Carbon filtration

[Frisp]

As part of the planning for my brewery build Im running a water supply straight to my HLT. Will feeding it through a carbon filter de-chlorinate it ?
or will i juts have to bung a campden tablet in each time I fill my HLT?

we just use a campden and all the other chemicals our water profile needs

But do you need to use the Campden after a carbon filter? I'm quite interested in this as I'm planning on doing the same thing and putting a carbon filter in.

done a little reading and it seems to suggest that it will. But my logic tells me that if its such an easy permanent fix . Why havnt AG brewers been building a Carbon filter into their builds?

Ill sit back and see what the Gods of Grain have to say...

Maintainance of the filter? How will you know when it's not working anymore without testing for chlorine?

A CT (if you really think you need it) is much easier.

I've always used a carbon filter (Actually a composite carbon / Resin Filter) for my water as I had it for my tropical fish. . . . It does the job very effectively. As mine is designed for tropical fish it is a 10" filter and will deal with 2000 Gallons of water at 3ppm chloramine or 20,000Gallons at 3pp Chlorine . . . . So quite a long time considering I have around 0.15ppm residual chlorine (allegedly) . . . I just change the carts on a bi annual basis.

The benefit of using a carbon filter is that you can be reasonably sure the chlorine / chloramine is removed . . .but that you have not overdosed the sulphite . . . a well known author has made comments about how risky it is using an overdose of sulphite . . . plus it is completely unnecessary (In his opinion) as most TCP flavours are related to infections . . . which could be true. However, It is a simple precaution, and even using 1CT in 30L of liquor, which is considerably over dosing in my case (1/2 a CT in 17UK Gallons will deal with 3ppm chlorine), does not cause a sulphurous nose (some brewers yeasts can metabolise sulphite to hydrogen sulphide). Indeed as I have mentioned on more than one occasion the excess sulphite acts as a reductone preventing oxidation . . . especially in a mash.

Aleman. can you point me to a make and model...

This is what I use generally, where I used to use a Brita filter jug.

CAn't remember the name of my supplier . . . which probably means I will need to dig out the paperwork and buy another set of carts

In the meantime this is the sort of thing I was taking about Although they don't mention Chloramine removal with that one . . . This one does though . . .reasonable value for 20,000 gallons at 94 quid . . . I use mine for drinking water as well.

In my fish house which is now going to be my brew house, I use a HMA filter to remove Chlorine ,Chloromine and other metals and particles. I was changing between 200/300 litres most days (30 tanks).
I take it that I can use this for my liquor?
For the fish it was slowly ran through the filter into a food grade barrel (280l) where it was warmed and circulated over night, For beer would this be pointless, and should I just filter it straight into my Hlt ?

hould I just filter it straight into my Hlt ?

yep :thumb:
