Can 0.025 Micron Cartridge remove Ethanol ?

[Fxaddicted]

i recently bought Water Filtration system from a local company . this system have 6 stages . i noticed one of the stages using 0.025 Micron Cartridge .

my question is can this 0.025 Micron remove Ethanol ? at what size Micron Cartridge can remove Ethanol giving that alcohol molecules are 3x the size of water

i was thinking to use this system with 20% ABV spirits and also Hard seltzer

here is the full specification of this system and it seems all fine except for Fourth stage

First stage (cotton filter):
It consists of a polypropylene cotton candle that filters down to 5 microns and removes solid impurities such as sand, mud and algae.

Second stage (carbon steel filter):
Made of carbon steel, its function is to remove dissolved gases and treat water from undesirable substances such as chlorine, taste, odor and color, in addition to the smallest impurities down to 1 micron.

The third stage (salt filter):
Through which it is possible to control the percentage of salts taken from the source.

Fourth stage (ultrafiltration UF membrane):
Works not to enter bacteria and heavy metals if the salt stop is opened. Its pore size is 0.025 microns and allows the passage of minerals and salts that are beneficial to the body.
((It is excellent for people who want to retain minerals such as calcium, magnesium and salts in their water)).

Fifth stage (UV):
An electric filter concentrates ultraviolet rays on the water to kill viruses

Sixth stage (post carbon filter):
A carbon filter made of coconut shells removes any taste or smell before the water enters the tank.

I wouldn't run anything containing ethanol through it.

I make neutral with a reflux still. I filter water using an RO unit (reverse osmosis). I dilute the neutral with RO water to 80 proof. I blend whatever I want to make a drink, carbonate and pour on ice.

thanks . yeah but sometimes i need such system for Hard seltzer that required no distillation . if this 0.025 Micron doesn't remove ethanol then it sounds like a great Idea

Depending on what these filters are made with rule "I" may be relevant.

Definitely Cob .
I know the triple water system in my house is all plastic housings , rubber seals and O-rings and the cartridges all contain plastic somewhere .

Might be acceptable for low alcohol like beer and wine but no way suitable for distilled spirits .

But then , these hard Seltzer drinks that I’ve heard of are only beer strength .
That being the case , filtering the finished product at @5% abv or what ever it is should not pose too much of a risk .

At 20% abv , maybe I’d be cautious personally .

Your 0.025um is 25 nanometres.
A water molecule is 0.28nm
An ethanol molecule is 0.44nm

You need another two zeros after the decimal point.
The product your possibly looking for is called an Molecular sieve.
Im not sure what your trying to do though, if you want to remove alcohol, distil it?
Figjam, headache free beer! Run it to just the start of hearts n stop...
Ok now someone chime in with a link of somewhere doing it already so i can stop feeling clever

He's trying to ensure the filter WON'T remove the ethanol. He wants to filter out all undesirables but he wanted to make sure the filter wasn't fine enough to remove the ethanol.

Sounds like his setup will be fine as long as he keeps the abv low.

If you need to up the abv, I would recommend making the seltzer as you normally do, then raise the abv with a good clean neutral post filtering

exactly . that's what i want and yes i agree this will be great for hard seltzer to get clean product before flavoring

Ethanol is a funny animal. Yes, the molecular weight number says it’s 3x the size of a water molecule but it’s permeability and rejection through membrane filtration is far from absolute.
When it comes to the production of hard seltzer beverages we are typically utilizing some type of reverse osmosis membrane but operating at very high pressures (upwards of 700 psi) to obtain significant passage of ethanol while exploiting the retention of the membrane to capture some of the small organic molecules that are quantified as off odors/flavors, in addition to being necessary to obtain suitable yields. That would be a lot to expect of a household water filtration system.
At fermentation level ABV’s there are no concerns from the FDA or membrane manufacturers. For them, ethanol is considered an organic solvent. At the concentrations and temperatures we run at, there are no concerns. While we might be concerned about polymer component chemicals showing up in a finished product, if such a thing were an issue it would also quickly degrade membrane surfaces and destroy their integrity. With such a closely defined molecular membrane structure any such damage would simply ruin them. Membrane filtration technology is used extensively for the production of hard seltzer and if membranes didn’t hold up to the rigors of production they wouldn’t be used. A large scale producer with multiple systems is easily looking at over $1,000,000 worth of membranes alone to fill them all.
After all that, can you use membranes or a sub-micron filter to remove ethanol?, was the original question. Yes, you can, but at a level waaaaay finer than described. RO, and ethanol for that matter, are well beyond a particle size level and these things also function within certain principles of ionic charges, and they can do a pretty decent job of holding back undesirable components. Think of it almost like a cold strip run that puts out a low wine in the 15% range and pretty well neutral already. Take that, and give it a simple distillation and it makes some pretty decent vodka without a much effort (like, say, fermentation, multiple distillations, and all that jazz). Not quite perfectly neutral but not unpleasantly so. I’ve done so on several occasions as we have had test material come through our facility and we had to make hundreds of liters to reach an end data point that only requires a small sample for analysis.
For the hobbyist, forget it. But, if you happen to be near my neck of the woods, I’d be happy to set anyone up when we get some of this in. Better than dumping it down the drain.

Thanks a lot mate . what a great answer
