Title: Flexible Distributed Energy & Water from Waste for Food and Beverage Industry

Food and beverage plants inherently consume a large quantity of water and generate a high volume of wastewater rich in organic content. On one hand, water discharge regulations are getting more stringent over the time, necessitating the use of different technologies to reduce the amount of wastewater and improve the effluent water quality. On the other hand, growing energy and water costs are driving the plants to extract and reuse valuable energy and water from the wastewater stream. An integrated waste-tovalue system uses a combination of anaerobic digester (AD), reciprocating gas engine/boiler, membrane bioreactor (MBR), and reverse osmosis (RO) to recover valuable energy as heat and/or electricity as well as purify the water for reuse. While individual anaerobic digestion and membrane bioreactors are being used in increasing numbers, there is a growing need to integrate them together in a waste-to-value system for enhanced energy and water recovery. However, currently operation of these systems relies heavily on the plant operator to perform periodic sampling and off-line lab analysis to monitor the system performance, detect any abnormal condition due to variations in the wastewater and decide on appropriate remedial action needed. This leads to a conservative design and operation of these systemsmore » to avoid any potential upsets that can destabilize the system.« less
