OXIDATION

Oxidation is any chemical reaction that involves the moving of electrons. Specifically, it means the substance that gives away electrons is oxidized.

BDD anodes generate highly reactive OH° radicals directly in water. These very strong oxidizing agents can destroy substances which are difficult to degrade with other methods.

In waste treatment we have the challenge of removing COD and/or TOC and also substances like cyanide as well as non-biodegradable, toxic organics, EDTA or surfactants.

Most of these substances can be degraded by oxidation processes.

BDD systems are the first choice when it comes to treatment of liquid waste which is difficult or too expensive to dispose of.

In some cases, a partial oxidation can be done to increase bio-availability of phosphate or nitrate, thus opening a low-cost path to treatment in biological sewage treatment plants!
