Actually you do and if not the equipment you need is easy to obtain and inexpensive. You will need a turbidimeter, a vacuum aspirator for a sink, vacuum flask and a Millipore vacuum funnel. This is the very same equipment needed to run a SDI. If you have RO's and are not running SDI's on the water going to the RO's, you are making a grave mistake. Your UF membrane will have performance specifications. Get Millipore filters of the same pore size. Then run filtration tests of the feed to the UF. Weigh the pads before use and let them dry at 150F. Time how long it takes to filter 1 liter of water. Use the before and after weights to determine how much material was filtered. Send the filter pads to a lab for analyses. That will get you started. This gets me back to my original Post. "Why?" If you have membrane equipment, why are you not tracking its performance? Having an RO and not running SDI's is asking for maintenance trouble.
