Separation of polyphenolic phytochemical compounds from their mixtures with sugars is necessary to produce an added-value sugar-reduced extract with high biological activity from fruit juice processing industry waste streams. The separation characteristics of a binary mixture of rutin and glucose using a Pellicon-2 regenerated cellulose ultrafiltration membrane with an area of 0.1 m(2) having n...

This study is the first attempt to investigate the effect of total hardness and ionic strength on coagulation performance and the floc characteristics of titanium tetrachloride (TiCl4). Membrane fouling under different total hardness and ionic strength conditions was also evaluated during a coagulation-ultrafiltration (C-UF) hybrid process. Coagulation experiments were performed with two simula...

To recover gold, this work used a novel direct contact membrane distillation (DCMD) reactor with a hybrid electrolytic process. Analytical results demonstrate that permeate flux increased as feed -2 -1 temperature and feed flow rate increased. Permeate flux increased from 2.8 to 17.6 kg m h when -2 -1 temperature increased from 30 to 70 °C, and increased from 9.2 to 19.9 kg m h when the feed fl...

Multi-objective optimization using genetic algorithm (GA) is carried out for the desalination of brackish and sea water using spiral wound or tubular modules. A few sample optimization problems involving two and three objective functions are solved, both for the operation of an existing plant (which is almost trivial), as well as, for the design of new plants (associated with a higher degree of...

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 ...

Modeling mass transport of ions across the polyamide active layer a reverse osmosis (RO) membrane requires comprehensive understanding structure and chemistry. For instance, charge ionization thus salt greatly depend on feedwater pH composition, but these relations are not yet well understood. To address this gap in understanding, one dimensional model is developed that couples all using extend...

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). ...
