    I know if you boil it, it opens the pores & does a better job as per @LuckyFish but not sure if you can boil it again & reuse it...

    As far as I am aware it is not rechargeable, although I'm no expert in this area so just sharing my understanding.

    In my experience you could look to an alternate product like Purigen, which offers the same benefit as charcoal but is able to be regenerated with a simple Jik dip.

    nope throw it away after 30 days, use 1ml per L
    do not fluidise it heavily at all

    i agree with @Nemeziz_za purigen is a great product and can be regenerated

    Nope, definitely not reusable / rechargeable...
    Carbon absorbs chemicals, & once it has reached its limit, It might slowly leach back into the water.
    Haven't ever heard of anyone trying to recharge it again.
    I usually just chuck it all, & get some new charcoal...
    I used to buy it in bulk from RO filtration suppliers at +- R5 per kg.

    It is possible to re-activate but it needs to be heated several hundred degrees (much more than a conventional domestic oven) so no economical on our scale unfortunately.

    Yup agree can be reactivated, used to do it all the time on the Gold plants, but need s to be washed and then dried at high temp for long time, cheaper to chuck away and buy new.

    Thanks Dave,
    When you say high temp if I do go this route, that means drying it out in the oven for about 2 hours,

    Drying out will crystalise what already on charcoal. Take a kettle of boiling water and pour it onto your drained charcoal. It will release heaps of muck.it xan also be boiled on stove. Rinsed in ro and boiled again till clean. This cannot be done with carbon or formed charcoal as it will disintegrate

    It can't be done at home at an affordable amount. Kiln at 800 degrees for 24 hours, that is after it has been washed, with acid and other chemicals. It is really not coat effective.

    Guys technically the answer would be yes it can be reactivated. Can it be reactivated economically, considering the price of charcoal, the answer is no.
