Description

We are inviting suppliers to share information on alternative wastewater disinfection technologies. This notice is for market engagement only. It will not necessarily lead to procurement. Across the UK there are more than 600 designated bathing waters, and several shellfish protected areas. These require effective wastewater disinfection to protect both the environment and public health. At present, only ultraviolet treatment and membrane filtration are formally recognised. While proven, both approaches bring challenges: high energy use, high costs, and limited suitability for smaller or rural treatment works. We want to understand what other solutions exist in the market, both in the UK and internationally. This will help us build a clearer picture of what options could be available, what evidence already exists, and where there may be opportunities for collaboration. The insight we gather may also support future funding bids and trial projects. Alongside this notice we will be linking with industry experts and national research projects to make sure there is no duplication and to draw on existing knowledge.
