Chlorine/ Chloramine removal by Catalytic Carbon Filtration

SAVE THE MICROBES!

Most water providers use chlorine to sanitize drinking water, which is problematic. As a result, we must dechlorinate water before utilizing it for organic gardening purposes.

To remove chlorine and chloramines from water, carbon filters and reverse osmosis units are two common options.
Dechlorinating products, ascorbic acids, and Campden tablet treatment are also utilized.

I personally use the Boogie Blue PLUS+ Brand of High capacity Catalytic Carbon filter rated at a 45,000 gallon lifespan. A quick search will uncover other filters, some cheaper, but I like my boogie brew garden hose threaded filter and highly recommend them if you want to do more than imagine that one has a living soil garden after unknowingly, routinely molesting the soil microbes with chloramines.

A Catalytic Carbon Filter is one of the most frequent techniques of removing chloramines from a drinking water supply with reverse osmosis water being another.​

1-First-Image.jpg There are a variety of filtration alternatives for this sort of filter, including a catalytic carbon pitcher filter, a whole-house catalytic carbon filter, and even filtering bottles.​


The surface area of a catalytic carbon filtering cartridge is as large as possible, which helps to boost activity and ensures that the filter media can absorb chloramines and considerably reduce them in water.

Chloramines are attracted to the media and cling to its surface when drinking water containing chloramines goes through a catalytic carbon filter. The filter material does not attract water particles, therefore they flow through to the opposite side.

A catalytic carbon filtering cartridge may only be used for so long before its pores become too clogged to function properly, resulting in poor flow and efficiency. That’s why it’s critical to change your filter according to the manufacturer’s instructions, whether that’s every 6 weeks or every 6 months otherwise your just harassing those desirable microherds of resident organisms.

What’s the Difference Between Chlorine and Chloramine?​

Chlorine is a chemical in and of itself, whereas chloramine is a mixture of chlorine and ammonia.
When chlorine and ammonia are combined, the resulting chloramine is more stable and may stay in the water for longer when exposed to air.
This is beneficial in terms of home water disinfection since it ensures that chloramines do not leave your water before it enters your home. Chlorine evaporates more quickly when it is not combined with ammonia.

When it comes to removing chlorine and chloramine from water, there is a significant difference.
Contact your water company customer service and ask them what chemical they use to disinfect with.
To get rid of chlorine, simply leave tap water out for a few days, and it will evaporate into the air. Aeration accelerates the process.

Chloramines, on the other hand, are a more complicated mix of ammonia and free chlorine, thus they can’t accomplish this.
If your water includes chloramines, you’ll need to look into specialised extraction methods for this chemical as to source pure-ish, chemical free water for Organic Gardening purposes.
The various dechlorinating products, ascorbic acids, and Campden (powder/tablets) treatment are also commonly utilized.

The BBplus' apparent premium quality, with its dual catalytic-carbon & KDF membrane, the PLUS+ model contains MORE carbon, (almost 6 oz more) and MORE chlorine & chloramine-scrubbing KDF material, (11oz of KDF).
Furthermore, the carbon membrane has been improved to include a superior grade of catalytic material, (Resin-Ion Exchange), which has shown great promise at arresting increased levels of heavy-metals.

If any other companies have comparable quality offerings "out-there", I'd like to know of them.

Happy Microbe farming,

That sea chem will certainly do the "trick" quite well.
I see by reading around that ascorbic acid powder @ about a half teaspoon per 25ish gallons is a popular and affordable 10 minute technique to neutralise those nasty good for nothing in the garden chloramines. :)

That’s a nice one, better than most…. But

If you think your outdoor garden hose & municipal water supply chlorine is impacting your soil biology to any level where filtering with the above impacts it; then your microbial life is tenuous at best and already hanging on by the skimpiest of threads…

I grow just about everything one can outside here and with plenty unfiltered muni water and it’s been 100% organic here a very long time… life thrives here in every form, the chlorine impacts it not at all… not one bit

Things to focus on when farming vs other things; one only has so much time to pick & choose, anything that restricts water flow for me here, outside is in the ways……

Happy growing - humble advice

I have transitioned to hauling city water when my rural well went dry recently, thus my recent forays into attempts at filtration as disinfectants in my water supply never has been a problem or concern for me the past twenty years or so.
I found this post regarding Vitamin C and the use of Humic Acids as a chloramine neutraliser at an instant compost tea products related forum and found some relevant to this thread information in it, so here it is....

"Just thought I’d share some ways to remove chloramines from your water without the need to buy and plumb a KDF dechlorination filter.
This High Times article (dead link) goes over some of the methods, including using campden tablets, aquarium dechlorinator and Vitamin C to remove chloramines from tap water.
According to that article, aquarium dechlorinator and campden tablets will raise your PPM by adding sulfur and sodium, while Vitamin C will only lower your PH.

This United States Department of Agriculture article goes over the pros and cons of two different forms of Vitamin C (ascorbic acid and sodium ascorbate) commonly used to dechlorinate water.
Sodium ascorbate affects pH less than the ascorbic acid.

By using a calculator/ spreadsheet I’ve found that about 50 milligrams (0.05 grams) of ascorbic acid or 57 milligrams of sodium ascorbate is enough to treat one gallon of water with a chloramine concentration of 3.8 PPM which is what my areas water has tested at (anywhere from 0.09-3.8 PPM actually).
The highest Chloramine amount allowed federally is 4 PPM.
You can search online for your local water report.

The cheapest I found ascorbic acid is on Amazon.
Sodium ascorbate is also available on Amazon.
A kilogram of either of costs about $20.
A kilo of ascorbic acid will treat 20,000 gallons and a kilo of sodium ascorbate will treat a little over 17,500 gallons.
Ascorbic Acid can also be found at health food stores in the supplement isles in the form of 500 milligram or 1000 milligram Vitamin C tablets.
Be sure to buy tablets which do not contain rose hips or any other extra ingredients.
Each 1000mg tablet should be able to treat 20 gallons of tap water with a chloramine concentration of 3.8 PPM

According to this article and multiple, more scholarly and difficult-to-read sources (Google: humic acid dechlorination), you can also use humic acid to dechlorinate water. Could the humic acid in Recharge be why Scotty doesn’t see a difference between tap water and dechlorinated water when looking at Recharge under a microscope? If that is the case, then Recharge users and compost tea brewers who are incorporating humus in their compost tea can probably skip using KDF filters, aquarium dechlorinator and Vitamin C.

I'm not convinced that locking my chlorine products up with sodium (making bleaching products) is particularly useful. Okay we are talking 10ppm, but every single time. That chlorine would find metals and make chlorides anyway, so giving it sodium to do it before application, just seems like adding salt to the wound.

I didn't do chemistry so maybe I'm missing something. However I'm convinced this is not needed after seeing a million examples. While the reasons to do it are shaky.

Humic acids all the way. Dribble a bit and stir. No color tint left after stirring? Dribble and stir again, and repeat till the water stays slightly tinted.

Humic acids are also great for plants. Win win. ;)

I've used ascorbic acid for years. It's great to toss a teaspoon into your bathwater too, if you live in a big city with really strong chlorine-totally removes the chlorine odor within seconds.

I see that some water companies standard operating procedure to help long term stabilisation of their chloramine dosed tap-water is by pre-filtering most humate content from the source water before dosing. :)

When has Scotty looked at Recharge under a microscope? I am highly skeptical of that claim......

Just about anything will complex chlorine and chloramine.
