PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

High quality water is recovered after reducing the TMAH concentration to 1 ppm and lowering the TOC to 0.8 ppm from 8 ppm. For the industrial scale TMAH

A natural ground water containing 16 ppm of ferrous iron when collected, and 9 artificial solutions containing from about 12 to about 26 ppm of ferrous iron at pH 5.8 to 6.7, lost iron by oxidation and precipitation of ferric hydroxide at a rate governed by the diffusion of oxygen through the water.

One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg). 2020-03-25 · In our experience, water over 100 or 150 ppm (approximately 8 – 10 grains/gallon) is hard enough to warrant water softening. Why is water hardness important? When hard water is heated, such as in a home water heater, solid deposits of calcium carbonate can form.
