Title: water filtration
Post by: rje66 on December 29, 2014, 06:41:12 PM
Any good recommendation for types of filtration from kitchen sink tap..either install under sink before it hits the taps or fit to tap when filling FV.
Ideally a supplier in Dublin.

i suppose that depends on what you're trying to filter out.

@rje an RO system will give you a pure water source, excellent for treating to achieve a beer specific profile. Most of them have a very slow output so you can't simply pour 30litres and start brewing. You can buy pumped systems that claim a v large throughput(vyair.com). Typically they tap into the cold supply to the sink tap and have their own RO tap mounted beside the main sink tap

Ritchie: I just use a Proplumb Sediment/Charcoal filter on my Seabury water.

Get them in Woodies/BnQ

Have I not shown you my set up?

You mean one of these inline? http://www.woodiesdiy.com/Mobile/Product/water-filter-kit/13255/6.0.8.3#ctl00_ctl00__nestedContent__mainpageContent_ProductFamilyDetailsView1_liProductDetails

How long does it take to filter 30L and what treatment do you need after?

The RO system looked a bit expensive, if the fun prevention officer got wind of it  I could be in the dog house :'(.
Will I didn't get a look when I was over but saw in in a photo you had posted, its just a hook up to the tap type thingy??

Possible home brew filter pre keg as well ? ???

With RO, watch out for the volume of waste water with water meters on the horizon.
A carbon filter may suit...

I returned my RO system because they quoted 4 parts water for 1 part waste and it turned out closer to 1 part water for 4 parts waste.
Also, because it strips everything from the water it's bad for you.

Quote from: WHOThe final report, published as an internal working document (WHO 1980), concluded that "not only does completely demineralised water have unsatisfactory organoleptic properities, but it also has a definite adverse influence on the animal and human organism."

And it's a waste of time if your water already is very low in mineral  content - as is the case, for example, in  Cork city.

Also, consider 1/2 Campden tablet per 25l overnight to clear out ine/ide (whichever)

I have a RO system fitted in my kitchen which I bought from Brenmurph. It has a separate tap that I drilled a hole in the metal sink and fitted and has a 3 Gallon collection tank to slowly collect the water as it filters through 3 types of filter. It does waste water as has being pointed out and it strips everything leaving just H2O. It tastes much better than what comes from the tap. To brew with it is a bit awkward as it takes a while to collect 30 litres because the holding tank only builds up slowly and maxs out around 12 litres a time. But if you are brewing with it you have a blank slate to add back the exact minerals you want for the beer you are brewing. For regular brewing the household one is not really practicable :).

As Brian says the output from the household one is very slow.  I don't brew very often so it does me. I fill 5Litre containers in advance so I need to plan at least 2 days because of the slow fill form the RO tap, however the water can be stored for long periods. Ive stored it for over 6 months in 5L bottles and it was still perfect, and it makes an excellent blank slate fro creating your desired water profile

Just remember that it not only strips salts but all minerals so you should always supplement yeast propagation by adding yeast food, including zinc and magnesium as distinct from adding spent yeast, particularly if you intend to crop the yeast
