Hi.. I am studying a process of fermentation of sugar cane juice. I have been facing a hard barrier to find out a paper or literature about yeast gowth in this kind of process. My real target is to understand the production ratio to calculate Kg dry yeast produced per liter de alcohol in a...

Hi.. I was using Kamoran HJ in industrial scale to control infection in fermentation to produce Ethanol. The supplier of Kamoran HJ (Monensin, Sodium) is not able to support us in a ideal way (costs, logistics, etc) Please, could you people help me to find other supplier around the world...

Hi..everybody!! I am very interested to know more about Biomass possibilities. I am focusing what is the real truth about this products. Do you know some good reference technical and economical approach??

Hi.. I have worked some cycles using a pilot plant with spiral wound membranes to concentrate fruit juices. I have recorded the driven pressure (range 500-600 psi). I would like to know specific information about transmembrane pressure!! a) What exactly is the Transmembrane pressure...

Hi...people.. I am facing a very interisting career situation. I am 32 years old and I have worked in industrial (chemical engineering) area for 10 years. I really like to manager technical teams and R&D Project but I am not a kind of guy who likes to be involved in main calculations of...

Usually regular RO spiral element applies a range of feed spacers...I am testing a ro membrane to concentrate fruit juice. I am really confuse about feed spacers...targeting a solution as juice with high content of soluble solids, what is the ideal choice? As bigger as better? Comparing an...

Hi.. My question is about RO and Fruit Juice.. Feed: 8 to 12ºBrix Concentrate Target: 15 to 20ºBrix Permeate: 0º Brix (No sugar--:)ok) 2 Membrane Supplier. Pilot Plant - 2 (4 x 40") elements * Feed from industrial pipe, it is not a lab experiment. I have ran 6 experiments/suplier...

Hi...I am preparing information to write a paper about Reverse Osmosis - Juice Concentration. I have been face basic questions, but wich one must be considered during this work. I have had questions about right technical terms for this process. For example: a) Flux --- Can I use to describe...

I use to run CIP using Caustic solution 1.5%, I am intending to decrease this concentration...maybe 0.5 to 1%, I suppose will be enough to clean pipes (concentrate orange juice pipes). Caustic solution temperature 60ºC..is there some kind of limitation about temperature...I am thinking about...

I need to calculate an project to storage bulk orange cells. In orange juice industry...usually : Orange Juice+cells >>>Turbo Filters>>>Juice Cells I do have viscosity and density of this wet cells....somebody can give me an idea about how to estimate this viscosity...

Hi... I am starting to work using R.O. Spiral membranes, I would like to understand when manufacturer provide information as 80 mil, 43 mil...what is exactly part of the membrane use to have this kind of measurement? If I am intending to calculate filtration area have I to consider this...

Hi... I am starting a project pursuing to develop a model using ASPEN PLUS. I intend to find experimental references and after this step to start this prediction project. I have had interested mainly in Pervaporation, but in a second stage of this work I can try to do something targeting...

Hi..I am learning about diffusion in membrane processes. Please, could you help me to find a paper with this kind of calculation. So I can calculate and check with paper results. It will be very useful as an training. Feed Liquid>>>Membrane>>>>Permeate Araujo

Hi..It´s my first message... I am starting PhD program. The main target is to develop a pervaporation prediction software to evaluate aroma recoveries from Fruit Juice. I am intending to start with key aroma compounds. Please, I would like to know if you know some reference about...

Hi...I am pursuing some paper or reference about a special kind of Fouling. I have perceived some decreasing in flux during my experiments with citrus juices. When I run UF process with Lemon Juice there is a strong drop on flux. I am using Polisulfone Membranes. Do you know some reference about...
