Oxidant

  1. A substance that readily adds (takes on) electrons.
    • (DBP01) DBP Rule – Overview (1282)
  2. A substance that is used as an oxidizing agent, which causes a substance to lose electrons, changing its chemical nature.

Ozonation

The application of ozone to water for disinfection or for taste and odor control.

Ozone is an extremely powerful disinfectant and an excellent oxidizing agent.

WASTEWATER

Activated Silica

A coagulant aid that is created on-site by neutralizing sodium silicate.
