Parts Per Million (PPM) is a unit of measurement used to express the concentration of a substance in water, air, or other mediums. In plumbing and water treatment, PPM is often used to measure the concentration of contaminants, such as chlorine, lead, or other dissolved solids in water. It provides an accurate way to assess water quality and ensure compliance with safety standards. Monitoring PPM levels helps in adjusting water treatment processes, such as filtration, disinfection, or chemical dosing, to maintain safe and clean water.
