    Evening - came across your site when searching for information and thought you might be able to help me :)

    I am using a DI system for reducing a TDS of 280ppm to 0ppm for car washing purposes - private not commercial

    I had no problems using purolite mb-400 and it lasted for about 4/6 months before showing 4/5ppm and I changed it.

    I moved to Unger and could not get a ppm lower than 10 from the start, moved back to purolite mb-400 and everything is good

    My questions - I am looking to buy another 25l and have been told that I should be ok with Tulison mb-115 with seems to be more widely available. Are the mb-400 and mb-115 interchangeable or should I stick with the product that I know works and buy 2/3 to stock up :)

    Cheers for reading :)

    Depends really mate, mb-115 will bring the tds to 0 but i really doubt itll last 4/6months if your d.i only from 280ppm....
    I'd stick to the stuff your using if it lasts that long and you're happy with it, or buy an r.o system and have it producing into a few ibc''s.
    Then use a bilge pump to draw the water from the ibcs onto your cars....(no idea if viable though as i know nothing about washing cars)

    An RO would create too much waste water - this way I can have the DI vessel in line with the pressure washer.

    Normally 2 or 3 bags a year depending on cleaning and dirt and water quality

    Average 175 litres a week

    Tulison mb-115 is the best stuff and also to save you a few quid 4-5ppm is fine to wash you can go up to 15 ppm no problem cleaning windows so I would have even higher cleaning motors

    Thanks - I might give it a try - after being bitten by the Unger was concerned about changing.

    4-5ppm still leaves faint small water spots - I run to 0 based on my need for OCD ;)

    Agreed - but the drive is south facing and can dry very quickly under bright sun.

    Based on the coatings I have on the car using 0ppm actually leaves a better shine and does not impede the hydrophobic properties of the coating.

    on that question - what it is the best way to dispose of the used Resin?

    How about going dual di? Running water through 2 vessels?

    I noticed my ppm jumping up to 006 last week, so instead of buying another bag of resin, I bought another di filled, so I have my first vessel in 1st position, bringing my tap water down to 006, then my new vessel in 2nd polishing it off to 000.. I usually get 6-8 weeks from 1 11lt vessel.. 280ppm is high for just using resin and I think you would benefit a lot more using twin di vessels?

    I have only ever used unger resin and I find it great for me, my ppm is only 40... But I have heard a few on this forum mention they thought unger was better than tulsion..
