PENETRON crystalline technology was specified for a comprehensive upgrade of the almost 100-year-old Martinsburg Wastewater Treatment Plant in West Virginia. Martinsburg initiated the upgrade to help their facility comply with the latest EPA wastewater discharge regulations, specifically for phosphorous and nitrogen nutrients. The $53 million project included the integration of a new Moving Bed Biofilm Reactor (MBBR) system and numerous other process improvements, such as the new headworks facility, the primary and secondary clarifiers, effluent polishing system, solids dewatering facility, chemical feed systems, structural demolition and extensive site work.
To ensure durable and impermeable concrete structures, PENETRON ADMIX was specified and added to the concrete mix by Thomas Bennett & Hunter during the batching phase. Approximately 7,700 cubic yards (5,900 m3) of concrete were treated with the crystalline admixture and used for the new headworks facility, the MBBR system and the solids dewatering tanks.
