PPM also known as Planned, preventative maintenance or as planned maintenance, scheduled maintenance, PPM maintenance or preventive maintenance. With this form of maintenance, equipment and building fabric inspections and testing are undertaken at regular intervals by specially trained engineers to prevent the potential for breakdown, confirm safety and ensure it is efficient in operation. TDS stands for “Total Dissolved Solids,” a measurement of the various minerals, organic, and non-organic matter present in water. PPM refers to “Parts Per Million.”. Since these solids are microscopic, a single sip can contain hundreds of thousands of molecules.

PPM (Parts per million) is a measurement used today by many customers to measure quality performance. Definition: One PPM means one (defect or event) in a million or 1/1,000,000 There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM.

According to the EPA secondary drinking water regulations, 500 ppm is the recommended maximum amount of TDS for your drinking water. Any measurement higher than 1000 ppm is an unsafe level of TDS. Difference Between ppm and ppmv ppm vs ppmv Both “ppm” and “ppmv” are abbreviations used in scientific calculations. They are dimensionless quantities. While using these terms one should be very specific and not be confused in using one in place of the other. ppm “ppm” stands for “parts per million”.

(A part per billion is 1,000 times smaller than a part per million) 1 part per million is the equivalent of 1mg of solubles per liter of water which is a minuscule amount to measure! Drinking water tested in the US can measure as low as 0ppm (for reverse osmosis, or distilled water) or as high as 700ppm (very poor quality tap water), but most tap water will fall in the 200ppm-400ppm range.
