The robustness of reverse osmosis (RO) against polar organic micropollutants (MPs) was investigated in pilot-scale drinking water treatment. Experiments were carried hypoxic conditions to treat a raw anaerobic riverbank filtrate spiked with mixture thirty model compounds. chemicals selected from scientific literature data based on their relevance for the quality freshwater systems, RO permeate and water. MPs passage influence flux evaluated typical low-pressure membrane quantified by liquid...
The treatment of textile dye solution is considered one the most challenging wastewater treatments, representing a major concern for ecosystem. This study investigates efficiency direct contact membrane distillation (DCMD) synthetic in lab test cells. effect feed temperature and flow rate on MD fouling were investigated at water temperatures 40 °C, 60 80 °C rates 15 L/h, 30 L/h 45 L/h. Results show that (i) negligible was observed (ii) increase impacted process performance, leading to severe...
Reverse Osmosis (RO) is a membrane-based technology for water desalination. Of paramount importance the understanding of ion selectivity in mixtures salts, i.e., to what extent membrane retains one more than another multicomponent salt solution. We apply continuum transport theory describe large set data RO membranes treating brackish groundwater with 10 different monovalent and divalent ions. The model based on Donnan steric partitioning pore extended include ions multiple charge states,...
Naturally present indigenous fresh water viruses are able to accurately monitor virus rejection of intact and damaged RO membranes, with high sensitivity similar performance as spiked bacteriophage MS2.
The potential of membrane scaling control by a real-time optimization algorithm was investigated. effect antiscalant dosing evaluated from the induction time measured in glass batch-reactors, and operational performance lab-scale reverse osmosis (RO) unit two pilot-scale RO units. Step changes demonstrated that accumulation is 'paused' during periods when optimum dose applied. This paramount for application dynamic strategy may briefly underdose, while searching dose. It found underdose...
Affordable thin-film composite (TFC) membranes are a potential alternative to more expensive ion exchange in saltwater electrolyzers used for hydrogen gas production. We solution-friction transport model study how the induced gradient controls across polyamide (PA) active layer and support layers of TFC during electrolysis. The set parameters was simplified by assigning same size-related partition friction coefficients all salt ions through membrane layer. fit experimental data from...
Ensuring the biological stability of drinking water is essential for modern supply. To understand and manage stability, it critical that bacterial growth in can be measured. Nowadays, advance treatment technologies, such as reverse osmosis (RO), are increasingly applied purification where produced characterized by low levels nutrients cell counts. The challenge is, therefore, how to measure potential (BGP) ultra-pure using available methods which were originally developed conventionally...
The role of phosphate and humic substances (HS) in preventing calcium carbonate scaling their impact on antiscalant dose was investigated for a reverse osmosis (RO) system treating anaerobic groundwater (GW) (containing 2.1 mg/L orthophosphate 6–8 HS). Experiments were conducted with the RO unit (treating GW), once-through lab-scale (operating artificial feedwater). Additionally, (batch) induction time (IT) measurements performed with, i) real concentrate, ii) concentrates presence absence...
