Truly an amazing chemistry to bring back the value of a filter’s components. I experienced it myself at a 6 mgd PRASA plant back in 2016. Within 3 days, the plant placed back all 6 filters saving over $150k in multimedia replacement. The investment…$18k plus 2 workers for 8 hrs and 3 days. Nothing to dispose of, no heavy machinery and no time lost. All of these was achieved with the knowledge, and support of Matthew Seeker remotely. Safe, effective and reliable product.
