Anodic protection (AP) is a technique to control the corrosion of a metal surface by making it the anode of an electrochemical cell and controlling…

Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. It…

The galvanic series determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external…

A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion. They…

Galvanic corrosion refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte. It is an electrochemical process in which one metal…

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. It is an…

An anode is an electrode through which the conventional current enters into a polarized electrical device. In the most basic form, an anode in electrochemistry…

An evaporative cooler (also known as swamp cooler or wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling…

Electrodeionization (EDI) is an electrically-driven water treatment technology that uses electricity, ion exchange, and resin to remove ionized species from water. It uses no chemicals…

Dehumidifiers reduce humidity levels, making your home less hospitable to allergens such as dust mites, mold, and mildew. It is a device that removes excess…

Capacitive deionization (CDI) is an emerging and promising new technology for the removal of ionic as well as polarizable species from water. It is a…

Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential…
