Description

As the Water Sector moves into AMP8, there are a significant number of phosphorus drivers, particularly at very small WwTWs. This presents the UK water Sector with a significant challenge. There is potential for introduction of chemicals on a significant number of small WwTWs, which raises health and safety concerns and results in high carbon, costly solutions that do not provide value for money for UK water customers.

This study investigates the adoption of Fujiclean at United Utilities. Fujiclean is a Japanese technology designed for domestic wastewater treatment. The compact, modular package plant system is capable of treating BOD, suspended solids, Total N, and Total P to high standards without requiring chemicals. Phosphorus removal is achieved using electrocoagulation, integrated directly into the system. Its modular design makes it ideal for upgrading aging septic tanks and underperforming small WwTWs, providing a low-energy, chemical-free solution.

The study will present data from an extensive trial led by United Utilities, in collaboration with Haigh, as well as the transition to a full-scale adoption strategy, supported by Jacobs. This includes a global-first municipal installation as part of an AMP7 scheme, showcasing the potential of Fujiclean as a sustainable, cost-effective solution for small-scale wastewater treatment.
