[3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".
Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter. [1]
