Winery`s New Wastewater Treatment Solution Exceeds Expectations
A partnership between Rombauer Vineyards and Cambrian Innovation demonstrates the efficacy of anaerobic/aerobic treatment during crush season.
Like with many wineries, not every drop of Rombauer Vineyards' delicious chardonnay and exquisite merlot can be captured in bottles. Through standard rinsing and cleaning processes this leading Napa Valley winery produces high-strength wastewater - effectively diluted wine. The resulting effluent has high levels of biological oxygen demand, a measurement of the organic matter and nutrients in a wastewater stream that can strain traditional municipal treatment plants. In 2009, Rombauer Vineyards
installed an aerobic wastewater treatment system to tackle this wastewater stream. By 2017, this system was unable to accommodate the high-volume swings of harvest season at the winery. The capacity limitation forced the winery to hold and haul excess wastewater to the East Bay Municipal Utility District (EBMUD). Trucking and treatment became high monetary, operational, and environmental costs for Rombauer Vineyards.
In 2018, Rombauer Vineyards uninstalled the existing, ineffective treatment system and replaced it with an EcoVolt® Solution. The new Cambrian Innovation® treatment system is a two-step treatment process: the first step is bulk BOD removal through one anaerobic EcoVolt Reactor; the second step is final polishing through one aerobic EcoVolt MBR. The system is powered and controlled by a C3 (Command, Control, Communications) Hub, Cambrian's centralized operations station that distributes power through the rest of the system and allows for simplified installation, automated operations, and remote monitoring. The solution treats 100% of the winery's wastewater and can easily expand to accommodate any increases in wine production.
