The Effects of High Conductivity in Boiler Water Treatment

The presence of high boiler water solids creates foaming, which reduces the efficacy of the boiler. High levels of salts, heavy metals, and other substances in water can be somewhat toxic to a person's health if consumed in high amounts. The dangers to a person's health extend from skin irritations to gastrointestinal issues.
