Join Water Vision Inc on February 14th at the Produced Water Society's 2018 Seminar. Our CTO Dr. Mitch Means will be presenting "Making Electrocoagulation Commercially Viable."
Abstract of the presentation:
Electrocoagulation (EC) is a water and wastewater treatment process that has been a standard in multiple industries since the 1800s. The main objective of the technology is to destabilize and aggregate contaminants, separating these flocculated materials in tandem such that the materials can be easily removed to leave clear water.
Traditionally, the complex electrocoagulation process has relied on power-stimulated sacrificial anodes and cathodes facilitating the water treatment operation. The process has been effective in a variety of applications because of the broad range of contaminant sizes - from sub-molecular to macro particles - and the large number of contaminants that it can address. Examples of EC's continued use would include oil & gas produced water, municipal wastewaters, and a broad spectrum of industrial process and wastewaters.
Even though traditional EC technology has proven to be effective and has several advantages over alternative water treatment methods, it suffers from a limitation known as passivation. This limitation causes scaling, oxidation and pitting of the sacrificial electrode plates used in the process. This can result in reduced treatment effectiveness and can impact treatment operations. The most notable disadvantages include an increase in power costs, excessive downtime, increased maintenance manpower, and potential safety issues.
The presentation will highlight some new advances in electrocoagulation technology and its complex electrical and chemical processes. It will define the key parameters that influence the EC process, review the reactions during its application, and demonstrate its advantages in comparison to other EC technologies.
In addition, this presentation will also fully examine the solution to electrode passivation and how these factors lead to the development of a commercially viable EC water treatment system. Visual examples of passivation will be shown in parallel with the multiple stages of the EC process, and a graphic example will underscore the impact of passivation on the EC process's electrical power usage.
