Turning Wastewater into Value with MET Technology

Discover how METzero’s cutting-edge Microbial Electrolysis Technology (METs) empowers industries to recover valuable resources, increase capacity, and reduce operational costs.

Microbial Electrolysis Technology

Our pioneering Microbial Electrolysis Technology (MET) turns wastewater from a costly burden into a source of energy, value, and opportunity. With industry-proven results, our approach helps companies reduce energy consumption, increase capacity, and recover valuable resources like hydrogen and more.

Benefits

Cost Savings

METzero eliminates energy-intensive aeration in wastewater treatment, which typically accounts for 50%-60% of energy use. It operates at ambient temperatures, avoiding energy costs for heating. This technology reduces indirect greenhouse gas emissions by decreasing energy consumption, allowing facilities to save up to £0.5 million annually on energy bills and cut GHG emissions by up to 30%.

Increased Capacity

METzero features a flexible design that can be retrofitted into existing treatment plants or deployed in modular units, improving capacity over time. It effectively treats high-load sludge liquors rich in ammonia and phosphorus, potentially reducing the systemic load by 10-20%. This adaptability allows for seamless integration, whether the return line is treated within the main system or separately.

Resource Recovery

METzero specialises in extracting valuable products such as hydrogen and ammonia from waste streams, customised for client needs.

Our pilot reactors successfully recover these resources, which can enhance biogas injections and assist in decarbonising operations and fleet vehicles.

How it works

METzero harnesses the power of Microbial Electrolysis Cells (MECs) to treat wastewater in an innovative way. Our technology utilises naturally occurring electrogenic bacteria to digest organic waste anaerobically.


These bacteria donate electrons to an electrical circuit during this process, producing a small current. To enhance the efficiency and output of our system, we apply a controlled potential difference across the electrodes. This adjustment allows us to generate various valuable by-products at the cathode, such as hydrogen and ammonia, directly from the treatment process.
