Global climate change and variability have a negative impact on a water supply and quality in remote areas by reducing water availability and contaminant dilution. This will continue to be exacerbated by limited and inadequate water supply, insufficient water treatment and low infrastructure. Thus, an economic desalination system with a small scale and footprint for such regions is strongly dem...

Filtration under an ultrasonic field is a technique that is gaining importance in the wastewater treatment research field, not only due to its ability as a cleaning mechanism, but also as a filtration intensifier. The main objective of this research was the study of the influence of ultrasonic waves on the filtration of the oilfield wastewater (known as produced water) in order to increase the ...

The consumption of supplements based on dairy or plant proteins may be associated with bioactive potential, including angiotensin-1-converting enzyme inhibitory (ACE-1i) activity, which is linked with blood pressure reduction in vivo. To gain insight into this proposed mechanism, the ACE-1i potential of protein-based supplements, including a selection of dairy (n = 10) and plant (n = 5) protein...

Membrane-based pervaporation (PV) has attracted much attention in the dehydration of organic solvents. Permeate pressure and feed flow rate are two important parameters, which affect membrane performance in pervaporation. The effects of these two parameters on the performance of a commercial poly (vinyl alcohol) membrane in the dehydration of benzene have been investigated in this work. The exp...

The purpose of this research was to studythe ability whey protein concentrates (WPC) and permeate produced with ultrafiltration cheese rehydrate. products studied were concentrate witha PDM percentage 80% (WPC-80), permeate, both under the conditions PJSC Dairy “Voronezhsky”.WPC-80 dissolution processes using microscopy. Water-impermeable hydrophobic layers formed at boundary, preventing water ...

Chemical characterization of scaling and removal processes was performed in real time via Raman spectroscopy a bench-scale reverse osmosis (RO) system. A custom RO cross-flow cell integrated with microscope objective, allowing for analysis localized membrane scale removal. Permeate flux also measured to provide real-time metric comparison. commercial flat sheet, thin-film composite (TFC RO) sca...

One way to overcome the scarcity of clean water through sustainable approach is by utilizing a solar distillation system. This easy-to-use technology adopting tubular distillation. The three main components, which are most essential for producing amount permeate, collector, and heat exchanger (HE). study aims determine performance device equipped with HE using parabolic trough collector (PTC). ...

Membrane biofilm development was evaluated to improve psychrophilic (15°C) anaerobic membrane bioreactor (AnMBR) treatment of domestic wastewater. An AnMBR containing three replicate submerged membrane housings with separate permeate collection was operated at three levels of membrane fouling by independently controlling biogas sparging for each membrane unit. High membrane fouling significantl...

This paper reports on the performance fluctuations during the operation of a batteryless hybrid ultrafiltration--nanofiltration/reverse osmosis (UF-NF/RO) membrane desalination system powered by photovoltaics treating brackish groundwater in outback Australia. The renewable energy powered membrane (RE-membrane) system is designed to supply clean drinking water to a remote community of about 50 ...
