Pilot tests were performed with a process combination of electrodialysis and ozonation for the removal of micropollutants and the concentration of nutrients in urine. In continuous and batch experiments, maximum concentration factors up to 3.5 and 4.1 were obtained, respectively. The desalination capacity did not decrease significantly during continuous operation periods of several weeks. Membr...

Endosulfan (ES) is a micropollutant found in reverse osmosis concentrates from water reuse applications. Electrodialysis (ED) can remove and recover charged solutes from such concentrates. While polar compounds cannot normally be removed, their fate in ED is important as they can contribute to membrane fouling/poisoning and be released during cleaning. High adsorption of ES to ED membranes was ...

In lactic acid fermentation by Lactobacillus delbrueckii, the produced lactic acid affected the lactic acid productivity. Therefore, for the purpose of alleviating this inhibitory effect, an electrodialysis fermentation method which can continuously remove produced lactic acid from the fermentation broth was applied to this fermentation process. As a result, the continuation of fermentation act...

The current maldistribution along the flow path of electrodialysis (ED) units is a well-known phenomenon. However, it has been poorly quantified via experimental tests so far. This work aimed at measuring distribution in an ED stack with 40 cm length, provided four-segment electrodes. current-voltage curve (CVC) each segment was recorded under several operating conditions inlet concentrations a...

Rare earth elements (REEs) including Scandium (Sc) are critical raw materials which greatly needed in the advancement of many modern technologies. Due to problems associated with primary extraction mining ores, procurement Sc and REEs from secondary resources currently explored adopting principle sustainability circular economy. Herein, for first time, Electrodialysis (ED) technology based on e...

Wastewater contains resources, which can be recovered for secondary use if treated properly. Besides research in zero liquid discharge solutions, the aim of study was a simultaneous recovery products from wastewater treatment plant’s dewatering liquor. To specific, we investigated struvite and irrigation water using electrodialysis (ED) laboratory experiments. Two were obtained ED—concentrate d...

The efficiency improvement of wastewater recycling has been prioritized by ‘Goal 6’ the United Nations Sustainable Development initiative. A methodology is developed to synchronously profile multiple water-quality indices a electrodialysis (ED) process. non-linear multifactorial screener exclusively synthesized assembling proper R-based statistical freeware routines. In sync with current trends...

The transport selectivity of different cations through cation exchange membranes (CEMs) could be estimated with the partitioning factor (Kji) and mobility ratio in membrane (uim/ujm), which turn can related to corresponding conductivity dimensional swelling data [Journal Membrane Science, 2020, 597, 117645]. This method has been validated two hydrocarbon polymer-based CEMs, obtained K+/Na+ equa...

Complexities associated with dissolved organic matter (DOM) isolation from seawater have hampered compositional characterization of this key component of global carbon and nutrient cycles. DOM isolation efficiency by electrodialysis (ED) from saltcontaining waters was optimized and evaluated on samples including coastal ocean seawater, open ocean seawater, artificial seawater from axenic cultur...

This project aimed at producing a concentrated nitrogen fertilizer from liquid swine manure using electrodialysis (ED) and reverse osmosis (RO), as a mean to help resolve the excess nutrient problem faced by many swine producers, and offer an alternative to chemical nitrogen fertilizer production. Different types of ED membranes were evaluated based on the NH4+ transfer rate, current efficiency...
