Hi brewers,
I have been thinking about the filtering issue for quite a long time. I would like to avoid plate filters and diatomite filters due to several reasons. As it seems more and more brewers are using systems like the PALL Supradisc II or other systems like the one from Filtrox which are modules you can backwash several times:
I contacted PALL and an agent came for a visit to present the Supradisc II. Of course they try to convince you that their system is better than the one from Filtrox. I guess it is more or less the same. But the backwashing with the PALL systems seems to be more safe to me. However, the modules cost around 265 USD for the 16" (5 m2) and 135 USD for the 12" (1.8 m2). As I can remeber Filtrox is a bit less expensive here.
He told me with the 16" I will definitely be able to filter around 120 hl. This would mean around 22 USD for filtering 1000 liter. Compared with other costs 22 USD seem ok to me.
Now what I find a bit insane the price for the metal housing of the filter. They want 6'000 USD. I could get a brand new CCT for this. The price from a Filtrox company was 1'000 USD for a 10" just for comparison.
Do you know brewers who are using the PALL system? If yes, are they happy? What do they say? What are their experience?
Has anyone ever had bad experience with backwashing Filtrox modules?
The agent said they recommend to just wash the filter with hot water or steam and keep it in a CO2 atmosphere in the housing. I somehow think this is a bit risky. I would definitely put peroxyacid solution in there or another desinfectant.
What do others do?
I wil usually filter 10 hl from a 24 hl tank into a 10 hl bright tank. Is a 12" enough for this? The agent did not really know and (of course) proposed the bigger one (16"). Are there brewers who are using a 12" for 10 hl without blocking?
Does anyone know if it is possible to buy a suitable housing from another company for a more reasonable price?
Best regards, Daniel
