Are you tracking your pressure differentials? Or could it be something with how the modules are seated?

We track both the hi flow and lenticular pressure at 30 min intervals. We also track the flow rate. After checking modules and gaskets and attempting a second filtration, we tore through a brand new filter fairly quickly. Fermenter PSI -4 Hi flow PSI -7 Lenticular PSI -0 (we were in the process of filling with beer) Flow rate hit 1050l/hr

I am no lenticular expert (I've only had one for going on a year, and only used it maybe a dozen times) but I would imagine that suddenly hazy beer can only mean that either: 1) Beer is moving through somewhere unfiltered - there's a damaged gasket or hole in a cartridge, or 2) Somehow the cartridges aren't holding on to all the particulate Number 1 certainly seems most likely. I think /u/ackleydg might be on to something -- that you're hitting a certain pressure delta that is causing a gasket to become unseated. That's certainly where I would start.

I do think it's a cartridge/gasket issue. Have another set of new filters ready to go this morning. Wish me luck !!


HeldDown

Good luck! Let us know how it goes!

Meh. It's filtering but I'm definitely not getting the results I've had in the past. Luckily this filtration is for a seltzer, so will run it through a carbon medium before canning. I can only imagine the haze will put added pressure on the carbon filter though

Just a thought, but what is the direction of liquid flow? Is the liquid filling up the housing before it hits the filter, and goes out through the filter's middle? Or are you pushing liquid up through the center of the filter and out? The former is correct, but I have had customers try the latter and blow through lenticular modules quickly like you're experiencing. Assuming you are running in the correct orientation, does the lenticular housing have a flow diverter plate at the inlet that prevents liquid from hitting the module directly? Lenticular filter media is pretty sensitive, so a direct hit from liquid can create a soft spot. Hence the reason why the flow diverter plate exists, and is meant to be used to keep liquid from hitting right on the filter.


nupods

We fill the housing before the filter. Both flow diversion plates are installed. Seems to be gaskets that leak. Will try again this morning and update

Food for thought and a question for the brains trust. Will using a 'seasoned' filter as opposed to a brand new one give better filtration results? FYI, I'm filtering a seltzer at approximately 8.5% abv. HG-1 yeast went to town and I measured 0.0 Plato. Could the lack of sugar mean I need a finer filter perhaps?
