Bottling involves production and bottling of soft drinks (such as colas and sodas) and juices. Wastewater, generated from the bottling plants during production and cleaning operations, tends to be high in sugars and low in suspended solids (except in juice plants, where solids may be high). Due to the large volume of wastewater generated at such facilities and the high sugar (organics) content, Headworks AnMBBR™ (Anaerobic MBBR) is the ideal process to remove bulk (70 – 90%) of the organics without any aeration. The resulting savings in energy costs is a significant benefit to the bottling plants. In addition, biogas is generated in the AnMBBR™ process, which can be used to supplement heating gas used in the facilities.
The AnMBBR™ process may be combined with the aerobic MBBR process to reach low effluent BOD/COD values required for discharge. The combination of anaerobic and aerobic MBBR processes for bottling plants results in a very small footprint when compared to other conventional technologies at a fraction of energy costs as well as low sludge production.
By recovering the energy from the wastewater using the anaerobic process, the wastewater treatment facility can become a carbon-neutral facility.
