at those prices i think i'll stick to the filters i have,

What! £38 + vat :Image4:

These filters will actually save you time and money in quite a short time.Each 20" filter will replace 3x twin filter sets. So you take out your current 20" sediment filter and 20" carbon filter and re-fit one canister and leave empty and then put the new filter in place of the carbon. This filter will then last up to 3x longer than a standard 20" twin-pack.

Working this out at our prices for a 20" twin pack this puts the cost difference at Fibredyne = £38+VAT v Standard Twin Packs = £59.25+VAT

A saving immediately - also factor in that you will have saved postage and time as well. Also these single pre-filters improve the through-flow of water at increased pressure which will improve the performance of the RO which will probably reduce your resin consumption as well saving you more money.

With time we will probably switch over to these filters completely as there is simply no need for old filter technology anymore.

So I take it it's just a carbon filter that has an outer layer of micron mesh inside aswell?

 

[Alex Gardiner]

It's quite a bit different to a standard carbon filter. The best explanation is on the technical PDF -

i have 3 10" filters on my static ro that last me 6 months without a problem, 2x 100gpd membrains that have now entered there 2nd year, resin wise im using only 1lt of resin every 2-3 weeks, i change it when water hits 002ppm. so its really cheap to run anyway, still got just under a bag of resin left that i brought feb last year. system is fitted with a flow ristrictor anyway so increasing the flow wont do anything due to the ristrictor!

tap water is 450ppm also.

my pre filters cost about £13 with p&p so for £26 for a years use i think is pritty good anyway.

Hi Richard
You have got one of the best low-cost set-ups available. If you have a good size holding tank and do not need a rapid fill-up then this is a great low-cost way of treating water – as long as you are not on a water meter as they are quite wasteful of water. I also used exactly the same 200gpd RO unit and a 1000 litre IBC which kept myself and 2 other workers supplied with water for about 7 years until I switched to a 4040 for more rapid fill times.

Because I had 100psi water at 85ppm I usually got about 001-002ppm from the RO and as a result used very little resin in a year. 2-3 years for the membranes was about standard for me. I did try and change the pre-filters every 3-4 months though as the water round here is quite full of mud which clogs up the pre-filters more quickly.

Even on your set-up though you would save money eventually with Fibredyne filters as instead of changing every 6 months you could stretch that to every 12-18 months. We have been conditioned by some of the main domestic RO manufacturers (100-300gpd) of the need for 3 pre-filters when actually 2 have always been sufficient on UK water supplies and now with new technology 1 is sufficient.

Personally I have always hated changing pre-filters so having to change less often and only changing one filter really appeals to me.

Other filter manufacturers also do similar all-in-one options but with not the same water through-flow rates which is why we went for the Pentair Fibredyne option.

yer its into a 1000lt ibc tank, i like this way the best, 1, have the room for it, 2 save on weight in the van so working from a berlingo the more weight you save on things the bettter,

im on a water meter and with the tarrif we are on it only costs me around £9 for each 1000lts of pure water i produce, 2000lts waste 1000lts pure.

we are just sorting out and starting a window cleaning suppies shop in Northampton as the closest ones to us is in wolvahampton and london, there are a few places that sell little trad gear but thats it, nothing for water fed pole, so things will be getteing cheaper still.

Im always out with my ro checking and cleaning it as we had a legionnaires scare last year with our daughter when she was rushed into hospital with similar symptoms

as it, luckly it wasnt but since then im always checking and cleaning ro to keep it as clean as possible,

Got to say im not sure i would feel confident just running this one filter, im not to convinced about it, Alex i take it you have tested this? and did you notice much of a pressure gain when using this?

 

[Smurf]

Alex would it be any good to use it to filter dirty rainwater collected from guttering?

 

[DanC]

Bit gutted i only just upgraded my pre filters this week, wish i knew this was coming out!! I would of brought one and given it a go! Ive just gone over to a 1 micron sediment too

 

[Alex Gardiner]

Alex would it be any good to use it to filter dirty rainwater collected from guttering?

It would be slight overkill as a lot of these filters ability is in getting rid of Chlorine which rainwater does not have. A good quality mesh strainer followed by a sediment filter would be best for rainwater.

There is a significant and measurable pressure gain (depending on exact water inlet pressure and water temperature) which can have an effect on the membrane depending on exact efficiency of the membrane in your specific system setup.
I have left the technical testing of these to those far more knowledgeable than myself in the art of filtration. I have these filters ready for my next filter change (about 1 month's time).

I have the new Merlin RO system it throws out so much waste water !! Would i have to get a new RO system that doesn't throw out so much waste or is there anything I can do to minimise the waste?

The Merlin does waste a lot of water - as far as I know there is nothing that can be done to alter this.

 

[Neil]

Argh gutted how much would it cost for one that doesn't waste a lot of water? By the way Alex I ordered a few bits from your company yesterday and your team are brilliant really helped me out with what I needed.

 

[Alex Gardiner]

It depends really on your water quality - what is your input TDS and water pressure?

 

[Neil]

Tds reads 270ppm pressure comes into my Merlin at 80psi without a booster which I am happy with but too much waste water /emoticons/sad.png

If you were running a 4021 or 4040 based system then you could probably get away with about 50/50 waste ratio - 1000 litres of waste to 1000 litres of pure.

If you are not on a water meter though it probably does not matter unless the waste water is not running into a drain.

 

[Smurf]

So Alex do you intend to start selling wfp rainwater harvesting filtration systems as there is no one about selling good kit most suited for window cleaners?

What ppl would be looking for is an off the shelf kit that will maximize collection and filter rainwater before going into holding tanks.

Any Ideas?

It would be slight overkill as a lot of these filters ability is in getting rid of Chlorine which rainwater does not have. A good quality mesh strainer followed by a sediment filter would be best for rainwater.
