Reduced COD More Than 90% for Water Reuse & Vine Irrigation
Project: bioPULSE™ MBR for California Vineyard Production
Industry: Food & Beverage; Craft Beverage
Application: Biological Oxygen Demand (BOD)/Total Suspended Solids (TSS) Removal
Problem: A vineyard located in California installed a bioprocessH2O wastewater treatment system to reduce BOD/TSS from the wine processing waste and to use the system effluent for vine irrigation.
Solution: To achieve the vineyard’s objectives, bioprocessH2O supplied a bioPULSE™ Airlift Containerized Membrane Bioreactor (MBR). The MBR incorporates an energy efficient airlift external tubular and backwashable membrane that significantly reduces power consumption. Due to site constraints, bioprocess installed the UF membrane system, PLC control panel and chemical feed assemblies within a customized 20 foot long container. The fiberglass process tanks (equalization, aeration and sludge holding) were existing at the vineyard and used for the MBR system. The treatment process is fully automated using an Allen Bradley PLC controller that allows remote monitoring via an internet connection allowing bioprocess to provide operational oversight and assistance. The permeate produced by the MBR is UV disinfected and being used to irrigate the vines.
Status/Results: The MBR has proven effective at reducing the BOD, COD and TSS from the vineyard’s wastewater. The following table summarizes the design criteria, influent and effluent quality measured to date.
