"This (Lyve) type of system is what we will likely see more of for win- ery wastewater systems." ALPHA OMEGA SYSTEM Alpha Omega Winery in Ruther- ford installed a Lyve L25 unit with a 6,000 gpd capacity in August 2009. The steel aeration and clarifier unit was fabricated in New Zealand, then shipped to the winery where it was installed by a crane onto a concrete slab. The system footprint is 8 feet x 22 feet (176 square feet) and 11 feet high. The winery chose a Lyve system in order to expand its wine produc- tion and wastewater processing capacity, without sacrificing space from its vineyard or the tasting room parking lot. In addition to processing waste- Also: Megaquant Meter for wineries without UV/Vis spectrophotometers DISTRIBUTED BY VINOTEC NAPA CALL 707-953-7072 email napazyme@aol.com www.vinotecnapa.com 94 VINEYARD & WINERY MANAGEMENT JULY - AUG 2012 water from wine production, the system was also designed to han- dle domestic wastewater from the winery office and tasting room. For- merly, domestic waste was man- aged with septic tanks and leach lines. Now, domestic waste goes to the septic tanks for temporary stor- age, but is then combined with the winery wastewater in a 5,000-gal- lon equalization tank. "Comingling domestic waste with process wastewater, we find it can be ben- eficial from a biological standpoint, as it provides nutrients that we may otherwise have to add," August explained. The system treats the water to BOD and TSS requirements in 24 hours. Treated water goes to the existing wastewater pond where it is stored for vineyard and landscape irrigation. Sludge from the Lyve unit goes to a 3,000-gallon sludge tank where it settles from water and is hauled to a landfill about every two months. An enclosure on the Lyve unit has a touch-screen, computer- driven control panel for making onsite adjustments. A video cam- era is mounted above the aeration basin to remotely view water levels and conditions. "By looking at the foam on top of the water, we can tell if the water is nutrient-deficient and the condition of the system," August said. The control unit has an alarm system to notify operators remotely if the system is exceeding capacity, or if a problem occurs. For more information, visit www. lyvesystems.com.
