Positive early results for first UK Nereda pilot plant installation

Posted: Wednesday 24th December 2014

Imtech Water, Waste and Energy (Imtech), is pleased to announce that early indications from its’ first Nereda® pilot plant are looking very promising. Working closely with United Utilities’ Innovation Team, Imtech has installed the pilot plant at United Utilities’ largest wastewater treatment works, Davyhulme in Manchester. This is the first Nereda pilot plant installed in the UK and it introduces a step change for the industry.

With initial results showing that the plant is achieving biological treatment to less than 0.5 mg/l ammonia and 0.5 mg/l phosphorous, Imtech and United Utilities are delighted with its’ early performance. In addition to the higher effluent quality being produced, the Nereda technology also offers lower CAPEX and OPEX benefits.

Nereda is an award-winning, innovative wastewater treatment technology, which is easy to operate, cost-effective and sustainable. After many years of research and development by Royal Haskoning DHV and the Dutch water sector, this innovative biological treatment solution offers significantly lower investment and operational costs, reduced physical footprint, high energy savings (20-30%), and minimal or no chemical usage, together with industry-leading levels of wastewater treatment. Nereda is proving to be the next leap forward in high-quality, low-cost, sustainable wastewater treatment technology.

Commented Duncan Atkins, recently-appointed Managing Director at Imtech Water, Waste and Energy: “When Imtech was first introduced to Nereda we recognised the potential offered by the new technology. We were pleased to be awarded the sole UK license, as it represents the first significant step forward in wastewater treatment since the introduction of activated sludge.”

Kieran Brocklebank, Head of Innovation at United Utilities added: “We use a number of our key sites for testing new technology across the North West, and the team at Davyhulme have a culture of embracing innovation – after all, this is the site where activated sludge was developed 100 years ago, so it is fitting that a century later, we are the first company in the UK to trial the next evolutionary step. The initial results are exciting and we are looking forward to continuing our evaluation of this emerging technology.”
