Fouling - Ultrafiltration Lemon Juice
Fouling - Ultrafiltration Lemon Juice
(OP)
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 this kind of fouling?
Thanks in advance...

RE: Fouling - Ultrafiltration Lemon Juice
the problem with citrujuice is pectin and other biopolymeres, so you have to use a big amount of enzymes. unfortunately the citrus oil will destroy your membran anyway after a longer use.
i don't know any reference.

RE: Fouling - Ultrafiltration Lemon Juice
Apfelsaft is absolutely correct. The juice must be de-oiled, typically to less that 1 ppm. Next a pectinesterase enzyme is used to fully depectinize the juice. Also, dependent upon the membrane configuration the pulp and soluable solids content may a role in fouling as well.
There are several things that should be considered.
Hope this helps.

I don't know. but I imagine there is some chemical compound in lemon juice responsible for this problem.

What type and configuration of membrane are you using?

Pilot Scale.....but it is the same process used in Citrus Industry in Brazil and US. This kind of process has been used in citrus companies as routine process. My target is to answear this special question about lemom problem....I already have confirmed this drop in flux performance when Lemon Juice was used as Feed. Lemon is the challenge.
