EC results?






Shortly we are going to be running some Electro Coagulation trials at our workshop using a unit from the states, and I was wondering if anybody had any results form previous applications of this process. Any figures you may have lying around would be greatly appreciated, it would help me get a better feel of the use and capabilities of one of these things.

You haven't given us any clues toward what you are doing yet, Matthew, so that your question is a bit like asking people for any figures they may have from the use of tomatoes :-)

Ha ha! I would appreciate any EC results on tomatoes! But seriously, I am open to any EC results, I just want to get a feel for what areas it is good or not so good. Our expected feed contains a lot of heavy metals, so that is my main concern, especially the coagulation of heavy metal ions out of solution. I would love any results on EC performance with completely dissolved feed, with no solid content whatsoever (or oil content). If anybody has any, that would be great!

Do an internet search using "electrocoagulation" and you will find a few tables of results. It works best if the pH is lower than 9, and 5-7 is optimum. Do not use aluminum or mixed steel and aluminum plates for best results with heavy metals. The retention time in the electrical field is critical - look for less than 30 seconds or you will have great difficulty in a full-scale unit. There are more suppliers of electrocoagulation than there are effective systems. Get a performance guarantee!

The EC means sacrificial electrodes, temperatures, pH and concentration dependence. Why not try to use ECP (electrolitic catalitic precipitation) which means non-sacrificial electrodes, and does not depends on pH, temperature and concentration, the process it is oxidation and the results are precipitated solids like heavy metals oxides, filtrating solids.

Sorry! Finishing.com is temporarily Read-Only.
Ted Mooney is retiring but I have several offers to take it over.
We're working hard to make sure we find it the best new home.
