RO MEMBRANE DIAGNOSTICS

Although RO membranes are capable of maintaining high water quality over extended periods of time they eventually will begin to deteriorate. Normally, the conductivity of the permeate water will increase as the membranes age. By comparing the difference in TDS readings between the Tap water conductivity and the RO water conductivity, the per- centage of rejection of the RO membrane may be calculated and the resultant number may then be used to determine the condition of the membrane and thus the operator will know when the membrane needs to be replaced. Membrane failure will be indicated by a reduction of the percentage of rejection which will be determined by calculating the dif- ferential between the input and output numbers.

In order to accurately determine the condition of the RO Membrane, a conductivity tester (TDS meter) capable of reading the tap water

conductivity and the permeate water conductivity has been provided with this system. With the assistance of the TDS meter you will be able to easily determine the RO membrane’s condition. (see page 7)

Before performing the diagnostic test on the RO membrane, make sure that the RO system has been “ON” and producing pure water for a mini- mum of 10 minutes. Also check the brine (yellow) line to make sure that water is flowing and that the flow ratio between the permeate water and the brine water is at a ratio that is > 4 to 1. ( See Page 9). (NOTE: The pressure gauge should indicate a pressure reading of > 40 PSI during this 15-20 minute test period.

Procedure:

1.Turn on the meter 1 by depressing the on switch.

2.Locate the meter slide switch on the front of the DM-1 TDS meter.

3.Slide the switch to the “Left” and read the Tap water conductivity then record the reading ________ .

4.Next, slide the switch the to “Right” and read the permeate water conductivity then record the reading ________.

5.See page 7 on “TESTING THE RO MEMBRANE REJECTION RATE ”
