    my research has shown that the use of granular activated carbon with slow disolving phospate helps prevent scale so what do you all think ?.
    poddy66

    Slow dissolving phosphates do help reduce scale formation..... mainly in things like washing machines and dishwashers.... (ever heard of Calgon)

    The problem is to get a reasonable level of protection the dose must be quite high and its effectiveness at preventing scale reduces significantly at boiling point - which is where we need it.

    Im not sure Id want to have phosphates in my coffee . They are fine for reducing the scratchiness of fabrics and getting a gleam on glassware.

    Phosphate softening products are no longer sold in the US because of the environmental pollution they cause - they also dont like the ion exchange units because of the salt recharge (but at least the salt came from the ocean and is going back there)

    Re: Water filters

    Hi All

    This is my first post and I am glad I stumbled onto the site!

    We are in Adelaide and Adelaides water has a notorious reputation, although it has improved over the past few years. We have a WaterWays filtration system which is a tap plumbed in to our sink. I love it! I dont know if they are available interstate but would personally not have Puratap (another company) which I believe has expanded into Queensland.

    We have a Nuova Simonella and hubby has thrown out all instant coffee, never to be bought again! It is a bit of a struggle at work now, because everything tastes blah and yes, my boss thinks Moccona is gourmet!

    Fair enough poddy66,

    Looks like we were both trying to offer the same advice but in different ways.... And unlike you mate, I am not a professional in this area, just a user .... Sorry if I came across as trying to have a dig at you, I wasnt, just trying to be helpful is all.

    All the best,
    Mal.

    Re: Water filters

    i have been a plumber for 20 years and have had good experiance in the field good postings on water filter systems my previous posts my have been a bit short and not understood sorry for that coffee snobs.I have been looking further into the scale i agree in re-gard to mixed- bed ion exchange resin together wth granular activated carbon this aplication would remove 99.8% of total disolved solid from the water. my research has shown that the use of granular activated carbon with slow disolving phospate helps prevent scale so what do you all think ?.i am not a sales person for filters nor do work for a filter company hope my imput has been helpful cheers steven poddy66

    I just removed a whole lot of noise in an otherwise interesting thread.  

    I think poddy66 should have another go at posting his thoughts on filter systems (without attacks and without making it an ad for someone) so we can get some differing opinions.



    Be nice people. 8-)

    Re: Water filters

    From what I have gleaned about filters (extensive research when installing a pressurised drinking water system on my cruiser), Mal is right.

    I wont bore you with the details, but most filters will use activated charcoal, usually made by burning cocoanut husks.

    Activated charcoal removes malodorous substances and the larger particle contaminants. The charcoal has a very lare surface area.

    Otherwise, if the waters only problem is "dirt" it could be removed by the traditional method of passing through a big sand mass, as in swimming pools. But obviously impractical for domestic application.

    Ion exchange--those periods of chemistry and valencies at school are finally paying off---handles magnesium and calcium which, when heated by the element, produce the familiar rusty-coloured limescale.

    Because tap water has been treated with chlorine as the most common disinfectant, the chlorine actually stops bacteria growing within the filter. Up until the point where the filter needs changing because it is saturated.

    To be effective, the filter must remain submerged in water. This isnt always possible --- on our boat we may not be there for weeks at a time.

    So, in that situation, to prevent bacteria growing, activated charcoal impregnated with silver is used. And the cost of cartridges blows out to about $70.

    Hope this doesnt muddy the waters too much.

    You can see the persons location, assuming theyve entered it, by hovering your cursor over the flag under their nick to the left of the post.

    counter top model kdf carbon filter will do the trick a diverter valve is fitted to the tap cheers poddy66
    Gday P66,

    Actually mate, the Carbon Filters only remove some chemical contaminants, some metals and some odours. To get rid of Scale Producing Compounds you need either a Water Softener that is permanently connected in to your mains water system or a filter with a specially treated resin compound that removes them via an ionic process. The second option though requires regular filter replacement to maintain efficacy where-as the Water Softener will just require regular reverse flushing and recharging.... Works out cheaper in the long run.

    Mal.

    For anyone else who has been wondering how Fatboy could see that Coffee Kid lives in Brisbane, click on Profile/Modify/*enter password*/Options.  At the bottom is an option to View location in posts - check the text option and click on change profile.  Voila - suddenly I can see where people live, if theyve entered that information of course.

    Very off topic I know......

    Re: Water filters

    Ah, well it must be a setting in Profile then.

    I have input my location in my profile and see it when I make a post. If other people have put in their locations (like Coffee Kid, Brisbane, Queensland, Australia), I can also see them.

    I thought it was a default.

    My apologies.

    Brett.
