Wastewater from winery processes such as tank cleaning, grape crushing, barrel washing, and equipment/floor cleaning is treated using a bioreactor. The treatment consists of collection of wastewater in floor drains, discharge to a settling sump, rotary screening, biological treatment in a bioreactor,pH neutralization, clarification, and land application. Applied wastewater will be mixed with supplemental irrigation water. Sludge from the clarifier will be recirculated to the bioreactor or wasted. The location of the land application area is presented on Attachment B, which is attached hereto and made part of this Order by reference 8. A mobile contract wine bottling service will perform bottling. The bottles arrive at the site clean and no rinsing occurs prior to filling. Therefore,bottling activities will not generate a high strength waste stream. 9. The Discharger does not have the means to store wastewater during rain events. 10. With the exception of the land application portion of the wastewater treatment system, all the wastewater treatment takes place in above ground tanks or concrete lined sumps. Screened solids are deposited directly into bins and wasted sludge is applied to the land application area. 11. The treatment system is anticipated to reduce the concentration of Biochemical Oxygen Demand (BOD) from 10,000 mg/L to 600 mg/L. Combined with the size of the land application area, it is anticipated that odors will not be generated by the discharge. Biological treatment is also likely to reduce total nitrogen concentrations.
