Permeate Flux Model Of Cross-flux For Micellar-enhanced Ultrafiltration In Stable State

Micellar-enhanced ultrafiltration (MEUF) is a new technology for the treatment of wastewater, which makes use of the properties of surfactant micellization and solubilisation and absorption of micellar, and etc, to realize the separation by ultrafiltration.The rate for metal and organic solutes removal is very high. So a phenomenologica mathematical model has been proposed for the batch MEUF process. But the membrane pollution is too serious to use the Hagen-Poiseuille model. And the resistance due to fouling and membrane is very difficult to measure,so the common ultrafiltration (UF) model is unfit to use.It's based on the theory of conservation of mass to set up the single membrane tube permeate flux model of cross-flux for micellar-enhanced inside in ultrafiltration in steady state and permeate flux model of cross-flux for micellar-enhanced outside in ultrafiltration in steady state.Then based on the theory of conservation of energy, we correct the va to va1, and calculate the va1 to set up the many membrane tubes permeat flux model of cross-flux for micellar-enhanced ultrafiltration in steady state, make the modle peferct. And we set up the modle of temperature and permeation flux to quantitatively analyse how the temperature effect the permeation flux by the modle of temperature and surfactant.At the end we chose UEIP503 hollow fiber inside out ultra filtration membrane (Tianjin motian membrane eng.&tech. -co., LTD) and UEOS503 hollow fiber outside in ultra filtration membrane (Tianjin motian membrane eng.&tech. -co., LTD) to do ultra filtration experiment and the result has validated the validity of the model and analyzed internal connecting links-relationship between permeate flux and several parameters such as permeate fluid density, filter cake and etc. It will be a powerful theory for further study of MEUF.
