by recovery boiler capacity, and removing some of the lignin from kraft black liquor
Introduction. Electrodialytic processes have become relevant technology in promoting sustainability within the food industry. Bipolar membrane electrodialysis (EDBM) offers an efficient and eco-friendly alternative for skim milk (SM) acidification, eliminating the need for added acids that affect milk properties and mineral composition [1-2]. In this study, the fouling behavior of bipolar membrane
Introduction. Cellfion is a company developing PFAS-free membranes based on chemically functionalized nanocellulose. The membranes are highly tuneable and exhibit favourable properties such as high selectivity, low resistance and low swelling. Cellfion’s membranes have shown potential for use in different applications such as electrodialysis, fuel cells, electrolyzers, humidification syste
Fermentation intensification is crucial for the economic viability of biobased chemical production through fermentative routes, including a shift from batch/fed-batch to continuous fermentations to enhance volumetric productivity. This is especially relevant for the Acetone Butanol Ethanol (ABE) fermentation due to low productivities and concentrations caused by product toxicity. However, transiti
Recycling industrial wastewater is a significant challenge due to its complexity. However, achieving the global sustainable development goal 6—clean water and sanitation—requires suitable treatment technologies to upgrade and recycle water, thereby reducing drinking water consumption and water stress. This presentation focuses on two challenging wastewater streams:carwash and oily wastewater, demo
IntroductionThe pulp and paper industry is one of the most significant industrial sectors globally. Current pulp mills primarily focus on producing pulp fibers and electricity. By transforming traditional pulp mills into lignocellulosic biorefineries, they can become a cornerstone of a future circular bioeconomy. To achieve this, pulp mills must close their process loops and, in addition to fiber
IntroductionGlobal water scarcity necessitates innovative approaches to water treatment. Membrane technology has emerged as a key solution, demonstrating its effectiveness across a range of applications, from seawater desalination using reverse osmosis to wastewater treatment with membrane bioreactors. This presentation will introduce three novel water treatment concepts based on membrane technolo
Although Russian President Vladimir Putin is the only person who can end the war in Ukraine almost immediately, peace on the “Western Front” that he himself created is not necessarily just his free choice. The question is whether Putin and his circle of power can still afford a ceasefire with a neighboring country that they have plundered and destroyed – and to what extent. The answer is not only
