Dodgy tulsionmb115???

[Metcalfes window cleaning]

Hello.

Is there some rubbish mb115 going about? I only ask because before going into a 19ltr di vessel, its coming out of my RO at 12ppm from 360/370.. And coming out of the DI still only at 1ppm...???

Nice one, Scott!

Where did you get it from? I got mine from Daqua and its fine

 

[tench0771]

my last bag was from daqua an i wasent inpressed ive now gone bk to unger resin

 

[doug atkinson]

Mind me asking where did you get it from, thanks

 

[doug atkinson]

I will be doing a video in the next week or so which will show why so many people are having problems and throwing good perfect resin away !!

Excellent Doug, look forward to that.:thumbsup:

It was from PureFreedom, and it took 5 days to be deliverd!

 

[doug atkinson]

Okay thanks this is one not for us. Just to clarify this is not the MB-115 which we sell and soon this will be sorted out where our qc products will be identified and marked so the MB-115 name we sell does not get dragged not with what is happening.

@tench0771 bought a bag from you @doug atkinson and wasn't impressed. Mine went from 002 to 012 from last night to tonight, WTF is that all about . I buy mine from http://www.osmotics.co.uk. Never had it rise that much after filling the tank with about 300L.

It's not a patch on what it used to be.

 

[Scots lad]

I've had all of mine off Doug and never had a problem

 

[doug atkinson]

Have you changed your distribution vessel since then Tony. I have been doing long trials even with a bag returned.

Replicating the customers set up I can see the problem, I then change the parameters and monitor the out put and I had to give up in the end due to time and I was still getting 000.

There will be thousands of these distribution systems out there but by changing the parameters the resin is producing more pure water.

Just need to figure out the route cause.

Hi Doug

I changed both vessels for new ones and the results were just the same. I also clear both internal strainers on every resin change so as to eliminate that too. I'm at a loss as to such a drastic reduction in 000 filtration performance. I've tried other resins too with the same and worse results. Tulsion used to be head and shoulders above other resins but it's now on par with most others- which are also generally performing much worse than they used to. It makes me wonder whether it's the manufactures who are chancing their arm in supplying a reduced quality of resin for this market. Don't know what happened to Dowex but their MB50 used to be on par with what Tulsion used to be.

From Alex G

That is two different types of MB-115!

Which is why going forward (but not happened quite yet) they will be differentiated by the addition of the suffix SB to the superior supply. Hopefully this will enable clients to make an informed choice about their resin supply - the superior supply may cost a pound or so more, but it will be guaranteed to perform to the usual high Tulsion standard.

Currently there are two wholesale importers bringing Tulsion products into the UK. The product specification differs between the products imported by the wholesaler that we use and the wholesaler that most others use. The wholesale importer that we source through has a quality-checked and assured strong base resin based on a tight manufacturing and testing specification whereas the other wholesale importer supplies resin without a set specification meaning the quality cannot be guaranteed.

Each year we see a few posts popping up on forums stating that the quality of MB-115 is of not of a high standard. When the wholesale importer has checked on the supply of 'this' resin they find that it has not come from the batches they import and are always from the batches imported by the other wholesale importer which are of a lesser specification.

Hope that has clarified this

 

[♠Winp®oClean♠]

All batches if Tulsion I have used have been the same regardless of supplier.

 

[doug atkinson]

The specification has not changed it's still the same so baffled why some people see no difference and others do.

One thing that has changed in the market is the distribution systems which now having done lot of testing I think I have found the answer.

You may have a brand new distribution system but under certain pressures will not perform to the capability of the resin.As a result resin is blamed but in fact there is still loads of life in it.

You will never get the same performance from different batches as there is a 3% +/- leeway against the spec. So at high ppm there would be minimal difference but at low ppm you would see more variance.

If you lived closer to us as soon as your ppm rose I'm sure I could bring it down by changing something!!

 

[♠Winp®oClean♠]

Not sure what you mean by certain pressures Doug? My system is almost pressure free, I purify on demand so only a very slow, pressure free flow is going through the resin. I have no doubt that something has changed. After 12 years of DI only experience and monitoring, resin has generally got worse in it's longevity- even taking all the obvious factors into the equation. I point the blame at the manufacturers.

 

[Poles Apart]

I get mine from Daqua I use twin 11 litre resin tanks my tap reading is about 75 ppm (used to be 55) I use between 200 litres and 300 litres per day and changed the resin in number I tank only and switched tanks, still going after about 10 weeks, can't see a problem, only gripe from me is why is it so expensive?

 

[doug atkinson]

Tony I've replicated your set on demand and pressure is an impact as your pump is 100 psi so in your vessel you are creating that pressure. Here is a hand shake with you, as soon as your ppm goes up I will meet you with a distribution system and I'm 99% sure your ppm will drop. If it does for a whole month you have to be with your misses every Sunday where ever she goes , how about it /emoticons/wink.png
