Thad,
Thank you for calling me back. As I mentioned, we installed a Cot based pH adjuster for our Morrisville site on
3/21/18. The pH adjuster circulates the water in our pond; while doing so it injects Cot into the circulation which
treats the entire pond prior to discharge. The pH adjuster not only lowers the pH of the water to the allowable range, it
also reduces the solids content of the discharge by 99%.
Please let me know if you have any other questions,
Thanks,
Johnie
