The economic impact of fouling in spiral wound membranes is not yet well explored. There has been an established assumption that the cost membrane processes significant, but this hypothesis thoroughly evaluated. We conducted analysis on seven full-scale installations, four nanofiltration (NF) and three reverse osmosis (RO), to estimate industrial plants. was calculated detail, including costs increase feed channel pressure drop, water permeability reduction, early replacement, extensive...
Ion exchange membranes could provide a solution to the selective separation of organic and inorganic components in industrial wastewater. The phenomena governing transport organics through IEM however, are not yet fully understood. Therefore, trace contaminants (TOrCs) as model for wide variety compounds was studied under different conditions. It found that absence salt external potential, chemical equilibrium is main driver TOrC-transport, resulting mainly charged TOrCs. When present, TOrCs...
Abstract Although seawater reverse osmosis (RO) is nearing its thermodynamic minimum energy limit, it still an energy-intensive process, requiring 2–3 kWh/m³ at a recovery of 50%. Pre-desalination the by electrodialysis (RED), using impaired water source, can further decrease this demand producing and reducing concentration. However, RED hampered initial high resistance fresh resulting in required membrane area (i.e., investment costs). In paper, new process presented that overcome cost...
The co-generation of electricity and electrodialysis seawater in a hybrid system is promising approach to overcome water scarcity. Reverse harvests energy from the salinity gradient, where used as high stream while secondary treated wastewater can be sustainable low stream. Treated contains organic micropollutants, which transported current research establishes connection between adsorption transport micropollutants ion exchange membranes, using cross-flow stack zero-current experiments. To...
In energy-efficient electrodialysis desalination processes, salt ions are transported from seawater (high salinity) to wastewater (low through ion-exchange membranes. Besides ions, also organic micropollutants can be in organics) organics). The transport mechanisms of membranes complex phenomena, and pH has a tremendous impact on them. Since variations operation common, it is crucial importance investigate its influence these mechanisms. Therefore, large pool nineteen various physicochemical...
Size exclusion chromatography with total organic carbon detection (HPSEC-TOC) is a widely employed technique for characterizing aquatic natural matter (NOM) into high, medium, and low molecular weight fractions. This study validates the suitability of HPSEC-TOC simplified yet efficient routine analysis freshwater its application within drinking water treatment plants. The investigation highlights key procedural considerations optimal results shows importance sample preservation by...
Long-term human Space missions will rely on regenerative life support as resupply of water, oxygen and food comes with constraints. The International Station (ISS) relies an evaporation/condensation system to recover 74–85% the water in urine, yet suffers from repetitive scaling biofouling while employing hazardous chemicals. In this study, alternative non-sanitary five-stage treatment train for one "astronaut" was integrated through a sophisticated monitoring control system. This so-called...
There is no efficient wastewater treatment solution for removing organic micropollutants (OMPs), which, therefore, are continuously introduced to the Earth's surface waters. This creates a severe risk aquatic ecosystems and human health. In emerging water processes based on ion-exchange membranes (IEM), transport of OMPs through remains unknown. We performed comprehensive investigation OMP single IEM under non-steady-state conditions. For first time, positron annihilation lifetime...
Chemical industries around the world show an increasing awareness of their ecological footprint, including water use. A shift toward alternative sources, such as wastewater streams or surface water, is slowly becoming a well-known concept to reduce intake ground and drinking water. However, change often leads unforeseen challenges (for example, faster breakthrough organic matter growth biofilms) requires review currently used treatment technology. study in various Antwerp companies was...
Film-forming amine products (FFAP) are frequently used as corrosion inhibitors in steam-water systems. To have a better understanding of their behavior the treated system, liquid chromatography coupled to high-resolution mass spectrometry (LC–HRMS) method was developed. This enabled concurrent targeted quantitative analysis film-forming oleyl propylenediamine (OLDA) and nontarget screening (NTS)-based potential degradation FFAP or other organic matter system. The applied samples collected...
