    Drinking water filtration v coffee filtration

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all,
    A happy snap of the mushroom from the top of a Giotto group. This is a Melbourne machine..(apols for the crappy mobile snap)

    The owner has expensive triple underbench filtration for drinking water- which like most filters does nothing for scale.

    If youre using your fridge or the plumber installed a drinking water filter, it will most likely be doing little, if anything for calcium scale..

    Water for thought? *:-?

    Hi 2mcm

    Are you able to make a comparison between the outcomes of those types of filters and others. I for one use a Brita jug and am curious if the same would be happening in my Giotto.

    Hi Mal,

    I suggest that you could remove the mushroom (large top bolt) from your machine and add to the pix?

    regards

    Re: Drinking water filtration v coffee filtration


    I think its partly a case of you get what you pay for. Often, the problem is that you might go out and buy a pretty expensive filtration system only to find down the track that its pretty useless for coffee machine purposes.

    Enter Bombora! As part of our new fit-out Bernard was able to advise me on a filtration system to suit our machine and local water. There were a couple of options available and I ended up choosing the ScaleGuard Pro. It might be a bit of overkill for my circumstances as the thing is almost the size of a bazooka, but when you spend a bomb on your coffee machine it just seems like false economy to skimp on an effective preventative system.

    I dont know if any comparative studies have been done, but I suspect that if you were to calculate the lifetime cost of a Brita compared to a purpose designed system from Bombora, the Brita would be very likely to come out 2nd best.

    Mal, have a look at mine from a recent thread.

    I know Veneziano offer and use Hospitality grade RO Systems - meaning it produces absolutely pure water which is remineralised (so it is safe for the machine).

    Hi TG
    I did see that picture, but i note that i am fairly religious in replacing the cartridge when the counter advises us to, having said that i dont know how many litres of water each cartridge is rated for and i dont keep a track of how much water goes through each cartridge.

    I will take the machine apart next chance i get and take a look.

    Mine doesnt have a counter so I know I havent replaced it as often as recommended every time.

    Pulled the mushroom out of my giotto. Been using a brita jug but probably need to change the filter more often.... (Melbourne water)
    Nice and shiny under the scale :-)

    Re: Drinking water filtration v coffee filtration

    Hey folks,

    there is a bit of info in the post below that came up a little while ago
    http://coffeesnobs.com.au/YaBB.pl?num=1205410888

    some of it is relevant to this thread...

    As a comment: there is literature for and against Reverse Osmosis with re-mineralization(in terms of effectiveness of remineralization) my thoughts are that it is a tad overkill and the $ 1000 plus price tag (even more for commercial apps) is a bit prohibitive, not to mention flow rate issues, space and cost of upkeep.
    From my point of view the Scale Gard Pro that Den has is the poo of coffee machine filters...and one of the few dedicated filters that have been specifically developed to achieve an ideal PH for espresso(ie controlling water hardness without compromising mineral content)...i could bore you with this for hours

    cheers

    Re: Drinking water filtration v coffee filtration

    The "mushroom" in my VBM looked very similar to the one in the first post. I always assumed that Id be OK because my machine is plumbed through a drinking water filter.
    I contacted Bernard immediately after reading this post. He responded promptly & I now have the correct filter on its way. The best part is that Bernard was able to supply a drop in cartridge that will fit in my current set-up.

    BTW, whats the recommended chemical used to wash scale away from components & where can I get it?

    Evan.

    Re: Drinking water filtration v coffee filtration

    I use a re mineralizing system after filtration

    Time frame is 12 Months
    I just removed and inspected my mushroom and I got different results as to the colour

    After a quick but easily removed scale clean (just with a sponge & rinse)
    I noticed the green build up is only where the chrome was weak exposing the copper or brass

    Is it the the exposed copper or brass content the mushroom is made of that causes this?? As it did not affect any other part of the tube

    I use a wellness under sink system
    I wonder if Bombora has filters for my system??

    Re: Drinking water filtration v coffee filtration

    HI

    yes, both brass & copper can oxidize to form the green looking carbonate residue - as a rule they are fairly soft - its the calcium carbonate that gets really hard and difficult to remove.

    If i can get a picture of your current filter system configuration emailed through i could make a suggestion that may easily work in with what you have and keep costs minimal. Also, are you using town water or tank water??

    cheers

    Brisbane City town water
    Here is a picture of the filter cartridges from the net
    I believe my system Wellness S3 is now discontinued and a new system is replacing it mid 2009 ??

    On the R/O thing as someone who lives in a town fed by Sub Artesian bore water to get a really decent coffee the water needs better than a Brita Jug or Carbon filtration.

    A couple of the better restaurants and cafés have rain water tanks fitted but most just run carbon based filters :(

    Water on the back side of a medical R/O plant is still 120-130 milli Siemens and the front side is :P. No need to remineralise with this brew. As it is a pumped system waste is only around 20% not 90%+ like most unpumped systems. So called household R/O units for anything more than drinking water are no a good option unless you can reuse the waste.

    The point is I suppose that no one filtration solution suits all.
