Title: brodex RO
Post by: R.L Window Cleaning on April 11, 2015, 02:20:26 pm

Hi i have a brodex 650ro system.

My tap water reads 100ppm
The ro membrane is 014ppm
The water in the tank reads 005ppm
And the water at my hose reads 025ppm

Seems odd that from the tank to the hose it shoots up.   

I have just fhanged the DI resin also.

Any help or advise?

Thanks

I have same system - Is your di flushed through - if not - let a good few gallons go through the brush and check again - and did you connect the in and out on the di head correctly - sorry if that sounds silly but worth a check

Hi there, how's the system setup is it di on filling up the tank or on the way out?

Try using another tds meter because 14ppm from 100ppm the membrane is way under performing. The rejection rates are below 90% and that's a issue on its own. Start by using a second tds meter firstly and go from there.

How old is the membrane ?

When I purchased a new one, Desal, reckon 18-24 months before new one is needed.

Before you buy another one,  get some calibration solution and check the meter you've got -  buying a new one is no guarantee it's going to be accurate
