Sad but true Tom, you would need a lawyer go over your system with you if you wanted to use Floccs similar to Parker West. They have been issued the US patent and if they have "just cause" they could go after whom ever they think is infringing upon there patent.
I have heard that the Flocc's method do not always pass the required testing. (But in most places they dont even check). There are so many variables in the wash stream that sometimes the sludge does not pass.
You hit the nail on the head with EC technology, it is fast becoming the wave of the future. The military is in the forefront. When last I checked it cost, ..hold on to your hat...
$30,000 for a system to process 15-17 gpm
