TDS readings
ALright! The easy way is to use an electronic TDS meter. Or, a well mixed sample is filtered through a standard glass fiber filter, and the filtrate is evaporated to dryness in a weighed dish and dried to a constant weight at 180 degrees C. The increase in dish weight represents the total dissolved solids. The meter might be easier. The latter method is taken from "Standard Methods for the Examination of Water and Waste Water, 20th ed."
