Title: High Tds unsure what the problem is!
Post by: Ian.M on October 09, 2012, 06:28:49 pm
Hi chaps,
             I've been a long time time lurker around this forum but never really said much!I have a problem I was hoping one of you maybe able to shed some light on.I have a brodex RO 500 litre system which is only 8 months old (yes i regret buying it off them).

My tap water reading is 450,which is usual.I've just taken a reading of when it goes into the tank and that is about 77 and its coming out of the brush at 36!I have checked the resin there is plenty in there only changed it about a month or so ago.I also changed the filter as precaution as i thought this maybe a problem.Came home after i'd finished work today completely emptitied the tank,tripled check everything.Am i just making a rookie mistake and overlooking something?or is there a problem i would not know about? I also flush the system out reguarly!

I've been WFP since i got this system so it's all still relatively new!

Thanks in advance.

Take it back to them and ask them to go over everything with you. Explain what is happening and see if they can shed any light  on the problem. Do you have a adjustable waste valve when you are filling? You should be making water down in single figures after Pre Filters and RO, and then di resin should take this down to 000.0. You might not be letting enough water to waste when making your water.

Steve,
          thanks for your response.Never had this problem before,nor do i have adjustable valve that i am aware of!never had any issues like this previously!it wouldnt be the RO membrane would it?

Regards

450ppm is a high tap tds. Because of that you should probably get around 20ppm out of RO before it goes into resin to bring it down to 0ppm.
What tds reading was you getting when system was new before it went to resin vessel?
And have you done a pre-filter change since you had the system (should be done every 3-6 months)?

Swfc...yeah apologies!wish i had never bought from brodex but thats another story!pre filter was changed about 6 -8 weeks ago when i last changed resin and i changed it today aswell!

dont think it will be the resin unless its went off.

Is your "pure water" coming out of the ro faster or slower than what it was previously, or at about the same as before?
Title: Re: High Tds unsure what the problem is!
Post by: Ian.M on October 09, 2012, 07:11:25 pm
Andy,yes I think it maybe coming out faster
What could this be?

Have you checked the pressure at the tap? I had the same problem and found out most RO systems dont work under 40psi. I put a booster pump inline and have boosted my pressure from 35psi to 80 psi and am now getting 006 tds into tank.

If the pure water is coming out faster than before it could be a waste pipe problem.
If you have a valve on the waste pipe make sure it's not closed too far and check there are no kinks in your waste pipe.

No problem with the water pressure since going wfp.no valve on the waste pipe,it is just one inlet on a manifold on the side of the van (brodex standard issue)

Have you connected your water hose to the waste pipe by mistake and running the water through the ro the wrong
way. John.

unfortunately brodex only fit a sediment filter so your r o wont last long

You're joking - surely.

Alf.
If you dont have a adjustable waste valve how to you control your pure to waste water ratio?
As your ro gets older it helps to run more water to waste to keep the tds lower.

John,
       With the brodex system you simply put one hose in the inlet
And one in the RO unit turn the tap on and it flushes it out.no valve that I'm aware of?! Hope I'm explains clear enough!

From 450 tds your  R O should produce at least 45 tds, at 70 your resin  will not last long.  I think your resin is spent due to your tds been so high.   Have you ever flushed your RO. And have to taken a look at your r o membranes they could be split.AS this would have an impact on the flow and an higher tds.

Christ is that for real?so basically ill be forking out for a new RO then?!

Resin was changed about 6ish weeks ago.i flush this system almost daily ,not taken a look at the ro membranes

dont upset him to much he will be running back to brodex with a shotgun tommorow/i think you need a new bag of resin

  Hi Alf,  on the on side of your brodex 500 ro, where your water flow controller is, to the left of the controller the two glass water gauge's,  the left water gauge shows your pure,  the right hand gauge shows waste,  the right
hand waste gauge should have a adjustable waist valve on it, when flushing your ro the adjustable waist valve should be used.  when used for normal window washing the water level in both glass water gauge's should be level side by side using the adjustable waist valve, so your system should be running on a 50/50 pure to waist ratio.

hope this helps regards lal

I would have thought that the most important filter would be a carbon block over a sediment filter.

As you can get a CB filter to 5 micron I would go this way and use the CB filter as a sediment filter as well. Best option though would be to add a seperate filter elsewhere and have a conventional sediment filter first followed by CB after then R/O.
