  I've managed to get a link to a chemist who has knowledge of Resin and
  works in a company that produces it. One thing I have noticed is the lack
  of knowledge in the fundamental properties of WFP. We know how it works
  but not the ins and outs of it.

  I know Mixed Bed Resin is made up of Cation and Anion Resins and the best
  quality is 50us mesh. What I would like to know is a bit more about it as it
  would be nice to know how it works and a lot of questions on here people
  have different veiws.

  I did see someone was supplying 60/40 mix but I'm sure 50/50 is better
  quality.

  Hence my sourcing of someone who could help me answer the following
  questions :-

  What is the formula intake of resin ie:- if my water is x tds how long would
  x litres last.
  What is the best quality and would it be more cost effective to buy quality
  resin than basic resin.
  The most asked question, what TDS can you wash windows at.
  What does cation and anion absorb.

  These are a few questions I am going to put to him, if anybody else has
  any other questions please post them and I will forward them onto him.
  I'm hoping he will be able to answer these questions so I can understand
  a bit more about WFP and look into reducing my running costs and finding
  the best product. This guy will be unbiased as he does not work for the
  current 2 selling products.

  Thanks

ok D.A having studied Chemical Engineering at Uni I should be able to answer this ok.

1)the formula is 500,000/tds = litres pure water per bag ( I think thats up to 5ppm, not sure about that but its close)

example, my tap tds is 300 so therefore 500,000/300 = 1666ltrs

2)the best quality resin is probably rohm and haas although for the money I prefer Dowex (www.surecleansystems.com),

3)I never go above 1ppm when working, others use water much higher around 8/10 but its up to you

What I would like to know is this. Is the spent resin beneficial to your garden.
I was thinking that since all the minerals are concentrated, it should make a good fertiliser. Any thoughts? Dai

  Cheers JM123,

  Your formula seems pretty close, reason why I am looking into this is I think
  as an industry we are being hood winked by some major players in our
  industry. I found this out when going the DIY route and getting quotes
  on parts etc...

  I'll give you an example that does happen every day, each morning petrol
  stations will ring each other to see what the going rate is for petrol. That's
  why you will drive around and see prices always the same, this does happen.

   I will not name names etc.. but in my enquiries I found certain products if you
   were a new supplier you could not sell the product at a lower price than other
   suppliers. I am not going to say the word, work it out for yourself. It does
   happen in our industry and it is legal.

    Hence my search to try to min. our running costs and all the questions I am
    asking. We are all on here to save costs but our industry I feel will not tell
    us.

    To be blunt some company's offer good prices for example Gardners but on
    some parts they will never compete on other companys 
    Work it out yourselves, please do not ask me for examples. I was told this
    info by actual manufacturers so I will always keep this info as it is their jobs.

    There are 2 major suppliers for resin, to drop the price I think there needs to
    be a couple of new players coming on board. I'm using my skills to help
    me and this industry, some prices are fair some are not.

    Thats all I have to say so guys please help us with the questions I ask and I will
    see what the best I can do.

  If thats the case we do not need WFP in Scotland, TDS no more than 40 

   No one can say what the standard is 

   Only helping.

wfp is  a growing industry and getting bigger every year,    I dont think they will ever dramaticly drop the price of resin, if they did, say to £15 £20 a bag, their would be no need for ro systems,   ect, the only excuse manufacturers have is its expencive to produce,    rubbish i say,   like everything else the more you make the less it costs,  when ever a new player comes on to the market selling resin, its not long before they are bought out,

[sair]

as a supplier of resin we have supplied most over the years

Rohm and Hass is just one of the better known names as is dowex i would not concluded that just because you know the name its the best

i have dealt with ionac now for over 6 months and there product is performng more consistantly than when we supplied rohm and hass.

seeing the price come down would be nice as its a big investment for supliers buying in so much at a time , i dont think they will lower the purchse price most companies charge the same to all suppliers the price breaks come when you order in excess of 5 cubic meters thats a lot to supply each month

[Moderator David@stives]

Purolite resin is considered the best by some.

I have got 100 litres of resin in my shed waiting to be disposed of or re-used some how, so some good tips there would be useful

[Trevor Knight]

WOW, the only information I need to know is HOW MUCH!!

Rohm, Hass, Dowex, Cation, Anion sounds like egyptian to me 

Who said window cleaners are not intelligent.

Still guy's, if your window cleaning business doesn't hit it off you could always go and work for NASSA.

Best wishes,

Trev

  Quick question guys,

  Would you buy resin that is not a well known brand in the UK but has the same
  properties for £75 all in, this includes delivery.

  I have a foreign supplier wishing to offer their MB resin to us window cleaners.

  If not what is a fair price, serious answers please.

  Also he has answered above questions and also enlightened me that there
  is an alterantive method other than using R/O.

  Cheers

you can go up to 15/20+ppm if your cleaning regular work and even new, I know some who have used it at 35ppm and it comes up good.

My ppm is 360 from the tap, but just one mile from my house i have a relative and her ppm is only 30, i am right on the boarder between a hard water area and a soft water area.

so only one way to find out if you can clean o.k with 30ppm is do it. I
have ordered a back pack will test it out when it arrives and post results for you all.

Cheers
JEFF.

  Guys,

  I take it no one is interested in buying resin, I'm just looking into this so
  as to reduce my overheads. Not looking to make any money.

  I think the price of resin could be driven down in this market, one way of
  doing it is to get another manufacturer on board. Hence my market research,
  there are other ways to get cheaper resin but still investigating.

  Think I will limit this to WFP users in Scotland, the asking price is still to high.
  If things go to plan hopefuly anyone interested in Scotland 25l bag of resin
  for around £60 + delivery.

  Will take time to set this up and will need some guys to test this product. Just
  looking at ways to cut my costs.

  Dave :- Resin can be dumped in land fill sites so I presume your bin.

  One thing he has pointed out to me is that the inlet/outlet flow rate effects the
  life of resin. He has the data which he will send me.

  I know it's technical but with the current climate of fuel rises I need to look at
  ways on cutting my overheads so any info that helps me is valuable.

  Cheers

3)I never go above 1ppm when working, others use water much higher around 8/10 but its up to you

1)That formula is very inaccurate, there are a lot of factors involved. If Rohm and Hass is better than Dowex surely the forumla doesnt work??

2) Absolute rubbish, Rohm and Hass is far from the best probably one of the least performing resins out there.

3) You can go up to 15/20+ppm if your cleaning regular work and even new, I know some who have used it at 35ppm and it comes up good.

ok foxman, its only a general formula as each mfr has their own blend of anionic and cationic resins, as for rohm and haas being one of the poorest resins, if thats your experience then fine - my experience is that purolite is rubbish and r+h is really good, as is dowex, again 2 people may both have water at 50ppm,however the same resin may work differently with one sample of water over the other due to the mineral make up of the water, so you can see I'm only generalising my findings.  Lastly if you feel you can use water at 35ppm then again, fine, I know I wouldn't go above 1ppm, my customers expect perfect results so thats my choice.

[beefy]

doug id be interested in resin at that price,im not based in scotland but i go to n.ayrshire at least once a month, my ppm is 35 so im not sure how much im gonna use though
cheers beefy

[mikeflies]

if TDS is 200ppm, 1 litre of resin will give 100ltr of water.

easy enough to work it out from there
