A bit of maintenance

[Pjj]

So today after over 10 years of producing approximately 2,250 ltr of pure 5 days a week I have changed the membranes bit of a pig of a job getting them out of the housings as they had been in there that long the seals had dried up but after a lot of heat with a hot air gun and some WD40 got them out , and replaced them with DuPont ones from @doug atkinson at daqua also changed the resin and thought I would give the nuclear grade stuff a go , also changed the carbon sediment and 5 micron filters and the pre filters as well so hopefully won’t have to change anything for a while .

10 years isn't a bad lifespan! Keep us updated on how the DuPont membranes perform.

What make was the old type? Axeon.

No they were the original ones that came with the ros when new they are film tech the new ones are DuPont

I think the waters already really soft in his area? Wouldnt get that life in most areas.

Yes it is tap TDS 100 , but we do work in other areas ware the TDS 480

I’m doing maintenance too, attempting immersion hot water, changing hose on reel and all connectors to prevent any drips And changing over sediment and carbon filters. Not a fan of the jobs but it’ll keep me efficient over the winter.

10 years and that volume of water is some-going for one membrane

10 years and that volume of water is some-going for one membrane

It’s 2 membranes but still agree it’s lasted well

How's the storm been with you down there @Pjj ?

How's the storm been with you down there @Pjj ?

Been rough loads of trees down many roads closed and a lot of flooding , it’s calmed down now but still a lot of water and heavy showers . No work today ??? 77 mph winds last night according to culdrose naval air station 1 mile away .

@Pjj Tell me if you will, where you have 2 membranes does it go through sediment and carbon and then just break off at that splitter? Then does it come out the other end and just join up? Interested as I remember you said your waste to pure was much lower than the average because its double RO. I'm moving the RO from my garage to the office in the new year and the water cost is going to go up with the move.

 

[Pjj]

Yes just as you have said , my waste is lower as I choose how much to dump according to tap TDS when we are working in a very high area I find 50-50 works well at home with a low TDS I can get 80-20 , hope this makes sense ?

What you've said has just spiked my interest as I have a 40/21 on order and just made me think I might need to connect 1/2" hose to JG elbow outlets on the membrane for the waste and pure but looking online it will take days for them to be delivered ?

Thanks, Paul, delivery of these is between next Monday & Thursday be great if I could get some sooner local to me or from @doug atkinson who I'll phone in the morning to check it didn't cross my mind this morning, I was thinking i could just insert the 1/2" hose into the elbow fitting silly me

Try a local plumbers merchant some do sell them but not all, I tend to keep a small stock of anything like this that we use

As I have found out in this game, one can never have enough stuff. I used to buy one a two fittings at a time but now I buy a dozen and leave them in my spare box. ?

Your 'spares box' must be the size of a skip by now ?

I thought the waste to pure was about making sure the tds removed was washed away by the % of waste water.
Have you just guessed at the 50:50 to 80:20 or is there anything specific behind the numbers?
Considering your membranes have lasted 10 years you must be doing something right.
