New axeon low pressure 4040 ro membrane

[chrisb2]

Hi all. I have put a brand new Axeon low pressure 4040 ro membrane in and it's taking my tds water down to 65ppm from 380ppm. Surely that's not right? I thing I don't know is my tap pressure. It goes through the 2 pre filters too.
What should it be taking it down to after the membrane?
Any help would be great.
Thanks

Flush flush flush

As suggested, you should flush it for at least 4 hours. A new membrane, operating in the right conditions should reduce your TDS of 380ppm to below 15ppm

Any new high quality membrane will be saturated in brine.. flush it well

Although it's a low pressure membrane, does it still need a booster pump? I believe my ro membrane is the same, and for it to run at 80psi it needs a booster pump.

To get the best and more importantly long lasting results get a booster pump
my water TDS ranges from 320 to 400 and after the RO I get 006

is it defo a genuine Aexion ?

When i first installed my Axeon hf5 it's rejection rate was 98%. It was just a quick flush. 12 years later it's 97%.
50 to 55psi tap water pressure, no booster, 13lpm from the tap and tap water tds between 120 and 145ppm.
It's usually around 124ppm area.

at 120 ppm you can almost use it without filtering

We are very fortunate when I see the water some window cleaners have to content with.

They don't make them like they used to

When I bought mine 4 years ago that's about what I was getting too. Defo need a booster pump to help.

Someone might take that as a true fact. Water so hard it almost stands up

How are you getting on? I've just installed a new Axeon 4040 HF5 with new pre filters. With a tap pressure of 60psi and a TDS of 390ppm () it's brought it down to around 11ppm which I'm extremely happy about.

I flushed it for 3.5hours first before turning it to produce pure.

Hope you're getting better results?
