the growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (md) process, as a promising separation technology, has recently gained more attention. the md process is a non-isothermal membrane-based separati...

A two-dimensional numerical model for a direct contact membrane distillation (DCMD) module, mostly used desalination and wastewater treatment, has been created. This to explore the sensitivity of simulated transmembrane flux water vapour modelled module some commonly-used assumptions simplifications related mass transport in membrane, namely: equimolar diffusion; Knudsen diffusion-free transpor...

Membrane distillation (MD) was applied for the concentration of a range of dairy streams, such as whole milk, skim milk and whey. MD of a pure lactose solution was also investigated. Direct contact MD (DCMD) mode experiments were carried out in continuous concentration mode, keeping the warm feed/retentate and cold permeate stream temperatures at 54 °C and 5 °C respectively. Performance in term...

Visually guided collision avoidance is critical for the survival of many animals. The execution of successful collision-avoidance behaviors requires accurate processing of approaching threats by the visual system and signaling of threat characteristics to motor circuits to execute appropriate motor programs in a timely manner. Consequently, visually guided collision avoidance offers an excellen...

A rigorous and high-fidelity two-dimensional numerical model for a direct contact membrane distillation (DCMD) module has been developed. The developed incorporates all the key physics governing transport phenomena taking place within (MD) module. spatial variation of physical properties fluids flowing in channels with temperature captured. used to investigate sensitivity performance indicators...

Penggunaan lithium dalam pembuatan baterai meningkat secara signifikan beberapa tahun terakhir. Karena peningkatan kebutuhan lithium, maka diperlukan sumber litium yang dapat di eksploitasi. Target dari penelitian ini adalah untuk memekatkan konsentrasi sebelum dilakukan proses pemisahan lainnya. Perangkat DCMD menggunakan perbedaan tekanan uap dikedua sisi membran sebagai driving force. Laruta...

Melissa officinalis (Lamiaceae) é reconhecida por diferentes propriedades fitoterápicas e fisiológico-funcionais. O objetivo do estudo foi avaliar o efeito dos extratos dessa espécie sobre parâmetros de crescimento, histologia hepática exames bioquímicos ratos wistar alimentados com dieta cafeteria. Foram utilizados 32 animais, divididos em quatro grupos (n=8): C – grupo controle, ração comerci...
