Beer & Beverages

Major advantages of GWE’s solutions:

• Generation and collection of valuable biogas that can be used as a carbon-neutral energy source (for steam production in boilers; for hot water and electricity production via a Combined Heat Power (CHP) unit);
• Minimal WWTP operating costs when compared to aerobic wastewater treatment technologies;
• Further polishing steps available for water reuse, such as a Membrane Bioreactor (MBR) and Reverse Osmosis (RO) system;
• Remote monitoring and Operations & Maintenance support from GWE;
• Sustainable and award-winning waste-to-energy technologies from GWE.

Renewable energy from wastewater

Anaerobic treatment has developed in recent years as the wastewater technique choice of the companies generating high organic content wastewater. Many soft drink and non-carbonated beverage (tea, coffee- and milk-based drinks and fruit juices) production, bottling and canning plants have increasingly been choosing anaerobic treatment for their wastewater.

Our ANUBIX™ family of anaerobic reactors (GWE offers both UASB and EGSB-type reactors) provide an integrated solution for the wastewater and energy needs of beer & beverage production plants. These advanced biological wastewater treatment systems use anaerobic bacteria in a closed reactor to degrade the organic compounds in the wastewater and convert them into biogas and clean effluent.

The biogas can then be used as a source of energy for the generation of hot water, steam or electricity, thus supplying a portion of the energy needs.

Another advantage of such advanced anaerobic wastewater treatment, is that it significantly reduces a carbon footprint by avoiding CO2 being released into the atmosphere, as would be the case when using fossil fuels instead of biogas, when using a high-power-consumption aerobic form of treatment, or when using a greenhouse gas-emitting form of treatment such as an open lagoon.
