Pilot-testing green technology
Odense Waste Management Company Ltd. and Aquarden Technologies ApS has started working together on a project to test a new, better and more sustainable way to treat contaminated rainwater that leaches through landfills of household waste. The objective is to discharge the leachate directly to the sea instead of sending it to municipal biological treatment facilities.
Aquarden’s SCWO technology is designed to deal with such challenges and is particularly suitable for treatment processes that require destruction of persistent organics in liquid waste.
The Aquarden reactor simply burns off all problematic compounds like ammonia and PAH (Poly-Aromatic Hydrocarbons) and transforms them to harmless CO2, N2, and water. Any heavy metals and salts are concurrently extracted. The end result is pure water.
An exciting potential
The test period will run for the next two years and Rasmus Olsen, Operations Engineer at Odense, expects that cooperating with Aquarden will allow Odense to optimize their treatment method: “We look forward to working together with Aquarden Technologies on this project. It is exciting, and the potential is big as we would be able to discharge large parts of our leachate as clean water directly to the canal system instead of sending it to the local WWTP as we do today.”
As Mr. Zhuoyan Cai, director of Aquarden Technologies states: “It is a great opportunity for us to participate in this pilot project with Odense as we are able to demonstrate the unique purification capabilities of our eco-efficient technology on leachate in real life. We know that landfill operators face increasing pressure to minimize and even eliminate problematic substances and we see it as our mission to help landfill operations to be on the forefront of legislation. We are confident that the results will exceed the expectations”.
The project is funded by The Danish Ministry of the Environment under the EU-program named Ecoinnovation and is granted environmental technologies that either directly or indirectly improves the environment. A total of DKK 885,000 has been allocated the project.
