Chlorine removal

[marmite]

I'm presently reviewing the results of a questionnaire sent out to MCB members on water treatment. One question relates to the steps taken to remove chlorine. Answers vary from no action at all to leaving to stand for varied lengths of time(20 mins-48 hours) with or without a campden tablet and an occasional charcoal filter and swishing about. What do members of the forum do and exactly what is "best practice"?

I'm not sure what's best practise but I put a quarter of campden tablet in for strike water and then another quarter in the sparge water.

I run a second line from the aquarium hma filter :)

I use a campden tablet. Chlorine is easy to remove but chloramine is harder, hence the campden.

 

[PD]

I put in half a campden tablet and let the water stand for a couple of hours

 

[danb]

How much campden rpt?

 

[dennisking]

And use campden but I have began to wonder. Twice in the last year I've forgot and not had a problem just do it out of habit.

 

[PD]

I use half a tablet in my hlt water of about 60 litres

1/2 a tablet? i use a full one for 30L, just because i cannot be ar*ed to split them lol

 

[danb]

I use half in 50 odd litres, should I be using less :wha: I'm not sure, I have had no weird flavours or problems so I think I'll stick as I am for now.

 

[rpt]

I use a whole tablet in 34L. Probably need less but my tub of 50 is still going to last ages.

I read somewhere that when doing AG it may not be necessary as the boil gets rid of it. I may be corrected here.

I do not treat, as I currently use ASDA Smart Price water

I don't use anything but I just brew kits. The bloke at lhbs told me recently I needn't bother with camden tablets but if I had concerns with water to fill FV the day before and use it when brewing

 

[rpt]

Boiling will get rid of chlorine but not chloramine.

 

[hyperlink]

Bear in mind that the levels of chlorine and chloromine in water will vary depending on a number of factors including seasons, time of day, day of the week and location so what works for one may not be suitable for others. There is no right answer.

quarter crushed in mash water , quarter crushed in sparge water . Water used straight away no waiting .

 

[Steve]

1/2 tab in water while heating to strike...when I remember. Not noticed any difference in the brews that I forgot to add it and to be honest I'm not sure which it was I forgot to add it to from memory or from taste either.

1/2 a tad in 25l and leave between 1hour to over night.

Hi, campden tabs won't remove the more frequently used chloramines in tap water.
The product to use, if you are that bothered by them is sodium thiosulphate, (the stuff used in expensive
fish tank dechlorinators). This is used in tiny quantities and breaks down into ammonia (yeast food)!

Actually metabisulphite will remove chloramines, there was a good article about it 3 or 4 years ago in Brewers Contact . . . Which is summarised showing the reaction at Jims Beer Kit
