Separation of Sugar from Molasses by Ultrafiltration and Nanofiltration
Molasses, the main material of this project was diluted and processed, according to the type of the used ultra and nano membranes (UF10kDa, UF5kDa, N30F). Permeate flux was determined at different times for membranes and steady time was registered. By changing transmembrane pressure, permeate flux, which is dependent on the pressure, was registered. Final permeate flux was registered in each tr...
متن کاملEffects of ionized sodium concentrations on ultrafiltration rate in peritoneal dialysis using lactate and lactate/bicarbonate solutions.
OBJECTIVE To investigate the possible effects of different concentrations of ionized sodium (NaI) on peritoneal ultrafiltration (UF) rate using lactate (Lac) and lactate/bicarbonate (Lac/Bic) dialysis solutions. DESIGN Two random consecutive (after an interval of 48 hours) peritoneal equilibration tests (PETs) were performed in 13 patients (4 males and 9 females) on regular continuous ambulat...
متن کاملNitrate removal from aqueous solutions by γ-Al2O3 ultrafiltration membranes
In the framework of understanding the transport mechanism that governs the filtration of NO3- solution through a γ-Al2O3 membrane with a nominal pore size of 5 nm at low ultrafiltration, a series of various types of nitrate solutions and operating conditions were investigated. The effect of filtration parameters such as pH, applied pressure and NO3- concentration on the selectivity and permeabi...
متن کاملUltrafiltration efficiency during automated peritoneal dialysis using glucose-based solutions.
The ultrafiltration (UF) efficiency of peritoneal dialysis (PD) solutions, defined as the net UF divided by the amount of carbohydrate absorbed per dwell, has been shown to be higher during long dwells with 7.5% icodextrin solution (Extraneal: Baxter Healthcare Corporation, Deerfield, IL, U.S.A.) than during those with glucose-based solution (2.5% and 4.25% Dianeal: Baxter Healthcare Corporatio...
متن کاملTarget weight achievement and ultrafiltration rate thresholds: potential patient implications
BACKGROUND Higher ultrafiltration (UF) rates and extracellular hypo- and hypervolemia are associated with adverse outcomes among maintenance hemodialysis patients. The Centers for Medicare and Medicaid Services recently considered UF rate and target weight achievement measures for ESRD Quality Incentive Program inclusion. The dual measures were intended to promote balance between too aggressive...
