White Paper: General Electrochemistry
By PEPCON Systems
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.

Application Note: Protecting Against Zebra And Quagga Mussels
By Amiad Filtration Systems
Zebra and quagga mussels are tiny invaders that present a huge threat to intakes, valves, pumps, and even some filtration systems.

Though the fast-growing colonies can overwhelm many defensive systems, automatic self-cleaning filters can provide chemical-free protection from zebra and quagga mussels.
