Filtering with a whole house filter...?

[Brewgrrrl]

Ah! Thanks! Any tips on tubing/connectors for the whole house filter?

 

[Wade E]

I agree with appleman, you dont need to sterile filter often or at all really for 99% of your wines. 1 and 5 micron will do a very good job and those you can usually get anywhere you buy the whole house filter housing from. Do not use carbon filters on wine unless you want to rid your wine of almost all flavor! As far as hoses go you can get hose barbs either in 1/2" or 3'8", you might have to get an adapter to get down to that hose barb depending on where you go though. I wouldtry and use 1/2' hose though so as not to create more pressure on your pump.

Thanks again! (and, about the carbon filters - I thought so!) I may have to try this over the weekend... bwah-ha-haaaa...

No fair, you cant go get 1 before me!

I just spent some good money with George on some Brew. Until I get a better Brew pot and a March pump I cant do anymore AG's as Im struggling with this crappy pot and lifting it is killing my back, so in the meantime Im going to do a few Brewers Best and one Mini mash Magic Hat that I had Brian here make me up a recipe for. Just oredered that and then in the meantime I can start saving to get my brew sculpture set up better for good. Anything I can do to make it easier on my back. Just got the results from my doc, 2 severly herniated discs!

Ooooh... now I have beer envy! I'm still brewing in the kitchen with a giant pot, and my mash tun/lauter tun are sadly neglected... (sigh...)

I may have to try the house filter just to cheer myself up...

Wade, I'm sorry about your back. I know everyone's got to find what works for them, so this is just offered as my own experience: after playing rugby for 13 years, I had two separate doctors telling me I needed back surgery. Instead, I went to a chiropractor and that really made a big difference (after a few weeks, no more shooting pains and much less morning "ows" - and I still remember the morning I dropped something and was actually able to pick it up without sort of crawling down the wall for support). Then I found myself an inversion table for in between appointments, which has been awesome. The book, "Pain Free" by Pete Egoscue was also really helpful (easy stretches to relieve pressure and realign the body - my chiropractor wanted to know what I was doing to stay in alignment, so it wasn't just my imagination that it was working).

Just my $.02, but whatever you try I really hope that you find some relief. Back pain sucks beyond belief.

Nice to know there are other homebrewers here.

2 days agi I keged my Raspberry wheat. Can't wait till I put it on tap.

 

[Brewgrrrl]

When I survive the holidays, I will celebrate 2010 by brewing a double batch of chocolate stout... maybe separating it in many different batches and doing fruit... vanilla... (sigh...)....

 

[xanxer82]

I just got shipping conformation on my vinibrite filter. Made sure to order an extra set of paper filters.

 

[Tom]

I do a AG Chocolate Oatmeal Stout 10 gal batch ... Hmmm like "Breakfast of Champions"

 

[grapeman]

Oh, if only I was making giant vats of delicious wine that would make such a "not recommended for re-use" filter make sense... (sigh)... Obviously, I need to get some bigger fermenters...

If you want to re-use the filters, the PP and PES filters may be re-used after proper cleaning and drying. They are pricey, but with re-use figured in they wouldn't be that bad. Below is some information on cleaning:

Absolute vs High Efficiency vs Nominal
In practical terms, Absolute means all particulates below a specified size are removed. In quantitative terms, most mfgs employ the standard of &gt;99.98% efficiency. PES cartridges exceed this standard. High Efficiency is typically reserved for filters of &gt;90% efficiency. Nominal filters are typically 60-90% efficient.


What is BETA? Beta is simply another means of expressing efficiency. A filter of 99% efficiency allows 1 particulate out of 100 to pass. The Beta = 100. A filter of 99.98% efficiency lets 2 in 10,000 pass ( or 1 in 5000). Beta = 5000. So Absolute filters have Beta &gt; 5000.</TD></TR></T></T></T></T></T></T></T></T></TABLE>

Cleaning PES cartridges
Do NOT backwash (reverse flow) PES filters
Procedure 1. This procedure does not involve caustic or acid.
a)Forward flow with cold water for 5 minutes to remove product.
b)Forward flow with hot water (175° F) for 5 minutes.
c)Now recirculate with hot water for 15-30 minutes. Leave hot water in unit overnight.
d)Rinse with hot water for 2 minutest the next morning.
f) Air-dry cartridge and store in open to avoid mold growth. You can store the cartridge in the filter housing, but be sure to open the valves so air can penetrate.
Cleaning solutions should be filtered. Flow rate ~ 4 GPM per 10" cartridge.
</TD>
<TD vAlign=top width="58%" colSpan=2 height=177>
If Procedure 1 is not effective, this procedure may be used.
Caustic is dangerous. Wear rubber gloves, boots, safety glasses and apron.


Procedure 2. Hot cautic cleaning
a)Forward flow with cold water for 10 minutes to remove product
b)Forward flow with hot caustic solution (140°-150° F) for 30 minutes. (1% NaOH). This is recirculation but discard the first gallon or so.
c)Forward flow (recirculate) with acid solution for 5 minutes. Any weak acid is suitable including vinegar.
d)Forward flow with cold water for 30 minutes. Do not recirculate in this step. You must be certain that all caustic and acid is removed.
f) Air-dry cartridge and store in open to avoid mold growth. You can store the cartridge in the filter housing, but be sure to open the valves so air can penetrate.


Cleaning solutions should be filtered.
Flow rate should be 4 GPM/10" cartridge for hot caustic. 4-10 GPM/10" cartridge for cold water and acid solution.


Procedure 3. Alternative cleaning procedure using cold caustic:


a)Forward flow with cold water for 10 minutes to remove product
b)Soak overnight--up to 12 hours-- in caustic solution (1% NaOH)
c)Soak in acid solution for one hour (any weak acid including vinegar)
d)Forward flow with cold water for 30 minutes. Do not recirculate. You must be certain to remove all caustic and acid.
f) Air-dry cartridge and store in open to avoid mold growth. You can store the cartridge in the filter housing, but be sure to open the valves so air can penetrate.


Cleaning solutions should be filtered.
Flow rates should be 4-10 GPM/10" cartridge.</TD>

Cleaning PP cartridges


The cleaning procedure for PP cartridges is the same except you can reverse flow through PP cartridges. Be careful not to exceed the maximum pressure for reverse flow.

These are the ones I use for down to 1 micron. I have one rated at .35 microns that is pleated polyester and is about $15 each, but haven't used it yet. The others are cheap enough that if I filter several carboys at a time, it isn't worth trying to clean for me because of time involved versus cost - about $4-5 each.

Here is a membrane filter that fits the same housing (Pentek 3G) as used for the above that filters to .15 microns- but it is $100 each, but could be cleaned.

Here is another source of Pleated Polypropylene filters and also PES filters(membrane) that fit standard DOE housings (double open ended).

Do you need to run K-Meta solution through the new sediment filter before filtering? Or can you just sanitize the housing and hoses and let it rip?

 

[grapeman]

You should at least run water through it to clean the filter of particles- k-meta solution wouldn't hurt. Just let the vacuum suck out all it can and maybe even tip the filter upside down if it doesn't have a air release.

 

[vscottcolorado]

I really could not wait to try my new filter so I filtered a WV Vieux Chateau du Roi which was made with 10 lbs Lodi Cab Skins from this fall. I usually don't filter reds but I had to try out this new set up. When I do filter whites, I rent the Buon Vino Mini Jet Filter Wine filter from the local shop, $4, Filter pads $8. The filter housing and Filter cost me $14 plus shipping. By the way I used a 5 micron filter on this red.

 

[Tom]

And the results are??

 

[vscottcolorado]

This red had been bulk aging since the end of December. Even after racking twice a ton of lees in the bottom. I think the filter did incredible! The proof will be in the bottle in the next 3-6 months. We tasted this at our club meeting last Sunday, though young you could really see the differance compared to another Chateau du Roi that had been bottled for almost a year. I am a believer in the addition of skins to these smaller kits.

 

[Wade E]

Glad to hear about the success of the filter and now you know why I like the grape skin kits, they add a much needed strength and complexity that the big reds just need.

 

[vscottcolorado]

I still have 60lbs of Shriaz skins and 20 lbs of cab skins. Any idea on shelf life in the freezer on crushed skins?

 

[Wade E]

I would imagine indefinitely or until it gets freezer dried.

 

[Comet in TX]

Can the wise-ones-who-trod-this-path-before-me advise on whether you filter using 5 microns first, then 1 micron, or is the 5 only necessary if you haven't really been minding your lees?

I'm very excited - I have my vacuum pump now! Tomorrow I have to buy 1 bung and then I will be transferring, filtering, degassing and bottling 4 carboys this weekend!

Maybe y'all better get ready for a flurry of frantic posts....

Thanks for all the advice!
Lara

 

[grapeman]

The 5 micron will get the large crud out and keep the finer filter going longer. Good luck with your setup and filtering.
