Hello can anyone explain this to me, i have a mini ro system as back up from pure fredom i made 10 buckets of water up using warm water
i connected this up to the hot water feed from my washing machine
The readings when done ranged from 1 - 3 ppm
I microwaved some and it went upto 5 ppm
Will this water go back to 0ppm
It made the water twice as fast
I cant work this one out
I think that someone explained it on here just recently. A PPM reading results from passing a minute electrical current through water to measure its conductivity. Water with less impurities will be a poorer conductor of electricity than water with more impurities.
But warm water can throw the readings out as current travels easier through warm water than cold as warm water is less dense than cold water (very cold water is a solid - ice). It could also be that the water has been 'contaminated' in the microwave, either from the container used or from the air being drawn in from outside.
If you are reacting to the increased speed at which the RO worked with warm water, then this is experienced by each of us every year. It takes longer to process water through the RO in winter than it does in summer as the water is more dense in winter. When the weather is good in winter our 450 gallon RO can just keep up with the 2 of us with a bit of planning, but have no such issues in the summer, even although we use more water as we work longer hours.
I would suggest that you check what the maximum temperature of the water your RO membranes will work at, as I understand that they can be damaged if the temperature is too high.
