Ppm rising a lot quicker than normal

[Amos]

Hi guys as a complete novice I have noticed that my ppm is going up a lot quicker than usual and I'm putting a lot more resin in then I have done in the past I've put brand-new resin filled the tank up last week then filled it up again this morning and noticed that my ppm was 20 any idea guys !

Wat is ur ppm startling at

 

[Amos]

Obviously when I put new resin in it's 0 ppm it used to last for weeks but now it's a matter of days last time I checked it was 20 ppm after a matter of days Pete

You filled the vessel up this morning and the PPM was 020? Are you DI only, what's the TDS input?

 

[spruce]

We presume that the system you got from Baileys has a 4040 r/o @Amos.

You need to take a reading of your tap water and then a reading of the pure water coming out from the r/o BEFORE the di vessel. That will tell you the state of your membrane.

If the membrane isn't working efficiently then your resin use will increase.

Some people say that Resin has gone down in quality I'm not sure.

I was going to ask is there such a thing as dodger resin cos it used to last soooo much longer than the pack I got recently

Ouch time to change your membranes. You should be getting between 12 to 7 depending on pressure and make of membrane

You see I know absolutely nothing on the mechanics of ro systems etc just know the basics i.e. Put new resin in when ppm going up lol these membranes are only 7 months old !! What am I doing wrong ??

Try taking everything apart (marking every pipe accordingly) and putting back together as had this problem a while back and cured it.. also did you apply silicone around the rubber seals on your membranes when you changed them.

As @doug atkinson says, its your membranes that are causing high resin use.

When you are purifying water how much waste do you have to the amount of pure you produce? Is it 1 liter of waste to 1 liter of pure for example?

When did you last change your carbon filter?

I like MB 115 tulsion , its a good quality ! Heard bad things about unger though ... i dont know how much you fill your resin vessel but ive had good exp. In not filling higher than to where it starts to bend at the top.

 

[doug atkinson]

Amos see you can upload a picture of your r/o set up

 

[Amos]

Right please bear with me spruce , how do I gauge how much waste and amount of pure water ?

You could time how long it takes you to produce 1 liter of pure water after your r/o or di vessel and then time how long it takes to fill a liter container with waste water. Please can you take a photo of your r/o system as @doug atkinson has asked.

Can you do a side view as well as looking at that photo I don't know if your waste bottom and pure top are joined together. On the photo it looks like it but may be wrong
