The City of Villa Rica, Georgia, located in Carroll County, has two wastewater treatment plants. The West WWTP is a new 2.15 MGD facility designed for future expansions. Key features of the plant design include: a new influent raw sewerage pump station; an oxidation ditch with a multi-stage selector ahead of the ditch for biological phosphorus and total nitrogen removal; secondary clarification; tertiary treatment, including tertiary clarification and a deep bed sand filter; an auto-thermal thermophilic aerobic digestion system (SNDR by Thermal Process Systems, Inc.); and a plant drain pump station.

Despite a serious event that could have had disastrous repercussions, the Villa Rica West WWTP never violated its Discharge Permit Limit for phosphorus. What could have easily been a three to four-month long nightmare to recover the biological portion of the plant was completely avoided within days due to the use of TPX™ crystals.
The financial savings to the plant were enormous. The cost of TPX™ product and technical support was a small fraction of the potential fines, expenses, and ongoing chemical costs that Villa Rica would have faced with alternative treatments. Even more important than the financial implications to the plant, TPX™ helped to avoid the detrimental environmental impact that months-long discharges of high phosphorus concentrations would have had on receiving waters.
According to Mr. Zorbanos, “TPX™ saved our plant. Without TPX™ we would have been out of compliance for months.”
David Henson, Villa Rica WWTP Superintendent, added, “With traditional chemical treatments, we are confident that we would have lost the plant. Losing the biologicals would have set us back months. I was extremely impressed with how well the TPX™ product worked, and with the support we received from the company.”
