RO - Too much waste water?
« on: February 23, 2012, 10:54:28 pm »
Been producing some water today, TDS is at 003 for some reason and the waste water is nearing on twice that of the pure, any ideas?

I will check tomorrow but from memory about 165?

The waste is normal at 2:1 Waste:Pure as well?

Thanks Ian.

We run a variety of systems.  Our pumped 40-40 runs at 2.25:1 Input 285-305  output 5-6  HF5 membrane about 2 and a half years old.  Producing 1000lt in about 8-10 hrs.

Others are mostly Pure Freedom and Cleaning Spot - basically the same systems, all run at 2:1 and produce at about 15 ppm from the same input.
