The treatment process at this King City winery consists of two lagoons in series. The first lagoon, with a 14.5 ft side water depth (SWD), is where the majority of the treatment takes place. The influent from the facility runs through a rotary screen before entering the first lagoon. A return active sludge (RAS) line discharges near the influent entering the lagoon. The wastewater is treated with a fine bubble aeration system before entering a second lagoon. The second lagoon acts as a polishing basin with a SWD of 10 ft. The wastewater is again treated with a fine bubble aeration system. The RAS is collected at the end of the process and returned to the front of the plant.
Based on this layout, the winery facility needed a blower solution that could be located outside, next to the basins, without a cover and without being a noise nuisance.
Additional realized costs savings came from being able to locate the blowers outside, alongside the basins. The need for a blower building was eliminated, as was the need for long runs of piping to connect the process air to the aeration system, which dramatically reduced the construction costs associated with the earth work, foundations, and engineering required for such a building or piping. The Inovair blower units also offered smoother, quieter operating noise levels than competing products, reducing safety concerns.
