Puretec’s chart converts water quality measurements to serve as a comprehensive guide for understanding and converting key water quality parameters. The chart includes resistivity, conductivity, total dissolved solids (TDS), and Grains per Gallon (GPG) which are crucial metrics for determining water purity in various industries. It also features a detailed pH scale, illustrating the range from acidic to alkaline conditions, and how these levels impact water quality. This resource is particularly valuable for industries like pharmaceuticals, microelectronics, and power generation, where precise water quality is essential.

The chart converts water quality measurements, covering several key water quality parameters:

  1. Resistivity: Measured in ohm-centimeters, resistivity indicates the water’s ability to resist the flow of electric current. High resistivity suggests low levels of ionic impurities, which is crucial for processes requiring ultra-pure water.
  2. Conductivity: The inverse of resistivity, conductivity measures the water’s ability to conduct electricity, expressed in microsiemens per centimeter (µS/cm). Higher conductivity indicates more dissolved salts or ions, often used to estimate the total ionic content in water.
  3. Total Dissolved Solids (TDS): Represented in parts per million (ppm), TDS quantifies the total concentration of dissolved substances in water, including minerals, salts, and organic matter. It is a key indicator of water quality, especially in industrial applications.
  4. Grains per Gallon (GPG): While grains per gallon (GPG) and parts per million (ppm) are both used to describe the dissolved hardness minerals contained in a water, PPM is a unit of a substance out of one million units of water, whereas GPG is a unit of weight. One grain per gallon (gpg) is equivalent to 17.1 parts per million (ppm).
  5. pH: The pH scale ranges from 0 to 14, with 7 being neutral. It measures the acidity or alkalinity of water, with values below 7 indicating acidity and values above 7 indicating alkalinity. Maintaining the correct pH level is crucial in many industrial processes, including water treatment and chemical manufacturing.

Each of these parameters plays a critical role in water quality management, helping industries tailor water treatment processes to meet specific requirements. The chart converts water quality measurement, serving as a practical tool for industries who need to meet the stringent standards required for various applications.
