  Very cool! The folks at ASU's Research Center in Tempe, AZ are wonderful hosts for this highly popular training. This class is the culmination of 35 years of training thousands of RO water treatment professionals worldwide, with ongoing refinements made each time. I am extremely proud to be a part of this!

  This was very informative. I had used ORP measurement with Arduino to automate dissolving ozone in an aquarium. ORP measurement in an aquarium, especially if you've got it on an IOT setup, would also give you a pretty good indication if something has died and negatively affecting the water column such as increasing the ammonia levels.

  While chemical cleaning make sure that water pass on product or permeate line u can adjust it in reject valve,coz some of membranes are hard scaling and water not pass in product line,.u can adjust it in reject valve.
