  • General Electrochemistry
    General Electrochemistry

    All chemical processes involve the loss, gain, or redistribution of electrons on an atom or group of atoms. Electricity is the movement of electrons along a conductor. It is no wonder then that chemical changes can be made to occur by passing an electric current through a solution containing atoms or groups of atoms which will accept or give up electrons. Processes which pass an electrical current through a solution to effect chemical changes are called electrochemical processes. By PEPCON Systems

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
