Recovery of ammonia (NH3) from residual waters offers various reuse opportunities, such as the production fertilisers and generation electricity heat. However, simultaneous evaporation water (H2O) during NH3 stripping under vacuum results in diluted recovered gas with high H2O contents. Whereas porous gas-permeable membranes are already used for stripping, use non-porous silica-based pervaporat...

The gas-liquid membrane contactor (GLMC) is a promising alternative gas absorption/desorption configuration for effective carbon dioxide (CO2 ) capture. The physicochemical properties of membranes may synergistically affect GLMC performances, especially during the long-term operations. In this work, commercial polypropylene (PP) and polyvinylidene fluoride (PVDF) hollow fiber (HF) membranes wer...

A membrane-based enthalpy exchanger is a device used for heat and humidity recovery in ventilated buildings. The energy-saving potential of such dependent on the parameters responsible moisture recovery. trend toward composite membranes, which are custom produced, their can be adjusted given application; therefore, diffusion sorption characteristics membranes unknown. In order to obtain values ...

purpose : to evaluate the correlation between inner segment/outer segment (is/os) line and external limiting membrane (elm) layer integrity at foveal center and visual outcome and to investigate the prognostic factors in optical coherence tomography (oct) that related to final visual acuity (va) and recovery time in acute central serous chorioretinopathy (csc) methods : we prospectively studied...

Polymer-based membranes have advanced or novel functions in the various membrane separation processes for liquid and gaseous mixtures, such as gas separation, pervaporation (PV), reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), other critical applications of water purification, solvent concentration, recovery [...]
