Development of a mathematical model for apple juice compounds rejection in a spiral-wound reverse osmosis process

摘要: Abstract The use of Reverse Osmosis (RO) membrane processes for the clarification and concentration apple juice is proposed as an alternative to conventional technique, which based on evaporation freezing. Several models have been published RO process relying different assumptions that predict permeate flux aroma compounds rejections aqueous solutions juice. solution-diffusion model (Lumped model) has applied previous models. main instrument this study gPROMS software develop a new distributed steady state will relax number earlier assumptions. validated with observational data filtration derived from literature by analysing performance rejection at concentrations, temperatures pressures laboratory scale spiral-wound module. Simulated results corroborate experimental predictions.
